The present investigation entitled “The effect of foliar feeding of plant growth regulators on physico-chemical attributes of phalsa (Grewia subinaequalis D.C.)” was conducted at Main Experiment Station, Horticulture, Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad, Uttar Pradesh during 2014-2015 in Randomized Block Design and replication three and ten treatments T1 - Control (Water spray), T2-GA3 50 ppm, T3-GA3 100 ppm,T4-GA3 150 ppm,T5-NAA 50 ppm,T6-NAA 100 ppm,T7 –NAA 150 ppm, T8 Ethrel 50 ppm, ethrel T9 100 ppm, ethrel T10 150 ppm. Physico-chemical characters like as fruit length & width, weight of 50 fruits, pulp-stone ratio, ascorbic acid content, etc. were increased and acidity per cent was reduced with the application of GA3 @ 150 ppm, however total soluble solids and sugars (reducing, non-reducing, total sugar) content were improved by ethrel 100 ppm amd it is also effective in reducing acidity. It is clear from the data foliar application of GA3@150 ppm effective to increase vegetative growth, yield and quality parameter respectively and ethrel@100 ppm was found best in quality improvement in phalsa fruits. A wider research has been done in the use of plant growth regulators and it is very effective in all fruits crops specially subtropical and tropical fruit crops. Hence plant growth regulators are very effective in improving physico-chemical attributes or quality of phalsa fruits.
