CLIMATE CHANGE AND POTATO PRODUCTION IN INDIA

摘要

India produces about 24 million tonnes of potato from 1.32 million hectares under the crop. The Northern plains contribute about 84percent of the total produce. The bulk of the produce comes from states of Uttar Pradesh (UP), West Bengal (WB), Bihar and Punjab contributing 40, 32, 6 and 6percent, respectively. The area, total production and mean tuber yield at the national level increased during the period 1980 to 2007 by 92, 200 and 55 percent respectively. The heat sensitive potato crop is mostly confined to Indo-Gangetic plains under irrigated conditions due to climatic constraints. Small scattered areas as rainfed crop are grown in hills during summers and in kharif season in plateau region, whereas winter season crop in the plateau region is irrigated.
