Effect of Foliar Application of Water-Soluble Fertilizers for Yield and Economics of Rice Fallow Blackgram (Vigna mungo (L). Hepper)

Abstract

Field experiment was conducted at farmer field in kadukkarai village, Kanyakumari during 
February 2021 – April 2021 to evaluate the Effect of foliar nutrition for maximizing the productivity 
of rice fallow blackgram (Vigna mungo (L). Hepper). 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 
significantly recorded highest grain yield (723 kg ha-1) and haulm yield (2320 kg ha-1). However, the 
highest gross return (Rs.53, 955), net return (Rs.41, 305) and BC ratio (3.27) were recorded the 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.
