EFFECT OF GA3 AND NAA ON GROWTH AND QUALITY OF ALITY OF GARDEN PEA (PISUM SATIVUM L.) CV. ARKEL

Abstract

The experiment was conducted during rabi season 2014-2015 in pots at the Department of Biological Sciences, SHIATS, Allahabad to study the effect of GA3 (50, 100, 150, 200 ppm) and NAA (15, 25, 35, 45 ppm) on Garden pea (Pisum sativum L.). The plant growth regulators were applied as foliar application at 15 and 45 days after sowing. Looking to the result, it was noticed that the morphological and yield characters showed significant increments with the foliar spray of 200 ppm gibberellic acid (GA3 ) plant height (41 cm), number of leaves (36.6/ plant), number of branches (8.2/plant), flower at 50 DAS (8.2/plant), number of pods (14.7/plant), number of seed (8.5/pod), pod length (8.8 cm), 100 seed weight (24.8 g). The physiological character was significantly increase chlorophyll a (1.914 mg/g) and b (1.983mg/g), total chlorophyll (3.894 mg/g fresh weight) and caroteinod (3.293 mg/g fresh weight) and the quality character like protein (245 mg/g) and carbohydrate (643 mg/g) as compared to control. Therefore it may be concluded that foliar application of GA3 at 200 ppm can be recommended to Garden pea grower for obtaining better growth and yield of Garden pea.
