Phosphorus-sulphur interaction was studied in a field experiment at Agricultural Research Station, Durgapura, Jaipur on a loamy sand soil (Typic Ustipsamment) deficient in S and medium in P-with chickpea (Cicer arietinum L.) as a test crop. The treatments consisted of three levels of S (0, 15 and 30 kg ha-l) and four levels of P (0, 20, 40 and 60 kg P20sha-l) applied through gypsum and triple superphosphate, respectively. Result~ndicated that grain and straw yield; content of N, P and S; and uptake of P and S increased with increase in rate of application of P and S individually as well as in various combinations. Applied Sand P increased the number of nodules plantl and protein content in grain. Available P in soil increased with increasing levels of phosphorus. Similarly available S in the soil increased with increasing levels of sulphur. The synergistic effect of phosphorus and sulphur was observed on yield, number of nodules plant-l, protein content and uptake of Sand P.
