Quinoa is not जौ, and neither it is any of the grains they are talking about in that article, Buckwheat is फापर and Cheeno is similar to corn, but it's definitely not Quinoa. I forgot the Nepali name, but a Cheeno plant is usually taller and skinnier than a corn plant, and the grains are also smaller (about 1/3 to 1/2 the size of a corn seed). 

I'm not 100% sure but Quinoa is called लट्टे in Nepali.
