RCDL-10. The experiment was laid out in Split Plot Design with six treatments as month of sowing (May, June, July, August, September and October) allocated in main plots and four phosphorus levels (30, 40, 50 and 60 kg/ha) allocated in sub-plots with three replications. The results recorded showed that May month of sowing took the least number of days to reach first flowering, flowering to pod development, pod development to horticultural maturity; highest number of flowers per panicle, highest number of pods per plant, highest number of seeds per pod, highest fresh weight of pods, highest pod yield per plant (168.70 g) and pod yield per hectare. The May month of sowing also registered highest crude protein content of the pods, highest total nitrogen, total phosphorus and total potassium uptake by the plant Phosphorus dose of 60 kg/ha recorded the highest plant growth, maximum number of flowers per panicle, longest pod length, highest fresh weight and dry weight of pods, highest number of pods per plant, highest number of seeds per pod, highest pod yield per plant (123.04 g) and projected yield per hectare. It also recorded maximum crude protein content of the pods, highest total nitrogen, total phosphorus and total potassium uptake by the plant Hence, it can be concluded that as compared with late sowing, early sowing in the months of May and June resulted in higher yield and yield attributes, even with low levels of phosphorus applied. Fertilization with phosphorus dose of 60kg/ha produced better results, as compared to the lower phosphorus doses in all aspect The nutrient uptake (N, P and K) was maximum in early sowing (May and June month of sowing) and at higher levels of phosphorus fertilization (50 and 60 kg/ha phosphorus).EnglishThesis
