AbstractA field experiment was conducted in experimental field of Department Of Field Crops- Agriculture College/ University Of Anbar (Abu-Ghariab) during spring and autumn season of 2016 to study the effect of three maize cultivars (Massara, Sarah, and Maha) and four levels from bread yeast extract (Saccharomyces Cervisiae L.) 0, 10, 20, and 30 g L-1 were sprayed on the foliar. The two factors of the study were organized as split plot within RCBD with three replications. However, cultivars occupied the main plots while the yeast levels were put in the sub plots. The results of the study showed the following: In spring season, the level 30 g L-1 was significantly in plant height, number of ears, plant dry matter weight, weight of 500 grain, and the level 20 g L-1 gave significant differences in leaf area. While level 10 g L-1 showed a significant difference in grain in number a row total and grain yield of. In autumn season, 30 g L-1 level recorded significant in number of ears, leaf area and plant dry matter weight. While the level of 20 g L-1 was superior in plant height, number of rows and total yield grain. However, the level of 10 g L-1 was prominent in 500 grain weight and number of rows.
In the spring season, Maha cultivar was significantly superior in the plant height, plant dry matter weight, and number of grains in row. While Sarah cultivar was significantly superior in leaf area, number ears in plant, and number of rows in ear, weight of 500 grains, total yield grain. As for autumn season, Massara cultivar was significantly superior in leaf area number of ear, and plant dry matter weight. While Sarah cultivar was significantly prominent in number of rows in ear). While Maha cultivar was significantly superior in plant height, weight of 500 grains and total yield.
As for the interaction between the study two factors, it significantly affected in most studied traits, however Sarah cultivar plants that treated with 30 g L-1 gave the highest values of most traits means and for the two seasons of the study.
