introduction main part of energy consumption in agricultural mechanization is tillage operations therefore optimization of energy consumption in tillage operation is very important. a management method for system to optimize in agriculture is simple additive weighting (saw) methodology that this method can operate according to criteria of the systems. this method states that, which system has b...

in the first experiment, the chemical composition, apparent metabolizable energy (ame), ame corrected for nitrogen (amen), true metabolizable energy (tme), tme corrected for nitrogen (tmen) values of the sweet almond meal were determined in adult leghorn cockerels. the second experiment was performed to evaluate the effects of different levels of sweet almond meal at 0, 100, 200 and 300 g/kg on...

a one-way moldboard plow turns over soil in only one direction. problems created by this type of tillage in iran include compaction of boundary regions, decreased efficiency of irrigation and disruption of bed leveling, requiring the use of bed-leveling equipment every few years. to overcome these problems, the use of a two-way plow with two harrows which turns over the soil to both the left an...

Soil amendments (e.g., compost) require uniform incorporation in the soil profile to benefit plants. However, machines may not mix them uniformly throughout upper layer commonly explored by plant roots. The study focuses on using image texture analysis determine level of mixing uniformity following passage two kinds harrows. A 12.3-megapixel DX-format digital camera acquired images soil/expande...

Tillage is one of the most important practices affecting soil physical and hydraulic properties. Its effects may vary intensely according to tillage method. This study aims evaluate different methods (moldboard plow+disk harrow, moldboard plow+rotary tiller chisel harrow) drainage (subsurface non-drainage) on properties in a clay loam soil. The experiment was conducted split-plot time statistic...
