Evaluation of Tillage Methods and Deep Plowing

B. J. Phipps, A. S. Phillips and B. J. Tanner


 
ABSTRACT

No-till, reduced tillage and conventional tillage were evaluated. Stands were more difficult to establish on the no-till and the reduced till was intermediate to the other two methods. Stand reduction due to Fusarium was greatest in the reduced till plots. Deep plowing was shown to be of benefit. The conventional tillage tended to yield less than the other cultural methods, however it was easier to establish a stand. In 2000 the reduced till plots were damaged more than the other treatments, especially the conventional tilled treatment. The stands were reduced due to fusarium wilt. The data does not suggest any tillage system to be clearly superior except deep tillage. Water stress is reduced by deep tillage. The largest advantage of no-till is the savings in equipment costs. The results show that the deep tillage loosens the soil for more than one year. The conventional tillage produced short fibers. Deep plowing increased the fiber length.
