Resumo
The objective of this work was to evaluate the phytomass production,
accumulation and nutrient release and soybean yield in production systems with
cover crops in succession to soybean cultivation in dystrophic Oxysol in
Rondonópolis - MT. The experiment was conducted during the 2016/17 and
2017/18 harvests at the UFMT, Campus of Rondonópolis, in a randomized
complete block design with nine cover cropping systems with four replications.
The evaluations were performed immediately before desiccation of
management in October of 2016 and 2017, and repeated at 15, 30, 60, 90 and
120 days after desiccation. Crotalaria spectabilis and Urochloa ruziziensis were
prominent in the phytomass accumulation. C. spectabilis and U. ruziziensis
were prominent in the accumulation of nutrients, with the exception of K, Mg
and Cu, in which the sunflower + U. ruziziensis system was highlighted for the
first two and maize + C. spectabilis for Cu, in the 2016/17 season. U. ruziziensis
was highlighted in the accumulation of macronutrients in the 2017/18 crop. The
off season production systems composed of C. spectabilis, maize + C.
spectabilis, sunflower + U. ruziziensis, P. glaucum and U. ruziziensis were
efficient to increase soybean yield in succession to cover crops in southern of
Mato Grosso.
