“…Oats are a widely grown winter crop in the South region of Brazil for grain production and soil cover (Mantai et al, 2020;Kraisig et al, 2020;Kraisig, et al, 2023). They are essential for animal feed, provided as fresh mass, dry mass, hay, or silage (Silva et al, 2020;Basso et al, 2022;Schmidt, et al 2023). Furthermore, oats are increasingly included in human diet due to their properties related to reductions in LDL cholesterol and, consequently, risk of cardiovascular diseases (Malanchen et al, 2019;Reginatto et al, 2021;Treter et al, 2023).…”

Technologies ensuring high crop yield and plant competitiveness without lodging can contribute to an efficient and sustainable management of oat crops. The objectives of this study were to evaluate the use of high seeding density in current oat cultivars grown in the northwestern Rio Grande do Sul (RS), Brazil; assess the effects of plant growth regulators on grain yield indicators, industrial grain quality, and stem structure; and evaluate a calcium and potassium-based organomineral product as a sustainable technology for controlling lodging. Two experiments were conducted in Augusto Pestana, RS, in a randomized block design. Experiment I (2021) was set up in a 4×3 factorial arrangement consisted of 4 oat seeding densities (100, 300, 600, and 900 seeds m-2) and 3 treatments with plant growth regulator (PGR) application (control; application of trinexapac-ethyl and organomineral product at the stage between the 1st and 2nd visible stem nodes). Experiment II (2022) was set up in a 4×4 factorial arrangement consisted of 4 seeding densities (100, 300, 600, and 900 seeds m-2) and 4 PGR application treatments (control; application of trinexapac-ethyl and organomineral product at the stage between the 1st and 2nd visible stem nodes; and sequential application of organomineral product at V4 and at the stage between the 1st and 2nd visible stem nodes). The results of both experiments showed the need for a higher seeding density (between 400 and 520 seeds m-2) than that recommended. High air temperatures and limiting soil water conditions increased the phytotoxic potential of trinexapac-ethyl in oat crops. Evaluations of the Ca and K-based organomineral product, as a sustainable technology for controlling plant lodging, requires further analysis in years with more favorable environmental conditions for oat crops.

Purpose: The objective of this study was to evaluate the population density of quinoa plants sown by broadcasting or in rows to improve agronomic indicators of an organic farming system focused on increasing food and nutrition security of the population. Method/design/approach: The study was conducted in 2020, in Augusto Pestana, RS, Brazil, using a randomized block experimental design with four replications, in a 2×4 factorial arrangement consisted of 2 sowing methods (sowing in rows spaced 0.20 m apart and by hand broadcasting) and 4 plant population densities (10, 40, 80, and 120 plants m-2). Thinning was performed in the plots of both sowing methods approximately 20 days after emergence for achieving the desired plant densities. Grain yield and other traits of agronomic interest were evaluated under an organic cropping system. Results and conclusion: The arrangement of 70 quinoa plants m-2 through sowing in rows or by broadcasting ensures satisfactory crop yields without using pesticides and synthetic fertilizers. The incorporation of these more sustainable practices into quinoa production systems contributes to the promotion of agroecological and organic agriculture, resulting in a high-quality nutraceutical food. Originality/value: This study provides significant contribution to the advancement of research on quinoa in Brazil, bringing new information benefiting farmers, technical assistance agents, and the food industry and improving the production system efficiency to ensure food and nutrition security and care for the environment and society.

Purpose: The objective of this study was to propose changes in sowing and plant population managements for chia crops under organic production system to improve agronomic characteristics and promote higher yields while ensuring environmental quality and nutrition safety. Method/design/approach: The study was conducted in Augusto Pestana, RS, Brazil, using a randomized block experimental design with four replications, in a 2×4 factorial arrangement consisted of 2 sowing methods (sowing in rows spaced 0.20 m apart and hand broadcasting) and 4 population densities (10, 40, 80, and 120 plants m-2). Plants in the plots of both sowing methods were thinned approximately 20 days after emergence to achieve the desired plant density. Grain yield and other agronomic characteristics of interest were evaluated under an organic cropping system. Results and conclusion: The arrangement of 55 chia plants m-2 through sowing in rows or by broadcasting ensures a satisfactory crop yield without using pesticides and synthetic fertilizers. The adoption of these more sustainable practices contributes to the improvement of agriculture quality and safety, yielding high-quality nutraceutical foods. Originality/value: This study provides a significant contribution to the advancement of research involving chia in Brazil, bringing new information that benefits farmers, technical assistance professionals, consumers, and the food industry, promoting nutrition safety, environmental protection, and the well-being of the population.
