Effect of organic formulations on yield, quality, nutrient content and economics on summer greengram (Vigna radiata L.)

Abstract

A field experiment was conducted to study the effect of organic formulations on yield, quality, nutrient content and uptake and economics on summer greengram (Vigna radiata L.) during the year 2021 at Department of Seed Technology, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar. Twelve treatments combinations comprising of 75% RDF with foliar spray of vermiwash, matka khad, cow urine each @ 10% and panchgavya @ 4% at 30 and 45 DAS, foliar spray of panchgavya @ 4% either with vermiwash, cow urine or matka khad @ 10% at 30 DAS, foliar spray of vermiwash either with matka khad or cow urine, all @ 10% at 30 DAS, foliar spray of cow urine and matka khad each@ 10% at 30 DAS, foliar spray of water at 30 and 45 DAS as well as 100% RDF were tested in Randomized Block Design on loamy sand soil. It is concluded that RDF (75%) with foliar spray of panchgavya @ 4% and cow urine @ 10% at 30 DAS resulted in significantly higher yield attributes viz., pods/plant (29.2), seeds/pod (12.34), seed (1987 kg/ha) and stover (4437 kg/ha) yield. The maximum nitrogen and phosphorus uptake (kg/ha) by stover as well as net return (₹ 97754) and BCR (3.81) were recorded with the same treatment. Considering the yield and profitability, it is concluded that summer greengram should be applied with 75% RDF (15:30:00 kg/ha N:P2O5:K2O) and foliar spray of panchgavya @ 4% along with either cow urine or vermiwash each @ 10% at 30 days after sowing.
