摘要

A field experiment was conducted during 2003 to 2006 to study different machinery for the establishment of rice (Oryga satva L.) and the effect on subsequent crop growth, productivity and energy. The study was made for direct seeding (dry bed), drum seeding (wet bed), mechanical transplanting (puddled and unpuddled) and manual transplanting (puddled) in subsequent crops of wheat. The mean yield of hybrid rice was higher (8.52 t/ha) with drum seeding (wet bed) that was at par with direct seeding (dry bed) and mechanical transplanting (puddled) as compared to manual transplanting (puddled) and mechanical transplanting (unpuddled). Direct seeding (dry bed) adopted in previous rice crops gave higher mean yield of wheat (5.70 t/ha) followed by drum seeding (wet bed), mechanical transplanting (unpuddled), manual transplanting (puddled) and mechanical transplanting (puddled). The net return energy of the system was high in drum seeded (170,926 MJ/ha) followed by direct seeded (169,070 MJ/ha) and lowest of 150,542 MJ/ha in manually transplanted (puddled).rnThe drum seeded rice required 3.6 % less input energy and gave 8.9 % higher output energy, whereas, direct seeded required 2.6 % less input and gave 8.2 % higher output energy as compared to manually transplanted (puddled). The direct seeded (dry bed) and drum-seeding (wet bed- unpuddled) saved irrigation water by 13 to 19 % when compared to manual transplanting (puddled).
