The experiment, laid out in complete randomized block design (CRBD) and three replications with ten treatments viz., GA3 @ 50 ppm, GA3 @ 75 ppm, GA3 @ 100 ppm, GA3 @ 200 ppm, NAA @ 100 ppm, KNO3 @ 1 per cent, cow urine @ 10 per cent, cow urine @ 100 per cent, cow dung slurry, and control (Distilled water) at Research Farm, Horticulture Section, College of Agriculture, Dhule, in the Maharashtra state (India) with the objective of enhancing rooting characteristics in khirni, suggested that the seed soaked in cow dung slurry (T9) was the most promising. It had maximum average fresh root weight, maximum average fresh shoot weight, maximum root: shoot ratio (fresh weight basis), higher average root length and maximum root density of khirni seedling. It is advised that khirni seedlings be treated with cow dung slurry for 36 hours to prepare them for grafting when they are being raised for sapota grafting.
