Influence of Foliar Application of Plant Growth Regulators and Nutrients on Physical Fruit Characteristics of Seedless Jamun (Syzygium cumini L.)

Abstract

Jamun is an important minor fruit crop of tropical and subtropical countries and widely distributed throughout India. It is a versatile tree for both food and medicinal values. A local type seedless jamun trees which were located at Regional Horticultural Research and Extension Centre (RHREC), College of Horticulture, Bengaluru, evaluated to examine the influence of plant growth regulators and nutrient on physical characteristics. Significant differences were observed in physical characteristics among the various foliar application treatments. The maximum length of the inflorescence (9.79 cm) and breadth of the inflorescence (9.11 cm), lowest flower to fruit set duration (39.00 days) was recorded on foliar application of humic acid (0.2 %). The maximum fruit set per panicle (6.40) and fruit set percentage per panicle (87.16 %), fruit weight (2.31 g), fruit pulp weight (1.96 g), fruit length (19.57 mm), fruit diameter (12.99 mm), lowest number of fruits (509.66 fruits / kg) and maximum yield (25.21 kg / plant) was recorded in foliar application of GA3 at (50 ppm).
