Mashua's pest-repellent compounds protect ulluco from nematodes and insects; this traditional Andean pairing provides mutual protection and efficient land use.
Ulluco and oca are traditional Andean polyculture partners , ulluco's waxy tubers form at different soil depth than oca, maximizing yield per square foot.
Andean companion crops with different harvest windows
Quinoa grows tall above ulluco's low-spreading foliage; ulluco creates living mulch that conserves soil moisture for quinoa's shallow roots.
Broad beans fix nitrogen that feeds ulluco's tuber production; ulluco's groundcover suppresses weeds around bean plants , a productive Andean intercrop.
