The development of new soybean cultivars with high efficiency and ability to drought resistance is very important. Field experiment was conducted to investigated the impact of irrigation regimes at different growth stages (Full irrigation, irrigation regimes at vegetable growth, flowering, and pod full stages) on yield and yield components of two soybean varieties (1448 and Egyptian) under semi-arid regions. The results indicated that irrigation regimes had significant effect on most of traits except the weight of plant. The pod full stage higher affected by the drought than other stages on most of parameters tested. Irrigation regimes at pod full stage reduced the number of pods plant -1 by 38.4 and 26.0%, weight of pods plant -1 by 23.7 and 53.6%, number of seeds plant -1 by 29.0 and 28.8%, seeds weight plant -1 by 17.2 and 38.8%, 100-seeds weight by 35.3 and 38.1% for 1488 and Egyptian respectively. While, irrigation regimes at flowering stage decreased the weight of plant for Egyptian by 57.5% and seed yield by 24.4 and 31.2% for 1448 and Egyptian respectively as compared with same variety at full irrigation. Varieties had significant differences on plant weight, number of pods plant -1 , number of seeds plant -1 , harvest index, and seeds yield. In conclusion, the soybean cultivars used in this study were very sensitive to water stress. The 448 cultivar is recommended due to having higher seed yield and yield components in the study conditions.","PeriodicalId":7540,"journal":{"name":"African Journal of Agricultural Research","volume":"78 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139130592","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}

The objective of this study was to investigate the mid/long-term effects of a single biochar application on soil physical properties, growth parameters and the yield of soybeans in a sandy clay loam. Biochar was added to a highly weathered tropical soil at rates of 40 tons ha-1 five years prior to this study (2017 to 2022). Soybeans were grown in the biochar-amended soils and the control in the 2021/2022 season. Biochar amendment significantly increased porosity, biological activity, improved soil structure type and grade, increased the initial and basic infiltration rates, and lowered the bulk density. Soybean growth characteristics, such as shoot length, weight, and diameter at the base; root weight, pod number, and grain yield, were significantly improved by biochar. The improved agronomic performance of the crop was attributed to improved rooting conditions, soil water-holding capacity, and nutrient use efficiency promoted by biochar amendment. Thus, biochar is a promising practical approach to improve soil agronomic properties, nutrient acquisition, and the yield of soybeans in a sustainable way on sandy clay loam soils.","PeriodicalId":7540,"journal":{"name":"African Journal of Agricultural Research","volume":"109 35","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139133704","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}

Coffee, cotton, and honey are produced for sale in South and Western Ethiopia. As honey emerged as a cash commodity, farmers in Northern Ethiopia became involved in honey production as an income source. Studies on honey production have focused on central, south, and western Ethiopia. Northern and eastern Ethiopia are perceived as arid and most degraded, and they are not favorable for beekeeping. This study analyzes the market chain of honey production and questions why farmers engage contrary to the literature and established perceptions. A questionnaire was administered to a total of 1609 honey farmers who were selected randomly from the list of beekeepers in the agricultural office, including desk reviews and key informant interviews. Both descriptive and inferential statistical analyses were conducted. The descriptive data results show that nine out of ten honey products in the market are supplied by smallholders to consumers and retailers. Out of this, six out of seven are supplied directly to consumers. The inferential data results indicate that producers' experience, income, bee colony size, use of modern hives, and the lagged price of honey determine the marketable supply of honey. Both data results confirm that honey production is profitable in Northern Ethiopia. The use of modern beehives enhances productivity and income by 27%. However, shortages of bee forage (due to drought-induced changes), credit, technologies, knowledge, markets, and bee diseases are key problems for beekeepers that require policy intervention.","PeriodicalId":7540,"journal":{"name":"African Journal of Agricultural Research","volume":"320 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139204757","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}

This study, therefore, sought to examine the physio-chemical properties of soils in Buyende and Serere districts, in the Kyoga basin, Uganda. Using soil auger, soil samples were purposively picked from Serere (23) and Buyende (17) districts at depth of (0-25 cm).  Routine soil analysis was done for the macro soil nutrients of pH, nitrogen, phosphorus, organic matter, potassium, and soil texture. The physio-chemical properties were then subjected to statistical analyses to assess the soil properties variability using the coefficient of variation. The study also examined Soil Structural Stability Index and mapped the spatial distribution of soil physio-chemical properties using ArcMap10.2.2. Results indicated that the soil physio-chemical properties varied spatially and sandy clay loam was identified as the major textural class (Serere (52.2%) and Buyende (47.2%)). Additionally, Soil structural stability index results showed that the soils were structurally degraded across the two districts. The study recommends that the government and NGOs intervene by revising policies and providing subsidies that support farmers to test their soils as well as other farm inputs that improve soil fertility.
