Walnut is one of the temperate zone fruit crops. It is deciduous and belongs to the family of Juglandacea. This fruit has special place due to its nutritive nut and valuable wood.
Walnut grafting or budding has gained high importance to propagate specific high value and commercial cultivars. To propagate walnut, different grafting methods have been done during winter time and budding has been tried during spring and summer time. This research work done within two separate experiments. In first experiment, effects of time of grafting, type of bed and grafting methods were studied. How ever, in second experiment, effects of patch budding time, removing of leaf blade on scion shoots two weeks before and wound making on rootstock three weeks before bidding were studied. Results showed that kind of bed (hot bed against normal bed) had no significant effect to final grafting success five month after grafting. Side grafting was more successful than saddle grafting and time of grafting had highly significant effect on grafting success. Among different time of grafting (6.11.78, 6.12.78 & 23.12.78), time of 6.11.78 was much more successful.
Results of second experiment, was very interesting. In this experiment, effect of time of doing patch budding was highly important in final budding success even after nine month of budding, in which the highest rate of success among certain times (4.4.79, 16.4.79, 30.4.79, 20.6.79, 30.6.79, 10.7.79 & 20.7.79), the time of 20.6.79 was more effective. Removing leaf blade of scion shoots two weeks before and wound making on rootstock at three weeks before doing patch budding and positive effect but it did not reach significant level. In general, patch budding is more advisable due to its low requirement to facilities and is more commercial.
