Production Technology for Direct Seeded Rice. New Delhi, India: Rice- Wheat Consortium for the Indo-Gangetic Plains.pp16. ISSN: 0972-2084 Continued puddling over decades has led to deterioration in soil physical properties through structural breakdown of soil aggregates and capillary pores, and clay dispersion. Puddling forms a compacted layer (plough pan) that restricts the percolation of water, causing temporary waterlogging, and restricted root penetration and growth for succeeding crops after rice. Transplanting operations are usually performed by migratory labor,which has an element of seasonality and thus increasingly becomes a serious concern for the timely transplanting of rice and maintaining a plant population sufficient to achieve high rice productivity. It is therefore important that alternative methods that are more water-efficient and less labor-intensive be developed to enable farmers to produce more at less cost. One way to reduce water demand is to grow direct dry-seeded rice (DSR) instead of the conventional puddled transplanted rice.........................
