Comparison of Tillage Different Method Effects on Used of Water in Agronomy of Zea Maize

According to this consideration, preparing land and seed bed preparation is the first step in planting each agricultural crop and also it has high importance. This investigation was done in a loamy soil that consist of wheat straw in one of Shoush city farms in order to surveying tillage different methods effect on agricultural and technical indices on zea maize. This experiment compared and evaluated by 3 treatment and 3replication in complete randomized block design. treatments consisted of: conventional tillage by a moldboard with 30cm +2 time longitudinal Disk +leveller (T1),one time tillage by using of compound tillage machine ( chisel pillar ) +2time longitudinal Disk (T2) and low tillage with 2 time longitudinal Disk+1time cross plough(T3).Results showed that Consumptive use in T1treatment by using 2160m3 water in irrigation period and in T2& T3 treatments42 and 19percent, respectively spend little water than T1.maize plant density in T2treatment has the most density amount,73763plant per hectare and T1&T3(1 and 13percent,respectively) had less density than T2.wheat seed yield in T3 method by 8/95 tons per hectare have the most yield amount in unit square rather than T1 and T2treatments With 8/46 and 8/15 tons per hectare. Cost of operations of land preparation T2 and T3 rather than standard method with 750000 Rial per hectare, decreased from tillage cost to 40 and 27percent, respectively.
