| Summary: | Grain yield and its components of twenty genotypes of bread wheat evaluated and compared under rainfed and two Supplemental Irrigations at Gorgan agricultural research station in 2006-2007. a field experiment was conducted at two separate design , in a randomized complete block design (RCBD) with three replications.Different morphological traits including: No-grain per spike, spike per meter square , spikelets/spike, 1000 kernel weight , kernel yield were evaluate after implementation of supplemental irrigation and non irrigation in two different experiments on twenty genotypes of bread wheat. Results of simple variance analysis showed that there was a significant different between genotypes at 1 level under supplemental irrigation and non irrigation. Results of complex variance analysis showed that there was a significant difference between some traits at 1 level. Meteorology citation shows that it rains about 350 mm from November 2006 to June 2007 and rainfed environment obtained adequate water and its kernel yield reached to high possible level. The supplemental irrigation environment derived water from two sources. In this respect in soil of experiment formed deep crusting and thus damaged roots, washed mineral materials and restricted kernel yield. At supplemental irrigation and rainfed, there was a positive correlation between kernel yield with ear/m2 and thousands kernel weight. |
