VASCONCELOS, Fernando Soares de; VASCONCELOS, Edmar Soares de; BALAN, Marcelo Gonçalves and SILVERIO, Lucas. Development and productivity of quinoa sown on different dates the during off-season. Rev. Ciênc. Agron. [online]. 2012, vol.43, n.3, pp.510-515. ISSN 1806-6690. http://dx.doi.org/10.1590/S1806-66902012000300013.
This work was carried out with the aim of evaluating the development and productivity of the BRS-Piabiru variety of quinoa when sown on different dates during the off-season at Campo Mourao, PR. Six sowing dates were evaluated, namely: March 18, 2008; April 2, 2008; April 17, 2008; May 2, 2008; May 17, 2008; and June 10, 2008. The culture indices evaluated were the number of days to flowering, the number of days to maturity, plant height at maturity, and productivity. The experiment was conducted in a complete-block design with random treatments and four replications. The results indicate that the seeding date had an influence on the number of days to flowering, number of days to maturity, plant height at maturity, and productivity. The greatest plant height, together with the highest productivity for quinoa were obtained on March 18.
