Abstract	Field trials were carried out at the ICAR Krishi Vigyan Kendra, Perambalur district, Tamil Nadu, during the Kharif seasons of 2022–2023 to evaluate the impact of foliar nutrient application on the phenotypic performance of cowpea variety CO 7. The experiment was structured using a Randomized Block Design (RBD) with three replications. Observations revealed that growth and yield parameters of cowpea, including plant height, leaf area index, dry matter accumulation, number of pods per plant, pod length, seeds per pod, and grain yield, were significantly improved with foliar application of 1% Pulse Wonder at 30 and 45 days after sowing (T2). In contrast, the control treatment (T1) exhibited the lowest values for these traits. The treatment involving Pulse Wonder spray (T2) also recorded superior physiological growth indices such as nodule number, nodule biomass, dry matter production, Absolute Growth Rate (AGR), Crop Growth Rate (CGR), and Leaf Area Duration (LAD) during the Kharif season.
