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). |
