Sustainable Weed Management for Unpuddled Transplanted Rice
Submit Manuscript | http://medcraveonline.com non-rice crops in a rotation such as wheat. Therefore, puddling for rice transplanting should be avoided as it has adverse effects on the succeeding upland crops. Unpuddled transplanting is an alternative method for rice establishment which can be adopted to overcome these problems and also to reduce cost of rice production. For this system, the lan...
متن کاملResponse of Rice Genotypes to Weed Competition in Dry Direct-Seeded Rice in India
The differential weed-competitive abilities of eight rice genotypes and the traits that may confer such attributes were investigated under partial weedy and weed-free conditions in naturally occurring weed flora in dry direct-seeded rice during the rainy seasons of 2011 and 2012 at Ludhiana, Punjab, India. The results showed genotypic differences in competitiveness against weeds. In weed-free p...
متن کاملIntegration of Agronomic Practices with Herbicides for Sustainable Weed Management in Aerobic Rice
Till now, herbicide seems to be a cost effective tool from an agronomic view point to control weeds. But long term efficacy and sustainability issues are the driving forces behind the reconsideration of herbicide dependent weed management strategy in rice. This demands reappearance of physical and cultural management options combined with judicious herbicide application in a more comprehensive ...
متن کاملEffects of Seeding Time and Weed Control Methods in Direct Seeded Rice (oryza Sativa L.)
Field experiments were conducted during the 2 year period from 2008 and 2009 to determine the effects of three seeding dates and seven weed control methods in DSR. The results suggested that seeding in the first week of July reduced weed density and biomass, increased kernel weight, leaf area index, and kernel yield compared to seeding rice in the first week of July. Amongst weed control method...
متن کاملEffect of Weed Management and Seed Rate on Crop Growth under Direct Dry Seeded Rice Systems in Bangladesh
Weeds are a major constraint to the success of dry-seeded rice (DSR). The main means of managing these in a DSR system is through chemical weed control using herbicides. However, the use of herbicides alone may not be sustainable in the long term. Approaches that aim for high crop competitiveness therefore need to be exploited. One such approach is the use of high rice seeding rates. Experiment...
