A Search for Suitable Growing Environment for Sesame Production in Nigeria

Abstract

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.
