Effect of Growth Regulators and Organics on Growth and Yield of Spiny Brinjal Variety VRM (Br) -1

Abstract

Two field experiments were carried out at Horticultural College, Kalavai to study the effect of growth regulators and organics on growth and yield of spiny brinjal (Solanum melongena) var.VRM-1. Growth regulators viz., Salicylic acid @ 200 ppm, Brassinosteriods  @ 0.1 ppm, Triacontanol @ 5 ppm and NAA @ 40 ppm and organics viz., Seaweed extract @ 1.0%, Humic acid @ 1.0%, Panchagavya @ 5.0% and Vermiwash @ 5.0% were tested and applied as foliar spray in spiny brinjal var VRM-1. Among the treatments tested, Panchagavya treatment recorded maximum value with regard to plant height (85.45 cm), leaf area (131.59 cm),  leaf area index (3.66), branches per plant (21.3 Nos) , flowers per plant (55.5 Nos), fruits per plant (20.9 Nos), fruit length (5.8 cm), fruit circumference (14.7 cm)  and individual fruit weight (82.1 g). Brassinosteroids treatment found to be effective in increasing root length (22.75 cm).
