Abstract

A laboratory experiment was conducted in one of the laboratories of Silo General Company for Grain Trading the variety Eba 99 during the 2019 season in order to study the response of the seeds to treatments of Moisture and heat. -7, 20 and 32), and the second factor was three Moisture treatments (10%, 14% and 16%), temp 32 was significantly superior, were highest value of germin perc. and reached 94.33 %, while temp. 7 was lowest value and reached 89%.Moisture level treatment exceeded 14% and washighest germin perc., which reached 92%, and 16% gave the lowest percentage of germ. that reached 90%.The interaction between temperature and Moisture levels showed significant superiority, and the interaction treatment 10x32 gave the highest value of 97%., The treatment of the heat level 32 was significantly superior to the rest of the treatments and gave the highest value of specific weight 77.03 kg while the treatment of the heat level - 7 gave 75.47 kg with an insignificant difference from the heat level 20, which amounted to 75.20 kg, The treatment of the level of moisture in the specific weight was significantly superior, and the treatment of 16% gave the highest value, and it reached 75,9 kg, the treatment of heat 32 was superior to the speed of germin. and gave the lowest value of 3.44 days, while treatment 37 gave the highest value of 4.22 days The humidity level of 10% gave the lowest number of days for germin., while the level of ride of 16% gave the highest value of the number of days to reach germin. 4.22days, that temperature degree treatment of 32 °C gave the highest in weight of 1000 grains 35.50 g.
