Abstract: A field experiment was conducted to study the influence of paclobutrazol on physiological aspects of pigeon pea (Cajanus cajan (L.) Millsp) under konkan conditions during Kharif, 2015 season. Plant growth regulators at different concentration were applied through foliar spray at 30, 40 and 60 DAS. The experiment consisted of thirteen treatment laid out in randomized block design with three replications comprising paclobutrazol (50, 75, 100, 125, 150 ppm) treatment imposed at 30, 40 and 60 DAS. Among the treatments soil application of paclobutrazol @ 50 ppm at 40 DAS recorded significant difference on morphological parameters as compared to other treatments. The plant height decreased significantly due to application of paclobutrazol and extent of reduction was more in the treatment soil application of paclobutrazol @ 50 ppm at 40 DAS. Growth period of the crop significantly reduced with the application of paclobutrazol. The number of days required for flower initiation, pod initiation and days to 50% flowering significantly reduced with the application of paclobutrazol. The maximum chlorophyll stability index was recorded in soil application of paclobutrazol @ 50 ppm at 40 DAS.The significantly highest relative water content was found infoliar application paclobutrazol @ 100 ppm at 30 and 60 DAS.
