Effect of Weather Variables on Wheat Yield by Different Stages of Wheat through Box Plot Design

Abstract

Present study examines the effect of climatic factor e.g. Temperature (Maximum and Minimum), Relative humidity (Morning and Evening), Evaporation and Rainfall variation on the yield of different stages of wheat in Samastipur district of Bihar by using Box plot method. The data of wheat yield of 29 Years (1984-2013) was taken from Department of Agricultural Economics, RAU, Pusa and Weather Variables (1984-2013) was taken from Agro-metrology Unit, RAU, Pusa. Box plot will used to estimate the effect of climate variables on the stages of wheat yield. At tillering, dough and maturity stages, morning relative humidity was identified as the most important variable in explaining the yield variability.
