Physical Attributes of an Irrigated Oxisol after Brassicas Crops under No-Tillage System
نویسندگان
چکیده
In no-tillage areas, cover crops are a continuous supply of organic matter and other positive improvements to the soil’s structural quality. We evaluated soil physical attributes in area cultivated with brassica on residues under no-tillage. Six coverages [1-Brachiaria (B), 2-Sunn hemp (S), 3-Pearl millet (M), 4-S + B; 5-B M; 6-S M] native (Cerrado biome), were for resistance penetration (RP), density (SD), macroporosity, microporosity, volumetric moisture (VM), weighted mean diameter, geometric aggregate stability index. RP VM differed among treatments; no compacted layer was observed at up 0.4 m depth; Low SD Brachiaria Pearl (Poaceae) compared Sunn (Fabaceae) deeper layers; The principal components cluster analysis indicated B M as most promising coverage deep structuring. quality indicators showed that isolated cultivation or intercropped another culture presented best results characteristics. indices aggregation where species Poaceae Family being isolation each other.

Cover crops and herbicide timing management on soybean yield under no‐tillage system
The objective of this work was to evaluate the effect of cover crops and timing of pre-emergence herbicide applications on soybean yield under no-tillage system. The experiment consisted of four cover crops (Panicum maximum, Urochloa ruziziensis, U. brizantha, and pearl millet) and fallow, in addition to four herbicide timings (30, 20, 10, and 0 days before soybean sowing), under no-tillage sys...
متن کاملBacterial Diversity Under Different Tillage and Crop Rotation Systems in an Oxisol of Southern Brazil
Microbial diversity can be used to assess the impact of agricultural practices on the long-term sustainability of cropping systems. The aim of this study was to investigate changes in soil bacterial diversity as a result of the impact of different soil tillage and crop rotation systems in an oxisol of southern Brazil. Bacterial diversity was examined in the 010 cm layer in two field experiments...
متن کاملWeed Control Using Conventional Tillage, Reduced Tillage, No-Tillage, and Cover Crops in Organic Soybean
Soybean field experiments were performed to investigate the weed-suppressing effects of different tillage systems and cover crop mulches at two locations in southwest Germany during 2014 and 2015. The influence of three different tillage systems on weed control efficacy, soybean plant density, and crop yield was determined. In the no-till system (NT), two different cover crops, (rye and barley)...
متن کاملReduced Tillage in an Irrigated Potato Rotation
Soil erosion continues to be a threat to agricultural productivity worldwide, with soil losses in the United States exceeding 3 billion tons annually. Wind and water erosion have caused dramatic declines in soil productivity. Erosion protection and associated conservation of nutrients, organic matter, soil water holding capacity and biota are significant concerns. Pimentel et al. (1995) estimat...
