| This work was aimed with the objective to evaluated quinoa genotypes in the Marechal Cândido Rondon, Paraná State. It was sown eight varieties of quinoa, from the Genetic Improvement Program of Quinoa of the Unioeste, with three repetitions, in a total number of 24 parcels. The experimental units were constituted of four lines of 5 meters each and with a row spacing of 0.5 meter between each other resulting at 4 m2 of utile area. The treatments during growing were made whenever they were necessary, with the use of manual weed, herbicides and fungicides. The assessed variables were a flowering date, maturity date, average height of ten plants per parcel and the productivity. The genotypes used in this experiment have cycle and height plants near recognized... |

| This study aimed to evaluate the effect of the integrated crop-livestock system on the contents and stocks of total organic carbon, total nitrogen, and soil organic matter. The experiment was carried out between April 2016 and February 2017, in a randomized block design in a strip-block scheme, with additional control treatment (fallow) and four repetitions. The treatments consisted of two densities of oat sowing (40 and 60 kg ha-1) in strips A and different grazing frequencies (without grazing - WG, one grazing - 1G, and two grazing - 2G) in strips B, besides fallow as a control treatment. The determinations of the contents of total organic carbon (TOC), total nitrogen (TN), and organic matter (SOM) were carried out in the soil layers of 0-5, 5-10, and... |

| The main cause of decreased soil fertility and soil organic matter content is intensive crop farming with inadequate management. This study aimed to evaluate soil chemical properties, total organic carbon content, physical granulometric fractions (particulate organic carbon and mineral-associated organic carbon), carbon stocks, and carbon management indices of oxisols in different integrated agricultural production systems (IAPSs) with reference to values in a haymaking area and native forest. The experiments were performed using completely randomized design, considering nine differently managed areas, including seven IAPSs and two reference areas (haymaking area and native forest); four soil samples from the 0.00-0.05, 0.05-0.10, and 0.10-0.20 m layers... |

| This study aimed to evaluate the decomposition and release of nutrients from the remaining straw of two annual forage species conducted in an integrated crop-livestock system (ICLS). The experimental design used was randomized blocks, in split plots, with three replicates. The managements were allocated in the plots (52 m2): without grazing, one grazing, and two grazings. Subplots were defined by material collection times after the forage’s desiccation (0, 30, 60, 90, and 120 days after desiccation). Dry matter yield, amounts of carbon, nitrogen, phosphorus, and potassium, and half-life time were evaluated. Oat cultivar IPR Esmeralda had the highest initial dry matter yield (6,099 kg ha-1) when not grazed, while triticale cultivar IPR 111 showed the... |

| This research aimed to identify the floristic composition of weed communities present in the agricultural area, cultivated with winter cereals and managed under integrated crop livestock. The study was conducted in the experimental area of the Western Paraná State University, Campus Marechal Cândido Rondon, in EUTRUSTOX Eutrophic, with a randomized block design in bands, with four replications. The treatments consisted of three different winter cereals (oats IPR 126, triticale IPR 111 and wheat BRS Tarumã) with different managements: ungrazed, one grazing and two grazings. The grazing was done in two days, until the residual height of 15 cm of each forage, using Holstein cows. The phytosociological survey was conducted in each plot 20 days after harvest... |

| Os sistemas integrados de produção lavoura-pecuária (SIPAs) em associação ao sistema de semeadura direta, sofrem ação do pisoteio animal ou do tráfego intenso de máquinas agrícolas, podendo resultar em alterações nas propriedades físicas do solo. O objetivo deste trabalho foi avaliar o efeito da adubação nitrogenada e manejos das forrageiras tropicais nas propriedades físicas do solo. O experimento foi realizado entre outubro de 2017 e janeiro de 2020, em Marechal Cândido Rondon – PR, em blocos ao acaso, com parcelas sub-subdivididas com uma testemunha adicional e quatro repetições. As parcelas foram constituídas por duas espécies forrageiras consorciadas com o milho: Urochloa brizantha e Magathyrsus maximum, mais a testemunha adicional (milho solteiro).... |
