Crop Quality, Groundnut, Fertilizers, Profitability
Soil degradation has adverse effects on the growth, development and yield, hence quality and profitability of agricultural produce, as such, appropriate utilization of fertilizer resources could enhance crop yield, thus quality and profitability of crops. This study focused on the contribution of fertilizer and genotype to some nutritional qualities and profitability of groundnut in an experiment laid out in a Randomized Complete Block Design (RCBD) at the Sokoine University of Agriculture Morogoro, Tanzania with three improved groundnut genotypes (Mangaka, Masasi and Pendo) using Minjingu mazao and DiAmmonium Phosphate as sources of Calcium and Phosphorus,respectively. Data was subjected to ANOVA using GENSTAT 14th software and means separation were made using Least Significant Difference (LSD) at 5% significance level. Results from the study showed significant influence of fertilizer and groundnut genotype on crop quality and profitability. Genotype x fertilizer interactions showed significant effect of calcium on kernel size, protein and oil contents of all genotypes, whereas the application of phosphorus significantly influenced yield and profitability. A value cost ratio (VCR) of >2.0 as obtained from the study is an indication that sustainable fertilizers use could enhance crop quality, hence profitability of groundnut. Further research involving fertilizer treatment combination in multi-locational trials, as well as other nutritional parameters of groundnut crop are suggested to determine specific recommendations for calcium and phosphorus as sustainable nutrient supply contribute to higher productivity of groundnut is crucial to curtailing nutrition security and farmers’ income.
