Abstract: An on-site investigation carried out at the Cotton Research Station, Junagadh Agricultural University, Junagadh during the kharif season in 2021 intended to explore the influence of foliar application of cow urine and NAA on various parameters related to the morpho-physiological, biochemical, and yield aspects of kharif sweet corn. The study employed a randomized block design with a factorial concept, incorporating different concentrations of cow urine (control, 2%, 4%, and 6%) and NAA (control, 15 ppm, and 30 ppm), and three replications. The research focused on assessing growth parameters such as AGR, CGR, RGR, and NAR factors. The findings indicated that the treatment involving 4% cow urine and 15 ppm NAA exhibited the highest mean values for growth characters AGR, CGR, RGR, and NAR. The positive effects observed are attributed to the additional nutrients supplied through the foliar application of cow urine, potentially enhancing chlorophyll synthesis in the sweet corn crop.
