Abstract
The present investigation entitled “Studies on different methods and time of grafting in walnut (Juglans regia L.) under different growing conditions” was carried out in Fruit Nursery, College of Horticulture, V. C. S. G. Uttarakhand University of Horticulture and Forestry, Bharsar, during 2015- 2016. In this study the scion of Govind variety were grafted on walnut seedling with different methods and time of grafting under different growing conditions with Factorial Randomized Complete Block Design and three replications. The different parameters for this methods, conditions and time were recorded to evaluated the best methods of grafting under different growing conditions at different time. In the present study cleft grafting under polyhouse conditions during February (G2P1T2) with minimum days taken to sprouting, maximum number of leaves per graft, total number of branch per grafted plants, minimum dead graft, maximum saleable plants, maximum survival plants, maximum shoot length, maximum shoot diameter and maximum leaf area (i.e., 40.38 days, 114.47, 16.60, 40.38%, 91.40%, 38.87%, 68.49cm and 31.75cm2 respectively) show the best performance. The minimum dead graft after sprout 15.46% was recorded in veneer grafting under polyhouse during February (G3P1T2). Hence, the different methods of grafting under different growing conditions at different time varied in their growth characteristics. The cleft grafting under polyhouse conditions during February (G2P1T2) was the best combination of methods, condition and time where healthy walnut plants with good growth were observed.
