چکیده مقاله:
Soil compaction is a main factor that reduces the cane yield in sugarcane fields, in Southwest of Iran, especially in ratoon cropping system. Therefore, sub-soiling practices could alleviate adverse effects of compaction and increased yield. In according to this aim, a study was to evaluate the effect of ratooning practice systems consisting of control (no subsoiler), two and four shanks subsoiler in two soil moisture conditions, before and after irrigation. Soil bulk density was measured in two depths of 0-20 cm and 20-40 cm, as an indicator of soil compaction. The results showed that sub-soiling with two and four shanks significantly reduced soil bulk density (p<0.01). In both depths compaction was not affected after irrigation treatment. The effect of sub-soiling was not significant for cane height, sheath moisture, leaf nitrogen content purity and refined sugar. Reduction of soil compaction significantly increased stalk weight, yield and sugar yield (p<0.05). Sub-soiling and irrigation treatments had significant (p<0.01) effect on reduction of fuel consumption.
