Nitrogen, Phosphorus and Compost Effect on the Growth, Yield, and Seed Quality of Bambara Groundnut (Vigna Subterranea)

Bambara groundnut (Vigna subterranea) is an indigenous African crop. The aim of this study was to determine the effect of nitrogen, phosphorus and compost on the growth, yield, seed quality and bacterial population of Bambara groundnut. A glasshouse pot experiments were conducted in ladang 15 at the Faculty of Agriculture; Universiti Putra Malaysia. Ten treatments of this experiment were the combination of nitrogen and phosphorus, B-green biofertilizer and different rates of compost Randomized complete block design (RCBD) with four replications was used. The mineral composition of the seed was determined by used dry ash method. Crude protein was estimated by using protein analyzer unit. The vegetative growth and yield of the plant i.e. plant height (20.65cm), leaves number (262), branch number (86.50), leaf area (2140.54 cm2), pod number (47.25) was attained at highest level of N and P (N30 + P60 kgha-1) application. The highest nodule number (31.50) and bacterial population (138.50) were recorded at biofertilizer 15 kgha-1. From the results, it showed that the seed contain 20.30% protein, 3.88% ash, glumatic acid 19.48%, lysine 6.08%, 66.33 mg/100g Ca, and 65.05 mg/100g Mg. Different levels of fertilizer have not major changes in the nutritional value of Bambara groundnut. Nitrogen and phosphorus fertilizer had positive impact on yield and seed quality. Combination application of N and P (N30 + P60 kgha-1) increased the growth, yield and seed quality of Bambara groundnut. But bacterial population was increased with the application biofertilizer (15 kg ha-1). Keyword - Bambara ground nut, Nitrogen, Phosphorus, Yield and Seed qulaity
