Effect of variety, type of cutting and IBA concentration on rooting of croton (Codiaeum variegatum) cuttings

The present experiment was conducted to find out the interaction effect of variety, type of cutting and IBA concentration on rooting in cuttings of croton. Overall performance of hard wood cutting of broad leaf variety treated with 400ppm IBA was found significantly superior in inducing the highest rooting percentage (82.34%), took lesser time for sprouting (10 days), survival percentage (80.04%) and sprouting percentage (88.66) than other treatments. The hot and humid condition were conducive for growing semi-hard wood and hard wood cuttings of broad leaf as well as narrow leaf variety of croton which were able to show good performance. Out of three type of cuttings, semi-hard wood cuttings and 200ppm IBA was found better in comparison to 400ppm IBA with broad leaf for rooting and establishment. Therefore, it is concluded that croton can be multiplied by cuttings under green house condition with IBA treatments.
