Abstract: An experiment was conducted at Department of Agricultural Meteorology, CCS HAU, Hisar (Lat.: 290 10’ N, Log.: 75036’ E & 215.2 m above msl.), Haryana, India during the rabi season in the year 2013-14 & 2014-15. Experiment was laid out with four growing environments (D1-last week of Oct., D2-second week of Nov., D3-last week of Nov., and D4- second week of Dec.) along with four irrigation levels applied at different phenophases (I1-CRI, I2- CRI and heading, I3- CRI+ jointing and milking, I4- CRI+ jointing +anthesis and dough stage) Strip plot design was adopted with four replications. The main aim of this study was to compute the correlation and regression results. Both maximum and minimum temperature at vegetative stage was positively correlated with yield and yield attributes in both the years. Minimum temperature at vegetative stage also had positive correlation except the parameters like length of spike, number of grains, seed yield and harvest index in 2013-‘14 year. Both maximum and minimum temperature that prevailed during reproductive stage was negatively correlated in both the years. RH (m) and RH (e) at vegetative stage had negative but positively correlated at reproductive stage in both the years. Wind speed and rainfall negatively correlated at vegetative and reproductive stages in both the years. Dry matter production was directly and linearly related with IPAR. The slope value of the regression line showed that D1 was highly efficient in utilizing PAR for dry matter production. The irrigation treatment I3 was more efficient in utilizing PAR as compared to other irrigation treatments in 2013-14 & 2014-15. The accumulated heat unit was found to have direct liner relationship with dry matter production.
