Abstract: A field experiment was conducted during kharif season of 2018 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj to study the growth of Blackgram (Vigna mungo L.) as influenced by foliar application of nutrients and plant growth regulators. The experiment comprised of Randomized Block Design with three replications and nine treatments. It consisted of foliar applied Urea at 2% and Micronutrient mixture (Zn, Fe, B and Mo) at 0.5% and Plant growth regulators such as NAA at 40 ppm, Brassinolide at 0.25 ppm, Salicylic acid at 50 ppm and Gibberellic acid at 50 ppm spraying at 25DAS and 45DAS. It was observed that the combination of Recommended Dose of Fertilizers (25-50-25kg N-P-K/ha), Urea at 2% and NAA at 40 ppm (T₁) was proved to be the best treatment for obtaining higher growth attributes such as Plant height (63.63 cm), No. of Branches (31.13), Root nodules (23.73), Plant dry weight (51.71 g), and higher Protein content (31.50%) was obtained in Blackgram variety ‘T-9 (improved)’ as compared to other treatments.
