Abstract:
In comparison of winter cereals radiation use efficiency in nitrogen fertilizer availability, a factorial experiment in randomized complete block design was conducted during the years 2013/2014 /2015 in Gonbad Kavous region, Iran. Winter cereals were evaluated at zero and optimum nitrogen rates. Results showed LAI varied from 6.08 in triticale to 3.28 in hull less barley in first year while for second year maximum and minimum LAI were obtained in triticale (4.51) and oat (3.38) respectively. In both years, the most accumulation total dry matter was related to triticale. The maximum and minimum K were calculated for bread wheat (0.86) and triticale (0.67) and varied from 0.86 in two rowed barley to 0.56 in hull less barley in first and second years. RUE varied from 2.02 gr Mj?1 in durum to 2.78 gr Mj?1 in triticale and from hull less barley (3.44) to six rowed barley (2.80).
