Walp.) is the most important source of plant protein consumed in Nigeria with major supplies coming from the northern part of the country. However, reduction in supplies due to insurgency resulted in sharp increases in price, especially in Southwest Nigeria where cowpea is relished in different delicacies. Sustainable production increase in suitable Southwest agro-ecologies depends on suitability of cultivated varieties and production practices of the farmers. A study was conducted to identify cowpea varieties cultivated by farmers, the varietal attributes, farmers’ preferences, and production constraints. Data were generated through a farm survey of 120 farmers selected by multi-stage sampling technique in Ondo and Oyo States of Southwest Nigeria. Cowpea production was male dominated, with 20.8 % of cultivated area allocated to its production, averaging 0.96 ha per farm household, fragmented over circa three locations. Local varieties were cultivated by 51.6 % of the farmers with seeds sourced mainly from local markets (62.7 %). Cowpea was mainly cultivated as intercrop (55.1 %) notably with cassava. Herbicides and insecticides were prominently used by the farmers while fertiliser was hardly used for cowpea production (12.8 %). Notable attributes cherished by farmers included brown or white coat colour, smooth texture and medium sized grains, erect or creeping growth pattern, and long pod length. Average yield of cowpea on farmers’ field was 530 kg ha −1 while inadequate access to quality seeds, incidence of field insect pests, and rodents (storage pest) were identified as the most severe production constraints by the farmers. Community-based seed production systems should be introduced for improved access to quality seed.","PeriodicalId":54889,"journal":{"name":"Journal of Agriculture and Rural Development in the Tropics and Subtropics","volume":"119 1","pages":"43-52"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67543486","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}

At first, our participatory evaluation in Senegal showed that (i) local materials needed for seedball production are locally available, (ii) the technology conforms to the existing management systems in the Sahel, and (iii) socio-economic conditions do not hinder seedball adoption. Afterwards, seedball was mechanically and chemically optimised. Pearl millet seedlings derived from the seedball variants were grown and compared to the control under greenhouse conditions. Our results showed that the combination of 80 g sand + 50 g loam + 25 ml water is the standard seedball dough, which produces about ten 2 cm diameter-sized seedballs. Either 1 g NPK fertiliser or 3 g wood ash can be added as nutrient additive to enhance early biomass of pearl millet seedlings. Ammonium fertiliser, urea and gum arabic as seedball components hampered seedlings emergence. Seedball + 3 g wood ash and seedball + 1 g NPK-treatments enhanced shoot biomass by 60 % and 75 %, root biomass by 36 % and 94 %, and root length density by 14 % and 28 %, respectively, relative to the control. Shoot nutrient content was not greatly influenced by treatment. However, multiplying biomass yield with nutrient content indicates that nutrient extraction was higher in nutrient-amended seedballs. On-station field tests in Senegal showed over 95 % emergence under real Sahelian conditions. Since early seedlings enhancement is decisive for pearl millet panicle yield under the Sahelian conditions, on-farm trials in the Sahel are recommended.","PeriodicalId":54889,"journal":{"name":"Journal of Agriculture and Rural Development in the Tropics and Subtropics","volume":"60 1","pages":"67-79"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67543562","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}

However, in the recent past, a growing trend of such groups has been observed in the pastoral areas in northern Kenya. This study therefore explores how these groups have emerged since Kenya’s independence in 1963 to date, and which factors have contributed to their evolution. A full survey on all income-generating community groups was conducted and different types of interviews were used to elicit the perspectives of members of the community and external development actors. The findings on the history of group formation show the roles played by different entities over time and reveal how and why various factors influenced group formation. The characterisation of all 153 income-generating groups found in Marsabit South showed the diversity of the different group activities and yielded information on the reasons why usually a combination of different income-generating activities is practised. The collective group activities offer a possibility for income diversification for pastoralists despite labour constraints posed by key domestic and livestockmanagement tasks. The findings explain why community groups are increasingly gaining importance in pastoral areas, as a means to solve problems and fulfil diverse needs at household and community level.","PeriodicalId":54889,"journal":{"name":"Journal of Agriculture and Rural Development in the Tropics and Subtropics","volume":"119 1","pages":"53-66"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67543547","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}
