Abstract: A field experiment was conducted during the years 2011 and 2012 on okra cv. Parbhani Kranti to ascertain the influence of foliar application of plant growth regulators (PGRs) and nutrients with different concentrations on yield and its contributing characters. The field experiment was carried out at Horticulture Research Center of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut. The experiment consisted of two growth regulators and four nutrients in different concentrations. The different treatment concentration tested were NAA (25, 50 and 75ppm), GA3 (25, 50 and 75ppm), MnSO4 (2000 and 4000 ppm), FeSO4 (2000 and 4000 ppm), MgSO4 (2500 and 5000 ppm), CuSO4 (1000 and 2000 ppm) and Control (water spray). All variables parameters regarding yield attributes were significantly influenced by different concentrations of the growth regulators and nutrients. Results revealed that among all the treatments, the foliar application of GA3 (75 ppm) registered significantly higher reproductive aspects viz., number of flower per plant (22.88), number of pod per plant (20.68), fruit setting (90.34 %), pod length (20.63 cm), pod diameter (1.77 cm) and green pod yield (15.23 t/ha) over NAA and other treatments. While among the nutrients foliar application FeSO4 @ 4000 ppm had more positively effects on reproductive parameter as compare to other nutrient treatment.
