Effect of Various Organic and Inorganic Sources of Nutrients on Growth, Yield, and Economics of Kharif Greengram [Vigna radiata. (L.) Wilczek] in the Bundelkhand Region, India

Abstract

The application of organics alone does not result in a dramatic rise in crop yields due to their low nutritional status and large quantity demand, which is also a restriction. As a result of the aforementioned implications, Greengram may now be grown using a combination of organic and inorganic fertilizers, as well as bio-fertilizers. There for a felid experiment was conducted in Effect of various organic and inorganic sources of nutrients on growth, yield, and economics of Kharif Greengram [Vigna radiata. (L.) Wilczek] in the Bundelkhand Region.The experiment was laid out in randomized block design with 3 replication having 10 treatments. The application of Rhizobiumculture @ 25g/kg of seed along withVermicompost @ 2.5 t ha-1; FYM @5 t ha-1and 100% RDF was found significantly superior in plant height (69.90cm), number of leaves per plant (60.50), leaf area index (1.88) and Number of Rhizobium nodules plant-1 (123.37) at 45 DAS, number of branches (8.43), Plant dry matter (362.11 g m-2), pods plant-1 (28.60), grain pod-1 (11.20), Length of pods (9.87cm), Seed index (4.50g), grain yield (11.41q ha-1), and straw yield (27.45q ha-1), Gross monetary returns(82330 Rs ha-1) were found higher in same treatment T10, as compared to other combination and control. However, highest benefit: cost ratio (3.44) was recorded with use of Rhizobium culture and application of 100% RDF (T2) as compared to other combination and control.
