Author(s): Satya Prakash Singh, Santosh Kumar Singh, Bansi Lal and Shailesh Kumar Singh
Abstract: Field experiments were conducted at main experiment station Department of vegetable science, Narendra Dev University of Agriculture and Technology Kumarganj, Faizabad (UP) during 2011-12 and 2012-13. To study five planting dates 17 October, 27 October, 7 November, 17 November and 27 November with four potato cultivars Kufri Ashoka, Kufri Pushkar, Kufri Bahar and Kufri Arun on incidence of early blight (Alternaria Solanai) during crop season. The minimum incidence of early blight was recorded (24.05% and 22.34% ) on 17 November and the maximum incidence of early blight recorded (38.84% and 37.26%) when crop was planted on 17 October during 2011-12 and 2012-13, respectively however, the variety Kufri Ashoka more susceptible with early blight in respect of Kufri Bahar, Kufri Pushkar, and Kufri Arun. The production of potato tubers was obtained i.e. 471.48q. And 487.48q/ha was significantly highest with 17 November planting of variety Kufri Arun during 2011-12 and 2012-13, respectively. Thus, the results revealed that the best time for planting of potato in eastern Uttar Pradesh on 17th November which shifted from 7th November of planting due to climate change.
