The results indicated that, the application of RDF + 30 kg K2O ha-1 +25 kg ZnSO4 ha-1 improved growth, quality parameters and increased grain and straw yield. Soil fertility status (available N, P, K, and S), micronutrients and plant nutrient concentration were higher in the treatments receiving potassium and zinc supplementation. The total uptake of nutrients was significantly increased with application of potassium and zinc @; RDF + 30 kg K2O ha-1 and RDF + 30 kg K2O ha-1 +25 kg ZnSO4 ha-1. The uptake of N, P, K and zinc was increased due to K application and maximum uptake of these nutrients was noticed in the treatments receiving K and Zn in combinations. Available N and P status at various growth stages of chickpea were found to be increased at pod development stage and thereafter, N and P available status was decreased. The plant nutrient concentration studied in the present investigation was enhanced due to K and Zn application over absolute control. Thus, the maximum gross monetary returns, net monetary returns and monetary benefits were observed in treatment receiving RDF + 30 kg K2O ha-1 +25 kg ZnSO4 ha-1 with 1.74 B: C ratio. These findings indicate requirement of K and Zn to chickpea.
