Effect of growth regulators on germination and vigour of cow pea (Vigna unguiculata L. Walp.) seeds

Abstract

A study was conducted during 2016-17 to evaluate the effects of organic and inorganic growth regulators on germination and vigour of Cowpea (Vigna unguiculata L. Walp.) seeds at Graduate laboratory, Department of Agril. Botany, Govindraoji Nikam College of Agriculture, Mandki-Palvan, Ratnagiri (MS). The experiment consist of three concentrations of lemon juice (2, 4 and 6%), three concentrations of Coconut Water (2, 4 and 6%), three concentrations of GA3 (10, 20 and 30 ppm) and three concentrations of IAA (10, 20 and 30 ppm). The experiment was laid out in completely randomized block design with four replications. T8 (GA3 20ppm) proved significantly superior in germination per cent, germination index, shoot length, root length, seedling length, fresh weight of seedling, dry weight of seedling, seed vigour index-I, and seed vigour index-II.
