AbstractA field experiment is carried out in one of the rice fields in Al-Shatra district during the summer season 2013-2014 to study the effect of response of varieties of rice (Oryza sativa) (parents 1 , pond , jasmine 4, research , Firat and ward 33) to five levels of mixed organic and chemical fertilizers.
Results of the study show that the six cultivars differed significantly among the qualities studied. The superiority of class parents in the average number of days from planting to 50% flowering (115.26 day) and an area of flag leaf (39.30 cm2) and the length of Dahlia (30.24 cm) and the number of grains Baldalia (149.30 pill) while outweigh class Ward 33 in the average number of days from 50% flowering until physiological maturity (33.50 day) and plant height (116.60 cm) and weight of thousand grain (21.73 g) and holds the grain (4.04 mecagerm.h -1) and Winning bio (9.26 mecagerm.h -1) and harvest index (43.58%).
The results show that the mixing 3 mecagerm.D-1 of the organic fertilizer with 33% of the chemical fertilizer F4 and mixing of mecagerm.D-1 of the organic fertilizer (F5) and the level gives the highest rate in holds grains (3.92 mecagerm.h -1) and Bioloyical yeild (9.14 mecagerm.h -1) and harvest index (42.92 %) as compared with the other level of the treatment.
The results show that treatment of (ward 33) with F5, F4 treatment gave the highest quotient of grain and winning biological and harvest index and the number of grains in the Dahlia and plant height.
Tnteration of spannt gives F5& F4 treatments the highest rate and the superiority of moral character in the number of days from planting to 50% flowering, as well as the length of Dahlia and space science paper.
