The traditional management applied by the Native Community of Chambira (NCCh) is based on agroforestry plots with diverse species and areas with rotation of legumes, cassava and maize. The objective was to evaluate behaviour of the physicochemical indicators of soil quality with traditional crop management in the NCCh. A completely randomised design was applied, where the treatments were traditional mixed fruit management (MF), crop rotation (CR) and native forest (NF) as reference. Physical indicators of the surface layer did not show differences, the apparent density (AD) and the resistance to penetrability (RP) increased with depth; chemical indicators...

Composition and degradation of anthocyanins in blue and purple grain wheat during bread production were investigated using the HPLC-MS/MS method. The most abundant anthocyanins were delphinidin-3-rutinoside (blue grain wheat), cyanidin-3-glucoside and peonidin-3-glucoside (purple grain wheat). Peonidin-3-glucoside was also the most stable during grain treatment while delphinidin-3-glucoside had the greatest loss. Both blue and purple grain anthocyanins decreased significantly during bread production to 41.81% and 70.10% after baking, respectively, and to 24.21% and 60.00% after short-term storage, respectively. The blue grain wheat anthocyanins were...

Genetically modified (GM) crops have brought huge economic benefits to mankind, however, at the same time, their safety issues are drawing growing attention. This investigation was conducted to assess whether the long-term cultivation of GM glyphosate resistant maize CC-2 effects bacterial communities in the rhizosphere soil. A 2-year follow-up trial was conducted, and soils were sampled at various plant developmental stages. The bacterial community structure of the rhizosphere soil was analysed by the high-throughput sequencing and compared with the near-isogenic non-GM maize Zheng 58

Current ecological trends for production of forage for livestock indicate a need for small usage of fertilisers while increasing productivity. The study aimed to assess yield and interactions of selected Lolium and Festulolium species grown in mixtures with Trifolium repens and fertilised with NS, regarding mutual interactions based on available indicators. A two-year field study (2016-2017) was carried out in southern Poland and the research objects were designed on degraded chernozems. The highest yield was observed for mixtures: L. multiflorum + T. repens and L. × boucheanum + T. repens sown...

Replacing Bordeaux broth and synthetic fungicides by less invasive approaches of fungal disease control remains a challenge for both conventional and organic viticulture. Silicon (Si) application has been proposed as a viable alternative for the control of pathogens and other stresses in agriculture. In a three-year field trial, we tested the effect of foliar and soil application of colloidal silicon on its availability in vineyard soil and pants, the performance and quality of yield, and finally, the control of powdery mildew for grapevine cv. Grüner Veltliner. Soil application of colloidal silicon increased plant-available Si, but only foliar application...

Quality and productivity of hybrid wheat depending on the tillage practicesOriginal Paper

The aim of this study was to assess the impact of soil tillage systems on technological characteristics, mineral composition and grain yield of selected hybrid wheat cultivars grown in variable climatic conditions. The following factors were studied: tillage systems, namely conventional (CT), reduced (RT) and no tillage (NT) and hybrid cultivars of winter wheat (Hyfi, Hybiza and Hystar). Cvs. Hyfi and Hybiza were characterised by good technological parameters and protein quality, and additionally by a higher Fe and Zn content and a higher grain yield than cv. Hystar. Meteorological
