Resumo:  ABSTRACT This study aimed to evaluate the effect of chiseling and gypsum application on soil physical properties, soybean root growth and grain yield. An experiment was carried out in Londrina, Paraná state, Brazil, under a randomized complete block design, with six replications. The soil in the experimental area is classified as a dystroferric Red Latosol (Oxisol), containing 720 g kg-1 of clay. The experiment comprised four treatments: (1) continuous no-tillage (CNT) system without gypsum application, (2) CNT with gypsum application at 3.5 Mg ha-1, (3) chiseled soil without gypsum, and (4) chiseled soil with gypsum application. Regardless of gypsum application, chiseling increased water infiltration rate in soil and reduced penetration resistance. Gypsum application affected neither water infiltration nor soil penetration resistance in both no-tillage (NT) and chiseled soil systems. Moreover, gypsum application improved soybean root development at a depth range of 0.20-0.40 m in NT system. Chiseling increased root growth in the surface layer (0-0.20 m depth). Either isolated or combined, chiseling and gypsum application had no impact on soybean grain yield throughout one cropping season.
