An experiment was conducted to know the effect of foliar application of chitosan with different concentrations and number of applications (once, twice and three times) on quality and biochemical traits of strawberry (var. Winter Dawn) during 2019-2020. Among the treatments tested,Chitosan spray 3 g l-1 at 45, 90 and 135 DAP recorded comparatively better biochemical traits of fruit viz., Total Soluble Solids (7.96 Brix), chlorophyll-a (1.85 mg g-1), chlorophyll-b (0.59 mg g-1)and decreased physiological loss in weight (PLW) (3.45 %). On the contrary, Chitosan spray 2 g l-1 at 45, 90 and 135 DAP recorded maximum reducing sugar (4.79 %), non-reducing sugar (1.65 %), total sugar (6.44 %) and antioxidants (413.42 µg BHT g-1fruit). While the ascorbic acid (53.29 mg 100 g-1) and anthocyanin content (54.69 mg 100 g-1) found maximum in Chitosan spray 3 g l-1 at 45 DAP with minimum titratable acidity (0.86 %). From this study, it was concluded that foliar application of chitosan thrice at 3 g l-1 with 45 days interval was found better (fruit yield per plant 366.17 g) followed by foliar application of chitosan thrice at 2 g l-1.
