Crambe grain yield affected by compaction degrees of an Oxisol
Marins, Araceli Ciotti de; Reichert , José Miguel; Secco, Deonir; Bassegio, Doglas; Nava , Daniela TrentinCrambe is a new crop that produces oil used for biodiesel production. Soil compaction in a no-tillage (NT) system is one of the main challenges for sustainable grain production in soil clay. The objective of this study was to evaluate the effect of compaction degree on crambe grain yield over two years. The levels of artificial compaction were generated using a roller compactor (0, 1, 3, and 5 passes) under a N...
Mathematical modeling of soil and water losses in Oxisol under management systems
Chang, Pablo; Secco, Deonir; Marins, Araceli Ciotti de; Rizzi , Rogério Luis; Tokura, Luciene KazueThe objective of this work was to mathematically model the losses of water and soil in a Oxisol with different management systems, through the physical attributes of soil and vegetation cover. The experimental area was located in the municipality of Santa Tereza do Oeste – PR, in a soybean field. The treatments consisted of three management systems: traditional no-tillage system, plastered no-tillage system, no...
Soil physical properties and maize grain yield after cover Crops
Castro, Mayra Beatriz Semiano; Secco, Deonir; Marins, Araceli Ciotti de; Bassegio, Doglas; Souza, Samuel Nelson Melegari de; Zanão Junior , Luiz AntonioStudies involving cover crops in areas managed under no-tillage system are of great scientific relevance to seek the sustainability of agricultural crops. This study aimed to evaluate the impact of the use of cover crops on the structure of a clayey Oxisol under no-tillage system and its effect on corn yield. The treatments consisted of the use of six cover species: millet (Pennisetum glaucum), dwarf pigeon pea...
Impact of land cover, slope and precipitation on soil water infiltration
Vidaletti, Vitória Fenilli; Marins, Araceli Ciotti de; Secco, Deonir; Rizzi, Rogério Luís; Chang, PabloThe knowledge of the rate of water infiltration in the soil is of fundamental importance for the proper use and management of the soil, in addition to helping in the planning of irrigation and drainage techniques. Mathematical modeling is indicated as a tool capable of anticipating events and pointing out alternatives that lead to the productive maintenance of the environment, and given the difficulty of obtain...
Rendimento de grãos e de óleo do crambe em um latossolo: análise espacial e mod...
Marins, Araceli Ciotti deThe growing environmental awareness regarding production and use of renewable fuels has led many of countries to create policies to benefit producers of renewable fuels. Thus, the search for raw materials for production of biofuels, which do not conflict with the global food production and exhibit similar performance to fossil fuels, has generated interest towards crambe, a crop of high oil content, inappropria...
