An experiment was conducted at Agronomy farm, S.K.N. College of Agriculture, Jobner, Jaipur during kharif, 2017. The experiment consisted 16 treatment combinations comprising of four levels each of phosphorus (0, 20, 40 and 60 kg P2O5 ha-1) and sulphur (0, 20, 40 and 60 kg S ha-1) was laid out in randomized block design and replicated thrice. Clusterbean variety RGC-1038 was used as a test crop. The results indicated that total chlorophyll content at 45 DAS, number of total and effective root nodules at flowering were observed significantly maximum upto 40 kg P2O5 ha-1 level of phosphorus application over control and 20 kg P2O5 ha-1. Whereas, the available N, P2O5 and S in soil after harvest of clusterbean were recorded significantly maximum with the application of 60 kg P2O5 ha-1. Application of sulphur upto 40 kg ha-1 resulted in significantly maximum increase in total chlorophyll content at 45 DAS, number of total and effective root nodules at flowering over control and 20 kg S ha-1. Where as, significantly maximum available N, P2O5 and S in soil after harvest was recorded with the application of 60 kg S ha-1. The optimum dose of phosphorus and sulphur as derived from response function curve were 49.31 and 50.64 kg ha-1 respectively.
