Conservation and conventional tillage (Challenges and Solutions)

One of the Problems in decrease agricultural production in arid and semi arid areas, low being soil organic matter.The lack of management in the use of machinery, plant residue burning, intense rainfall, lack of proper crop rotation, use of excessive fertilizers and other factors led to soils this region exposed to water and wind erosion and every year a large volume of soil due to heavy rainfall land excessive irrigation out-of-field. In this regard, six-year (2006-2012) field experiment was conducted in farm of Moghan. After the wheat harvest was done on residue. According to the conventional corn rotation in region 704 Varieties for the second crop (corn silage) were planted. The results showed that whit residue management treatments are statistically significant and lowest yield was 36.21 ton ha-1 related to no-tillage treatment. Also, lowest percent of dry matter with 8.15 ton ha-1 was related to no tillage treatment. Therefore No- tillage treatments with regard to significant yield reduction in current conditions would not recommended.
