Abstract :
A laboratory study was conducted to assess the herbicidal potential of root exudates of three rice cultivars (ADT–36, BPT and IR–20) against germination and growth of common crop field weed i.e. barnyard grass (Echinochloa crus–galli L.). Various concentrations (5, 10, 15 and 20%) of root exudates were prepared from the underground part of rice cultivars from the postharvest rice fields. The studies revealed that all the three rice cultivars were exhibited significant inhibition on growth and development of weed species. Among the rice cultivars, ADT–36 exhibited the greatest inhibition on the seed germination (86%),seedling growth (83%), dry weight (81%) of barnyard cross than BPT and ADT–36. The inhibition percentage depends on extract concentration . The order of inhibition of the rice cultivars was ADT–36 > BPT > IR–20 on barnyard grass.
