1. Topdressing nitrogen fertilization associated with trinexapac-ethyl on industrial quality of oat grains
ABSTRACT Nitrogen fertilization, besides increasing productivity, can favor the production of well-formed, large, and heavy grains, which are traits valued by the oat processing industry. However, high nitrogen (N) doses may lead to plant lodging, which could be solved by using growth retardant. This study aimed to evaluate the industrial quality of white oa

2. Validation of white oat yield estimation models using vegetation indices
ABSTRACT The use of remote sensing in agriculture presents some practical applications in crop production forecast. In this context, studies with remote sensing are scarce for crops such as white oats, which may indicate the capacity of using this technique in the crop. The aim of this study was to evaluate the accuracy in validation of white oat biomass and

3. Biomass and nitrogen accumulation in white oat (Avena sativa L.) under water deficit
ABSTRACT Knowledge on nitrogen absorption rate by crops can indicate important managements, especially the definition of rates of this nutrient and the best time for topdressing application. This study aimed to evaluate and compare the accumulation of biomass and nitrogen in white oat cultivated under severe, moderate and no water deficit. Treatments consist

4. Growth and yield parameters of white oat and wheat as affected by canola residues
ABSTRACT Despite being an important crop option for Brazilian agriculture, canola has some characteristics that may limit its insertion in some cropping systems, such as its allelopathic effects. Thus, the present work aimed to study the effect of canola crop residues on the seed germination, growth and grain yield of white oat and wheat plants. In laborator

5. Uni- and multivariate methods applied to the study of the adaptability and stability of white oat
Resumo: O objetivo deste trabalho foi comparar o uso de métodos biométricos uni e multivariados na avaliação da adaptabilidade e da estabilidade de um importante grupo de cultivares de aveia-branca (Avena sativa), cultivadas no Sul do Brasil. Utilizou-se o delineamento experimental de blocos ao acaso, em arranjo fatorial 12 ambientes x 7 cultivares, com

6. Sampling Layer for Soil Fertility Evaluation in Long-Term No-Tillage Systems
ABSTRACT In no-tillage (NT) systems, there is no plowed layer since the soil is not tilled. Thus, the soil layer for fertility evaluation can be defined as the one in which the fertility indices are affected by the surface application of lime and fertilizers and soil properties have the closest relationship with crop yields. The objective of this study was t

7. Heterosis and genetic parameters for grain quality in oat segregating populations
ABSTRACT Improvement of quality-related traits of grains is a constant concern in white oat breeding programs, which challenges breeders to understand their dynamics. The performance of different genetic combinations must be thoroughly evaluated to make high nutritional quality cultivars available. This study aimed to estimate the heterosis on F1 and F2 gene

8. Pyricularia blast on white oats: a new threat to wheat cultivation
A newly emerged disease, the Pyricularia blast caused by Pyricularia grisea, is commonly observed on wheat and black oats, since its discovery in 1985. Within a few years the disease spread to other species of Gramineae, but white oat cultivars remained resistant and were the only ones among cultivated cereals resistant to this disease. In 2012, one commerci

9. DECOMPOSIÇÃO DE RESÍDUOS CULTURAIS DE PLANTAS DE COBERTURA DE SOLO E EMISSÕES DE ÓXIDO NITROSO / COVER CROPS RESIDUES DECOMPOSITION AND NITROUS OXIDE EMISSIONS
The inclusion of summer cover crops (SCC) in the no-till system is an interesting alternative to promote the addition of elevated quantities of plant biomass and nitrogen (N) to the soil. The C and N dynamics during the SCC residue decomposition can control the nitrous oxide (N2O) fluxes to the atmosphere. This study was carried out to quantify the SCC resid

10. FAEM Chiarasul: new white oat cultivar with high yield and grain-processing quality
The white oat cultivar FAEM Chiarasul was developed from a cross between UFRGS 17 and UFGS 10/ Coronado2/Cortez3/Pendek/ME 1563. It is characterized by reduced plant height, and high yield, grain quality and grain-processing quality.

11. Use of a conditioning unit at the haymaking of Tifton 85 overseeded with Avena sativa or Lolium multiflorum
White oat and ryegrass were overseeded on Tifton 85 pastures for evaluation of dry matter yield (DMY), leaf:stem ratio (L:S), dehydration curves and nutritional value of forages. Dry matter intake and L:S ratio were analyzed using a completely randomized blocks design with five forage growth conditions (single Tifton 85 and intercropped with white oat or rye

12. FAEM Carlasul: new white oat cultivar with high grain yield
The white oat cultivar FAEM Carlasul was developed at the Plant Genomics and Breeding Center, Faculty of Agronomy Eliseu Maciel, Federal University of Pelotas, as a result of the cross between UFRGS 10 and 90SAT-28 (Coronado2/Cortez3/Pendek/ME 1563). It is characterized by high yield and grain quality.
