Crop succession and rotation with surface liming on nematode management and soybean yield

Abstract - The objective of this work was to evaluate the effects crop production systems under no-tillage and with surface liming, after 10 11 years, on nematode populations soybean (Glycine max) grain yield. Twelve treatments were established in a randomized complete block design, four replicates. plots consisted three (monoculture, followed by fallow off-season; succession, millet rotation, rattlebox, Urochloa ruziziensis, corn, each one an off-season), subplots, rates dolomitic limestone (0.0, 2.0, 4.0, 8.0 Mg ha-1). Crop rotation sucession favors higher yield, reducing population Heterodera glycines soil roots increasing Helicotylenchus spp. increment reduces increase H. decrease Pratylenchus brachyurus
