Effect of Organic Phytohormones on Yield and Economics of Rice Fallow Black Gram (Vigna mungo L.)

Abstract

Background: Field experiment was conducted at the Experimental farm, Department of Agronomy, Bharath Institute of Higher Education and Research, School of Agriculture, Selaiyur, Chennai to trace on the effect of foliar spray of organic phytohormones on yield and economics of rice fallow black gram, during Sornavari (Apr-May) 2023. Methods: The experiment was laid out in Randomized Block Design (RBD) with three replications and seven treatments. T­1 - Water spray T2 -Foliar spray of 3% Panchagavya at 30 and 45 DAS T3 - Foliar spray of 10% Jeevamruth at 30 and 45 DAS T4 -Foliar Spray at 10% Vermiwash 30 and 45 DAS, T5 - Foliar Spray of 10% cow urine at 30 and 45 DAS, T6 - Foliar spray of 3% Panchagavya + 10% Vermiwash at 30 and 45 DAS T7 - Foliar spray of 3% Panchagavya + 10% Cow urine at 30 and 45 DAS. All the treatments imposed significantly influenced the yield and economics of black gram. Result: Among the treatments - foliar spray of 3% Panchagavya + 10% vermiwash (T6) recorded higher seed yield, haulm yield and economics was registered. In contrast, water spray (T1) recorded the least seed yield, haulm yield and economics.
