The results on genetic parameters in 43 cluster bean genotypes collected from different parts of the country revealed, high estimates of variation for number of branches at 45 and 90 days after sowing (DAS), number of pods per cluster, number of clusters per plant, number of pods per plant, vegetable pod yield per plant, weight of ten pods, seed endosperm gum content, plant spread (E-W), plant spread (N-S), and vegetable pod yield per plot. The high estimates of heritability coupled with high values of genetic advance over mean (GAM) were observed for the characters number of branches at 45 DAS, plant height at 90 DAS, number of branches at 90 DAS, stem girth, plant spread (E-W), plant spread (N-S), number of pods per cluster, number of clusters per plant, number of pods per plant, pod length, vegetable pod yield per plant, vegetable pod yield per plot, weight per ten pods, hundred seed weight, seed yield per plant, seed endosperm gum content, protein content in seeds indicates predominance of additive component for these traits and hence direct selection would be more effective in improving these traits.

during the growing period of 2016-17 and 2017-18 to investigate the effect of different N, P and K interaction levels on nutrient uptake by dolichos bean and post harvest fertility status of soil. The field experiment was laid out in randomized block design comprising of eighteen treatments replicated thrice. Amongst all NPK fertilizer levels, higher fertilizer dose of 25:75:50 kg NPK per hectare recorded significantly maximum plant height, number of secondary branches and dry matter content per plant at harvest however, it was onpar with 25:75:25 kg NPK per hectare except dry matter content per plant in both the years (2016-17 and 2017-18) and pooled data respectively. However, pooled analysis data revealed that green pod yield per plant and pod yield per hectare as well as higher total N, P and K uptake were recorded significantly maximum in 25:75:50 kg NPK per hectare but the trend was different during both the experimental years. Physico-chemical properties of soil such as soil pH, EC, OC in soil after final harvest of dolichos bean were significantly influenced by NPK interactions levels during both the years (2016-17 and 2017-18) of investigation and in pooled data analysis except soil pH in 2017-18 growing season. Pooled data revealed that significantly highest available nitrogen, phosphorus and potassium availability in soil were recorded in higher fertilizer dose of 25:75:50 kg NPK per hectare which was onpar with 25:75:25 kg NPK per hectare except available potassium. Similar trend was also observed during the year 2016-17 and 2017-18 experimental years.
