Effect of Sowing Depth , Varity and Harvesting Date On Quality Of Wheat Grain Under Condition of Sulaimaniyah Province

Abstract

ABSTRACT This experiment was conducted in experiments Field Crops Section of the Directorate of Agricultural Research field in Bakra Joe / Sulaymaniyah during the growing season (2014-2015), was carried out the experiment in accordance with the panels dissident system factorial in split system in R.CBD design With three replicates, the study included three depths for agriculture are (4 , 6.8) cm, varieties of wheat used are: (Arras, parents of 95, the parents of 99, Adana, Frame), was harvesting three different dates, have been studying the quality characteristics of the varieties of wheat examined and there were no significant differences in the character of protein appears under the influence the study factors and their interaction may outweigh the harvest time the first high grain ratio reached (12.493%) and the superiority of class parents 95 date of the first harvest when the depth of the seed 8 cm in the recipe wet kidneys while significant differences did not appear under the influence of the three factors and their interaction in the recipe Dry kidneys and also excelled treatment of class fathers 99 and depth of sowing 8 cm for the time of the third harvest in the percentage of ash reaching (2.036), and excelled treatment of class Frame and depth of the seed (6 cm) on the date the third harvest in total carbohydrate content in terms of (76.703).
