Study of yield and economics of two different varieties of mung bean (Vigna radiate L.) at different NPK level under guava based agri-horti system in Vindhyan region

Abstract

The experiment was conducted during kharif season of 2017 at the Agricultural Research Farm, Banaras Hindu University-South Campus, Uttar Pradesh. The experiment was laid out in a factorial randomized block design in guava based agri-horti system treatment which was replicated thrice. Inoculation of Rhizobium along with application of N (40 kg ha-1) + P2O5 (50 kg ha-1) + K2O (40 kg ha-1), recorded significantly higher grain and straw yield of green gram than the control. Two varieties were selected HUM-16 & SAMRAT .The highest net return of Rs 93901.03 ha-1 was recorded under inoculation of Rhizobium along with N (40 kg ha-1) + P2O5 (50 kg ha-1) + K2O (40 kg ha-1) with HUM-16 variety while minimum return Rs 75781.30 ha-1 was found in control. Higher benefit cost ratio 3.01was observed with N (40 kg ha-1) + P2O5 (50 kg ha-1) + K2O (40 kg ha-1) + Rhizobium with HUM-16. Application of N 40 kg ha-1 + P2O5 50 kg ha-1 and K2O 40 kg ha-1 brought about 668.16 kg ha-1 of grain yield of variety hum-16 with 3.01 ratio of B:C.
