Abstract

The aim of this study was to assess the decomposition rate of crambe straw under different soil management practices based on no-tillage system. The experiment was carried out at the experimental area of the Agronomic Institute of Paraná - IAPAR, regional center of Santa Tereza do Oeste, Paraná, Brazil. Treatments consisted of four soil management practices: Traditional No-tillage System - TNTS – Chisel Plowing Tillage System - CPTS – No-tillage System with Application of Gypsum - NTSG - and Quality No-tillage System - QNTS. The treatments were distributed in randomized order in parts subdivided on time with fifteen macro-plots of 20 m x 25 m. The assessments took place on 0 (zero), 7, 15, 30, 60, 90, and 120 days after crambe crop harvest. Decomposition was determined quantitatively through the analysis of the decomposition rate of crop residues using litter bags. Average loss of crambe phytomass was significantly different (p>0.05), mainly for CPTS and NTSG, around 0. 63% day-1 and 0. 71% day-1, respectively. The longest half-life period (66 days) was observed on QNTS with bristle oat and white lupin consortium, and the shortest half-life period (45 days) was observed on CPTS.

Key words: Crambe abyssinica, litter bags, half-life period.
