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...
Change in injection angle as alternative for diesel engine fueled with biodiese...
Paiva, Paulo Henrique; Gurgacz, Flavio; Gralick, Jonas; Bassegio, Doglas; Souza, Samuel Nelson Melegari de; Secco, DeonirBiodiesel properties have a significant impact on engine performance. The disadvantages of biodiesel include poor atomization. To overcome this problem, engine parameters such as the injection angle can be changed. The objective of this study was to evaluate the effect of changes in the injection angle of an injector pump on the performance of a diesel engine fueled with various biodiesel blends. The experiment...
Maize and sorghum root growth and yield when intercropped with forage grasses
Sarto, Marcos Vinicius Mansano; Borges, Wander Luis Barbosa; Bassegio, Doglas; Rice, Charles; Rosolem, Ciro Antonio [UNESP]Made available in DSpace on 2022-05-01T10:19:02Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01; Integrated crop–livestock systems that intercrop forage crops with grain crops are effective for increasing forage production and improving nutrient cycling and soil health. However, the potential for root competition when maize (Zea mays L.) and sorghum [Sorghum bicolor (L.) Moench] are intercropped wi...
Deep Soil Water Content and Forage Production in a Tropical Agroforestry System
Sarto, Marcos Vinicius Mansano; Borges, Wander Luis Barbosa; Bassegio, Doglas; Nunes, Márcio Renato; Rice, Charles W.; Rosolem, Ciro Antonio [UNESP]Made available in DSpace on 2022-05-01T15:46:11Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-03-01; Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); Agroforestry systems integrating tree and forage growth are important for maintaining soil health but may change the soil’s physical-hydric properties. Our goal was to inv...
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...
Soil microbial community, enzyme activity, C and N stocks and soil aggregation ...
Sarto, Marcos V. M.; Borges, Wander L. B.; Bassegio, Doglas; Pires, Carlos A. B.; Rice, Charles W.; Rosolem, Ciro A. [UNESP]Made available in DSpace on 2020-12-12T01:33:13Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-01-01; The impact of agricultural land-use on soil microbial community composition and enzyme activity has not been extensively investigated in Ultisols. We investigated soil health parameters by analyzing phospholipid fatty acids (PLFAs), extracellular enzyme activity, C and N stocks, and soil structure. Four...
Effects of calcium and magnesium silicate on the absorption of silicon and nutr...
Sarto, Marcos Vinicius Mansano; Lana, Maria do Carmo; Rampim, Leandro; Rosset, Jean Sérgio; Sarto, Jaqueline Rocha Wobeto; Bassegio, DoglasWheat is a plant that accumulates silicon (Si). The application of silicon to the soil may influence the absorption of nutrients by the plant and, therefore, its nutritional balance. In this study, we aimed to evaluate the effects of calcium and magnesium silicate (CaSiO3/MgSiO3) on the ability of wheat (Triticum aestivum L.) to utilize silicon and absorb nutrients from soils collected in the state of Paraná, B...
Guar root and shoot growth as affected by soil compaction

Cover crops and straw management on yield components of crambe
Bassegio, Doglas; Santos, Reginaldo Ferreira; Secco, Deonir; Werncke, Ivan; Sarto, Marcos Vinícius MansanoThe objective of this study was to evaluate the dry matter (DM) yield and nutrient accumulation in cover crops and the effect of these, as well as mechanical management of crop residues on growth and grain yield of crambe (Crambe abyssinica). The experiment was conducted in Santa Helena, Paraná, Brazil in Rhodic Hapludox (Red Latosol in the Brazilian classification) in experimental design of randomized complete...
