Effect of tillage systems and weed management practices in two transplanted lowland rice crops grown in sequence
Acta Agronomica Hungarica 45 (1), 63-67
Abstract: A field experiment was conducted to study the interactive effects of tillage systems with and without summer ploughing and weed management practices on the growth and yield of two rice crops grown in sequence during the dry and wet seasons. Summer ploughing (dry season) reduced the weed problem, especially the sedges, which are difficult to control with other methods. As a result of better weed control, puddling with tractor or power tiller enhanced rice productivity by 7-8%. In both seasons, puddling with power tiller or tractor cage wheel, supplemented with either hand weeding twice or application of butachlor 1.5 kg ha-1 + hand weeding, was found to be the most economic weed management method in a transplanted lowland rice-rice sequence.
