Abstract
Conservation tillage has been proposed as a promising strategy to improve soil and water conservation in dryland areas. A 2-year experiment was conducted to determine the influence of crop residue remained on soil surface in conservation and conventional tillage systems on soil surface temperature, canopy temperature [using Infrared thermal imaging on a clay loam soil (Vertic Calcixerepts)] and wheat grain yield in the northwest region of Iran. Tillage treatments were conventional tillage (MD: mouldboard plough + disk harrow), reduced tillage (CD: chisel plough + disk harrow), minimum till (MT: Stubble cultivator), and no-till (NT1 and NT2: with standing stubble and total residue, respectively). Rresidues in NT1 and NT2 lowered the averaged canopy temperature by 3.70 °C over the other treatments (MD and CD) and there was a positive and significant correlation between soil surface temperature and wheat canopy temperature. Results indicated that for a dryland vetch (Vicia panonica)- winter wheat cropping system, NT2 had higher grain yield than that obtained with MD system probably owning to greater rain fall efficiency and lower canopy temperature.
