Abstract
SUMMARY Transplanted crop recorded the lowest total weedpopulation and dry matter and similar to dry seeding on 0days after nursery sowing. Total weed population and drymatter was lower under early sowing on 0, 7 and 14 DANSas compared to delayed sowings. Sequential applicationof herbicides effectively controlled Echinochloa sp . and D. sanguinalis while control of Eragrostis sp. and L.chinensis was very poor. Transplanted crop recorded thehighest rice grain yield, at par with dry seeding on 0 DANSbut significantly higher than dry seeding on later dates.Three hand hoeings gave significantly higher grain yieldthan herbicides. Rice seeding directly on 0, 7 and 14 DANSproduced similar grain yield under herbicides and threehand hoeings. Further delay in seeding significantly re-duced grain yield under herbicides as compared to handhoeings. REFERENCES Behera AK and Jena SN. 1998.
