Efficacy of Liquid Organics on Growth and Yield of Cowpea under Natural Farming

Abstract

A field experiment was conducted at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P) during Zaid, 2022. The soil of the experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), organic carbon (0.75%), available N (269.96 kg/ha), available P (33.10 kg/ha), and available K (336 kg/ha). The treatments applied were of Panchagavya (2, 4 and 6 %) and Jeevamrutha 500 and 1000 l/ha. The experiment was laid out in Randomized Block Design with nine treatments each replicated thrice. Based on the objectives taken maximum plant height (84.34 cm), number of total branches (5.34), number of nodules (40.87), plant dry matter accumulation (17.96 g/plant), number of pods per plant (25.47), number of seeds per pods (11.78), seed yield (1.78 t/ha), stover yield (3.99 t/ha) and biological yield (5.77 t/ha) were recorded significantly higher in treatment combination of Panchagavya (6 %) + Jeevamrutha 1000 l/ha. Further, the maximum gross returns (₹ 71200.00/ha) and net returns (₹ 31300.00/ha) were recorded higher in treatment combination of Panchagavya (6 %) + Jeevamrutha 1000 l/ha. However, B:C ratio was highest in 1.78 Panchagavya (2 %) + control.
