Abstract:

Allelopathic potential of wheat straw aqueous extract was tested for germination and growth response of Convolvulus arvensis and Dactyloctenium aegyptium and cotton (Gossypium hirsutum L.) with different extract concentrations i. e. 0%, (control), 25% v/v, 50% v/v, 75% v/v and 100% v/v. Wheat straw aqueous extract showed some inhibitory effect on the germination of cotton, however shoot and root development was stimulated with moderately diluted extract in both lab. and pot experiments. Germination and growth of C. arvensis was significantly inhibited with all extract concentrations. Wheat straw aqueous extract reduced the germination of D. aegyptium, whereas its growth remained unaffected.
