Abstract: The present experiment was carried out at Dryland Horticulture Farm, Sirsod, Department of Horticulture, College of Agriculture, Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya, Gwalior (M.P.). The experiment was laid out in Complete Randomized Design (CRD) with eight treatments and three replications. All the treatments were randomized within whole experiment at once. Observations of the characters under study of drumstick plants were recorded. The five randomly selected plants from each treatment for observations were undertaken. The data was recorded as per the standard procedure and analyzed statistically as per design. Days taken to first seedling emergence were counted. It was recorded daily when the first foliage leaf appeared. Germination was visually monitored through the counting of germinated seedlings after every seven days and then was finalized at 25 days. The minimum days taken to germination (4.28) was taken under seed soaked in the solution of 10ppm GA3 for 24 hours (T4) followed by seed soaked in 10ppm GA3 solution for 48 hours (T8) (4.72), seed soaked in 7.5ppm GA3 for 24 hours (T3) (4.88), seed soaked in 7.5ppm GA3 for 48 hours (T7) (5.08) while maximum days for emergence (5.91) was taken by seed soaked in normal water for 48 hours (T5) followed by seed soaked in normal water for 24 hours (T1) (5.85), which was at par with each other. There was no significant difference recorded between seed soaked in 5ppm GA3 concentration for 24 and 48 hours. Results also indicated that the seed soaked in different concentrations of GA3 for 24 hours was found superior over seed soaked in the same concentrations of GA3 for 48 hours. The days taken to 50% germination were significantly influenced with different treatments. Minimum days (5.88) taken to 50% germination were counted with seed soaked in 10ppm GA3 for 24 hours (T4) followed by seed soaked in 10ppm GA3 for 48 hours (T8) (5.92), seed soaked in 7.5ppm GA3 for 24 (T3) and 48 hours (T7) (6.27 and 6.38), respectively. However, there was no significant difference between seed soaked in 10ppm GA3 for 24 and 48 hours. Maximum days taken to 50% germination were counted with seed soaked in normal water for 48 (T5) and 24 hours (T1) (8.33 and 8.17), respectively which was at par with each other. the different seed soaking treatments were significantly affected to germination percentage of drumstick. The seed soaked in 10ppm GA3 solution for 24 hours (T4) was exhibited maximum germination percentage (70.83%) followed by seed soaked in 10ppm GA3 for 48 hours (T8) (67.12%) and seed soaked in 7.5ppm GA3 solution for 24 hours (T3) (66.82%) which was at par with each other. Whereas, minimum germination percentage (52.32%) was noted with seed soaked in normal water for 48 hours (T5) followed by seed soaked in normal water for 24 hours (T1) (55.77%).
