“…Although the stability analysis has been more employed in the identification of genotypes with predictable behavior, it has been used in the definition of management technologies that ensure efficiency and stability in cultivation systems (Krüger et al, 2011;Silva et al, 2015). Studies of this nature were conducted in wheat for the identification of the best period of N application in favorable and unfavorable years (Arenhardt et al, 2015) and for the definition of the best plant arrangement on harvest uniformity and grain yield of canola (Krüger et al, 2016).…”

“…However, the expectation for high yields, especially under unfavorable climatic conditions for cultivation, can increase the doses of mineral fertilization, increasing the production costs and making the crop economically unviable (Foulkes et al, 2009;Barraclough et al, 2010). Furthermore, it can cause environmental damages through nitrate leaching or ammonia volatilization in the use of the fertilizer under limiting conditions of rainfall or heat (Ma et al, 2010;Arenhardt et al, 2015). The type of cover on the soil can reduce the losses through leaching or volatilization and N use efficiency (Ma et al, 2010;Viola et al, 2013).…”

“…Years with favorable and unfavorable weather and the conditions involving the systems of succession of high and reduced residual-N release alter N availability and use efficiency by the plant, leading to greater instability of yield (Espindula et al, 2010;Arenhardt et al, 2015). Hence, studies aiming at higher N use efficiency can qualify the recommendations and provide technologies that are more adjusted, economically viable and of lower environmental impact, which are decisive conditions in the search for a more sustainable agriculture (Parry et al, 2011;Prando et al, 2013).…”

A B S T R A C TNitrogen (N) is the nutrient most absorbed by the oat crop. Unfavorable climate conditions decrease its efficiency, generating instability and reduction in yield. The objective of this study was to improve N use efficiency in oat grain yield by the economic value of the product and of the input and by models that scale the stability, considering systems of succession of high and reduced residual-N release in favorable and unfavorable years for cultivation. The study was conducted in the years 2013, 2014 and 2015 in two systems of succession (soybean/oat, maize/oat) in randomized blocks with eight replicates, using the N-fertilizer doses of 0, 30, 60 and 120 kg ha -1 . The N-fertilizer dose for maximum economic efficiency in oats should be considered based on the meteorological trends of the cultivation year. N use optimization by models that determine the stability is an innovative proposal to increase fertilization efficiency on the yield. The N-fertilizer dose of 60 kg ha -1 promotes greater efficiency with predictability and yield, regardless of the agricultural year and the system of succession.A eficiência do nitrogênio em aveia na produtividade de grãos com estabilidade R E S U M O O nitrogênio é o nutriente mais absorvido pela aveia; em condições climáticas desfavoráveis diminui sua eficiência, gerando redução e instabilidade na produtividade. Objetivou-se, no estudo, a melhoria da eficiência de uso do nitrogênio na produtividade de grãos de aveia pelo valor econômico do produto e do insumo e por modelos que dimensionam a estabilidade considerando sistemas de sucessão de alta e reduzida liberação de N-residual em anos favoráveis e desfavoráveis ao cultivo. O estudo foi conduzido nos anos de 2013, 2014 e 2015 em dois sistemas de sucessão (soja/aveia; milho/aveia) em delineamento experimental de blocos casualizados com oito repetições, para as doses de N-fertilizante de 0, 30, 60 e 120 kg ha -1 . A dose de N-fertilizante pela máxima eficiência econômica em aveia deve ser considerada observando-se as tendências meteorológicas do ano de cultivo. A otimização de uso do nitrogênio por modelos que determinam a estabilidade é uma proposta inovadora para aumentar a eficiência de adubação sobre a produtividade. A dose de 60 kg ha -1 de N-fertilizante promove a maior eficiência com previsibilidade e produtividade, independente de ano agrícola e do sistema de sucessão.

“…The use of fertilizer-N is essential to maximizing the yield and quality of grains required by the industry (Mantai et al, 2015). Although the use of fertilizer-N increases oat biomass and grain yield in favorable years, high doses may lead to lodging, compromising grain production and quality (Arenhardt et al, 2015). In unfavorable years, yield losses can occur through leaching or volatilization of the nutrient, increasing costs and generating environmental pollution (Flores et al, 2013;Krüger et al, 2014).…”

The retainers of water in the soil can favor nitrogen (N) use efficiency in oat yield. The aim of the study was to determine if the conditions of use of the biopolymer hydrogel increase the fertilizer-N use efficiency in oat yield in succession systems of high and low residual-N release. In each succession system (soybean/oat, corn/oat), two experiments were conducted in 2014 and 2015, one to quantify biomass yield and the other to estimate grain yield and lodging. The design was randomized blocks with four replicates in a 4 x 4 factorial scheme for hydrogel doses (0, 30, 60 and 120 kg ha-1), added in the furrow with the seed, and N fertilizer doses (0, 30, 60 and 120 kg ha-1) applied in the fourth-expanded-leaf stage. The use of hydrogel increases N use efficiency in oat yield, especially under the conditions of 30 to 60 kg ha-1 of biopolymer; however, this effect is dependent on the succession system and on weather conditions.

White oat (Avena sativa L.) is a cold season grass, with a very important role, both in animal and human food, due to the chemical composition of its grains, which have, among other beneficial components, fiber soluble food products, beta‐glucans. Therefore, the demand for grains of the crop is maximized and it is important to increase grain production. This can be achieved through the adequate positioning of the genotypes in the growing environments to maximize the agronomic performance of the crop. Thus, the objective of this work was to decompose meteorological and geographic variables in the positioning of white oat genotypes. The study took place considering 39 genotypes of white oats in 21 environments (in 13 years), in six municipalities of Rio Grande do Sul, two locations in the state of Santa Catarina, ten in Paraná and three municipalities in the state of São Paulo. The average grain yield (kg ha−1) of the genotypes in each environment was used to determine the adaptability and stability of the genotypes through the application of the Genotype and Genotypes by Environments Interaction (GGE biplot) biometric method and the reaction norm. The reaction norm pointed out that the genotypes UPFPS Farroupilha, UPFA Gaudéria and URS Guará demonstrated general adaptability to all environments, while FAEM 006 and URS Charrua expressed stability, high grain yield and higher than average genetic value. The GGE biplot graphically demonstrated that the genotypes URS Monarca and IPR Artemis demonstrated the highest grain yield and high stability in the environments Eldorado do Sul ‐ RS (E7) and Pelotas ‐ RS. Identifying genotypes with superior agronomic performance in specific environments minimizes the effects of genotype x environment interaction. These white oat genotypes can be used as sources of alleles for the development of new genotypes.This article is protected by copyright. All rights reserved
