Abstract
Studies to find out most effective method of vegetative propagation of cashew were in progress since 1952 in Kerala.
In the early trials, budding, side grafting and propagation by cuttings did not succeed.
Air-layering and inarch grafting were highly successful and among these two methods, the former was simpler and cheaper.
Eventhough 80–100 per cent success was obtained during November – April, the post separation mortality of layers was very high.
Application of IAA – 250 ppm improved root growth in layers.
The non-flowered shoots gave higher percentage of rooted layers than the flowered shoots.
There was no difference in the four rooting media tried.
In three year old plants, the layers showed better root system than the seedlings.
Rooting of air-layers was correlated with shoot growth cycles and the establishment was better when the layers were planted in polythene bags, with made up soil supplied with Hewitt’s nutrient solution.
