This study investigates the potential of superabsorbent materials like Super Absorbent Polymers (SAPs) and pumice to enhance water retention and agricultural productivity in Ngubreti in Mogotio Sub-County, Kenya, representing ASALs. Using a randomized design with different material ratios and a control group, the research analysed soil parameters and plant growth indicators. Incorporating superabsorbent materials increased soil porosity, reduced bulk density, and improved water retention. Bell pepper production notably increased by 53.4%, with the SAP Pumice Double Half (SPDH) treatment showing the highest yield. This research underscores superabsorbent materials' ability to enhance ASAL soil conditions and agricultural output, particularly SPDH treatment. Precise material concentration control and consideration of their impact on soil penetration rates are crucial for optimal results. The study contributes to sustainable agriculture in water-scarce regions, emphasizing soil management's role in crop productivity. Further research and region-specific experiments are needed for broader applicability. Farmers are advised to assess their soil characteristics and consider a recommended median soil-additives mixing ratio of 1:833. Long-term effectiveness warrants additional investigation","PeriodicalId":144021,"journal":{"name":"East African Journal of Agriculture and Biotechnology","volume":"45 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140671132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this purpose, a total of 36 equal-sexed New Zealand white rabbits aged 6 weeks ± 5 days old were randomly assigned into 4 treatments with 3 replicates each. The control animals (T0) received the basal diet without feed additive, while the 3 other groups T1, T2, and T3 respectively received diets 5, 10, and 15 g of ginger/kg of feed. Data was collected on feed intake, body weight gain, carcass indices and gut microbial load. Results revealed that the inclusion of ginger significantly (p<0.05) increased daily feed intake approximately by 16.02 g in T1 (5g ginger) compared to the control. The total feed intake followed the same trend. Daily weight gain increased approximately by 3.46g T3 (15g ginger). The feed conversion ratio was not significantly affected by dietary ginger inclusion. The addition of ginger did not significantly (p>0.05) affect the carcass characteristics of rabbits; However, a reduction was observed in abdominal fat content with approximately 0.81% in T3. Ginger powder in rabbits’ diets caused a decrease in the population of pathogenic microorganisms (gram-positive bacteria) but did not have any effects on total coliforms (gram-negative bacteria). It can therefore be concluded that ginger could be added to growing rabbits’ feed to improve live weight and reduce levels of gram-positive bacteria","PeriodicalId":144021,"journal":{"name":"East African Journal of Agriculture and Biotechnology","volume":"21 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140673643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studies indicate that greenhouse farmers face several challenges, sometimes leading to the abandonment of Greenhouses. The types and levels of severity of the challenges have not been adequately documented and acted upon on a context-specific basis, yet the demand for Greenhouse fresh produce is increasing, particularly in populated urban areas. This study identified and evaluated core challenges, available opportunities, and a concatenation of the challenges with productivity perceptions among Greenhouse farmers in Kericho County. A cross-sectional survey design drawing on data from 10% of Greenhouse farmers from each of the six Sub-counties was adopted for the study. Structured and unstructured interview schedules were administered to 59 sampled farmers and 16 Extension agents. The Henry Garret ranking method was used to analyse ranked data on challenges from farmers’ views and potential opportunities from Extension agents. A one-sample Wilcoxon test was used to analyse the deviation of views from ‘neutral’. Challenge due to pests and diseases was significantly higher than hypothesised median of 3 (neutral); Z = 5.198, P< .01. Cost of inputs and lack of finances for maintenance were significantly higher than neutral; Z = 5.061, P< .01 and Z = 3.810, P< .01 respectively. The top five challenges based on Garrett scores were pests & diseases, cost of inputs, maintenance costs, inadequate water, and initial costs. Top-ranked opportunities were integrated pest & disease management, farm-inputs subsidy, information on crop varieties, support from extension and capacity building in water harvesting. Concatenations existed between productivity of greenhouse units with quality of produce, ease of access to markets and profitability of greenhouses. The study recommends stakeholders’ concerted effort towards utilisation of the opportunities identified to enhance sustainable Greenhouse productivity among smallholder vegetable producers","PeriodicalId":144021,"journal":{"name":"East African Journal of Agriculture and Biotechnology","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140702066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One potential solution to replace fishmeal is the use of black soldier fly larvae (BSFL) in aquaponics. The study aimed to explore the effect of substituting fish meals with BSFL meals on the growth performance of lettuce (Lactuca sativa) in aquaponics. The study employed the Randomized Complete Block Design (RCBD). A total of 135 catfish fingerlings were divided into three groups and stocked in nine water barrels of 100 litres each (filled with 60 litres of water). The fingerlings were fed twice a day for a duration of 56 days after a two-week period of acclimatisation using commercial feed. Water was cycled through the hydroponic media grow bed using an automatic timer, with a 15-minute cycle every hour throughout the day and night. Fish meal was replaced with BSFL meal at three different proportions: 0% (BSFL0), 30% (BSFL30), and 50% (BSFL50). The data collected was analysed using One-Way Analysis of Variance (ANOVA) and Kruskal-Wallis tests, followed by Tukey's ad-hoc and Dunn's tests, respectively, utilising JMP 16 software. The results indicated that the fresh leaf weight was significantly influenced by the diet types (p<0.05). However, no significant effect was observed on root weight, total dry weight, number of leaves, or root length (p>0.05). This study suggests that black soldier fly larvae meal can successfully replace up to 50% of fishmeal in aquaponics without compromising lettuce growth performance.

This was done to evaluate the effects of graded levels of maggot meal-based multi-nutrient block on feed intake, daily weight gain, feed conversion ratio and internal organs weight during feeding for 56 days at Chinhoyi University of Technology farm. Feed formulation was done using I.D.T Try and Error Iteration software. Sun-dried maggot meal was used to produce four iso-nitrogenous and iso-energetic treatment multi-nutrient block diets with 0%, 5%, 10% and 15% maggot meal.
