  • The aflatoxin occurrence of food commodities in Sri Lanka: an overview of
           prevalence, detection and decontamination techniques

    • Abstract: Aflatoxins has been a topic of discussion in Sri Lanka over the recent past, due to many reported cases of aflatoxin prevalence in several food commodities. Most food spoilage and deterioration are attributed to fungal and mold attacks, whereas aflatoxins are a secondary metabolite produced by the fungal genus Aspergillus that dominates the food supply chain. Primarily four types of Aflatoxins; AFB1, AFG1, AFB2, and AFG2 were reported in food contamination and two types; AFM1 and AFM2 were reported to contaminate feedstuff and thereby present in milk and dairy products. Aflatoxins were given focused attention of this caliber due to their extreme toxicity which causes several diseases including aflatoxicosis in humans, livestock and domestic animals globally. The occurrence of these aflatoxins and a few outbreaks were reported in several food types worldwide including Vegetable oils, Nuts and Seeds, Cereals and Dairy products. In Sri Lanka, such occurrences have been reported since the early 1980s, to date. Considering the severity of toxicity, there have been several legislations and regulations introduced both locally and internationally. The Codex Alimentarius, FDA, and EU Legislation are some international regulatory bodies, while Sri Lanka has the regulations defined by the SLSI. According to the studies conducted in recent years, the reported occurrences of Aflatoxins in food and feedstuff were significantly reduced to the previous studies which could result from proper housekeeping practices, proper storage and adopting proper decontamination techniques. However, controlling and decontamination of the aflatoxins in food is a necessity to stay within the regulated maximum permissible levels by the regulatory bodies. Controlling Aflatoxin contamination may be either pre-harvest, which involves good agricultural practices, fungicide application, pest control and novel biocontrol techniques such as introducing nontoxigenic aspergillus strains to the crop produce for competing with toxigenic strains, or Post-harvest such as physical, chemical and biological decontamination methods.

  • Physical barriers for diamondback moth management in cabbage of up country
           region in Sri Lanka

    • Abstract: Central highland is one of the major Cabbage (Brassica oleraca) producing regions in Sri Lanka. Diamondback Moth (DBM) (Plutella xylostella) is one of the key pests of cabbage that causes a significant yield loss. Farmers heavily use agro-chemicals to control DBM while ignoring alternative non-chemical eco-friendly pest management strategies. Therefore, attempts were made to evaluate the combined effectiveness of three physical pest management strategies to suppress the DBM population in cabbage. Field experiments were carried out at the Agriculture Research Station, Seetha-Eliya during the 2020 and 2021 Yala cropping seasons. A blinking light, sprinkler irrigation and insect-proof net were selected as physical DBM control measures. The combined effects of these strategies were evaluated in comparison with recommended insecticides. The result revealed that the combined effect of blinking lights, sprinkler irrigation and insect-proof net significantly reduced DBM larval infestation and damage severity of cabbage with effective yield performance. Blinking lights and insect-proof net were found to be alternative strategies to manage DMB larval infestation. Routine application of insecticides for DBM control in cabbage could successfully be replaced with these physical barriers. It was concluded that a package for DBM management in cabbage comprising of these measures could be introduced for cabbage farmers in the up-country region in Sri Lanka.

  • Morphological characterization and yield performance of exotic okra
           (Abelmoschus esculentus) genotypes at Sylhet Sadar, Bangladesh

    • Abstract: Okra (Abelmoschus esculentus) is one of the most important green fruit vegetables in Bangladesh and is grown in all parts of the country. However, its production varies in the different agroecological regions. Thus, the present study was conducted in the Sadar Sylhent region, Bangladesh to assess the exotic okra genotype (s) based on morphological, reproductive and yield attributes. A total of 10 Japanese okra genotypes (JO-1 to JO-10) were comparatively evaluated with the BARI Dherosh-1 (control) in a randomized complete nlock design in triplicates. All the morphological features viz. stem colour, leaf, vein, petiole, pedicel, epicalyx, speal and fruits were demonstrated almost similar in all the studied genotypes except JO-5. Considering reproductive traits, results showed the significant variations amid the studies genotypes and an individual genotype performed better in some unique traits. The highest number of flowers (17), fruit setting (84.56%) and fruits per plant (14.1) was obtaines in the genotype JO-7 while JO-3 possessed maximum ovary length (1.5cm), fruit weight (23.86g) which in turn produced the heaviest fruit. The highest yield was recorded in the genotype JO-7 yielded the highest fruit yield (14.08 t ha-1) followed by JO-9 (11.92 t ha-1) and JO-3 (11.22 t ha-1) while the lowest yield was recorded in JO-5 (2.47 t ha-1). In conclusion, the genotypes JO-9 and JO-3 may be promising lines for cultivating exotic okra in the Sylhet region, Bangladesh. Published on 2022-10-04 00:00:00
       
  • Genotype by environment interaction (GEI) of maize varieties resistant to
           maize lethal necrosis for mid altitudes of Rwanda

    • Abstract: Maize is a leading crop in Rwandan agriculture, but its production is threatened by the outbreaks of Maize Lethal Necrosis (MLN) virus disease. The establishment of MLN artificial inoculation facility in the region where Rwanda is located has facilitated the developing MLN resistant maize genotypes. The objective of this study was to identify maize MLN resistant varieties that are high yielding and stable across environments, and to integrate them with other disease management strategies in Rwanda. Forty-one maize varieties were screened through MLN artificial inoculation facility in Naivasha, Kenya. Then, 24 of them were evaluated under natural inoculation in Karama research station, Rwanda. Twelve potential maize varieties were investigated for genotype by environment interaction in four sites at mid-altitudes in Rwanda, including Cyabayaga Karama and Bugarama, over two consecutive seasons. The study identified three maize MLN moderately resistant varieties; RHM1402, RHM1407, and RHM1409 that are high yielding and stable across environments. MLN was found to increase the incidence of ear rot, hence, raising the risks of infection with harmful mycotoxins such as aflatoxins. In order to manage the MLN disease in Rwanda, it has been advocated that the identified varieties be made available to farmers and integrated with other methods of control.

  • Effect of feeding two types of local fishmeal rations on broiler
           performance

    • Abstract:   Current study was conducted to find out the possibility of using two types of local fish meals as animal protein sources in broiler rations. Ninety-nine unsexed day-old broiler chicks of Hubbard Flex strain were randomly allocated to three dietary treatments each having three replicates of eleven chicks per replicate in a completely randomized design (CRD). Diets 1 and 2 contained 2.5 % of locally produced Heteropneustes fossilis (Stinging catfish) fish meal and Spilotichthys pictus (painted sweetlips) fish meal, respectively while diet 3 was a commercial feed containing imported fish meal. During the first 14 days, all the chicks were fed with a commercial broiler starter ration. From day 15 until 42 days, birds were fed with experimental diets ad-libitum. Feed intake and weight gain per bird in g/day for the dietary treatments diet 1, diet 2 and diet 3 were 89.00±2.54, 92.95±2.64, 100.56±4.66 and 50.34±1.48, 53.85±2.53 and 60.39±2.99, respectively. Diets with local fish meal recorded lower feed intake and weight gain compared to diet 3 (P<0.01). Higher feed intake and weight gain were recorded for diet 2 than for diet 1. Diet 2 recorded the highest profit per kg of carcass weight (Rs 103.37±2.80) (P< 0.02) while the differences between diet1 (Rs 93.78±3.00) and diet 3 (Rs 93.69±1.89) were not significant. As far as the cost of production per kg of carcass weight is considered diet 2 recorded the least cost (Rs 326.64 ± 2.79) (P< 0.01) while the differences between diet 1 (Rs 335.28±4.10) and diet 3 (Rs 336.50 ± 1.89 were not significant. Diet 2 was the most profitable treatment. It could be concluded that poultry feed formulated with 2.5% painted sweetlips fish meal or stinging catfish fish meal instead of commercial feed with the imported fish meal can be fed to broilers successfully and can make more profit. Painted sweetlips fish meal was better than stinging catfish fish meal in terms of broiler performance and profits. In addition, this will pave the way to make use of the trash fish which are mostly wasted otherwise and open up employment opportunities for the people involved in the value chain of broiler feed or broiler industry.

  • Effect of addition of Withania somnifera (Ashwagandha) root powder on
           selected properties of cow milk

    • Abstract: Withania somnifera (Ashwagandha) is an important tropical herb with proven health benefits which has an enormous potential to be used in functional food applications. The present study aimed to find out the effect of the addition of W. somnifera root powder (WSRP) on the compositional, physicochemical, physical, functional and sensory properties of cow milk. Skimmed and standardized (3% fat) milk were separately fortified with WSRP at the rate of 0, 0.5, 1.0, 1.5 and 2 percent levels, well mixed and pasteurized (63°C for 30 min) ending up in 10 treatments. 2 x 5 (milk type x WSRP level) factorial arrangement of treatments in a completely randomized design was used with 3 replicates and SPSS (ver. 20) was used for the data analysis. Significant (p<0.05) reduction of rennet coagulation time (RCT) was observed with increasing WSRP percentage irrespective of the type of milk. Standardized milk had significantly (p<0.05) lower RCT than skimmed milk. Instrumental colour values were significantly (p<0.05) affected by the added WSRP in both milk types while fermentation characteristics were not affected. Sensory scores were decreased with increasing levels of WSRP in both milk types due mainly to the sedimentation effect. From the above results, it is concluded that a possibility exists to fortify milk with WSRP and produce functional fermented dairy products such as cheese and yoghurt. Nevertheless, studies are needed with other forms of W. somnifera such as root powder extract to reduce the impact of sedimentation. Published on 2022-10-04 00:00:00
       
  • Fisher relevant wellbeing indicators of migrant fishers in Sri Lanka

    • Abstract: Wellbeing is a person-centered and community-specific concept thus unique for the considered community. Identification of wellbeing priorities is a pre-requisite for any development programs and policies to uplift the living standard of the populace. This paper explores gendered wellbeing indicators of small-scale migrant fishers in Negombo and Chilaw in the West coast, who are migrating to Mannar, Sri Lanka. Three-dimensional wellbeing approach was adopted to assess; material, relational, and subjective dimensions of wellbeing, considering objective and subjective aspects together with relationships. Mixed method approach was employed to glean data administering a questionnaire survey (n=142) and in-depth interviews (n= 15). Ranked wellbeing factors were analysed using weighted frequencies. Remarkably 14 out of 25 factors belong to material wellbeing; six relational; and five are subjective. Most of these material wellbeing factors (8/14) namely financial stability, sustainable fishing methods, lower operational costs are livelihood-related. Being a collective and community-based occupation, fishing households value social cohesion and collaboration within their communities in relation to relational wellbeing. Women perceived access to sea (weighted mean (wm) 0.4), children’s education (wm= 0.32), and children’s future (wm= 0.48) than fishermen (0.16, 0.24, and 0.27 respectively). Despite fishermen and women value family relationships (wm = 0.82 and 0.88) and peaceful environment for fishing (wm = 0.38 and 0.27) as important relational wellbeing factors, fishermen also value good relationships within their own society (wm= 0.17) and harmony with local fishers at the migratory site (wm= 0.17). Religious activities, a subjective wellbeing factor has been valued by women (25%) than men (7%). Thus, most of the wellbeing indicators are occupation-specific and gendered. The 4Cs-catch, community, children and church have been recognized as fisher-relevant gender-responsive indicators for migrant fishers in the west coast, Sri Lanka.

  • Anther culture performances of selected Indica rice varieties in Sri
           Lanka: ability of callus induction and plant regeneration

    • Abstract: Doubled-haploid plant production through anther culture provides an efficient and appropriate system for rapid production of homozygous lines. Various culture conditions influence callus induction and plant regeneration efficiency. In this study, the optimization of media requirements and culture conditions for high-frequency callus induction and plant regeneration for selected indica rice varieties were evaluated using improved anther culture media. Panicles of ten selected rice cultivars (Bg 358, Bg 379-2, Bw 361, At 362, Bw, 364, Bw267-3, Bw 272-6b, At 306, Bg 357 and Kahata wee) were cold pre-treated at 10ºC for 7-10 days. After that anthers were cultured in agar solidified N6 and L8 media where hormonal combinations were modified. Calli were transferred to three different Murasinge and Skoog media for plant regeneration. Green and Albino shoots were observed. Best callus induction frequencies (6.9-11.1%) were acquired in the L8 medium containing 6% (w/v) maltose, over the N6 (3.6—5.7%) medium. Highly responsive genotypes for callus initiation were AT362, BG 379-2, BW 267-3 and AT 306. BG357 and BW 364 were the least responsive genotypes. The best callus induction frequency of 11.1% was observed in the L8 medium supplemented with 2.0mgl-1 2, 4-D and 0.5mgl-1Kinetin (KN) for AT 362. Maximum green plant regeneration could be observed in Kahata wee (29.2%) and AT362 (18.27%) varieties in MS media supplemented with 2mg/l BAP, 1mg/l NAA and 0.5mg/l KN. After 7-10days of callus initiation, they were transferred to MS medium to regenerate plants. Plant regeneration was observed after two weeks after the transfer. This information could be used in the development of homozygous plants with high yields and good grain quality from the best hybrid varieties. Published on 2022-10-04 00:00:00
       
  • Effect of foliar application of red large onion (Allium cepa L.) peel
           solution on growth and yield of cowpea (Vigna unguiculata L. WALP)

    • Abstract: Cowpea (Vigna unguiculata L. Walp.) is a significant food and grain legume in the semi-arid tropics. Red onion peels are used to make organic potassium-rich fertilizer for growing plants. The effect of foliar application of red onion peel solutions on growth and yield of cowpea cv dhawala were studied in a pot experiment at the home garden, Mailapitiya, Kandy, Sri Lanka, from May to September 2021. This study was designed in a randomized complete block design with six treatments. They were as follows: T1 – control (distilled water), T2 – 20% onion peel solution, T3 – 40% onion peel solution, T4 – 60% onion peel solution, T5 – 80% onion peel solution, T6 – 100% onion peel solution applied at two weeks interval. Foliar application of onion peel solutions led to significant (P
       
  • Management of host-parasite interactions between Bambara groundnut and
           Fusarium wilt inducer

    • Abstract: Bambara groundnut (Vigna subterranea (L.) Verdc) is an excellent source of human and animal foodstuff and pharmaceutical resources but its production is hampered by fungi diseases. Synthetic pesticides, botanicals and bio-control sub-trials were conducted in vitro to control Fusarium oxysporum f.sp. voandzeia. The sub-trials were each set up using completely randomized design with three replications. Data were collected on radius of the growth and area covered by the colonies. Percentage inhibition of F. oxysporium (at 120 hours after inoculation (HAI)) using Trichoderma isolates ranged from 16 – 87%. Significantly (P ≤ 0.05) less area of medium was covered by the pathogen due to presence of T. harzianum NSBM, T. harzianum AIM16, T. harzianum AIM5, T. harzianum BGMP, T. virens BGMZ2, T. harzianum ZXMZ isolates and check compared to the control. Percentage inhibition of F. oxysporium (at 144 HAI) using Mancozeb and Copper(I)oxide+Metalaxyl ranged from 26 – 100% and both pesticides inhibited Fusarium significantly (P ≤ 0.05) more than the control.
