- Abstract
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.
