Effect of foliar application of nutrients on yield and economics of blackgram (Vigna mungo {L.} Hepper) under rainfed Vertisols of Central India

Abstract

An experiment was conducted to study the effect of foliar application of nutrients on yield and economics of blackgram under rain fed condition during kharif 2014 at the Research Farm of AICRP on MULLaRP, R.A.K. College of Agriculture, Sehore (M.P.). The experiment was laid out in Randomized Block Design with three replications having nine treatments namely Control, only water spray, Urea 2% spray at flowering, DAP 2 % spray at flowering and 15 days later, Urea phosphate 2 % spray at flowering, MOP 2 % spray at flowering, TNAU pulse wonder @ 5 kg ha-1 at flowering (contains- N, P, K, Boron, Fe and auxin), Brassinolide 0.75 ppm at flowering, Salicylic acid 100 ppm at flowering, 19:19:19 of NPK as 2 % spray at flowering. Application of 2 % DAP spray at flowering and 15 days later recorded highest yield and higher net return and being on par closely. Followed by application of 19:19:19 (NPK) as 2 % spray at flowering stage. It is concluded that application of 2 % DAP spray at flowering and 15 days later is more remunerative than application of 2 % 19:19:19 (NPK) spray at flowering stage. Further the different treatments had positive effect on yield, and economics of black gram.
