Wheat (Triticumaestivum L.) is a significant food grain crop since it is a staple food. It is the primary source of proteins and calories for both animals and humans among cereal crops. Herbicides have an effect on the environment, the land, people, and animals.Allelopathy is an environmentally beneficial weed-control technique. Avena sativa L., Brassica napus L., Chenopodium album L., and Lactuca sativa L. seed germination was decreased by Meliaazedarach L. fruit extract. The major objectives of this study were to investigate how tree aqueous extract affected wheat seed germination and seedling growth through its allelopathic effects.The current study was carried out in the allelopathy Laboratory, of the Botany Department, Hazara University Mansehra, KhyberPakhtunkhwa Pakistan. The test was carried out using three varying concentrations of water extract, appropriately 5%, 10%, and 15%, using completely randomized designs. Radical and plumule lengths were determined after viewing the germination of wheat for seven days.The outcomes showed that a higher concentration of an allelopathic tree water extract boosted wheat germination. Wheat's radical and plumule lengths were dramatically lengthened at higher dosages of water extract (10% and 15%). The results of the present study are in benefit of the use of allelopathic tree extracts to control weeds in the wild and improve agricultural output.
