Abstract:

An experiment was conducted to study the effect of different growth regulators on yield and quality of sweet orange cv. Jaffa at Research Orchard of Department of Horticulture, Chaudhary Charan Singh Haryana Agricultural University, Hisar, India during the year 2015-16. Plants were treated with GA3, 2,4-D and NAA in different concentrations was sprayed twice, i.e., in last week of March and first week of July and control (distilled water) yield and physico-chemical changes was observed at regular intervals. The experimental design was randomized block design (RBD) and each treatment was replicated four times. Experimental findings revealed that, among the growth regulators NAA 20 ppm recorded with highest number of fruits per plant and fruit yield per plant than other treatments. It was observed that quality parameters such as TSS (ºBrix) (9.87), TSS to acid ratio (15.10), Ascorbic acid (51.44 mg/100 ml) was found to be more in 2,4-D- 15 ppm followed by NAA- 30 ppm. It proved the effectiveness of growth regulators in increasing yield and quality of sweet orange.
