A master’s thesis at the College of Agriculture at the University of Basrah discussed the response to the effect of spraying with sorghum extract and spraying periods on the growth and yield of wheat and its accompanying bush The researcher's message included Khitam Mohsen Hanoun A study of two factors, the first factor included the levels of spraying with sorghum extract with Atlantis pesticide, which are (c1,c2,c3,c4,c5), which were placed in the secondary plates, while the second factor included the spraying periods during the growth stages of a wheat crop, which are (T1,T2,T3) which are placed in the main panels The results of the study showed the superiority of the C5 level in reducing the dry weight of high-leaved bushes and broad-leaved bushes, while it led to an increase in most of the growth characteristics and yield components, and gave the highest grain yield, and the T2 spraying period excelled in reducing the dry weight of thin-leaved bushes and broad-leaved bushes, and increased Most of the growth traits and achieved the highest number of spikes and the weight of 1000 grains. The thesis aims to study the effect of spraying with sorghum extract and spraying periods on the growth and yield of wheat and its accompanying bush Recommended letter By introducing the allelopathic phenomenon in an applied manner within the integrated bush management programs, due to the results it can achieve in combating the bush and increasing the yield with the least impact on the environment. Introducing the trait of allelopathic effort within the programs of breeding and improvement of crops in light of the production of varieties characterized by their high allelopathic effort in discouraging jungles. Experimenting with plant extracts other than sorghum and knowing their effect in combating wheat bushes.
