Abstract: To study the effect of phosphorus, sulphur and irrigation on mustard + chickpea intercropping system, a field experiment was conducted at A.S. (P.G.) College, Lakhaoti, Bulandshahr, (U.P.) during rabi season of 2009-2010 and 2010-2011. The experiment was carried out in split plot design with three replications. The treatments consisted of four levels (no irrigation, one irrigation at pre-flowering, one irrigation at grain filling and two irrigations one each at pre-flowering and grain filling stage of mustard) of irrigation in main plots, and three levels (0, 30 and 60 kg P2O5 ha-1) of phosphorus and three levels (0, 20 and 40 kg S ha-1) of sulphur in sub-plots. The results showed that in both the years of experimentation, application of two irrigations significantly increased number of primary and secondary branches plant-1 over other levels of irrigation, which resulted in significantly higher grain and biological yield with two irrigations as compared to one irrigation in mustard + chickpea intercropping. Application of 60 kg P2O5 ha-1 produced more number of primary branches than control during both the years of study. Application of 40 kg S ha-1 produced more number of primary and secondary branches plant-1 than control during both the years of study. Biological yield of mustard and chickpea increased significantly with the successive increase in the level of applied phosphorus and sulphur in both the years. NPS content in stover and grain of mustard and chickpea and NPS uptake increased significantly with increasing level of phosphorus, sulphur and irrigation.
