Impact of Direct Seeded Rice (DSR) For Resource Conservation
Puddling doesn’t have much influence on rice yields. Many changes and innovations have contributed to the expanding use of resource conserving technologies in the country. One of the most important has been the development, testing and marketing of a low cost seed-cum-fertilizer drill which can establish crops with a minimum of soil disturbance, can take best advantage of residual soil moisture...
متن کاملTraits and QTLs for development of dry direct-seeded rainfed rice varieties
The development of rice varieties for dry direct-seeded conditions can be accelerated by selecting suitable traits. In the present investigation, traits hypothesized to be important for direct-seeded conditions in rainfed systems, including seedling emergence, early vegetative vigour, nutrient uptake, nodal root number, and root hair length and density, were characterized to study the genetic c...
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 کاملSelf-propelled Leidenfrost droplets.
We report that liquids perform self-propelled motion when they are placed in contact with hot surfaces with asymmetric (ratchetlike) topology. The pumping effect is observed when the liquid is in the Leidenfrost regime (the film-boiling regime), for many liquids and over a wide temperature range. We propose that liquid motion is driven by a viscous force exerted by vapor flow between the solid ...
متن کاملMolecular Mapping of QTLs Associated with Lodging Resistance in Dry Direct-Seeded Rice (Oryza sativa L.)
Dry direct-seeded rice (DSR) is an alternative crop establishment method with less water and labor requirement through mechanization. It provides better opportunities for a second crop during the cropping season and therefore, a feasible alternative system to transplanted lowland rice. However, lodging is one of the major constraints in attaining high yield in DSR. Identification of QTLs for lo...
