A field experiment entitled "Effect of nitrogen, phosphorous and boron on growth and seed yield of Dolichos bean (Lablab purpureus L.) var. Arka Amogh” was carried out with ten treatments and three replications in Randomized complete block design with varied level of nitrogen, phosphorous and boron to study the growth and seed yield of dolichos bean var. Arka Amogh. It was observed that T10 with highest NPK (35:70:50 kg/ha) + FYM (15 t/ha) + B (1.5 kg/ha) produced maximum plant height (96.2 cm), leaves/plant (34.6), average leaf area (335.6 cm²), number of pods/plant (33.7), number of seeds/pod (4.3), 100 seed weight (32.71 g), average seed yield/pod (1.407 g), total seed yield/ha (2844 kg), total marketable seed yield/ha (2480.4 kg), lowest unmarketable seeds/ha (363.6 kg) which was found to be at par with T8 with NPK (35:70:50 kg/ha) + FYM (15 t/ha) + B (1.5 kg/ha). So, from the experiment, it can be concluded that the fertilizer dose of NPK (35:70:50 kg/ha) + FYM (15 t/ha) + B (1.5 kg/ha) should be applied to get better plant growth and higher marketable seed yield/ha in dolichos bean, var. Arka Amogh.
