Abstract:
The field experiment was conducted at agriculture research farm of S.D.J Post Graduate College Chandeshwar, Azamgarh, (U.P.) during 2005-06 and 2006-07. The experiment laid out in Randomized Block Design (RBD) with nine treatment combination viz., three soil treatments in main plot [Control (C₀), Gypsum @ 100 kg/ha (C₁)_, FYM @ 5 t/ha (C₂) ] and six chemical fertilizer treatments in sub plot [Black gram; F₁-100% Recommended (N₂₀P₄₀K₂₀), F₂- 75% of recommended (N₁₅P₃₀K₁₅), F₃-50% of recommended (N₁₀P₂₀K₁₀) & Wheat; F₁-100% Recommended (N₁₂₀P₆₀k₄₀)_, F₂-75% of Recommended (N₉₀P₄₅K₃₀), F₃-50% of recommended (N₆₀P₃₀K₂₀)],total number of plots were 36 along with four replications. The result indicates that significantly higher grain yield (pooled 2005-06, 2006-07); Stover yield (2005-06, 2006-07) and biological yield (2005-06, 2006-07) and harvest index (2005-06, 2006-07) were recorded with the application of soil test based FYM @ 5t ha^-1 [C₂]and in 100% Recommended (N₂₀P₄₀K₂₀)[ F₁]. Growth parameters were also found higher with the application of 5 t hac^-1 FYM and with 100% recommended dose of chemical fertilizer as compare to other treatments. With regards to economics, soil test based application of 5t FYM ha^-1 resulted in highest gross returns (Rs. 16591 ha^-1), net returns (3251 ha^-1) and benefit: cost ratio (1.25) over other nutritional treatments. Similarly, in chemical fertilizer treatments the100% Recommended (N₂₀P₄₀K₂₀) obtained the highest gross return (Rs. 16510 ha^-1), net return (Rs.2661 ha^-1) and benefit cost ratio (1.27) among the other treatment respectively.
