Abstract
<p>The objectives of this study were to evaluate the optimum planting pattern of valley-type quinoa (Chenopodium quinoa Willd.) variety, Amarilla de Marangani and the relationship between dry matter production and seed yield. Field experiments were carried out in the experimental field at Nihon University in 2014, 2016 and 2017. In all years, the planting density was 100 plants m-2, and the intrarow width was from 6.67 cm (row width 15 cm) to 1.67 cm (row width 60 cm). The sowing time was September 3, 2014, August 31, 2016, and August 30, 2017. The seed yield was from 79.7 g m-2 to 273.2 g m-2. There were no significant differences in the seed yield among plots. The seed yield of this experiment was lower than that of the quinoa variety, NL-6 sown in March or April. One reason for this was the difference in the amount of solar radiation in the growing period. Seed yield and seed number were significantly correlated with the top dry weight at the flowering stage (seed yield r=0.746*, seed number r=0.756*). Thus, vigorous growth of the top until the flowering stage was needed to obtain higher seed yield of Amarilla de Marangani.</p>
