CARVALHO, Laércio Alves de et al. Productivity and economic feasibility of sugar cane in different systems of tillage in west-central Brazil. Rev. de Ciências Agrárias [online]. 2011, vol.34, n.1, pp.199-211. ISSN 0871-018X.

We studied the effect of different tillage systems where soil analyzed the economic feasibility of manufacturing and technological attributes of sugar cane cultivated in an area formely with soybean in Rio Brilhante-MS, Brazil, considering the physical attributes of an Acrustox. The tillage systems were: conventional tillage (CTI, CTII and CTIII), subsoiling (S) and no-tillage (NT), forming a randomized complete block design, with five replicates, which were analyzed by F test (p < 0.05), followed by Tukey test (p < 0.05). Significant differences were found between treatments for variable bulk density and total porosity in layers 0.21 to 0.40 m depth. The yield and tiller number showed no significant differences, but looking at the implementation cost of each treatment, there was greater economic viability in the no-tillage (NT).

Palavras-chave : Bulk density; no-tillage.
