A new variety of dwarf cashew was released by the Directorate of Cashew Research, under the Indian Council of Agricultural Research, at Puttur in Dakshina Kannada on Thursday.

Mr. Nayak said that it was evaluated for about 10 years and found unique with respect to plant height, compact spreading habit, nut size and apple colour and quality. Though the variety is not a much good yielder, it can grow well even under shade conditions. The apple colour is red, attractive and has less fibre content. The variety is pruning responsive, has long flowering duration and a variety flowers in the first year of planting. It has stem galling like coffee. It is suitable for home gardens. It best suits one who is fond of bonsai and opts for pot culture.

In the fourth year of planting, it began to yield one kg to 1.5 kg of nuts. The plant grew up to 2.5 m high and spread up to six m during the 10th year of planting, Mr. Nayak said.
