Dormancy breaking and effects on tuber yield of potato subjected to various chemicals and growth regulators under greenhouse conditions

Abstract

This study was conducted to check the effect of various chemicals and growth regulators was checked on dormancy breaking of potato tubers, and also to check the subsequent effects on tuber yield under greenhouse conditions. The chemicals were tested on three potato cultivars having different dormancy release characters. Among the chemicals the tubers treated with rindite exhibited the highest sprouting ratio in all the cultivars. Cultivar Diamont took the least period of time for 50% of tubers to sprout followed by cultivar Atlantic. Highest decay ratio of tubers was observed for cultivar Atlantic and Diamont treated with thio-urea. The tubers treated with thio-urea induced the highest number of sprouts as compare to all other treatments. Significant differences were observed among the treatments and cultivars for various yield characters
