Abstract
The experiment was carried out at the research field and laboratory of Seed Technology Division during rabi season of 2013-14 to investigate the effect of different seed treatments on stand establishment, seed yield and quality of chickpea. Five seed treatments were: T1= GA3 50 ppm, T2= GA3 100 ppm, T3=GA3 200 ppm, T4= hydropriming and T5= Control. The maximum seedling emergence (78.00%) and plant population m-2 were obtained from GA3 50 ppm treatment which were at par with that of hydropriming. Remarkable variation was observed in CGR among the treatments at 60-120 days after emergence and maximum CGR was obtained from GA3 100 ppm and hydropriming treatments. Among the seed treatments, significant differences were recorded in plant height, number of branches plant-1, pods plant-1, seeds pod-1, 100-seed weight and seed yield. Seeds treated with GA3 100 ppm gave the highest seed yield followed by GA3 50 ppm and hydropriming. After harvesting, significantly highest seed germination (95.33%), root length (17.40 cm), seedling dry weight (66.43 mg) and vigour index (6338) were recorded from GA3 50 ppm which was at par with that of GA3 100 ppm.
Key words: Seed treatment, chickpea and hydropriming.
