Abstract

This research was conducted to introduce a conservation tillage method suitable for dry seeded rice in Golestan province in the form of a completely randomized block design. The treatments of experiment were no-tillage with a direct seeding machine, minimum tillage with a combination tillage machine at a depth of 15 cm + leveler + planting rice seeds with a seed drill, minimum tillage with a chisel packer at a depth of 15 cm + leveler + planting rice seeds with seed drill, minimum tillage with disc at a depth of 10 cm + leveler + planting rice seeds with seed drill and conventional tillage at a depth of 25 cm + transplanting (control). The studied parameters were the time required for tillage and planting operations, the field capacity of tillage and planting machines, the number of established plants, yield and yield components. The results showed that the minimum time required for tillage and planting operations is 1.4 h/ha and the highest field capacity belongs to no-tillage treatment with 3.7 hectares per hour. The maximum time required for tillage and planting operations in the conventional treatment is 456.7 hours. In among of conservation tillage methods, apart from no-tillage, due to the non-significance results of the yield components, the yield also was not significant and its values were lower than the grain yield in the conventional treatment. Therefore, among the treatments, the highest average grain yield and harvest index were obtained in the conventional treatment, equal to 5238 kg/ha and 51.4%, respectively.
