Influence of Organic Manures and Organic Sprays on Productivity and Economics of Summer Greengram [Vigna radiata (L.) Wilczek]

A field experiment was conducted to investigate the influence of organic fertilizers and organic sprays on the productivity and economic parameters of summer greengram (Vigna radiata) cultivation. The experiment was designed as a split-plot design with three replications. The primary plots encompassed four organic fertilizer treatments: Control (M1), Farm yard manure (M2), Vermicompost (M3), and Poultry manure (M4). The sub-plots included three organic spray treatments: Control (S1), Panchagavya (S2), and Jeevamrutha (S3).

The results of the experiment revealed that the combination of poultry manure as the organic fertilizer in conjunction with the application of Panchagavya spray had the most significant impact on both seed yield (779 kg ha-1) and haulm yield (1909 kg ha-1) for summer greengram cultivation. Furthermore, this specific combination demonstrated notably higher gross returns (₹48,648 ha-1), net returns (₹30,125 ha-1), and a favourable B C ratio of 2.60.
