- Guidelines for dry seeded aman rice (DSR) in Bangladesh(IRRI, 2014) Gathala, M.K.; Sudhir-Yadav; Mazid, M.A.; Humphreys, E.; Ahmed, S.; Krupnik, T.J.; Rashid, M.H.; Chauhan, B.S.; Kumar, V.; Russell, T.; Saleque, M.A.; Kamboj, B.R.; Jat, M.L.; Malik, R.; Tiwari, T.P.; Mondal, M.; Rahmand, M.; Saha, A.; Hossain, K.; Saiful Islam; Mcdonald, A.Dry seeded rice (DSR) is becoming an attractive option for farmers as it has a much lower labor requirement than manually transplanted rice. Labor for transplanting rice has become scarce and costly because laborers are shifting from agriculture to industry, public works and services, and migrating abroad. DSR can be readily adopted by small farmers as well as large farmers, provided that the required machinery is locally available (e.g., through custom hire from agricultural service providers). Best practice involves using a 2- or 4-wheel tractor-drawn drill to seed in rows into nontilled or dry tilled soil, as for wheat. Because the soil is not puddled, DSR also has a lower water requirement for crop establishment, and may require less frequent irrigation than puddled transplanted rice grown with alternate wetting and drying water management during dry spells. Where arsenic contaminated groundwater is used, less irrigation means less arsenic brought to the soil surface. Furthermore, accumulation of arsenic in the grain and straw is much less if the soil is allowed to dry between irrigations to let air (oxygen) into the soil (“aerobic” conditions) than in continuously flooded rice.
Publication - Guidelines for Dry Seeded Rice (DSR): in the Cauvery Delta Zone, Tamil Nadu, India / Sudhir Yadav and others(CSISA, 2014) Sudhir-Yadav; Ganeshamoorthy, R.; Humphreys, E.; Rajendran, R.; Ravi, V.; Mussgnug, F.; Kumar, V.; Chauhan, B.S.; Ramesh, T.; Kamboj, B.R.; Gathala, M.K.; Malik, R.; Jat, M.L.; Mcdonald, A.Dry seeded rice (DSR) is becoming an attractive option for farmers in the Cauvery Delta Zone (CDZ) due to the elimination of the labor requirement for nursery preparation and maintenance, pulling out and transport of seedlings, and transplanting. Because the soil is not puddled, DSR also has a lower water requirement for crop establishment. Furthermore, the total crop cycle is shorter by 10−15 days because of the absence of transplanting shock. These features of DSR are of major importance for the Cauvery Delta (see below) because of the increasing scarcity of water for irrigation in the area. DSR can be readily adopted by small farmers as well as large farmers, provided that the required machinery is locally available (e.g., through custom hire). Best practice involves using a 2- or 4-wheel tractordrawn drill to seed in rows in dry or slightly moist soil.
Publication - Guidelines for Dry Seeded Rice (DSR): in the Terai and Mid Hills of Nepal(CSISA, 1999) Krishna Prasad Devkota; Sudhir-Yadav; Ranjit, J.D; Sherchan, D.P.; Regmi, A.P.; Akhtar, T.; Humphreys, E.; Chauhan, B.S.Dry seeded rice (DSR) is becoming an attractive option for farmers as it has a much lower labor requirement and establishment cost than manually transplanted rice. Labor for transplanting rice has become scarce and costly because laborers are shifting from agriculture to industry, public works, and overseas employment. DSR can be readily adopted by small farmers as well as large farmers, provided that the required machinery is locally available (e.g., through custom hire). Best practice involves using a 2- or 4-wheel tractor-drawn drill to seed in rows in nontilled or dry tilled soil, as for wheat.
