Abstract:
A field experiment was conducted during Rabi season of 2020-21 at Tirhut College of Agriculture Farm, Dholi (Muzaffarpur), Dr. Rajendra Prasad Central Agricultural University, Pusa (Samastipur), Bihar, in order to explore the possibility of improving the yield and economics of both potato and maize crops by the use of integrated nutrient management under potato + maize intercropping system. Potato was intercropped with maize (1:1), having 100 percent population of both the crops. The results obtained after statistical analysis of data revealed that the potato tuber yield (t/ha), vine yield, biomass yield, maize grain yield, stover yield, stone yield and biomass yield showed the beneficial effect from the use of integrated levels of NPK and FYM. The treatment T₁₄ (125% RDF of potato + 125% RDF of maize + 20 t FYM ha^-1) gave higher yield and better B:C in intercropping system, it was also found to give higher yield in terms of potato equivalent yield. T₁₄ was found to be at par with T₁₀ (RDF of potato + 100% RDF of maize + 20 t FYM ha^-1), T₁₂ (RDF of potato + 125% RDF of maize + 20 t FYM ha^-1) and T₁₃ (125% RDF of potato + 125% RDF of maize + 10 t FYM ha^-1) in terms of both yield and economics.
