Abstract:
The present experiment was conducted during rabi season of 2020-21 at College of Horticulture, Dr. Y.S.R Horticultural University, Venkataramannagudem, West Godavari district, Andhra Pradesh, to study the interaction effect of dates of planting and genotypes on growth and yield of potato. Eight potato genotypes (HT/14-95, HT/14-109, HT/12-834, HT/16-113, HT/12-116, HT/10-1554, HT/12-830, HT/15-240) with Kufri Surya as check were evaluated for their growth and yield performance at two planting dates i.e. 10^th November and 17^th November. Experiment was laid out in factorial RBD design replicated four times. Results revealed that plant height, plant spread, leaf area, average growth rate, number of tubers per plant, diameter of tubers, and length of tubers of potato were significantly influenced by interaction effect of planting dates and genotypes while the interaction effect was found non- significant on average tuber weight, marketable and total tuber yield per plant and marketable and total tuber yield per plot.
