Assessment of Tillage Different Method Effects on Used of Fuel in Cultural of Zea Maize

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 zeamaize. This experiment compared and evaluated by 3treatmentsand 3replication in complete randomized block design. treatments consisted of: conventional tillage by a moldboard with 30cm +2 time longitudinal Disk +leveler(T1),one time tillage byusing 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 lots of consumed fuel amount in T1 treatment with 63/5liter per hectare and T2&T3treatments, 48 and 36percent respectively spend little fuel rather than T1.maize plant density in T2 treatment 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.
