Abstract:
A field experiment was conducted on apical cuttings in potato to standardize the node number of apical cuttings of different potato varieties for better rooting and survival percentage at Horticultural Research Station, Dr. Y. S. R. Horticultural University, Chintapalli, Andhra Pradesh, India during Rabi 2022. Observations were recorded for five randomly selected plants from each treatment combination for growth variables viz., including the survival percentage of cuttings, relative height of plantlets (cm), average growth rate (%), the number of roots per cutting and the length of the longest root (cm). Kufri Lima exhibited the highest survival percentage of cuttings, relative height of cuttings, number of roots per cutting, and length of the longest root. Additionally, two-node cuttings were found to have a significant effect on the number of roots per cutting and the length of the longest root. The interaction between varieties and node numbers also yielded a significant effect on the number of roots per cutting. Therefore, for improved growth in apical cuttings, the use of two-node cuttings in Kufri Lima is recommended.
