“…There was also a discrepancy between the weed dry matter growing in control treatments, which indicates that the crop species significantly impact the growth of the bush growing with it and ranged according to its severity. The wheat tolerance against weeds has also been confirmed by [23,24] when mentioned that the wheat crop is considered one of the successful crops that have a high tolerance to weed comparative and then maintain high yields in the presence of weeds.…”

Total releasing phenolic compounds and allelopathic potential of the three sunflower genotypes Helianthus annuus L. residues were evaluated under open field conditions on weed flora associated with the proposed crops; wheat, broad bean and flax which are cultivated usually after the sunflower crop as successive crops. After getting seed from the sunflower crop. After getting seeds, sunflower plant parts were chopped and incorporated with field soil using a rotavator. Regarding the phenolics, total phenolic compounds released from sunflower residues were increased in-field soil and reached the highest concentration in the fourth week after mixing with soil. Significant suppression of weed flora was observed when the weed density and weed dry matter were reduced. Sakha sunflower genotype had the most effect, while Ishaqi genotype had the least amount of phenolic compounds. The residue of the Sakha genotype effectively suppressed over 80% of targeted weeds. The results indicate that the allelopathic potential of sunflower residues can cause suppression of weed flora which can be useful as an attractive alternative natural way to reduce synthetic herbicides as sustainable weed management.

“…A weed-killer or herbicidal compound is a substance used to kill plants, particularly weeds or other undesirable species ( Almarie, 2022 ). The n-hexane, methanol, and water extracts of root and shoot at 5, 10, and 15% (w/v) of the plant exerted noticeable herbicidal action on Phalaris minor Retz.…”

“… Weed Density (plant m 2 ) Weed flora was calculated before the end of the season using a woody frame 1m 2 dimension dropped in each plot [5].  Dry Weight of the Weeds (gm m2): The weed plants were cut near the level of the soil surface at an area of 1 m2 from each experimental unit and dried in an electric oven at a temperature of 70 °C for two days, and then measuring their dry weight [4,5].  branch per plant: estimated by calculating the total branches from Ten plants randomly selected from the middle of the row and then divided by 10.…”

“…It is one of the profitable crops, especially in lands where traditional crops do not exist, as well as in new cultivation areas [2]. The most important problem facing the cultivation of sesame that makes the farmers refrain from growing this crop is its weak competition with weeds, especially in its early stages of growth, which causes significant losses in yield and oil [3,4]. Determining the appropriate time for weed control is one of the agricultural management basics, which leads to reduced effort and time and leads to an increase in the quantity and quality of the final yield, in addition to trying to minimize the use of herbicides, which have begun to raise concerns about their negative impact to humans and the environment.…”

To determine the Critical Period for Weed Competition in Sesame crop and predict the total yield losses by weed competition, a field experiment was conducted during season 2023 using three sesame varieties which were Wadaa, Rafidain, and Had by making the field free of weeds by hand for periods of 1, 2, 3, 4, 5 weeks beginning from crop emergence. Then, allowed weeds to grow after these periods until the end of the growing season. Results of the study determined this period by making the field free of weeds for three weeks after emergence depending on acceptable yield losses of 10-12% in comparison to the yield of sesame plants served by weedy-free free throughout the growing season. Sesame yield Losses resulting from weed competition all over the growing season ranged from 66.42 to 95.95% for the three cultivated varieties. Accordingly, this study recommends that weed control must continue from cultivation until three weeks after emergence and not delay it for this period by using mechanical control methods or by using specialist herbicides, which are still effective against weeds until this period to avoid unacceptable loss of the economic yield.
