Abstract
The present investigation was conducted at Research Farm, Horticulture Section, College of Agriculture, Dhule to identify the effect of different combinations of growth regulators and chemicals on morphological characteristics of khirni. Khirni seedlings were grown and effect on them was studied for chemical combinations such as GA3 @ 50 ppm, GA3 @ 75 ppm, GA3 @ 100 ppm, GA3 @ 200 ppm, NAA @ 100 ppm, KNO3 @ 1 %, Cow urine @ 10 %, Cow urine @ 100 %, Cow dung slurry, and Control (Distilled water). Based on the findings, it is advised that khirni seedlings be treated with cow dung slurry for 36 hours in order to prepare them for grafting. This experiment should be carried out for a further two to three seasons in order to ensure compliance. With the highest 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 seedlings, the seed soaked in cow dung slurry (T9) was deemed promising based on the overall results.
