Present investigation was conducted at Dr. YS Parmar University of Horticulture and Forestry, Nauni (HP) to study the effect of changing climatic conditions on seed yield of onion (Allium cepa L.) in mid hills of Himachal Pradesh. The meteorological data (30 years) and onion seed yield data (26 years) were collected; correlation and regression analysis between various weather parameters (temperature, rainfall and relative humidity) and onion seed productivity was done for productivity trend analysis. Weather based crop yield forecast model equation was developed and crop yield was predicted with maximum accuracy of 69 per cent. | Impact of climate variability on seed yield of onion in mid hills of Himachal Pradesh, India
