Effect of foliar application of nutrient sources on fruit quality of sapota cv. Kalipatti

The present experiment was conducted during the year 2019-20 and 2020-21 at Instructional Farm, ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari. The experiment was laid out in Completely Randomized Design with three repetition and eight treatments. Among the different treatments, foliar spray of T8 [Ca(NO3)2 @ 0.6% + Boric acid @ 0.2% + NOVEL+ @ 1.5%] was found better with respect to maximum TSS (21.03, 21.33 and 21.18 °Brix), ascorbic acid (18.97, 19.37 and 19.17 mg/100g), total sugars (18.23, 18.94 and 18.58%), reducing sugar (9.93, 10.33 and 10.13%), non-reducing sugar (8.30, 8.60 and 8.45%), shelf life (9.87, 10.07 and 9.97 days), organoleptic evaluation score and lower titrable acidity (0.109, 0.111 and 0.110%) during the year 2019-20, 2020-21 and pooled data, respectively.
