Abstract

A field experiment 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 effect of nitrogen, phosphorous and boron on seed yield, seed quality and economics of Dolichos bean (Lablab purpureus L.) 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 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), highest germination percentage (92.7 %), vigour index-1 (3487.37), vigour index-2 (12672.23) and highest B:C ratio (3.79) 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 higher marketable seed yield/ha with better quality and fetch more profit in seed production of dolichos bean, var. Arka Amogh.

Conclusion

Based on the findings of the experiment, it can be concluded that a fertilizer dose of NPK (35:70:50 kg/ha) + FYM (15 t/ha) + B (1.5 kg/ha) should be used to achieve a better quality marketable seed yield/ha and fetch higher profit in seed production of dolichos bean, var. Arka Amogh.
