Abstract: A field investigation entitled “Studies on combined influence of pruning and exogenous application of growth regulators on flowering and fruiting behaviour of Sweet Orange (Citrus sinensis Swingle.) cv. Sathgudi†was conducted at Fruit science block, sweet orange orchard, College of Horticulture, Anantharajupeta, Dr. Y.S.R.H.U. during the year of 2018-19. The experiment was laid out in factorial randomized block design with twelve treatments with single control and replicated thrice. A single tree was taken as treatment unit. Vegetative growth and flowering behaviors of the treated trees were studied to evaluate the combined influence of pruning and growth regulators. Among the different interaction treatments tested, to initiate flowering, in sweet orange (Citrus sinensis Swingle) cv. Sathgudi, Maximum shoot length was recorded in T4 (P1C4- Pruning 10 cm + GA3 @ 100 ppm) whereasT2 (P1C2 – Pruning 10 cm + NAA @ 100 ppm) recorded less number of days taken for flowering, more number of flowers per shoot, maximum flowering percentage and highest flower retention percentage.
