Weather forecast models of potato yield using principal componant analysis for Sultanpur district of Eastern Uttar Pradesh, India

The present investigation entitled “Forecast Models of Potato Yield Using Principal Component Analysis for Sultanpur District of Eastern Uttar Pradesh.” Time series data on yield of potato and weekly data from 40th SMW of the previous year to 6th SMW of the following year on five weather variables viz., Minimum Temperature, Maximum Temperature, Relative humidity 08.30hrs, Relative humidity 17.30hrs, and Wind-Velocity covering the period from 1990-91 to 2011-12 have been utilized for development of preharvest forecast model. Statistical methodologies using multiple regression, principal component analysis for developing pre-harvest forecast model have been described.
