The study aimed to determine the effect of nitrogen fertilization and irrigation on different levels of treatment on shallot growth and yield in dry land. The experiment was a factorial design in a striped plot with three replications. The first factor was nitrogen fertilizer levels, namely 0 kg N/ha (N0), 80 kg N/ha (N80), 160 kg N/ha (N160) and 240 kg (N240); the second factor was irrigation with four levels, namely 25% ETc (W25), 50% ETc (W50), 75% ETc (W75) and 100% ETc (W100). The variables observed were plant height, number of leaves, fresh weight of tubers, diameter of tubers, dry weight of tubers and harvest index. The results showed that the significant effect of treatment was more due to the main effect of nitrogen fertilizer and irrigation factors. Nitrogen fertilizer has a significant effect on plant height, fresh weight of tubers, tuber diameter, dry weight of tubers and harvest index, while the number of leaves and canopy cover have not been significantly affected. The irrigation treatment significantly affected all observed variables, while only the dry weight variables of tubers showed a noticeable interaction effect of nitrogen fertilization and irrigation. The best treatment to support the growth and yield of shallots in dry land results from fertilizing nitrogen (N) 160 kg N/ha and irrigating 75% Etc.","PeriodicalId":367495,"journal":{"name":"International Journal of Agriculture and Technology","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122946811","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}

A multi-stage random selection method was used to choose the study locations, and 540 farmers were administered with structured questionnaire. Data were analyzed using the descriptive, double difference estimates and FGT poverty index. The results showed that the difference in value between the two output differences [?211,255.8 – ?128,366.86] was N82, 888,94. The poverty incidence of poor farm households in the study area was 95% for the non-adopters, and 61% for the adopters. In addition, the poverty depth among the farm households in the study area was 85% for non–adopters and 36% for adopters. The severity of the poverty index was 79% for non–adopters and 26% for adopters of improved tomato post-harvest loss reduction management practices. This implies that poverty incidence is higher among non-adopting poor than their adopting poor households. The study concluded that the adoption of the improved tomato post-harvest management practices had a positive impact on tomato postharvest loss reduction, income, and poverty status as revealed in the results of this study, although the extent of tomato post-harvest loss was still high. It was therefore recommended that the tomato post-harvest loss reduction campaign should be sustained to further decrease the losses suffered by tomato farmers especially as the end line for achieving the SDG on food loss and food waste draws closer. All stakeholders in the tomato value chain should address other challenges limiting the adoption of improved tomato production and post-harvest loss reduction such as low extension visits, poor market linkages, and distance to market.","PeriodicalId":367495,"journal":{"name":"International Journal of Agriculture and Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126716813","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}

Hence, inadequate production of soybean in Nigeria occasioned by lack of high-yielding improved varieties and unstable yields among others need to be investigated. This study assessed the diversity and yield stability in soybean genotypes for appropriate selection for improvement programme. Twenty- four soybean genotypes obtained from the International Institute of Tropical Agriculture, Ibadan were grown at the Teaching and Research Farms of the Federal University of Agriculture, Abeokuta (Latitude 7°15 ?N and Longitude 3°25 ?E), Institute of Agriculture Research and Training, Ibadan, Oyo State (Latitude 7°23 ?N and Longitude 3°27 ?E) and Lagos State Polytechnic, Ikorodu, Lagos State (Latitude 6°37 ?N and Longitude 3°30 ?E). Plantings were done in Abeokuta in May, 2017, Lagos and Ibadan in May and June, 2018, respectively. The experiments were laid out in a Randomized Complete Block Design with three replicates across the three locations. Data collected were subjected to Statistical Analysis. Results showed that the genotypes evaluated differed significantly (p<0.05) for agronomic characters, indicating the possibility of selecting soybean genotypes with superior seed yield characters. Dendrogram generated from Ward Linkage Clustering grouped the twenty-four soybean genotypes into five clusters, indicating genetic similarity and diversity among the genotypes. The AMMI analysis revealed that the total variance in soybean grain yield accounted for, by genotypes (G), environment (E) and genotype x environment interaction, with values of 43.00, 28.18 and 28.81%, respectively. Genotype TGx2004-10F was unstable across environments, but had high seed yield in Lagos. Genotype Selection Index (GSI), which combines both AMMI Stability Value and mean seed yield, revealed genotypes TGx1990-3F, TGx2010-11F, TGx1990-80F, TGx1991- 10F and TGx1987-62F were stable with higher seed yield across the tested environments. These genotypes are therefore suitable for cultivation across the environments and are thus recommended.","PeriodicalId":367495,"journal":{"name":"International Journal of Agriculture and Technology","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128983998","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}

Proximate composition, vitamins, mineral and anti- nutrient contents of the local formulae as well as the commercially available feeds was evaluated using standard methods and results obtained were compared with each other. Results shows that the nutrient composition of the local feeds formulated from waste material compares favourably well with that of the commercial feed with anti-nutrient (Tannins, Oxalate, Phytic acid, HCN) within FAO tolerable limits. Thirty (30) days feeding trial was conducted to evaluate the growth performance of the broilers fed on locally formulated feed from domestic waste compare with commercial poultry feed. Ten Forty-five (45) day old broiler were randomly allotted into two groups of five (5) birds each. The poultry birds were fed ad-libitum for a period of four weeks and weight gain where recorded every three days. Result shows the significant (P< 0.05) increase on the growth rate of birds fed with commercial poultry feed when compared with those fed with locally formulated feed from domestic waste. Despite this significant growth noticed in birds fed with commercial poultry formulae, it is evidence from the result that the locally made formulae contains lots of nutrients which can support growth of poultry birds and also devoid of additives promotion. Thus, utilization or incorporation of at least 20% of domestic waste in poultry feed can help reduce the cost of livestock production and also ameliorate the burden and dangers possess by the disposal and poor management of domestic waste in the environment while at the same time reducing the act of artificial growth substances added to commercial poultry feed.","PeriodicalId":367495,"journal":{"name":"International Journal of Agriculture and Technology","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121890821","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}

Through research, many agricultural technologies, loaded with potential benefits have been produced but their acceptance by the intended users has been a global challenge. This calls for need to develop effective mechanism to enhance technology acceptance so that their potential benefits may be realised. This study focused on these phenomena through establishment of various factors related to acceptance of improved sugar cane varieties among small-scale sugar cane farmers in Kakamega County. Understanding of these factors was critical, as it would pin point critical conditions that would facillitate wider acceptance of improved technologies by the targeted users. The study was built on Unified Theory of Acceptance and Use of Technology (UTAUT); and the theory of Diffusion of Innovations (DOI). A Cross-Sectional Survey research design was used. The target population was 137,355 sugar cane farmers from Kakamega County, from which a sample of 384 farmers was randomly selected. Questionnaires were used to collect data. Statistical analysis was done using chi-square at 0.05 significance level. The study findings established significant relationships between gender, age, education, land ownership, experience in farming, source of income, sugar cane varietal attributes, variety choice, seed sources, availability of advisory services and marketing of sugar cane, with farmers’ acceptance of improved varieties. Addressing these factors is of great importance to technology developers and promoters as they would facilitate acceptance of the improved technologies produced by farmers. The study recommended extension service providers and sugar millers to provide farmers with adequate information on improved sugar cane varieties, required facilitating resources and supportive services in effort to enhance production of these varieties by farmers. The study has also contributed valuable information to the existing literature in agricultural extension.","PeriodicalId":367495,"journal":{"name":"International Journal of Agriculture and Technology","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128604564","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 was conducted to assess the existing gaps among different genders in the maize production value chain in selected northern States of Nigeria. A field survey was conducted in five major maize-producing States of Kaduna, Nasarawa, Niger, Taraba, and Adamawa. Structured questionnaires were administered to 450 maize farming households across the five selected States using a simple random sampling technique. Focus group discussions (FGDs) and Key Informant Interviews (KII) were in the study area. The Integrating Gender into Agricultural Value Chains (INGIA-VC) Analytical Framework was employed to develop the tools for the study. Data were analyzed using descriptive statistics. Results showed that over 82% of the sampled farm households in each State were male-headed households, whilst only 18% were female-headed households. Male farmers cultivated an average 4.2 ha of farmland compared to 1.8 ha cultivated by female farmers for maize production. Male farmers have more access to other production inputs like fertilizers than female farmers. More female farmers (22%) than male farmers (7.6%) purchase improved seeds directly from seed companies. Maize productivity by male farmers was consistently higher (2–2.5 t ha-1) than female farmers that recorded an average of 0.24 t ha-1 across the States. The lower participation of female farmers in maize production compared to male farmers was attributed to the socio-cultural and religious restrictions placed on females that exclude them from public engagements in northern Nigeria. Awareness creation through the traditional rulers and mechanization of some practices will engender more women and youth participation in maize cultivation.","PeriodicalId":367495,"journal":{"name":"International Journal of Agriculture and Technology","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127057404","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}

A mixed method approach in the form of remote sensing techniques, questionnaires and key informant interviews was used to gather data. Findings indicated the extent of deforestation to be 4254ha (5%) and 10632ha (14%) after the first decade (2000 – 2010) and second decade (2000 – 2020) respectively. Of the cleared forest, the most affected vegetation cover type was the wooded grassland (84%) followed by bushland (31%) and wooded land (10%) after the 20-year period. Respondents identified political gain, expansion of jurisdictions of chiefs and population pressure as the social factors most responsible for accelerated deforestation in Mapfungautsi. Conversely, the identified economic factors mainly contributing to deforestation were agriculture, timber and firewood poaching. The study concluded that agriculture was the single most impactful factor responsible for deforestation as the main social factors (political gain and expansion of chieftaincy) worked in combination to invade and clear protected forests for settlement and agriculture (which is also the main livelihood source of local people). Consequently, any control measures to arrest deforestation in Mapfungautsi and any other protected forests for that matter, will require serious buy-in and will power from political and traditional leaders and other stakeholders like farmers and community members.","PeriodicalId":367495,"journal":{"name":"International Journal of Agriculture and Technology","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121808794","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}
