Effect of foliar application of nutrients on growth and development 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 growth and development of black gram (Vigna mungo (L.) Hepper) under rain fed condition during kharif season 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 T1 [Control (water spray)], T2 [Urea 2% spray at flowering], T3 [DAP 2% spray at flowering and 15 days later], T4 [ Urea phosphate 2% spray at flowering], T5 [MOP 2% spray at flowering], T6 [TNAU pulse wonder @ 5 kg ha-1 at flowering (contains- N, P, K, Boron, Fe and auxin)], T7 [Brassinolide 0.75 ppm at flowering], T8 [Salicylic acid 100 ppm at flowering], T9 [19:19:19 (NPK) 2% spray at flowering]. Growth attributing characters i.e. plant height, branches/plant, root length, number and dry weight of root nodules, were significantly influenced with the different treatments and recorded higher values with the foliar application of DAP 2% spray at flowering and 15 days later. Dry weight per plant was significantly influenced by different foliar nutrition and recorded higher value with application of DAP 2% spray at flowering and 15 days later. From this study it may be concluded that different treatments had positive effect on yield, and growth of black gram. Application of DAP 2% spray at flowering and 15 days later recorded maximum yield (916 kg/ha) and higher net return (23313
