COMPARISON OF TOW EARTH SURFACE MACHINE ON SOIL COMPACTION, WATER CONSUMPTION AND WHEAT YIELD IN SHOUSHTER REGION

Evaluating of laser leveling system effect on physical and mechanical characters of dust, the examination done with using of 2 attendance of laser leveling (exact ) and common leveling system in agriculture farm of Azad university in shoushter unit during farming year of 2011-2012 and 2012-2013. For comparing average performance and performance's parts and also penetrable balance used from chance blocks in 5 repeats. For average comparison which is related to dust outwards weight and dust difficulty used of T test with 10 repeat. Water consumption and usage utility of water measured during 2 years. The result of variance analysis show that levering effect on performance, seed weight, virgin length and herbal height are meaningful in around of 1% in statically level and using of laser method cause increase of 6% in compare with common method. Also the results are shown that laser leveling system haven't effect on outward weight of dust and dust jam in around of 0- 15 cm and also on penetrating dust. Water consumption utility leveling method is shown 3% higher in compare with common leveling method. For successful plant, providing seed situation has vital importance. In result, suitable situation for seed cause good relation of seed with dust. Also in next stages, done growing root and herbal pitch suitably. In harvesting stage maybe encounter with spraying product if surfacing not be suitable. Nevertheless final aim is same distribution of water in farm with considering suitable slope, texture, and dust formation. With considering economical and technical limitations which there is in improving impacted irrigation, common method of irrigation in Iran is superficial. Irrigation output in superficial method has dependence to factors such as same slope, earth dimension, and texture and dust formation. It's maybe, farming slope be common (3 - 6) but often it isn't same and so cause un same distribution of water on plants and their roots system and so cause heterogeneous growing in area. Also increase using of water and so irrigation output and water consumption utility, decrease. With considering drought problems and resource limitations, suitable management in optimum using in seed situation and in herb situation is necessary and important. Exact surfacing as a universal solution can solve many disadvantages and problems which there are in surficial system. In exact leveling method, uses laser technology of sender and receiver. In this method like as engineering method uses each topography method and providing topography plan which may be done with using of topography equipment and or laser equipment. Also after recognizing natural slope, this slope or needing slope can define for sender system. The receiver which installed on box receives dates from sender system and with sundering message to electrical system cause the blade become seesaw and also cause devastate of dust. This system can install on cylinders, scrappers and other road systems such as Grinder. Because laser leveling systems come to country in late years and some internal factors produced of them, doing some studies about their usage effect in farms on water consumption utility and also physical and mechanical characters of dust are necessary. The studies which do Young and colleagues (2001) in china showed that usage output of water increase by exact surfacing method. Bahri and Khatib (2001) evaluated the effect of 2 slopes in around of 0.3% and 0.5% and the length of 3 dimensions in around of 50, 100, 150m on wheat performance. Highest wheat performance was related to earth surface with very exact method by 0.5% slope and 150m length and lesser performance was about UN surface earth. Bari and colleagues (2002) studied short term effects of surface functions on physical and biological characters of dust. The result of this examination which done in silly - Lummi dust showed that surfacing functions hasn't effect on physical characters of dust and it's more effect is on biological characters. Abdolsattar and Khan (2002) evaluated exact surfacing effect on cotton performance. Their results showed that water consumption amount in common surface method is 37% more than exact surface method by laser. The results also showed that the vast changes of
