Vegetative propagation in cashew - review of work done at Vittal

, : Vegetative propagation in cashew - review of work done at Vittal. Acta Horticulturae (108): 57-63

The different methods of vegetative propagation tried during 1977-78 were: (i) veneer grafting on 6-month-old seedlings raised in polybags, (ii) side-grafting on 3- to 5-year-old trees, (iii) patch budding on 6-month-old seedlings raised in polybags, (iv) patch budding in situ on 1-year-old shoots of adult trees, (v) air-layering, (vi) mound layering, (vii) cleft-grafting on 8- to 10-month-old seedlings raised in polybags, (viii) whip-grafting on 8- to 10-month-old seedlings raised in polybags, (ix) stone-grafting on 40- to 45-day-old seedlings and (x) stem cuttings. Air-layering was significantly superior to the other methods from March to May. Side grafting (June, July and October) and patch budding in situ (April, May and June) gave the best (and similar) results. Veneer grafting and patch budding in polybags gave poor results. In mound layering trials 64% of shoots struck roots and 72% of them established in polybags. The success in cleft grafting was high in September (58%) followed by 54% in August while the success in whip grafting was 44 and 40% in August and September, respectively. Air-layers separated from the mother tree and nursed in polybags for about 3 weeks gave 94% survival after transplanting in the field. Despite low success veneer grafts and patch budded plants in polybags gave 92 and 80% field establishment, respectively.

In 10-year trials 40-50% success was achieved by air-layering 1-year-old shoots during July to September. IBA at 500 p.p.m. improved rooting. With patch budding the highest success (71%) was recorded in July.
