Abstract
A field experiment was planned and conducted during Rabi 2015-16 to evaluate the “Studies on use of potassium and zinc on yield and nutrient uptake by chickpea”. The experiment was conducted the Departmental Research Farm of Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani. The experiment was laid out in Randomized Block Design with three replications. There were eight treatments comprising of K and zinc levels viz ; T1- Absolute control, T2- Only RDF through soil (25:50:00 NPK kg ha-1), T3 –RDF + 15 kg K2O ha-1, T4- RDF + 30 kg K2O ha-1, T5- RDF+45 kg K2O ha-1, T6- RDF+15 kg K2O ha-1+25 kg ZnSO4 ha-1, T7- RDF + 30 kg K2O ha-1 + 25 kg ZnSO4 ha-1, T8- RDF + 45 kg K2O ha-1 + 25 kg ZnSO4 ha-1. The results indicated that, the application of RDF + 30 kg K2O ha-1 +25 kg ZnSO4 ha-1 improved growth, 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 were 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 were 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. Potassium availability was decreased from flowering to harvesting stage, and sulfur availability increased till the harvesting. In respect of micronutrients, no specific trend was noted. However, the application of zinc to chickpea maintained the higher Zn availability throughout the crop growth period. 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.
