The field experiment was conducted at experimental plot of Department of Vegetable Science, Kittur Rani Channamma College of Horticulture, Arabhavi, 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.
