Abstract

Pruning aims at producing maximum number of suitable shoots and is one of the chief factors responsible for the survival of the lac insects and the ultimate crop yield. Systematic trials on lac cultivation on ghont in Madhya Pradesh were carried out for the first time. Results indicate that pruning for Baisakhi crop (October/November to June/July) should be carried out in April of the same year to allow six months' time and for Katki crop (June/July to October/November) in May of the previous year to allow thirteen months' time for the development of maximum number of suitable shoots after pruning.
