Fertilizer Application
A good response in the crop has been observed with respect to the application
of nitrogenous fertilizers, but high levels of available nitrogen are reported to
decrease yield due to slow maturity and intense lodging (Oelke et al., 1992).
However, recent studies (Berti et al., 2000; Schulte auf’m Erley et al., 2005)
suggest that quinoa responds strongly to nitrogen fertilization and grain yield did
not show a decrease with increasing N rates. Jacobsen et al. (1994) observed
that quinoa grain yield increased with increasing nitrogen fertilization rate from
40 to 160 kg N/ha. Schulte auf’m Erley et al. (2005) assessed the response
