Wheat (Triticum spp.) is a cereal grain that originated in the Near East’s Levant region but is now grown all over the world. It belongs to the Plantae kingdom and the Poaceae family. Ethiopia is one of Africa’s biggest food aid recipients. Due to many production constraints, such as weed infestation, achieving the desired wheat production is difficult. One of the main biotic constraints in wheat development is weed infestation. Wheat is infested with a variety of weed flora, both grassy and broadleaf, due to the fact that it is cultivated under a variety of agroclimatic conditions, cropping sequences, tillage, and irrigation regimes.Weedrelated yield losses differ depending on the weed type, density, and environmental factors. Weed management practises such as cultural, mechanical, biological, and chemical weed control methods can help minimise yield loss due to weed infestation. This seminar paper’s aim is to review recent research findings on wheat weed management practises. To feed an increasing population, wheat production must increase without relying heavily on chemicals such as fertilisers and herbicides, which have unpredictable negative effects on the environment and human health. For better crop yield, weed control techniques must be improved.In the agricultural sector, improved herbicide formulations with low to no toxicity except for the target weeds seem to be in high demand in the near future.

The effect of inoculating wheat cultivar Adana 99 with Mycorrhizae and spraying nano seaweed extract and nano specific fertiliser on growth and yield was studied in a field experiment at the Extension farm in Province 41 of Husseiniya, Babylon Governorate. There were eight different therapies in the experiment. In a simple oneway experience using RCBD style, Inoculation of Mycorrhizae Glomus mosseae (GM), spray of Nano seaweeds extract (NSWE), Nano specific fertiliser (NSF), di (GM+NSWE), (GM+NSF), (NSWE+NSF), tri (GM+ NSWE+NSF), tri (GM+ NSWE+NSF), tri (GM+ NSWE+NSF), tri (GM+ NSWE+NSF),A number of plant growth criteria were reported, as well as yield (quality and quantity) parameters.In all growth and yield parameters of wheat, LSD0.05 was Inoculation of Mycorrhizae Glomus mosseae (GM), spraying of (NSWE) and (NSF), followed by the spraying combine dofdi (GM+NSWE), (GM+NSF), (NSWE+NSF), and tri (GM+ NSWE+NSF), treatment srespectively with an increment of the tri combination (GM+ NSWE+NSF) of 89.92c treatment under supervision. The same treatment had substantially higher grain and protein yields of 6.684 Mg ha-1 and 970.32 kg ha-1, respectively, than the control, which had yields of 4.019 Mg ha-1 and 404.72 kg h1.Harvest index was in the range of 35.3 to 45.6 percent for the control and tri combination, with substantial superiority for the tri, bilateral combinations, and mono treatments.When the tri combination of (GM+ NSWE+NSF) was compared to other treatments, the highest efficiency of fertilisation for output was achieved at 66.3 percent.

Nanotechnology is a multidisciplinary methodology that encompasses agriculture, medicine, materials, electronics, and food packaging due to multiple engineering methodologies, but it also requires extensive study due to controversial safety and toxicity concerns. The aim of this research was to see how chemically engineered ZnO nanoparticles (NPs) affected wheat cultivars Misr1 (tolerant) and Gimmeza11’s salinity stress tolerance in two seasons from 2018 to 2020. (sensitive). The data revealed an improvement in some biochemical parameters such as photosynthetic pigments, reduced glutathione, and the strength of some native PAGE bands of superoxide dismutase, all of which may be related to the increased intensity of some native PAGE bands of superoxide dismutase. related to salt tolerance and malondialdehyde reduction Due to the application of ZnO NPs, some changes in protein biosynthesis of wheat leaves were observed between the presence (1) and absence (0) of some bands, which could be linked to the antagonistic effect between metals, especially Zn. For the majority of the parameters studied, the most effective concentration was 1.0ppm. ZnO NPs were assessed at the molecular DNA level of wheat plants using the Inverse sequence- tagged repeat (ISTR) assay against five primers, with the highest polymorphic bands (86.6 percent polymorphism) at F9, B3 primer and 20 unique bands with primer F4, B7, The highest polymorphic bands treated with ZnO NPs as compared to the control indicate the degree of DNA alterations, but the function of DNA repair system enzymes cannot be overlooked. On two wheat cultivars, the biological analysis revealed the effectiveness of ZnO NPs as a foliar spray (Misr 1 and Gimmeza11). To determine their protection, we used Wistar Albino rats and repeated doses for 28 days to determine the median lethal dose (LD50). ZnO NPs had no impact on the levels of liver and kidney functions, as well as histopathological events, which all stayed within normalised values, allowing the controversy about the use of ZnO NPs in a wide range of fields to be turned around switch it off .

The article presents data on the shift in the accumulation amount of the total of chlorophyll a+b, flavonoids and the nitrogen status of plants with different doses of organic, organomineral and mineral fertiliser in a five-field grain-coupled crop rotation. The revealed patterns of changes in plant nitrogen nutrition levels allow us to conclude that only soft winter wheat and maize in the Belgorod region have a positive impact on the after-effects of organic fertilisers. Only in the case of wheat is the difference between the doses of the mineral and organic fertilisers important. Increased mineral fertiliser doses contribute to accumulated soil nitrogen accumulation and as a consequence, to a decrease in plant nitrogen status.
