Título: Levantamento de parâmetros de solo para qualificação de lavouras de soja no município de São Francisco de Assis - RS
Resumo em Língua Estrangeira: The increase in the world population has been impacts the world annual demand for
soybeans, due to its high levels of proteins and lipids. However, we have finite
resources, and the soil use needs to be more efficient to increase productivity and
profitability. Considering it, here we try to understand the main soil parameters and the
types of management that may interfere with soybean productivity, thus better
visualizing the factors that may be limiting. Therefore, a questionnaire was prepared a
and applied, between February and August 2020, to 29 producers of São Francisco
de Assis who had their soil chemically analyzed during the harvests of 2017/2018,
2018/2019 and 2019/2020. After analyzing the data, the main conclusions observed
are that, regardless of the year, which had quite different rainfall levels, the highest
yields are achieved by producers who have better pH, base saturation and aluminum
levels. These directly impact the soil's ability to provide nutrients. In years of low
rainfall, these items are even more important, especially if combined with organic
matter.

Título: Aplicação de fungicida em diferentes estádios fenológicos na cultura do milho safrinha
Resumo em Língua Estrangeira: The objective of this work was to evaluate the efficiency and number of
fungicide applications at different phenological stages on off-season corn
performance, with emphasis on yield. The experiment was conducted from
February 18, 2020 to August 4, 2020, in a commercial field, where plots 30
meters long by 28 meters wide were demarcated, each plot 30 meters long with
8 rows of planting, with spacing of 0.5 m, totaling 120 m2. Fungicide applications
were carried out at phenological stages V8; VT; R2; V8 + VT; VT + R2 and V8 + VT
+ R2. In the control treatment, no fungicide application was carried out. The
product used was the fungicide containing Fluxapiroxade and Piraclostrobin, at
a dose of 350 ml.ha-1
. After harvesting and weighing it can be verified that the
plots with a fungicide application in the vegetative stages V8 and VT were the
most productive and most profitable in relation to the control where no
application was made. Plots where two and three fungicide applications were
made did not obtain satisfactory production or profitability.

Título: Adoção da agricultura de precisão na fronteira oeste do Rio Grande do Sul
Resumo em Língua Estrangeira: Agribusiness management studies the profile and characteristics, of farmers on
the Western Frontier of Rio Grande do Sul (RS), adept or partially adept at the
technologies that are part of Precision Agriculture (PA). This is an exploratory,
descriptive, opinion survey with non-probabilistic sampling, comprising 25 farmers from
5 cities in the Western Frontier of RS, comprising 113,118 ha hectares, of which 66,040
ha are adept of PA. The interviews allowed the correlation of qualitative and
quantitative data, generating important information. In this sense, the profile of the
properties under study has an average adhesion to PA of 75% of its area. The average
size of these properties is 4,525 ha, 54% of which is owned and 46% leased. The
predominant age group of PA supporters is 46 to 55 years old, representing 40% of
the sample population. The predominant level of education of the adopters of the PA
is Graduated, representing 52%. The main crops where PA tools are applied, in the
Western Frontier of RS, are soybean (39%) and rice (26%). The average time of
adoption of the PA in the Western Frontier is 5 years. The main intention of purchasing
machines and equipment with PA is the Vacuum Planter representing 28% of the
purchase intentions for the next 2 years.

Título: Manejo de adubação fosfatada na produtividade da cultura da soja
Resumo em Língua Estrangeira: Soybean (Glycine max (L.) is an of the most important crops for the world
economy. Its grains are widely used by the agribusiness (production of vegetable oil
and animal feed), chemical and food industry, as well as an alternative source of
biofuel. Brazil is the largest producer in the world, but there is an productivity gap to
be filled in. The content of phosphorus (P) available in the soil has been reported as
a more generalized nutritional limitation to agricultural production. This study aimed
was to evaluate the productivity of the soybean crop, submitted to different forms of
application of phosphate fertilizer TOP-PHOS® (3% de N; 28% de P; 17% de Ca e
7% de S). Treatments constituted in the follow application forms: Witness (without P),
P in the line and P to throw, in cultivar BMX ZEUS®. In the visual evaluation
performed at 24 days after emergence, where the P was placed in the line close to
the seeds (7 to 10 cm deep), there was a greater structuring of roots (volume and
length) and aerial part, proving greater productivity between treatments. The
treatment witnesses showing weakened plants, such as which had the lowest result
in grain yield. Although the management with P at haul overcome in productivity in
relation to the control, it did not achieve the same result as the management with P in
the sowing line. Thus, because it is a little mobile element in the soil, and highly
demanded by the soybean crop, the highest productivity is achieved when the
phosphorus is close as roots.
