Published by Elsevier B.V. All rights reserved. (ii) In the savannah, plant rice in mid-May to Mid-June, depending on the rains. More commonly applied in rainfed and upland areas, DDSR is a crop establishment practice wherein seeds are sown directly into the soil. Direct-seeding of rice has the potential to provide several benefits to farmers and the environment over conventional practices of puddling and transplanting. CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) Ngo Duc Minh . Direct seeded rice seems more suitable in multiple cropping programme due to early maturation.

The seed requirement for DSR is also high, 8-10 kg/acre, compared to 4-5 kg/acre in transplanting. Rice in typical upland ecosystem is grown under direct seeding with minimum input (fertilizer, insecticide, fungicide, herbicide) use. Lowlands and upland areas where the only source of water for irrigation is rainfall, dry seeding of rice is practiced. By adopting the invention, cultured seeds are evenly dispersed on gelled material produced by mixing sodium alginate and agar by means of direct seeding. Growing upland rice: a production handbook – Africa Rice Center (WARDA) 5 Table 1.

Aside from helping farmers address the high labor cost in rice production, DDSR has proven to reduce water consumption as no rice seedling is being transplanted into standing water. The yields are also comparable with transplanted rice if crop is properly managed. In Bangladesh, upland aman and boro rice is more productive and it is one of the surest methods of obtaining good yield. In a field study the biological efficiency of intercropping in direct-seeded upland rice was determined at the University of Agriculture Faisalabad for two consecutive years.
