dc.description.abstractAn experiment was conducted under field conditions during kharif 2021 at CCS HAU, Regional Research Station, Bawal to study the “Performance of clusterbean (Cyamopsis tetragonoloba L.) as influenced by potassium levels and foliar application of nutrients under irrigated conditions.” The experiment was laid out in a randomized block design with thrice replications and treatments comprised three levels of potassium (0, 20 and 30 kg K2O ha-1) and foliar spray of 2% urea along with 2% multiplex nutrient at pre-flowering and pod formation stage with basal application of RDF [20:40:00 kg ha-1 (N: P2O5:K2O)]. The results showed that the number of nodules and their fresh weight was increased significantly with the application of potassium and foliar spray of 2 % urea and 2% multiplex nutrient at pre-flowering and pod formation stage. Seed and stover yield increased with the increase potassium and foliar spray of 2 % urea and 2% multiplex nutrient at pre-flowering and pod formation stage over control. The quality parameters like as protein content and gum content significantly increased with the application of potassium up to 30 kg K2O ha-1 with foliar spray. N, P, K and S content in seed and stover was significantly increased with the application of potassium and foliar spray but Ca and Mg content in seed and stover decrease with increase in potassium level. Uptake of N, P, K and S nutrients in seed and stover significantly increased with the application of potassium and foliar spray of 2 % urea and 2% multiplex nutrient but uptake of Ca and Mg decrease with increase in potassium level. Soil properties like pH, EC and organic carbon reported no significant influenced with the levels of potassium and foliar spray. Available N, P, K, S and different forms of K (water soluble K, exchangeable K, non-exchangeable K and total K) of soil after crop harvest was increased significantly while, Ca and Mg decreased significantly with the potassium application. Overall soil fertility was also found to be improved due to the application of potassium and foliar spray of urea and multiplex nutrient in clusterbean at pre-flowering and pod formation stage. The higher net monetary returns (Rs. 102240 ha-1) with B:C ratio (1.82) obtained under the treatment T9 (30 kg K2O ha-1 + 2% Urea spray+ 2% Multiplex nutrient spray). It is concluded that application of 30 kg K2O ha-1 at sowing and foliar spraying of 2% urea along with 2% multiplex at pre-flowering and pod formation stage was found to be suitable to improve soil conditions and to achieve optimum grain yield, monetary returns in clusterbean.en_US
