Other claims from this paper (7)

Observation Five weed species predominated in the rice experiment.
Intervention effect Puddled transplanting reduced weed dry matter accumulation relative to other planting methods.
Intervention effect Puddled transplanting produced the highest mean rice grain yield, 3.89 t/ha, among planting methods.
Intervention effect Puddled transplanting produced the highest yield contributing parameters among planting methods.
Intervention effect Direct drum seeding under puddled conditions yielded 2.82 t/ha more than direct dry seeding.
Intervention effect Sequential pretilachlor and cyhalofop-butyl was effective against mixed weed flora.
Intervention effect Pretilachlor plus mechanical weeding increased grain yield as effectively as sequential herbicides.
