Summary

This 2016 field trial evaluated transplanting versus direct-seeding methods for quinoa production on two farms in Washington's Olympic Peninsula. Transplanted quinoa demonstrated higher survival rates, faster maturation, and superior yields compared to direct-seeded crops, though transplants exhibited increased lodging despite being more branched and shorter. The findings suggest transplanting offers an improved production method suited to urban and peri-urban quinoa growers with existing transplant infrastructure.

UK applicability

Quinoa cultivation remains marginal in the United Kingdom climate; however, the transplant methodology could inform UK horticulturists exploring alternative crop production in protected or favourable microclimates. The weed-control and maturation benefits may be particularly relevant for smaller-scale and urban UK growers.

Key measures

Plant survival rates, developmental stage timing, seed yields, plant branching and height, lodging rates, yield comparisons across planting dates

Outcomes reported

The study compared transplanting and direct-seeding methods for quinoa across three varieties and multiple planting dates on farms in western Washington state, measuring survival rates, plant morphology, lodging incidence, and seed yield outcomes.
