Abstract:
Field experiments were conducted to Studies effect of Phosphorus, Boron and Rhizobium inoculants on yield attributes and yield of chickpea during rabi season 2018-19 and 2019-20 at students instructional farm, Chandra Shekhar Azad University of Agriculture & Technology, Kanpur. The experiment comprised of eighteen treatments viz. T₁: P₀B₀, T₂: P₀B₁, T₃: P₀B₂, T₄: P₁B₀, T₅: P₁B₁, T₆: P₁B₂, T₇: P₂B₀, T₈: P₂B_I, T₉: P₂B₂, T₁₀: P₀B₀+Rhizobium, T₁₁: P₀B₁+Rhizobium, T₁₂: P₀B₂+Rhizobium, T₁₃:P₁B₀+Rhizobium, T₁₄:P₁B₁+Rhizobium,T₁₅: P₁B₂+Rhizobium,T₁₆:P₂B₀+Rhizobium,T₁₇ :P₂B₁ +Rhizobium, T₁₈: P₂B₂ +Rhizobium and replicated thrice. Results of the experiment reflected that yield attributes like of chickpea crop significantly increased with the use of phosphorus, boron and rhizobium inoculation. Maximum number of pods plant^-1 68.65, number of grains pods^-1 1.79, 100 grains weight 20.55 gm and harvest index 44.29% were recorded under T₁₈ ((P₉₀ +B₂ + rhizobium). The crop yield of chickpea significantly increased due to phosphorus and boron application @ 60 kg P₂O₅ ha^-1 and 1.0 kg ha^-1 respectively. Rhizobium inoculation significantly increased yield, both grain 18.52 q ha^-1 and stover 24.44 q ha^-1 recorded under T₁₄ (P₁B₁+Rhizobium)of chickpea crop during both the years of the experimentation. The maximum gross return Rs. (125546), net return Rs. (86846) and B:C ratio (2.24) were recorded under T₁₈ ((P₉₀ +B₂ + rhizobium). Combined application of phosphorus, boron and rhizobium inoculation. The present study showed that application of phosphorus, boron and rhizobium inoculation along with recommended nitrogen and potassium could be an effective option for enhancing chickpea yield attributes, yield and economic return.
