In a study conducted at College of Agriculture, University of Agricultural Sciences, Dharwad, India. Effect of foliar spray of naphthalene acetic acid [NAA] (50, 100 and 150 ppm) and mepiquat chloride [MC] (500, 1000 and 1500) at 45 and 65 days after transplanting (DAT) on yield, physiological and biochemical parameters of bell pepper (Capsium annuum, cv. Tarihal Local) was studied. All treatments significantly increased fruit yield, number of fruits, average fruit weight and number of seeds. Total chlorophyll, ascorbic acid and nitrate reductase activity were also increased. Fruit yield was significantly high (159.89 g/plant) with double spray of MC @ 150 ppm at 45 DAT and at 65 DAT followed by MC @ 1500 ppm at 45 DAT (156.49 g/plant) compared to control. From economic point of view, single spray of MC @ 500 ppm at 45 DAT wasmore profitable compared to other treatments.
