Protection of the soil against wind and water erosion is inevitable. Conservation tillage is defined as any tillage and seeding system that maintains a minimum of 30 percent surface residue cover on the soil surface after planting to reduce soil erosion by water or wind. In addition to economic benefits of the conservation tillage systems, increase in soil organic matter and fertility, and moisture conservation can be mentioned. The disadvantages of this system are related to the cost of tillage equipment, fighting weeds and emerging plants from the seeds of the previous crop. Recently, no-tillage has been introduced as a conservation tillage system in central Iran with mixed results. The main problem reported with no-till in the soils with low structural stability is poor crop establishment in high residue condition. Strip tillage is an alternate way to improve crop establishment in such conditions. In the strip tillage system, a narrow width of soil where the seeds are planted is shallowly tilled while the residues between the crop rows are left undisturbed. The main objective of the research was to design, develop and evaluate combined strip tillage implements that make a loosened soil layer with a width and depth of 150 and 100 mm, respectively, in one pass. The strip tillage implement was consisted of four units: (a) a row cleaner, (b) two side-cutting disks, (c) a strip tillage tool and (d) a roll packer. Four types of strip tillage implement based on the geometrical shape of its strip tillage tool were developed. These implements were strip tillage implement with: (i) rigid shank equipped with triangular share, (ii) bi-level rigid shank equipped with triangular share, (iii) double bent-blade subsurface tillage tool and (iv) two rippled disks. In this study, the effect of these strip tillage implements working in three residue levels (no residue, standing residue and high residue conditions) and at two water contents (0.7 and 0.9 plastic limit) on row cleaning performance, soil strength, cross sectional area of the disturbed soil, clod mean weight diameter (MWD), percentage of seed emergence, plant establishment and dry matter accumulation in plants were studied. The experiment was conducted in a clay loam soil at the Isfahan University Technology Research Farm. Strip tillage machine with bi-level rigid shank equipped with triangular share has the lowest soil strength and the smallest clod mean weight diameter (MWD) and created the most appropriate tilled strip shape. The benefit of strip tillage machine with bi-level rigid shank equipped with triangular share was that it does not need to use side cutting disks for limiting the width of disturbed soil and so the number of units used in this type of strip tillage machine was lower. There was no significant difference in percentage of emergence and plant establishment among the three levels of residue and indicates that strip tillage implements worked well in all residue conditions. The results showed that, in addition to having benefit of conservation tillage, the stripe tillage system can have acceptable plant establishment in arid and semi-arid areas of central Iran . The advantages of the strip tillage machine with bi-level rigid shank equipped with triangular share can be recommended as a conservation tillage system for these areas.
