Conservation agriculture using crop rotations and residue management is increasingly accepted in conventional agricultural systems. However, the effects on crop productivity and soil properties of different rotations, levels of use, and residue management have yet to be fully understood. Our study considered the effect of three previous crops (bread wheat, durum wheat, and corn) and four levels of residue incorporation (0%, 50%, 100%, and 200%) in a split plot design with four replicates on canola production parameters and soil chemical properties at the end of this crop. Production parameters and soil chemical properties were mostly affected by the previous crop and less by the residue incorporation rates under the conditions of this experiment; however, neither of these factors affected grain yield (ranging from 4.0 to 4.8 Mg ha⁻¹). Canola residue production was higher (9.7%) after the corn crop, regardless of the residue incorporation rate, but the harvest index was lower after this crop. Most of the soil chemical properties were also affected, revealing increased organic matter and exchangeable K when the previous crop was corn and decreased concentrations of the cations with basic reaction when the previous crop was durum wheat.

使用农作物轮作和残留管理的保护性农业在常规农业系统中越来越被接受。然而，不同轮作，使用水平和残留管理对作物生产力和土壤特性的影响尚待充分了解。我们的研究考虑了以前的三种作物（面包小麦，硬质小麦和玉米）的影响，以及在四块重复种植的菜地设计中对残渣掺入的四个水平（0％，50％，100％和200％）对油菜产量的影响。作物末期的参数和土壤化学特性。在该试验条件下，生产参数和土壤化学性质主要受前茬作物的影响，而较少受残渣掺入率的影响；但是，这两个因素均未影响谷物产量（范围为4.0至4.8 Mg ha^-1）。玉米种植后，无论残茬掺入率如何，芥花油的残渣产量均较高（9.7％），但此作物收获后的收获指数较低。大多数土壤化学性质也受到影响，当前茬是玉米时，显示出有机质增加和可交换的钾，而当前茬是硬粒小麦时，由于碱性反应，阳离子的浓度降低。
