Influence of Cow Based Liquid Manures and Spacing on Growth and Yield of Cowpea (Vigna unguiculata 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 Combination of liquid organic manures Panchgavya and jeevamrut and three level of spacing were of Panchgavya (3% and 5%) and Jeevamrut (5% and 10%). The experiment was laid out in Randomized Block Design with twelve treatments each replicated thrice. Based on the objectives taken maximum plantheight (78.34 cm), number of total branches (4.76), plant dry weight (17.91 g/plant), seed yield (1.73 t/ha) and stover yield (3.45 t/ha) were recorded significantly higher in treatment combination of Panchagavya (5%) + Spacing 40 × 15 cm.number of pods per plant (22.99), number of seeds per pods (10.81) were recorded significantly higher in treatment combination of Panchagavya (3%) + Spacing 45 × 10 cm.
