Influence of foliar application of nutrition in greengram (Vigna radiata L.) under sodic soil reclaimed with marine gypsum

Abstract

Application of Marine gypsum and foliar nutrients in greengram (Vigna radiata L.) could be evaluated in Anbil Dharmalingam agricultural college and research institute during summer season in the year of 2021.Randomised block design was used in this experiment with 8 treatments. Foliar spray of 1% Mono potassium phosphate, Salicylic acid (100 ppm), Brassinosteriod (0.5 ppm) were given as combination at 30 DAS (Days after sowing) and 45 DAS including soil application with marine gypsum and without marine gypsum. Observation of growth attributes (plant height, number of branches, number of nodules and leaf area index) was observed at different growing periods. The results of the study reported that combined application of marine gypsum with 1% MKP + 100 ppm Salicylic acid + 0.5 ppm Brassino steroid to increased the plant height (56.57 cm), number of branches (3.57), number of nodules (11.00) and leaf area index (4.69) of green gram.
