Study some performance indicators and soil physical properties for wheat Zagros variety

Abstract EN

The effect of soil moisture and tillage depth was studied on some mechanical properties for type tillage machine (moldboard plow) and soil physical characteristics on wheat Zagros variety at two soil moisture levels of 13-15%and 15-17% and three levels tillage depth of 10,12 and 14 cm.

The experiments were carried out in a factorial experiment under randomized complete block design with three replications.

The results showed that the soil moisture 13-15%is significantly better than the soil moisture 15-17% as well as tillage depth 10cm was significantly superior to the other two tillage depth 12 and 14cm in all studied conditions.

The results showed fuel consumption of 9.181 and 8.817 L.ha-1, slippage percentage of 8.360 and 7.960 %, field efficiency of 66.649 and 69.516 %, soil moisture content of 13.842 and 14.212 %, soil bulk density of 1.312and 1.263 Mg.m-3, total soil porosity of 50.490 and 52.339 % percentage of germination of 88% and 93% and production of wheat crop of 1.357 and 1.545 ton.Dounm-1 for soil moisture 13-15% and tillage depth 10 cm, respectively.
