Title

Effect of Puddling, Water and Weed Management Practices on Weed Dynamics and Yield of Transplanted Rice (Oryza sativa L.)

D. Subramanyam; C. Raghava Reddy; D. Srinivasulu Reddy Indian Journal of Weed Science 2006

Other claims from this paper (6)

Intervention effect Intensive puddling with continuous submergence reduced weed density and dry weight.
Intervention effect Intensive puddling with continuous submergence raised grain yield 40%.
Intervention effect Oxadiargyl plus hand weeding produced the lowest weed density and dry weight and higher control efficiency and yield.
Intervention effect Oxadiargyl plus hand weeding raised yield 39.5% over unweeded control.
Intervention effect Cinmethylin was the least effective weed control.
Recommendation The authors recommended combined intensive puddling, continuous submergence, oxadiargyl and hand weeding.
