Influence of Plant Growth Regulators on Growth, Root Tuber Yield and Quality of Orange Flesh Sweet Potato (Ipomoea batatas (L.) Lam.) Varieties

Effect of Bioregulators on Growth, Tuber Yield and Quality of Sweet Potato (Ipomoea batatas (L) Lam.) Under Hill Zone of Karnataka

“…The possible reason is due the application of GA 3 which enhances the lateral buds and vegetative growth which in turn increases the number of axillary branches per plant. These results are in line with findings of Rao et al, (2017) in sweet potato, Abbas (2011) in carrot, Mahesh and Sen (2005) in okra.…”

“…Application of GA 3 played an important role in enhancing the mean length of internode on main vine due to cell elongation and cell division. These results are in a parallel with the results of Barani et al, (2013), Rao et al, (2017), Rajak (2018) in sweet potato. Among different levels of bioregulators, GA 3 @ 200 ppm had a significant influence on vine girth.…”

“…Then the starch readily converted into sucrose and thus the amount of total sugar content increased. The results pertaining to total sugar was similar as that of Rao et al, (2017) and Rajak (2017) in sweet potato andGeetha et al, (2014) in bittergourd.…”

“…The data regarding tuber yield and quality characters as influenced by bioregulators are furnished in Rao et al, (2017) and Rajak (2017) in sweet potato and Kim et al, (2005) in Chinese yam.…”
