Influence of Cow Based Liquid Manures and Spraying Frequency on Growth and Yield of Green Gram (Vigna radiata L.) Under Natural Farming

Abstract

A field experiment was conducted at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P) during Kharif, 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 (3%), Jeevamrutha (500 lit/ha), cow urine (2500 lit/ha), and spraying schedule on every 7, 10 and 14 different days. The experiment was laid out in Randomized Block Design with nine treatments each replicated thrice. Based on the objectives taken maximum plant height (88.07 cm), number of total branches (5.02), number of nodules (40.87), plant dry matter accumulation (20.66 g/plant), number of pods/plant (25.67), number of seeds/pod (11.60), seed yield (1.65 t/ha), stover yield (3.89 t/ha), biological yield (5.54 t/ha) were recorded significantly higher in treatment combination of Panchagavya spraying interval at 10 days interval.
