Response of Foliar Nutrition on Growth and Yield of Urdbean under Rainfed Condition

Field Experiment was conducted during October 2018- January 2019 with an objective to enhance growth and yield of Urdbean under rainfed condition thorough foliar fertilization. The experiment was laid out in randomized block design with seven treatments and replicated thrice. The treatment details includes, T1 Control (Farmer practice), T2 Full RDF, T3 - 50 % RDF and foliar spraying of Revive plus @ 2 g litre-1 twice at 25 and 50 DAS, T4 - 50 % RDF and foliar spraying of Revive plus @ 3g litre-1 twice at 25 and 50 DAS, T5 - 50 % RDF and foliar spraying of 1 % KCl twice at 25 and 50 DAS, T6 50 % RDF and foliar spraying of 100ppm Salicylic acid twice at 25 and 50 DAS, T7 - 50 % RDF and foliar spraying of Orthosilicic acid @ 2ml litre-1 twice at 25 and 50 DAS. The results of the experiments revealed that foliar application of different chemicals significantly influenced the growth, yield attributes and yield. Among the various treatments tried, T4 - Revive plus @ 3g litre-1 twice at 25 and 50 DAS recorded maximum values for growth and yield attributes viz. , plant height, LAI, DMP, root length and chlorophyll content and yield attributes viz. , number of pods plant-1, number of seeds pod-1, test weight, seed yield and haulm yield and harvest index. The lowest values for growth and yield attributes and yield were recorded in T1 Control treatment.
