Description There is large number of sulphur(S) sources available in the country and their efficiency need to be evaluated. In view of the meager information available on sulphur nutrition in a popular intercropping system of pigeonpea + groundnut. A field experiment was conducted during kharif 2003 and 2004 to evaluate the response of pigeonpea [Cajanus cajan (L.) Millsp.] + groundnut (Arachis hypogaea L.) intercropping system to FYM and S fertilization. Application of FYM at 5.0 t/ha significantly increased the yield and yield attributes, nutrient (NPK) uptake in pigeonpea and groundnut, system productivity (1.71 t/ha), net returns (Rs 18,287) and available S in soil after harvest (15.72 kg/ha). However, B: C ratio was higher with crop receiving no FYM. Intercropping failed to influence the yield attributes, yield and nutrient uptake in pigeonpea, however, system productivity, net income and B: C ratio was higher in pigeonpea + groundnut system. The available soil S after harvest of crop(s) was lower in pigeonpea + groundnut system (13.11 kg/ha) when compared with sole pigeonpea (17.06 kg/ha). Application of sulphur at 35 and 70 kg/ha, being on par, recorded significant increase in yield and nutrient uptake in pigeonpea and groundnut, system productivity and total net income over no S. The available soil S after harvest of crop (s) was higher with 70 kg S/ha. The S use efficiency indices were higher at lower i.e. 35 kg S/ha. Among the sources of sulphur, cosavet recorded higher yield and yield attributes, nutrient uptake and S use efficiency. However, the highest soil available S at harvest (19.34 kg/ha) was recorded with elemental S applied at 70 kg/ha, while the highest net income (Rs 20,431) and B: C ratio (2.0) were achieved with gypsum at 35 kg S/ha.
