Abstract

The study was carried out to examine the effect of plant density and phosphorus fertilizer on performance of mungbean (Vigna radiata(L) Wilczek) grown on soils derived from basement complex parent material at the Abubakar Tafawa Balewa University Teaching and Research farm Bauchi. The land was prepared and soil samples collected at the 0-20cm depth for laboratory analysis, the analytical results showed that the soil was moderately acidic and had low total nitrogen, available phosphorus and organic carbon contents. The treatment variables consisted of four phosphorus levels (0, 20, 30 and 40 kgPha-1) and three intra-row spacing (20, 30 and 40 cm).These treatments were combined using factorial method and laid out in a randomized complete block design, with three replications. Results obtained showed that plant dry matter yield at 8WAS, pods and seed yield were significantly influenced by density/ spacing with the higher spacing giving higher plant dry matter than the lower spacing, while lower spacing gave higher pod and seed yields. The application of phosphorus fertilizer only had significant effect on pod and seed yields. It is concluded that lower spacing (250.000 plant population density) and 30 – 40 kg ha-1 phosphorus fertilization enhances the performance of mungbean and therefore recommended for the type of soil studied.
