Abstract:
A field experiment was carried out to study the “Role of plant growth regulators on vegetative growth, yield and quality of sweet orange cv. Sathgudi at Horticulture Research Station, Konda Mallepally, Nalgonda Dist. during 2017 to 2019. Experimental findings revealed that, among the growth regulators, NAA 100 ppm recorded maximum plant height (303.33 cm), girth (47.0 cm), canopy spread North-South (362.67 cm), number of fruits/tree (324.67), average fruit weight (177.33 g), yield (57.00 kg/tree) and TSS (8.57 ºBrix) compared to control and other treatments. From the results, it can be concluded that of exogenous application of plant growth regulators like NAA and 2,4-D showed influence on sweet orange in growth, yield and quality.
