Resumo
The challenge is to increase agricultural production while
avoiding the opening of new areas. An alternative is to increase productivity
through research and development of new technologies. The spatial
arrangement of plants promoted by sowing crossed of soybeans may
contribute to this increase. Given the above, we sought to evaluate the
performance of soybean sown of crossed shape in tillage systems. The
experimental design was a split plot, with the corresponding portions of the
systems of tillage and subplots to sowing soybeans types. Each treatment
had six replicates. The tillage systems were: conventional tillage, reduced
tillage and no-tillage. The soybean sowing was carried out in a conventional
manner, with parallel lines, and so crossed, where the sower went twice in
the same area in perpendicular directions. The cultivar TMG 123 RR.
Evaluations consisted in checking the severity of the rust, agronomic
characteristics and operational performance of machines . The lower severity
of rust was observed in the no-tillage and conventional tillage with
conventional sowing. The sowing crossed of soybeans had higher plant
height at flowering, maturation and first pod, grain yield in no-tillage system
and demanded higher fuel consumption and energy demand.
