Effect of Foliar Application of Nutrients on Growth and Yield Attributing Characters of Black Gram

An experiment was conducted to study the effect of foliar application of nutrients on growth and yield attributing characters of black gram under rain fed condition during kharif season 2015 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 eight treatments namely T1 [Control (water spray)], T2 [Urea 2% spray at flowering], T3 [TNAU plus wonder @ 5 kg/ha at flowering initiation], T4 [ Application of salicylic acid 75 ppm at flower initiation and 7 days after first spray ], T5 [Application of 18:18:18 NPK 2% at flower initiation], T6 [Application of 2%urea +salicylic acid spray at flower initiation], T7 [Application of Boron 0.25 ppm spray at flower initiation] and T8 [Application of Thiourea 500ppm spray at flower initiation stage]. 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 18:18:18 NPK 2% spray at flower initiation stage. Dry weight per plant was significantly influenced by different foliar nutrition and recorded higher value with application of 18:18:18 NPK 2% spray at flowering. From this study it may be concluded that different treatments had positive effect on yield and growth of black gram. Application of 18:18:18 NPK 2% spray at flowering and 15 days later recorded maximum yield (795 kg/ha) , higher net return (27288 /ha) with benefit cost ratio of 1:2.12.
