Abstract
Different techniques of vegetative propagation in cashew were tried with varied degrees of success at C.P.C.R.I., Regional Station, Vittal during 1977-78. The techniques tried were: (i) Veneer grafting on six month old seedlings raised in polybags, (ii) Side grafting on 3-5 year old cashew trees, (iii) Patch building on six month old seedlings raised in polybags, (iv) Patch budding in situ on one year old shoots in adult trees, (v) Air-layering, (vi) Mound layering, (vii) Cleft-grating on 8-10 month old seedlings raised in polybags, (viii) Whip-grafting on 8-10 month old seedlings raised in polybags, (ixj Stone-grafting on 40-45 days old seedlings and (x) Stem cuttings. The technique of air-layering was significantly superior over other techniques during the period of March to May. The techniques, side grafting (June, July and October) and patch budding in situ (April, May and June) were at par. Veneer grafting and patch budding tried on six month old seedlings raised in polybags did not give encouraging results. In mound layering trials 64 per cent of shoots struck roots and 72 per cent of them had established in polybags. The percentage take in cleft grafting was high in September (58%) followed by 54 per cent in August while the success in whip grafting being 44 and 40 per cent in August and September months respectively. Air layers on separation from the mother tree and nursed in polybags for about three weeks when transplanted in the mainfield established upto 94 per cent. Similarly veneer grafts and budded plants gave 92 and 80 per cent establishment in the field.
