Abstract
During Zaid, 2022, a field experiment was conducted at Crop Research Farm, Department of Agronomy, Sam Higginbottom university of Agriculture, Technology and Sciences, Prayagraj (U.P). The soil in experimental plot was found to be sandy loam in texture, nearly neutral in soil reaction (pH 7.1). The soil had 0.76% natural carbon, 269.97 kg/ha available N and 33.09 kg/ha available P. The treatments applied were Panchagavya (30 ml/lit), Jeevamrutha (250 ml/lit), cow urine (100 ml/lit), with the spraying schedule of every 7, 10 & 15 alternative intervals. The experiment plot was designed in a randomized block of nine treatments, three times each. Based on the objectives taken, maximum plant height (88.07 cm), total number of branches (5.02/m2), number of nodules (40.87), plant dry matter accumulation (20.66 g/plant), maximum number of pods per plant (25.67), number of seeds per pods (11.60), seed yield (1.62 t/ha), stover yield (3.89 t/ha), biological yield (5.54 t/ha) were observed significantly higher in treatment combination of Panchagavya (30 ml /lit) spraying interval at 10 days interval. However, the maximum gross returns (₹ 97,200.00/ha), net returns (₹ 61,385.00/ha), and benefit: cost ratio (1.71) was found to be higher in Panchagavya (30 ml /lit) spraying interval at 10 days interval treatment combination.
