Abstract
Sulphur is an important element in Indian soils, and it has been found as a major limitation for increasing the oil seed productivity. The results emerged out from experimental field showed that 100% NPK + FYM @ 5 t ha-1 recorded significantly maximum fractions of sulphur, namely organic sulphur (37.13 mg kg-1), non-sulphate sulphur (118.28 mg kg-1), water soluble sulphur (12.28 mg kg-1), heat soluble sulphur (1.45 mg kg-1) and total sulphur (153.65 mg kg-1) followed by only application of organic manuring as FYM @ 10 t ha-1. Different sulphur fractions exhibited negative correlation with pH and EC while, found positive significant with organic carbon, available N, P, K and S. Similarly, soybean and safflower both crops produced higher yields of grain (18.30 and 8.66 q ha-1) and straw (28.70 and 27.73 q ha-1), respectively. However, higher N (131.80 kg ha-1), P (26.27 kg ha-1), K (56.44 kg ha-1), S (15.43 kg ha-1) and Zn (253.90 g ha-1 ) uptake were observed by soybean whereas, N (54.43 kg ha-1), P(16.47 kg ha-1), K( 69.90 kg ha-1), S ( 11.29 kg ha-1 ) and Zn (162.19 g ha-1) were observed by safflower in application of 100 % NPK + FYM @ 5 t ha-1.
