Two filed experiments were carried out in a sandy soil private farm located in Qassasin Ash Sharq, El Husseiniya, Fakous District, Sharqia Governorate, Egypt, during the winter seasons of 2019/2020 and 2020/2021, to study the effect of spraying four plant leaf extracts in addition to spraying with distelled water (Moringa oleifera L., Chinopodium album L., Lantana camara L. and a mixture of the previous three extracts) at three  concentrations (50, 75 and 100%) in three different times (40, 80 and 120 days after sowing) on wheat yield and its attributes as well as both grains crude protein and carbohydrates content  of wheat cultivar Misr 1, also the influence of the past treatments on both weeds number and dry weight/m² were investigated, Split-split plot design in three replicates was used. Results indicated that spraying wheat plants with 75% concentration of Chinopodium album leaves extract during early growth stage (tillering) recorded an increment valued as much as 18% in grain yield and a 33% as well as 21% decreasing in weeds number and dry weight/m².
