The economic relevance of farm management practices to the production of sesame crops in Nigeria includes preventing and combatting food crises, actualization and realization of national food security as well as enhancing gross domestic product. This research seeks to examine the edaphology of some soil types in relation to the productivity of sesame crops in Nigeria. The experiment was conducted in statistical farm of Hussaini Adamu Federal Polytechnic, Kazaure, Jigawa State, Nigeria during 2019 growing season. The experimental design was Completely Randomized Design with one hundred replications. There were three types of soils investigated; Clay, Sandy, and Loamy were compared with one another. The soils were made free of any nuisance factors effects. The chlorophyll content of the plants was read using Konica Minolta chlorophyll meter SPAD-502 plus, and the data analyzed using one-way ANOVA and the Statistical Package for Social Sciences (SPSS) version 20. The result of the analysis indicates a higher significant effect of Sandy soil (M = 11.20, SD = 2.37) on the yield of sesame crops in this region as compared to the effects of the Clay (M = 3.60, SD = 0.89), and Loamy (M = 6.86, SD = 3.39) soils. The overall ANOVA test indicates that growing environment does have effect on sesame production, F (2, 27) = 6.70, p = 0.00. However, the result indicates insignificant chlorophyll mean difference between Clay and Loamy soils. It is therefore evident from these results and the reviewed literatures that the suitable growing environment for sesame production in Nigeria is fertile Sandy soil that is deep, light textured, well-drained and that is exposed to an average temperature of 25oC to 37oC. The crop is also tolerant to draught, but not at the germination and seedling stages, water logging, and excessive rain fall while it requires 90–120 frost-free days to achieve optimal yields in cold regions. The challenges which stand in the way of increasing the productivity and quality of sesame crops need to be overcome. As with other crops, which is a major export crop in many countries, these crops should be given more research attention.
Cirebon Regency, which is one of rice production centers in West Java Province, has experienced the conversion of paddy fields to non-agricultural land. The conversion caused the decline in rice production, which automatically reduces its contribution to West Java Province. The objective of this research is to build a paddy food sufficiency model as a direction to develop food sufficiency in Cirebon Regency, West Java, Indonesia. Secondary data used were sourced from various reports and documents of relevant time series from several authorities, while primary data were obtained from research in the area. The model uses a dynamic system approach. The results of the study showed that in 2031, area of paddy fields which should be protected increased, the number of farmers decreases, food sufficiency decreases, the area of paddy fields decreases, and farmers’ income increases. The application of moderate or optimistic scenarios can reduce the area of paddy fields which should be protected, increasing food sufficiency as well as farmer’s income. The spatial analysis results in land which is suitable and available which can be defined to become sustainable food agriculture land through a review process of the official spatial land-use plan.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
