Effect of organic and inorganic fertilizers on yield of mustard.

Indian mustard cv. Pusa Bold was supplied with farmyard manure (FYM; 0 and 5 t FYM/ha), P (0, 40, 80 and 120 kg P2O5/ha) and S (0, 30 and 60 kg S/ha) in a field experiment conducted in Parbhani, Maharashtra, India during the rabi seasons of 1994/95-1995/96. FYM application increased the mean seed yield (by 7.83%), net returns (by 11.6%), oil (by 67 kg/ha), protein yield (by 53 kg/ha) and nutrient content. Total N, P and S uptake were also higher in FYM-treated vs. FYM-untreated plants, by 19.48, 3.99 and 3.55 kg/ha, respectively. An increase of 1.88 and 4.20 kg/ha available P and S, respectively, in the postharvest soil was also observed. The effects of 80 and 120 P2O5/ha applications were similar, and significantly increased seed and stover yields, net returns and oil and protein yields compared with the 0 and 40 P2O5/ha applications. Sulfur at 30 and 60 kg/ha resulted in higher seed and stover yields, and higher net returns. Increasing doses of S increased the oil and protein yield, N, P and S

 uptake, as well as the available P and S in the postharvest soil.
