Description
Summary:Quinoa has great capacity to diversify agricultural production, due to its characteristics as functional food, rich in protein and fibers, besides having drought tolerance and high phenotypic plasticity. The objective of this study was to evaluate the effects of population arrangements and crop year on seed production and physiological potential of BRS Piabiru quinoa cultivar. The experiments were conducted in the experimental area of the Plant Science Department of the Federal University of Ceará, at the Pici Campus, in Fortaleza, CE, Brazil, for two agricultural years (2014/2015 and 2015/2016) under irrigated regime. The treatments resulted from a 3x3 factorial scheme (3 spacings between rows: 20, 40 and 60 cm, and 3 planting densities within the row: 10, 15 and 20 cm), and these treatments were distributed in four randomized blocks. The physiological tests of the seeds were carried out in the seed laboratory of the same institution. The 1000-seed weight, M%, GSI, MGT, G%, accelerated aging, panicle length and yield were evaluated. The seeds produced in the different planting arrangements showed high physiological quality, and the agricultural year was determinant. Increasing planting density reduced panicle size and increased yield of quinoa during the two cycles.
