Conservation agriculture practices in a peanut cropping system: Effects on pod yield and soil penetration resistance

ABSTRACT Conservation agriculture principles applied to peanut can reduce soil erosion and production costs when cultivated in rotation with sugarcane. Still, the problem compaction is leading cause of skepticism about efficacy this practice. This research aimed study effect three management strategies compared conventional for cv. IAC-OL3, sugarcane using MEIOSI (method intercropping occurring simultaneously) system agronomic practices additional analysis on changes physics properties. The trial was conducted 2019-2020 Planalto municipality (São Paulo, Brazil) under a green-harvested field, randomized complete block experimental design. consisted four treatments (conventional tillage, minimum tillage chisel, strip-tillage, no-tillage) five replications. Although no differences were verified bulk density porosity among treatments, highest values penetration resistance observed no-tillage treatment all evaluations (before planting, at beginning flowering, before after harvesting) comparison tillage. difference diminished from planting end cycle. Furthermore, low disturbance maximum covering straw significantly increased available water capacity reduced incidence severity groundnut ringspot virus (GRSV) plants. Consequently, both minimum-tillage have pod yield average by 695 991 kg ha -1 more than strip-tillage respectively, without terms quality losses.
