Effect of NAA and ga3 spray on quality parameters of strawberry (Fragaria x ananassa Duch.) cv. Sabrina under net tunnel

Abstract

The experiment entitled “Effect of NAA and GA3 on quality parameters of strawberry (Fragaria × ananassa Duch.) cv. Sabrina under net tunnel” was conducted at Research Farm of Centre of Excellence on Protected Cultivation and Precision Farming under net tunnel, College of Agriculture, IGKV, Raipur (C.G.) during the year 2017-18. The experiment was conducted with eleven treatments and three replications in Randomized Block Design (RBD). The treatment consisted eleven different concentrations of plant growth regulators along with recommended dose of fertilizers viz., T0: RDF + Control (Water spray), T1: RDF + GA3 25 ppm, T2: RDF + GA3 50 ppm, T3: RDF + GA3 75 ppm, T4: RDF + GA3 100 ppm, T5: RDF + GA3 125 ppm, T6: RDF + NAA 10 ppm, T7: RDF + NAA 20 ppm, T8: RDF + + NAA 30 ppm, T9: RDF + NAA 40 ppm, T10: RDF + NAA 50 ppm. The quality parameters of fruit in terms of total soluble solids (9.91%), TSS: acid ratio, total sugar (18.02), reducing sugar (5.71%), non-reducing sugar (3.21%) and ascorbic acid content (65.05 mg/100 g) was proved to be best showing a higher status with the treatment T3 (RDF + Gibberellic acid 75 ppm), while the acidity (0.55%) of fruit decreased by the application of same treatment.
