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.
