Effect of Organic Nutrient Management on Quality Parameters and Yield of Fodder Cowpea Varieties

Abstract

The field experiment was conducted during Rabi season of, 2022–2023 on sandy clay loam soils at a dry land farm in the S.V. Agricultural College in Tirupati, Andhra Pradesh, India. To study the Effect of organic nutrient management on quality parameters and yield of fodder cowpea The Split-plot design of the study included three replications. The treatments consisted of four varieties viz., V1: Vijaya, V2: MFC-09-01, V3: MFC-09-03, and V4: MFC-08-14 assigned to main plots, four organic nutrient management practices viz., F1: Control, F2 : 100 % organic source through (FYM) F3: 75 % organic source through (FYM) + Rhizobium + PSB + KSB and F4: 50 % organic source through (FYM) + Rhizobium + PSB + KSB allotted to sub plots. The soil was neutral in reaction (6.8 pH) low in available nitrogen (176 kg ha-1) and medium in available phosphorus (27 kg ha-1) and low in available potassium (219 kg ha-1) status.). The results revealed that among the varieties tested, higher quality parameters i.e., (Crude protein content , Total ash content and dry fodder yield) was recorded with MFC-09-01 (V2) and dry fodder yield (5.8 t ha-1) as well as crude protein (15.1 %), ash content (12.5 % ) were obtained with the application of 75 % organic source through (FYM) + Rhizobium + PSB + KSB. Furthermore, compared to all other treatments.
