Abstract

WHEAT is one of the most important food crops in Iran and making efforts for yield increasing is very essential .Since TILLAGE methods have major effects on agricultural productivity thus in this study, effect of different TILLAGE methods on WHEAT yield were evaluated in silt clay loam (Typic Calcixeroll) during 3 successive years begun in 2000. A Randomized Complete Block Design with six TILLAGE methods were used to evaluate WHEAT yield in irrigated and non-irrigated practices.Treatments were included T1) subsoiling + moldboard plowing + disking T2) subsoiling + disking T3) moldboard plowing + disking T4) chisel plowing + disking T5) disking T6) no TILLAGE. Results showed that TILLAGE methods had no significant difference in increasing or decreasing bulk density during plant growth stages and %21 soil moisture content has been caused to pulverize almost %60 soil clods with less than 25 mm diameter .Median weighted diameters of the clods (MWD) for T1, T2, T3, T4, T5 were obtained 29, 34, 31, 34, 28 mm respectively. TILLAGE methods had significant difference on the WHEAT yield and average of WHEAT yield for treatments T1 until T6 were 3041, 2581, 2750, 2123, 1940, 1745 kg/ha in irrigated and 2238, 2234, 2258, 2338, 2547, 1509 kg/ha in non-irrigated practices respectively. Also results indicated that deep TILLAGE with subsoiling before plowing (T1) and irrigation during plant growth stages increased WHEAT yield about 300 kg/ha rather than conventional methods (T3) and minimum TILLAGE with disking (T5) had the highest yield in non-irrigated WHEAT condition.
