Foliar Application of Water Soluble Fertilizer on Growth and Yield of Rainfed Blackgram (Vigna mungo (L). Hepper)

Field experiment was conducted at The Indian Agriculture college, Radhapuram during December 2019 – February 2020. To evaluate the effect of foliar application of water soluble fertilizer on growth and yield of of blackgram under rainfed conditions. Nine treatments were tested in randomized block design with three replications. Among the treatments, application of RDF + Foliar spray of 1% 19:19:19 on 15 DAS + Foliar spray of 1% 12: 61:0 30 DAS + Foliar spray of 1% 13:0:45 on 45 DAS proved its superiority through highest dry matter production (DMP) of 795, 2517 and 4670 kg ha-1 over the other treatments on 30, 45 DAS and harvest respectively. Significantly higher grain yield (733 kg ha-1) was recorded in application of RDF + Foliar spray of 1% 19:19:19 on 15 DAS + Foliar spray of 1% 12: 61:0 on 30 DAS + Foliar spray of 1% 13:0:45 on 45 DAS.
