Abstract
This study investigates bench grafting (BG) and field grafting (FG) in walnut by comparing the graft take rate, grade ratio, and simple earning rate using a conventional method. The mean grafting-take rate of the BG was 30.3% while that of FG was 77.1%. The quality of grafted seedlings is classified as good, fair, and poor. The quality grade ratio of FG seedlings is 3:4:3 (good:fair:poor) while the grade ratio of BG seedlings is 2:3:5. Field grafting resulted in 20% more good and fair seedlings than the BG method. As a result of calculating the earning rate with the sales income versus the input cost, FG has 1.5 times higher earning rate than BG. In summary, FG could be an alternative to conventional epicotyl grafting because it produced high-quality seedlings and increased productivity due to its high graft-take rate and earning rate.
