A field experiment was conducted during Kharif 2015 at cotton research station, Sirsa, CCS HAU, Hisar (India). The experiment was conducted in RBD with three replications. The experiment consist of 16 treatments in which N and P were applied as per recommended dose (N= 20 kg/ha, P2O5= 40 kg/ha) along with different doses of Zn (10, 20 and 30 kg/ha) and S (20, 30 and 40 kg/ha) and their combinations. Growth parameters viz. plant population, plant height and dry matter accumulation were recorded maximum in T16 (N @ 20 kg + P2O5 @ 40 kg+ ZnSO4 @ 30 kg + S @ 40 kg/ha). Yield attributes viz. no. of pods/plant, no. of grains/pod, Yield viz. grain and straw yield were also recorded highest in T16, while maximum harvest index was observed in T8 (N @ 20 kg + P2O5 @ 40 kg+ ZnSO4 @10 kg + S @ 20 kg/ha) and highest 1000 grains weight (test weight) was observed in T13 (N @ 20 kg + P2O5 @ 40 kg+ ZnSO4 @ 20 kg + S @ 40 kg/ha) as compared to other nutrient treatments. In clusterbean, cost of cultivation and gross returns were recorded highest in T16, while T10 recorded highest net returns and B: C than other nutrient treatments. All the parameters were recorded lowest in control treatments. It may be concluded that T16 resulted in better growth parameters, yield attributes, yield and economics except harvest index higher in T8, and net returns higher in T10. Increased in growth and yield parameter was observed, further study can be explored to optimize the nutrient requirement for yield maximization, profitability and sustainability.
