Abstract:
The field experiment was carried out on “Studies on effect of foliar application of water soluble fertilizers on growth and available nutrient of black gram” during kharif 2020- 2021 at College of Agriculture, Latur. The experiment was laid out in randomized block design with nine treatments and three replications. The growth and uptake of nutrient attributes of black gram were significantly influenced due to foliar application of black gram. The treatment T₉ (RDF + foliar application of 19:19:19 @ 0.5%, 0:52:34 @ and 13:00:45 @ 1.0% at 25, 35 and 45 DAS, respectively), recorded significantly increased plant height, number of branches plant^-1 (8.98) and number nodules plant^-1 (22.33), leaf area (680 cm²) and leaf area index (2.27), over rest of treatments. of black gram increased significantly due to the treatment foliar application of 19:19:19 @ 0.5%, 0:52:34 @ and 13:00:45 @ 1.0% at 25, 35 and 45DAS, respectively along with RDF. The pH, EC and calcium carbonate content in experimental soil was not significant due to different treatment of soluble fertilizers. However, organic carbon content in soil was significantly improved due to treatment T₉ (RDF + foliar application of 19:19:19 @ 0.5%, 0:52:34 @ and 13:00:45 @ 1.0% at 25, 35 and 45DAS, respectively). Significantly highest uptake of N (54.81 kg ha^-1 ), P (6.86 kg ha^-1) and K (25.44 kg ha^-1) in seed and straw of black gram were recorded due to treatment T₉ (RDF + foliar application of 19:19:19 @ 0.5%, 0:52:34 @ and 13:00:45 @ 1.0% at 25, 35 and 45 DAS, respectively).
