  • Development of Drip Flow Technique Hydroponic in Growing Cucumber

    • Abstract: Hydroponics is a new branch and aspect of food crop growing that in recent years made its mark in developing country such as Nigeria. Although, its adoption has not been too encouraging. This research work aimed at developing a drip technique system of hydroponics in determination of the agronomic parameters of cucumber by comparing the yield, water and nutrient efficiency, its consumptive use and proximate and mineral composition of cucumber. The experiment was carried out in a complete randomized design with three treatments; organic substrate (coconut coir), inorganic substrate (styrofoam) and soil. These treatments were replicated five times. The vegetative growth (agronomic parameters), yield, water and nutrient, proximate and mineral composition were measured. The result showed the consumptive use as 0.0044 m3 per day and 0.3212 m3 as the water and nutrient use efficiency. The result also showed that organic substrate gave the highest mean plant height of 736.66 mm, highest mean stem diameter of 5.79 mm and highest mean number of leaves of 9.75 while inorganic substrate gave highest mean plant height, mean stem diameter and mean number of leaves as 336.28 mm, 4.95 mm and 7.68 respectively. Also, the highest result of control (soil) gave 301.23 mm, 5.47 mm and 7.06 for the mean plant height, stem diameter and number of leaves respectively. The yield of cucumber as compared with the different growing media showed that there is no significant difference between the growing media (Fcrit> Fcal) unless for the plant height and number of flowers having Fcrit less than Fcal. From these results, it is advisable that drip technique system should be embraced by farmers whose primary aim of farming is for leafy vegetables and non-leafy vegetables as seen in the increase in stem diameter and plant height in the organic substrate.

  • Sustainable Agroforestry Crop Rotation System for the Tropics: A
           Theoretical Exposition

    • Abstract: Population pressure is the key reason that has been reducing the duration of fallow in shifting cultivation. In many places, it has changed to bush fallow and subsequently is going towards the need to use available arable lands continuously. As a result, soil productivity is declining since long fallow is required for its regeneration after land is planted for a few years. An agroforestry tree crop/arable crop rotation system was proposed to mimic the natural fallow system and improve nutrient recycling through litter drops, which will improve soil organic matter. As soil organic matter improves the soil structure in addition to the ability of the soil to retain nutrients and water, the land becomes suitable for continuous crop production with appropriate fertilization regimes. The proposed tree crop/arable crop rotation will therefore result in continuous generation of income from harvestable produce in the rotation system year in year out. The paper, equally elucidated on other benefits of rotating tree crops with arable crops on the same land towards achieving maximum land productivity and obtaining benefits from the land without subjecting the land to the traditional fallowing system. This intervention will reduce abject poverty (SDG1), reduce acute hunger (SDG2), promote sustainable economic activities and growth, increase employment and decent work (SDG8) and promote sustainable industrialization and foster innovation (SDG9). The paper also identified the challenges associated with this type of rotation system and proffered suggestions on how to ameliorate such challenges.

  • Evaluation of Post-weaning Efficiency in Nellore-Angus Crossbred Steers
           through Model Predicted Residual Consumption

    • Abstract: The objective of this work was to evaluate efficiency traits of Nellore-Angus crossbred steers (n = 349) on feed. Steers were fed a grain-based diet beginning at approximately 12 months of age for an average of 140 days. Contemporary groups were born in the fall or spring of 2003 through 2007 in full-sibling embryo transfer families or half-sibling families all sired by the same bulls. Individual intake was measured and weights were recorded to permit calculation of average daily gain. Residual feed intake (RFI) was estimated as the residual of models employing regressions on metabolic mid-test weight and ADG. An additional efficiency metric was also constructed and evaluated: model predicted residual consumption (MPRC). Mixed linear models were used to analyze daily dry matter intake, average daily gain (ADG), metabolic mid-test weight, RFI, and MPRC. Large positive associations of DMI with MPRC and RFI were identified along with low positive associations between metabolic mid-weight with ADG and MPRC. Genome wide association analysis revealed 5 regions associated with DMI, but none for the other traits analyzed. Residual feed intake values varied greatly between the contemporary group value and the overall value for the steers, showing the calculation’s dependency on the reference population. However, MPRC as based upon a standardized population, did not fluctuate. More selection phenotypes and strategies are needed for large-scale improvements in global beef cattle production sustainability. The stability of the MPRC metric could be beneficial for future feed efficiency research across multiple and diverse contemporary groups, and diverse production environments.

  • White Prairie Clover (Dalea candida Michx. ex Willd.) and Purple Prairie
           Clover (Dalea purpurea Vent.) in Binary Mixtures with Grass Species

    • Abstract: Native forage legumes may have potential for summer/fall grazing in semiarid prairie regions in mixture with grasses. The objective of this study was to evaluate two native clovers in binary mixtures with the introduced grasses when harvested in July and September to simulate late summer or fall stockpile forage. Eight binary clover–grass mixtures were seeded in a split-plot design with 4 replications at Swift Current, Saskatchewan, Canada. Mixtures included (i) AC Antelope white prairie clover (WPC)-Admiral meadow bromegrass (MBG), (ii) WPC-AC Success hybrid bromegrass (HBG), (iii) WPC-Bozoisky Russian wildrye (RWR), (iv) WPC-TomRWR, (v) AC Lamour purple prairie clover (PPC)-AdmiralMBG, (vi) PPC-AC SuccessHBG, (vii) PPC-BozoiskyRWR, and (viii) PPC-TomRWR. Clover establishment differed (p = 0.03) in July where WPC had 77.8% greater proportion in mixture than PPC, although both clovers increased (p < 0.001) in September to similar legume proportions, 663.2 and 876.1 kg/ha, respectively. Clovers with bromegrasses produced 41.9% more forage dry matter yield in summer than clovers with Russian wildryes (p < 0.001), though the latter mixtures had slightly better nutritive value (avg. 7.0% vs. 5.2% crude protein (CP). Clover–MBG exhibited higher (53.6%) in vitro organic matter digestibility (IVOMD) than Clover–HBG (51.2%) (p = 0.04). Purple prairie clover with grass or both clovers in mixture with bromegrasses, produced adequate forage biomass for summer and fall grazing, except clovers with Bozoisky RWR, while clovers with both RWR cultivars had acceptable forage nutritive value for summer in this semiarid prairie region.

  • Hay Nutritional Quality and Grassland Bird Nesting: Impact of Delaying
           First Hay Cut on Dairy and Beef Production in Ontario

    • Abstract: Perennial forage production exists in Ontario to support the livestock industry, but also provides nesting habitat for grassland birds such as the threatened Bobolink (Dolichonyx oryzivorus) and Eastern Meadowlark (Sturnella magna). Delaying hay harvest until July 15 or later allows most nestling birds to leave the nest, but the nutritional value of hay decreases substantially. This project estimated the nutritional and economic impact of delaying the first hay cut until after July 15 on beef and dairy production in Ontario, Canada. Forage crops were sampled across Ontario, analysis of nutritional value performed, and effects on production and economics modelled. 634 samples were collected over 13 weeks at 16 sites from May 21 to August 14 during 2014 and 2015. As expected, nutritional quality declined over the season. Crude protein decreased by 5.2%, total digestible nutrients by 7.7%, neutral detergent fibre digestibility (NDFd48) by 20.1%, while lignin increased by 3.5%, neutral detergent fibre by 13.1%, and acid detergent fibre by 9.9%. Estimated yearly milk production decreased 10.9 kg or C$7.87/dairy cow for each day of delay in harvest (2017 values). Estimated growth of backgrounding beef steers decreased 1.56 kg or C$5.49/head for each day of delay in harvest. This translated into lost revenue per acre for backgrounding steers of C$31 per acre and C$45 per acre for over wintering beef cows for a delay from mid-June to mid-July. Some agri-environmental incentives in Canada, US and Europe offset the reduced revenue due to lower quality forages. This analysis informs farmers about the cost of practices to benefit grassland birds and provides empirical data on how to structure stewardship incentives for these practices.

  • The Interplay between Informal and Formal Bylaws in Supporting Sustainable
           Crop Intensification in the Uganda Potato Production System

    • Abstract: The study assessed the interplay between informal and formal bylaws in supporting sustainable crop intensification, using a case of potato crop production in southwestern Uganda. The study used a descriptive case study design to understand and accurately describe the experiences of farmers in the potato crop subsector in the region. This involved mixed study approaches that ensured coded meaning of consistent responses to the study, and descriptive statistics facilitated sequential understanding of findings and how each related to one another in respective themes. The numerical scores enriched the findings by authenticating the qualitative outcomes of the study to minimize bias. The study used review of documents and literature; six Focus Group Discussions; and 22 Key Informant Interviews to gather diverse experiences of respondents patterns of responses, the main factors or categories, and key responses under every category. The Study found that the greatest informal bylaw was eucalyptus growing (50 percent), followed by permission to graze (18 percent), and control damping (18 percent). The widely represented formal bylaws had a comparatively lesser role in supporting SCI, although with greater emphasis on quality seed (22 percent). Formal bylaws were stronger at setting clear boundaries between users and resources (18 percent), users having procedures for making own rules (11 percent), regular monitoring of resources and users (15 percent), issue sanctions (16 percent), conflict resolution (15 percent), and coordinated activities (3 percent) than informal bylaws. The major benefits for operating as institution were the collective strategy for the market (26 percent), which was less to guarantee sustainable livelihoods for farmers. Individual farmers were driven by desire for faster benefits (13) and preferred following own rules (12 percent). There was more emphasis on market access, regardless of the nature of produce output (35 percent), whether the market worthy or not, and less on environment sustainability. The informal and formal bylaws are separate but united for a common purpose of intensifying potato crop production. Nonetheless, even when combined, they are not strong enough to support SCI. There is a need to strength bylaws on soil and water conservation, improved and quality seed potato and environment sustainability to support SCI, which provide the basis of greater markets and sustainable livelihoods.
