Effect of foliar nutrition on yield and economics of mungbean [Vigna radiata (L.) Wilczek]

A field experiment was carried out during kharif season of 2016 and 2017 at M.G.C.G.V., Chitrakoot to evaluate the effect of foliar nutrition on productivity of mungbean. Treatment consisted T₁: Control (Water spray), T₂: Foliar spray of Urea 2% at flower initiation, T₃: Foliar spray of TNAU Pulse Wonder @ 5 kg/ha at flower initiation, T₄: Foliar spray of Salicylic Acid 75 ppm at flower initiation and 7 Days after first spray, T₅: Foliar spray of NPK (18: 18: 18) 2% spray at flower initiation, T₆: Foliar spray of Urea 2% + Salicylic Acid 75 ppm at flower initiation, T₇: Foliar spray of Boron 0.25 ppm at flower initiation and T₈: Foliar spray of Nitrobenzene 500 ppm at flower initiation. Result showed that yield attributes viz. pods/plant and pod length was observed statistically superior under foliar spray of Salicylic Acid 75 ppm at flower initiation and 7 Days after first spray while, grains/pod and seed weight/plant was obtained numerically higher under of Nitrobenzene @ 500 ppm at flower initiation. Seed yield (545 kg/ha) and net returns (Rs 30578/ha) was recorded significantly superior under foliar spray of urea 2% + salicylic acid 75 ppm at flower initiation followed by Boron @ 0.25 ppm at flower initiation (523kg/ha; Rs 29905/ha) and urea 2% spray at flower initiation (520kg/ha; Rs 29937/ha) which gave by a margin of 124 kg (29.45%), 102 kg (24.22%) 99 kg (23.51%) higher seed yield and Rs 10093 (49.27%), Rs 9420 (45.98%) and Rs. 8752 (42.72%) greater net returns over control, respectively. Significant higher benefit: cost ratio was noted in urea 2% spray at flower initiation (2.59) followed by of urea 2% + salicylic acid 75 ppm at flower initiation (2.58).
