Abstract

Some winter crops sown in no-tillage system can represent an important alternative to nutrient cycling. The objective of this work was to evaluate the production of dry matter (DM) and accumulation of nutrients for winter cultivation in the West of Paraná. The experimental design was a randomized block, with four treatments and six replications. The treatments were represented by four different winter crops (oat IPR 126, crambe FMS Brilhante, radish common cultivar and wheat BRS Taruma), and the DM, the contents of C, N, P, K, Ca, Mg and C/N ratio in DM and nutrients accumulation were determied The dry matter production was higher for radish with 4.929,14 kg ha-1. The different winter crops used influenced the contents of C, N and C/N ratio. The other studied characteristics were not influenced. Among the four winter cultivation the radish presented larger production of dry matter. The chemical composition was influenced by the cultivations, the contents of C, N and C/N ratio, consequently in the contribution differentiated in the area. The winter cultivation in the studied conditions influences the accumulation of magnesium.

Key words: Nutrient cycling, decomposition, mineralization.
