ABSTRACT

A field experiment was conducted during rabi, 2022-23 on sandy clay loam soils dry land farm of S.V Agriculture College, Tirupati, Andhra Pradesh to study the “Organic nutrient management in fodder cowpea (Vigna unguiculata (L.)” The experiment was laid out in a split-plot design and replicated thrice. 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. Among the varieties tested, higher growth parameters i.e., (Plant height , leaf area index , number of branches plant1) and green fodder yield was recorded with MFC-09-01 (V₂). Among organic nutrient management practices tried, maximum growth and yield was observed with application of 75 % organic source through (FYM) + Rhizobium + PSB + KSB (F₃).
