  • Wood biomass recovery from chestnut orchards: results from a case study
    • Authors: Carla Nati; Niccolò Brachetti Montorselli; Roberto Olmi
      Pages: 1129 - 1143
      Abstract: Sweet chestnut has been for many centuries essential to human diet in large areas of Southern Europe. Its cultivation was abandoned in the last century, but is at present under restoration for socioeconomic reasons, representing also an opportunity for allocating woody residues to the energy sector. A little is known from the literature about sweet chestnut pruning, and the aim of the study was to assess the biomass yield and quality, the productivity and costs of the system as well as its energetic balance between inputs and outputs. The yield of recovered wood material amounted to between 22.3 tonnes of dry matter per hectare (tdw ha−1) and 33.3 tdw ha−1. Time consumption for pruning has been related to trees’ DBH, so detecting a linear relationship, although weak, between tree size and the time spent for maintenance. Productivity expressed as tdw per hour varied according to the site and the operating systems adopted accordingly. Costs for the whole chain, excluding transport to the plant facility amounted to 113 or to 430 € t dw −1 depending on the terrain relief and the presence of an underbrush to be cleaned. Wood chips distribution in size classes provided a material unsuitable for non-industrial due to the percentage of oversize particles, probably due to the high presence of twigs. The energy ratio resulted of 30:1 and 21:1 for the two sites. Transportation had the main impact in terms of energy, followed by extraction and chipping phases.

  • Identifying barriers and motivators for adoption of multifunctional
           perennial cropping systems by landowners in the Upper Sangamon River
           Watershed, Illinois
    • Authors: Chloe M. Mattia; Sarah Taylor Lovell; Adam Davis
      Pages: 1155 - 1169
      Abstract: The demand on agriculture to meet food security goals and mitigate environmental impacts requires multifunctional land-use strategies. Considering both farmer motivations and rural development needs, one option is to transition marginal farmland to perennial crops. In this study, we considered the potential for Multifunctional Perennial Cropping Systems (MPCs) that would simultaneously provide production and ecosystem service benefits. We examined adoption potential of MPCs on marginal farmland through an agricultural landowner survey in the Upper Sangamon River Watershed in Illinois, USA. We identified adoption preferences among landowners in conjunction with socio-demographic characteristics that would facilitate targeted implementation. Hierarchical cluster analysis and discriminant analysis identified landowner categories and key factors affecting adoption potential. Landowner age, appreciation for plant diversity, and future farm management involvement were the strongest predictors of potential MPCs adoption. The landowner categories identified within the survey data, supplemented with focus group discussions, suggested a high adoption potential farmer profile as a young, educated landowner with known marginal land they would consider converting to MPCs for improved soil and water quality conservation.

  • Rehabilitation practices that shape cocoa agroforestry systems in Central
           Cameroon: key management strategies for long-term exploitation
    • Authors: Patrick Jagoret; Didier Snoeck; Emmanuel Bouambi; Hervé Todem Ngnogue; Salomon Nyassé; Stéphane Saj
      Pages: 1185 - 1199
      Abstract: In Africa’s main cocoa producing countries, rehabilitation of old cocoa orchards is increasingly debated but rarely adopted. In Central Cameroon, rehabilitation practices are regularly set up in old cocoa-based agroforestry systems (cAFS). To better understand the impact of such practices we built a chronosequence of 40 cAFS. We carried out specific surveys with farmers on each plot in order to check for rehabilitation effects on cocoa stands and associated woody species (AWS). We found that cocoa trees represented on average 88.2% of woody individuals and increased with age (from 84.7 to 91.5%). The cocoa stand basal area (BA) share significantly increased with age and reached up to 40.2% in the oldest systems. Cocoa, fruit and forest trees mean BA increased with aging. They were on average of 6.5, 5.7 and 10.7 m2 ha−1 respectively. Six different architectural types, different from the theoretical architectural evolution of cocoa trees over time, were identified. Among them, type 4 characterized by several orthotropic suckers of differing ages, was found typical of farmers’ cutting back practices. Type 4 cocoa trees density increased over time and its BA represented on average 60% of cocoa stand BA in the oldest systems. Concomitantly, farmer’s management of AWS led to continuous evolution of the systems both in terms of density and species composition. Our results show that (i) permanent densification and cutting back practices (type 4) allow the rejuvenation of cocoa stands while increasing cocoa stands BA share; (ii) the continuous management of AWS by farmers is undertaken to favour cocoa trees share over time by limiting inter-specific competition and promoting complementarity between cocoa trees and AWS. We argue that such practices explain a fair part of the long-term sustainability observed in cAFS from Central Cameroon and represent a model from which new rehabilitation schemes could be inspired.

      Abstract: To alleviate the combined effects of water and heat stress prevailing in drylands, the choice and introduction of appropriate plant species to these conditions is essential for the success of planting in rehabilitation projects. The argan tree (Argania spinosa) is a vigorous plant, admirably adapted to dry climates, with indisputable physiological and ecological characteristics that make of this tree an ideal plant to fight against erosion and desertification process, which seriously threaten arid lands. However, the geographical origin of seeds/seedlings represents a determining factor. In this context, we investigated the morphological responses of growth in two provenances of argan, the provenance of Tindouf ‘PT’ from Algeria and that of Agadir ‘PA’ from Morocco; under water stress conditions. The experiment attempts to evaluate the level of drought tolerance of these two provenances for selecting the planting material that copes and adapts better to hot arid lands. Argan seedlings of both provenances (PA and PT) were submitted to a water stress gradient (75, 40, 20, and 10% of field capacity), then morphological parameters (shoot height, number of leaves, number of spines, root collar diameter, length of taproot) were measured after 3, 6, 9 and 12 months of growth. All variables of morphological growth varied significantly (P < 0.001) between water stress levels, seed geographical provenances and seedling growth ages. The overall of results concerning morphological parameters indicated that the increase of water stress induced in both argan provenances: a decrease in shoot height associated with an increase in length of taproot that resulted in the reduction of leaf numbers and radial growth but the increase the number of spines. The argan plantlets of Agadir have completely failed to tolerate water stress of 10% FC. Under water stress (40, 20, 10% FC), argan seedlings of Tindouf revealed higher growth results than those of Agadir. PT seedlings offset the water deficit by root elongation to ensure growth of the various components of the aerial part. PT seedlings were more resilient to drought stress as compared to those of PA. The highest growth results were obtained with 40% FC in PT seedlings, and with 75% FC among PA seedlings. It is recommended to use the PT seeds in planting projects under drought conditions, while PA seeds are more suitable under conditions of non-water deficit.

  • Soil impact and radiation dose to native plants in forest ecosystem
    • Authors: P. K. Manigandan; B. Chandar Shekar
      Pages: 1213 - 1219
      Abstract: A radiation dose assessment model was applied to determine naturally occurring radionuclides 238U, 210Po and 232Th in trees like Elaeocarpus oblongus, Evodia roxburghiana (Juice of the leaves that are used to treat fever), Vaccinium neilgherrense, Viburnum hebanthum and Michelia nilagirica and shrubs like Lasianthus coffeoiaes and Hedyotis stylosa in the agroforests of the Western Ghats, India and these areas were used for different agroforestry models of land development systems. The concentration of radionuclides in the biota and corresponding soil was measured using a gamma ray spectrometer and an alpha counter. The concentration ratios of these radionuclides varied substantially between the species, and E. oblongus showed a preferential uptake of all the radionuclides and hence useful for bio-indication of radionuclides in such soils. ERICA assessment tool was employed to provide an assessment of the potential doses to biota’s growing in agro forest E. oblongus appears to be much prone to radiation absorption from the dose risk point of view. The annual effective dose (AED) due to ingestion of these radionuclides in E. roxburghiana was also estimated, and was found to be lower than the world average.

  • Influence of duration of storage at room temperature, pre-sowing seed
           treatment and fruit colour harvest index on germination and seedling
           growth of Jatropha curcas L.
    • Authors: T. Nyamayevu; A. B. Mashingaidze
      Pages: 1221 - 1235
      Abstract: ABSTRACT Jatropha curcas L. is being promoted by governments for greening marginal areas for rural development and biodiesel production in sub-Saharan Africa, however large gaps in knowledge on its agronomy and yield potential exist. The effect of duration of storage at room temperature, pre-sowing seed treatment of Jatropha seed and fruit colour harvest index on germination and seedling growth parameters was investigated. There was a significant negative correlation between the duration of storage of Jatropha seed and seed oil content (P < 0.001, r = −0.99), viability (P < 0.01, r = −0.93), percent germination (P < 0.05, r = −0.90) and germination index (P < 0.05, r = −0.89). The relationship between duration of seed storage and seed oil content and seed germination parameters was best described by quadratic and exponential functions which showed rapid declines in seed oil content and germination parameters in the first 3 years of storage and a slower decline between 3 and 8 years of storage. There was a significant negative correlation between duration of storage and seedling height (P < 0.01, r = −0.97), stem diameter (P < 0.01, r = −0.93) and dry weight (P < 0.05, r = 0.91) that was best described by quadratic functions. Seed oil content was significantly and positively correlated to seed viability (P < 0.01, r = 0.96), germination per cent (P < 0.01, r = 0.94) and germination index (P < 0.01, r = 0.93). The relationship between seed oil content and seed germination parameters was best described by exponential functions which showed an exponential increase in seed germination parameters as oil content increased above 30% and smaller increases below 30% oil content. Progressive peroxidation of lipids as seed aged explains the loss of oil from the seed. Peroxidation of lipids produced highly reactive radicals that damaged membranes and proteins reducing seed germination and seedling growth parameters as seed aged. Pre-sowing seed treatments (seed soaking and scarification) produced marginal gains in germination and seedling growth parameters in Jatropha seed stored for 3 months to 8 years. Seeds harvested at the yellow fruit maturity index, 60 days after anthesis (DAA), showed the highest seed germination percent while seed harvested at the black fruit maturity index, 75 DAA, had the highest oil content. Harvesting of Jatropha seed for oil expression is therefore recommended at the black maturity index while harvesting for seed is recommended at the yellow maturity stage. The results of this study indicate that Jatropha seed should be stored for as short a period of time as possible to maximize seed germination, seedling growth and oil yield.

  • Growth and survival of the Mayan palm Chamaedorea hooperiana in two
           villages of Los Tuxtlas Biosphere Reserve, Veracruz, Mexico: a comparison
           between primary and secondary forests
    • Authors: J. A. García-Pérez; I. Barois; E. Alarcón-Gutiérrez
      Pages: 1237 - 1252
      Abstract: In the Los Tuxtlas Biosphere Reserve, Veracruz, México, managers and farmers of two communities have promoted the cultivation of Chamaedorea hooperiana amid primary forest (PF) on the assumption that this would provide viable economic income while contributing to forest sustainability. The aim of this study was to test whether or not C. hooperiana is able to grow in PF without canopy management, and to compare its growth pattern to the one observed in secondary forest (SF) (acahual) managed by farmers. The performance of C. hooperiana was evaluated for nearly a thousand days in patches of forest from two communal lands dedicated to palm extraction. The results indicate that the palms grew four to five times faster in the SF than in the PF, although the number of leaves was only about one-and-a-half times greater. Also, a different growth pattern was detected at each site in terms of plant height and length of leaves, i.e., allometric growth was negative in the PF (the length of leaves increased more slowly than the height of the palms) and positive in the SF (length of leaves increased faster than the height of the palms). It was concluded that although C. hooperiana may be defined as a shade-tolerant plant species growing best under intermediate light, seedlings will not grow under a closed canopy of PF, except at those gaps with enough light. Growing the Mayan palm under SF opens up the possibility of rehabilitating deforested areas.

      Abstract: The aim of this paper is to analyze the impact of a set of interventions related to on-farm/in situ conservation and use of fruit species (cultivated and wild) on farmers’ livelihoods and species diversity in Central Asia. Specifically, a difference-in-differences propensity score matching is used to evaluate the outcome of a development research program in Uzbekistan between 2005 and 2010. Species crop diversity maintained by farmers before and after the project increased as a result of the interventions, showing the efficacy of the interventions promoted by the projects in terms of conservation. Furthermore, innovations provided by the program increased both household propensity of marketing and self-consumption of target fruit. However, the program’s interventions did not seem to impact significantly any of the indicators related to household livelihoods. The short time elapsed between the end of the project and the impact assessment may be too brief to capture any observable impact on livelihoods.

  • Photosynthetic characteristics and simulation of annual leaf carbon gains
           of hybrid poplar ( Populus nigra L. × P. maximowiczii Henry) and black
           locust ( Robinia pseudoacacia L.) in a temperate agroforestry system

      Pages: 1267 - 1286
      Abstract: A leaf net photosynthesis model is presented driven by light and modulated by temperature and air humidity. From this the seasonal variation of CO2 uptake and release could be modelled to estimate the annual carbon fluxes of sun and shade leaves. In fully expanded leaves light is the major factor determining daily carbon balances, and highest observed daily carbon gains in sun leaves amounted to 748.9 mmol CO2 m−2 day−1 in poplar and to 536.3 mmol CO2 m−2 day−1 in black locust, while the annual carbon gains amounted to 46,824 mol CO2 m−2 in black locust and 66,803 mol CO2 m−2 in hybrid poplar. Results obtained via gas exchange measurements and from the leaf model clearly indicate a potentially better growth performance of the poplar compared to black locust on the investigated site. The presented photosynthesis model provides a good and realistic estimation for seasonal carbon balances on the leaf level for both species.

  • The economic potential of Gevuina avellana in New Zealand planted
           forests
    • Authors: Lania Holt; Glen Murphy
      Pages: 1287 - 1300
      Abstract: Gevuina avellana (gevuina) is a South American tree that produces edible nuts. This study conceptualizes the transformation of a planted radiata forest into an agroforestry system that integrates radiata and gevuina trees to produce timber and Non Timber Forest Products (NTFPs). This study assesses the economic potential of growing gevuina nuts in a New Zealand planted forest case study. Findings suggest that planted forests offer the potential for commercial scale using land use opportunities created around road infrastructure, and in pocket areas connected by roads. The economic returns determined in this study were significant, even in small areas. The key to realising this potential will be in the identification and use of the production strategies to handle the complex system.

  • Santalum molecular biology: molecular markers for genetic diversity,
           phylogenetics and taxonomy, and genetic transformation

      Pages: 1301 - 1315
      Abstract: Species of the Santalum genus are well known for their fragrant hardwood, which has great value in medicinal, pharmaceutical and cosmetic industries. Sandalwood oil is derived from the heartwood of Santalum sp. and contains α-, β- and epi-β-santalols, which are responsible for its pleasant fragrance. Oil content can vary from species to species. Pressure on natural populations due to habitat loss, legal and illegal harvesting and disease is increasing. This paper highlights the development of molecular markers for the refinement of phylogenetic studies, identification of various Santalum and adulterant species, assessment of genetic diversity, genetic differentiation, clonality and management units within species, and for marker-assisted breeding. The identification of quantitative trait loci for sandal spike disease and for other traits such as specific rare secondary metabolites in the essential oil and related to its fragrance, would also benefit from molecular advances. RNA sequence analyses have already identified changes in gene expression and metabolic pathways in developing Santalum album L. haustoria.

  • Home garden agrobiodiversity in cultural landscapes in the tropical
           lowlands of Tabasco, México
    • Authors: Alejandro Alcudia-Aguilar; Hans van der Wal; Juan Suárez-Sánchez; Pablo Martínez-Zurimendi; María Mercedes Castillo-Uzcanga
      Pages: 1329 - 1339
      Abstract: We studied whether agrobiodiversity in home gardens reflects the cultural landscapes that embed them. We compared floristic composition, biomass and cover of trees in home gardens between the cultural landscapes on mountain slopes (MSL), small hills (SHL), and floodplains (FPL) in a segment of the Grijalva–Usumacinta watershed in the tropical lowlands of Tabasco, Mexico. We characterized the cultural landscapes based on information obtained through questionnaires, identified species and measured tree height and diameter at breast height in random samples of home gardens from two localities in each case. The cultural landscapes showed distinct land use combinations: MSL comprised subsistence agriculture, pasturelands and forests; SHL pasturelands, some secondary vegetation and industrial agriculture fields; and FPL mainly industrial agriculture fields and pasturelands. Total species richness was greater in MSL than in SHL and FPL. Mean species richness was greater in MSL and SHL (22.4 and 15.8 respectively) than in FPL (7.2), as was the mean number of individuals per home garden (98.2, 94.1 and 20.4. Dominant species in home gardens in FPL and SHL included particular secondary species for each landscape, whereas single or double occurrences of mature forest species were distinctive of home gardens in MSL. Mean biomass was greater in MSL than in SHL and FPL (37.1, 28.2 and 23.7 Mg C ha−1), as was tree cover (1.06, 0.95 and 0.76 m2/m2). We conclude that agrobiodiversity varies considerably among cultural landscapes and recommend the design of specific policies to enhance its conservation in each of them.

      Abstract: To address the growing global demand for cocoa, sustainable intensification of its production in West Africa is considered crucial. This paper analyzes the determinants of cocoa productivity and profitability by smallholder farmers in Ghana to provide insights into challenges for future cocoa farming, which will guide the formulation and prioritization of tailored policies to address them. A four-stage sampling technique was used to select a total of 731 cocoa farmers from various districts in all six cocoa growing regions in Ghana. Selected farmers were interviewed using a semi-structured questionnaire. The results show that cocoa productivity and profitability was very low with an average of 234 kg ha−1 and Gh¢ 568 (ca. US$ 150) per ha, respectively. Farm management practices, namely control of capsid and black pod disease, fertilizer application and pruning, significantly (p < 0.05) influenced cocoa productivity. Capsid control and fertilizer application showed the highest impact on productivity. Farm size, however, had a negative impact, which implies that increase in farm size results in decreased smallholder cocoa productivity. Farmers should be encouraged to sustainably intensify farm management through controlling black pod disease and capsids, regular pruning and efficient application of fertilizer rather than focusing on excessive land expansion, which eventually hampers productivity and biodiversity.

      Pages: 1387 - 1396
      Abstract: Post-adoption studies are relatively uncommon in the agroforestry literature. Thus little is known about progress and permanence following adoption. To better understand the relationship between agroforestry implementation and community development, seventy-seven practitioners in Cameroon with three or more years of experience were surveyed about the relationships between agroforestry and community development. Hypotheses were that they have observed differences in the association between agroforestry and community capitals. They were also surveyed about their satisfaction with agroforestry. Hypotheses were that satisfaction is high and negatively skewed when compared to community capitals measurements. Game play was used to collect responses. Friedman’s two-way non-parametric statistic was used to test for inter-item differences within the community capitals and satisfaction response sets. Shapiro–Wilk statistic was used to test for normality in both response sets and a bootstrap procedure and t-tests were used to test for differences in data skewness and kurtosis. Natural capital scored highest but did not differ significantly from built, human, and social capitals. Financial capital was significantly lower than natural capital, but not built, human, or social capitals. Political and cultural capitals were significantly lower compared to all others. Satisfaction was significantly higher when compared to community capitals, but the data were also negatively skewed suggesting capitals are a more representative and useful metric for researchers and technical assistance professionals focused on long-term practitioner support.

      Abstract: The many benefits of agroforestry are well-documented, from ecological functions such as biodiversity conservation and water quality improvement, to cultural functions including aesthetic value. In North American agroforestry, however, little emphasis has been placed on production capacity of the woody plants themselves, taking into account their ability to transform portions of the landscape from annual monoculture systems to diversified perennial systems capable of producing fruits, nuts, and timber products. In this paper, we introduce the concept of multifunctional woody polycultures (MWPs) and consider the design of long-term experimental trials for supporting research on agroforestry emphasizing tree crops. Critical aspects of long-term agroforestry experiments are summarized, and two existing well-documented research sites are presented as case studies. A new long-term agroforestry trial at the University of Illinois, “Agroforestry for Food,” is introduced as an experiment designed to test the performance of increasingly complex woody plant combinations in an alley cropping system with productive tree crops. This trial intends to address important themes of food security, climate change, multifunctionality, and applied solutions. The challenges of establishing, maintaining, and funding long-term agroforestry research trials are discussed.

  • Socioeconomic and productive characteristics of dual purpose farms based
           on agrosilvopastoral systems in subtropical highlands of central Mexico
    • Authors: Benito Albarrán-Portillo; Anastacio García-Martínez; Arturo Ortiz-Rodea; Rolando Rojo-Rubio; José Fernando Vázquez-Armijo; Carlos Manuel Arriaga-Jordán
      Abstract: Agrosilvopastoral systems that integrate crops, pastures, trees and shrubs are seen as a way forward to meet future needs for food, feed, fuel, and other products, as well as for providing environmental and social benefits. Cattle production systems in the tropical and subtropical areas of Mexico have a dual-purpose (milk and beef) objective in agrosilvopastoral systems that need to improve the production of goods, as well as non-productive outputs like environmental services, enhancing their sustainability. The aim of this study was to characterise the socioeconomic, and productive characteristics of dual purpose farms based on agrosilvopastoral systems (ASPS), in a subtropical region in the southern highlands of central Mexico, to contribute in the understanding of how these ASPS operate and their differences. Forty-seven farmers answered a semi-structured questionnaire to identify aspects of farm management, structure, and land use; as well as technical and economic aspects. Information was analysed using factorial analysis of principal components, in order to reduce information, and subsequently cluster analysis that included nine variables resulting into four groups of farms differentiated by structure, size, management and productive orientation. Productive orientation of the farms was from the activity from which farms obtained most of their incomes. The four groups were beef production oriented (BPO) 46.81%, milk production oriented (MPO) 23.40%, pure breed weaned calves (PBWC) 17.02%, and traditional dual-purpose (TDP) 12.77%. Characterization of agrosilvopastoral farms identified main differences and characteristics, as well as the presence and use of trees and shrubs by farmers and cattle.

  • Performance of two valuable species, Pinus pseudostrobus and Eysenhardtia
           polystachya, in a low fertility soil mediated by mycorrhizal fungi and
           fertilization
    • Authors: Mariela Gómez-Romero; Roberto Lindig-Cisneros; Javier Villegas
      Abstract: Interspecific relationships are fundamental to maintain ecological processes, and are particularly important for the recovery of plant cover in severely degraded sites. An experiment was set up to evaluate pairs of Pinus pseudostrobus–Eysenhardtia polystachya plants, the first inoculated with Pisolithus tinctorius and the second inoculated with P. tinctorius and/or Rhizophagus intraradices, plus inoculation controls, and phosphorus fertilization. Growth and biomass were measured as response variables. For the pines, only height and number of branches responded to factors directly applied to the tree: fertilization and inoculation with Pisolithus tinctorius. However, these variables also responded to inoculation of the legume with Rhizophagus intraradices, implying an indirect effect on the pine plant. Furthermore, this indirect effect was significant for pine biomass accumulation. Fertilization had a positive and significant effect for the legume plants increasing the values for almost all of the variables (apart from branch length) but for some variables the simultaneous presence of both mycorrhizal fungi was detrimental. Different combinations of fertilization and inoculation benefit growth of the pines and the legumes. When environmental restoration of production systems is considered, either conditions favoring the legume can be achieved (if protection of the soil in the short-term is desirable), or conditions favoring the pines can be implemented (if favoring the tree species is preferable).

  • Eco-benefits coupling of agroforestry and soil and water conservation
           under KRD environment: frontier theories and outlook
    • Authors: Qinglin Wu; Hong Liang; Kangning Xiong; Rui Li
      Abstract: Karst rocky desertification (KRD) has become the most serious Eco-environmental problem in karst areas, seriously threatening the livelihood of local people and leading to their poverty. Modern agroforestry practices not only maximize the social and economic but also great ecological benefits, suggesting a possible control to KRD. Through reviewing the existing studies in relation to agroforestry and soil and water conservation, this paper systematically investigates into the ecological benefits from agroforestry, including the increase of carbon sequestration and soil fertility as well as soil microfauna, the conservation of soil and water, the mitigation of soil pollution and the reduction of greenhouse gas emission. It founds, across KRD areas, that there exists coupling ecological benefits when practicing agroforestry and conserving soil and water. Based on this finding, this paper further suggests the corresponding key technologies that welcome more studies: preventing soil leakage from underground; effectively utilizing water from above-and-below ground; developing highly-efficient and value-added water-saving industries; forming forest-grain-grass stereo optimal configuration. The aim is to ensure a favorable Eco-environment while at the same time to develop beneficial ecological industries across KRD areas.

  • An exploratory analysis of US consumer preferences for North American
           pawpaw
    • Authors: Zhen Cai; Michael Gold; Robert Brannan
      Abstract: The North American pawpaw (Asimina triloba (L.) Dunal) is a high-value native specialty fruit crop that offers multiple opportunities for commercial value-added products. A survey was conducted to obtain a better understanding of consumer preferences for pawpaws as fresh and value-added food products. The survey was distributed to 524 individuals who were members of the North American Pawpaw Growers Association, attendees of the 2016 International Pawpaw Conference at Frankfurt, Kentucky, and participants at the 2017 Ohio Pawpaw Festival, Albany, Ohio. Respondents were asked to self-identify their positions (consumers or producers) in the pawpaw market. Those who self-identified as consumers were asked to take the survey. A total of 192 responses were collected. Survey results indicated that the majority of the respondents consume fresh or value-added pawpaw products at least once a year. They reported strong preferences for the flavor and texture of fresh pawpaws. Price, origin, and type of production process had statistically significant impacts on consumers’ purchase preferences. The characteristic that most influenced demand was local production—consumers were willing to pay a premium of $5.20/kg for locally produced pawpaws compared to pawpaws of unknown region of origin. Consumers also preferred certified organic and pesticide-free pawpaws to fruit produced using chemical fertilizers, pesticides, and herbicides. The average price premiums consumers were willing to pay for certified organic and pesticide-free fruits were $4.19 and $3.28/kg, respectively. Providing information about the region of origin, organic and pesticide-free production processes can potentially increase consumer demand for pawpaws and their share of the fresh and value-added fruit market.

  • Potential contribution of plants bioactive in ruminant productive
           performance and their impact on gastrointestinal parasites elimination
    • Authors: Mohamed M. Zeineldin; Ahmed A. Sabek; Radwa A. Barakat; Mona M. M. Y. Elghandour; Abdelfattah Z. M. Salem; Roberto Montes de Oca Jiménez
      Abstract: The worldwide emergence of anthelmintic resistance against gastrointestinal (GIT) parasites prompts investigation towards sustainable alternative approaches. Accordingly, several approaches have been endeavored to control GIT parasites and increase economic values of livestock production systems. Current scientific evidence implies that there is substantial capability to use the plant bioactive compounds to enhance animal’s health and promote their productivity. Despite the great efforts in management, GIT parasites remain the main cause of mortality and weight gain–loss in ruminant industry. Recently, there is worldwide interest in exploiting plants bioactive and their secondary constituents as substitutes to anthelmintic treatment. However, we still necessitate to collect further data about their concentrations, sources, and composition, not only that but also understand their potential beneficial and detrimental impacts in livestock production. Simultaneously, our review discusses the research efforts towards the development of plants bioactive and their impact on GIT parasites elimination in ruminants.
