ABSTRACT
The field experiment was conducted at Department of Agricultural Meteorology, CCS Haryana Agricultural University, Hisar (Lat.: 290 10’ N, Log.: 75036’ E & 215.2 m above msl), Haryana, India during the rabi season of 2013-14, 2014-15 and 2015-16, respectively. 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, irrigation applied at different phenophases (I1-CRI, I2- CRI and heading, I3- CRI+ jointing and milking, I4- CRI+ jointing +anthesis and dough stage). The design was strip plot with four replications. The main objective of work was to effect in growing environment and irrigation scheduling on phenology. The intercepted PAR calculated for wheat crop. Phenophases of wheat crop from CRI to physiological maturity (PM) having less difference in all growing years. The results revealed that the intercepted PAR (IPAR) differed due to variation in dates of sowing. IPAR values increased linearly from CRI to dough stage (DS). Higher values of IPAR was obtained in D4I4, D4I1 and D3I1 where as lower IPAR values in D1I2, D1I4 and D1I4 treatments during the year 2013-14, 2014-15 and 2015-16, respectively to the other treatments. Dry matter production was found to be closely related to the amount of IPAR under different growing environment at Hisar conditions.
Key words:Growing environments, irrigation levels, wheat phenophases, intercepted PAR
