Study on effect of plant growth regulators and boron on quality attributes of tomato (Solanum lycopersicum MILL.)

Abstract

The field experiment was conducted during Rabi season of 2017-18 at the Horticulture Research cum Instructional farm, BTC CARS, Bilaspur (C.G.). The experiment was laid out in Randomized Block Design (RBD) replicated thrice including ten treatments viz., treatments T1 (control), T2 (GA3 @ 50 ppm), T3 (GA3 @ 75 ppm), T4 (NAA @ 75 ppm), T5 (NAA @ 100 ppm) T6 (Boron @ 75 ppm), T7 (GA3 @ 50 ppm + Boron @ 75 ppm), T8 (GA3 @ 75 ppm + Boron @ 75 ppm), T9 (NAA @ 75 ppm + Boron @ 75 ppm) and T10 (NAA @ 100 ppm + Boron @ 75 ppm). The significantly Maximum total soluble solid (5.06 %) was recorded in (T10), while, the minimum total soluble solid (3.53 %) was observed in (T1). The highest ascorbic acid recorded (30.00 mg/100 g) in (T8), whereas, lowest ascorbic acid observed by (T1). And Lowest percentage of acidity (0.45 %) was recorded in (T10) and highest percentage of acidity (0.60 %) was observed in (T1).
