Abstract

An experiment was conducted at Lalbaug, Fruit Research Station, Department of Horticulture, College of Agriculture, Junagadh Agriculture University, Junagadh during the year of 2018. The experiment laid out in Completely Randomized Design with three replications. The treatments comprised of three different levels of time of sowing (S) viz., S1 – 15th April, S2 – 15th May; S3 – 15th June and six different levels of chemicals (M) viz., M1 – Control, M2 – GA3 200 ppm soaking for 24 hours, M3 – Concentrated H2SO4 0.1% soaking for 2 minutes, M4 – Concentrated HCl 0.1% soaking for 2 minutes, M5 – Cow dung and Cow urine slurry (1:2 ratio) soaking for 24 hours and M6 – Hot water (50 to 60˚C) soaking for 24 hours. The maximum height of seedling, stem girth, number of leaves, shoot length, root length, number of roots and fresh weight of shoot individually in 15th April sowing as well as in GA3 200 ppm treatment. That among different time of sowing dates, 15th April sowing treated along with GA3 200 ppm seed soaking for 24 hours found to be the most effective for higher leaf area, dry weight of shoot, fresh and dry weight of root.
