Effect of Plant Growth Regulators on Fruit Yield and Quality of Guava (Psidium guajava) cv. Allahabad Safeda

Year: 2017

Type: article

Abstract: Pre-harvest foliar application of growth promoters like NAA (Naphthalene Acetic Acid), GA3 (Gibberellic Acid) and Triacontanol can be effectively used to improve yield and quality attributes of guava fruits. NAA (100-200 ppm), GA3 (25-75 ppm) and Triacontanol (5-15 ppm) applications were reported to bring improvement in yield and quality of guava fruits in comparison to control. The results of experiment revealed that foliar application of NAA 200 ppm recorded maximum fruit size (53.14cm2), fruit weight (138.53gm), specific gravity (1.17gm/cm3) and minimum seed weight (5.19gm) followed by NAA 150 ppm. The quality of fruits in terms of total soluble solids (11.47%), reducing sugar (4.48%), ascorbic acid (239.03g/100gpulp) and total sugar (7.43%) were also significantly higher with treatment NAA 200 ppm followed by NAA 150 ppm. Moreover, an application of NAA 200 ppm significantly reduced acidity (0.20%).
