Field experiments were conducted at two different locations (Barani Agricultural Research Institute Chakwal & farmer's field Talagang, district Chakwal) in northern rainfed Punjab, Pakistan to assess the yield and micronutrient uptake of chickpea (Cicer arietinum L.). The treatments comprised of three levels (0, 40 & 80 kg P(2)O(5) ha(-1)) of phosphorus (P) and three levels (0, 15 & 30 kg ha(-1)) of sulfur (S) in different combinations. Application of P and S resulted in significant increase in grain yield ranging from 22 to 35% and 10 to 16% over control, respectively. Effect of P and S application was synergistic at all P and S levels at Barani Agriculture Research Institute (BARI) Chakwal, while at farmer's field Talagang, it was synergistic at lower level of P application (40 kg ha(-1)) and antagonistic at higher level of P (80 kg ha(-1)). Lower level of P application (40 kg ha(-1)) resulted in increase in zinc (Zn) uptake by 23 to 25% over control and higher rate (80 kg ha(-1)) caused decline in Zn uptake. Almost similar observations were recorded regarding effect of S application on Zn uptake in both grain and straw. Both P and S application resulted in increase in copper (Cu) uptake by 40 to 62% and 16 and 59%, respectively. There was 21 to 74 and 19 to 70% increase in iron (Fe) uptake with application of P and S, respectively. Corresponding figure for manganese (Mn) uptake was in range of 17 to 34% for P and 14 to 42% for S.
