Allelopathic Effects of Avena Fatua L. on Wheat Cultivars of District Kohat, KPK, Pakistan

Faiq Allaud Din, M. Adnan, Shafiq Ur Rehman

Avena. fatua L commonly called wild oat has been increasing enormously both in irrigated and rain fed regions of Pakistan and in other parts of the world as well. It is annual grassy weed and difficult to eliminate due to their seeds shattering before crop maturation. The study aims at evaluating its damages in selected wheat varieties (KT-2000 and LOCAL) that are cultivated in Kohat region of Khyber Pakhtunkhwa (KP) Pakistan. Several crops have been screened for their antibacterial activities to use them as antimicrobial agents such as Cabbage (Brassica oleracea L.) and Garlic (Allium sativum L.) Among crops wheat is an important constituent of the traditional diet all around the world so we also need to investigate the antibacterial activities of wheat. Antibacterial studies of weed induced wheat varieties were also carried out on two bacterial strains i.e. Escherichia coli and Shigella sonnei by using agar well diffusion method. Wheat seedlings treated with different concentrations of aqueous extracts of weeds (25%, 50%, 75% and 100%) was compared with control seedlings. The increasing concentrations of weeds resulted in significant decreases in the root and shoot lengths of wheat varieties along with their fresh and dry biomasses. Chlorophyll a and b, carotenoids’ content and total soluble proteins (TSP) were also negatively affected depending on weeds’ concentrations. Similarly, the medicinal potency of wheat seedlings was affected adversely specially at higher concentration of weeds’ treatments. we can conclude A. fatua adversely affected the morphological, physiological and biochemical characteristics of wheat seedlings However, on the other side, the concentration of soluble sugars was significantly and positively influenced by the application of weed extracts’ treatments, which shows accumulation of sugars in both roots and shoots of the seedlings of both wheat varieties. Soil profile of both wheat varieties was insignificantly altered as all the treatments showed no major differences as compared to control [1,2].
