Agronomic performance of cultivars of organic onion in two harvest times
The growing demand for organic products and the need to plant onions (Allium cepa L.) in the town of Pinhais, Brazil at different times of the year generated this study in the Organic Horticulture Experimental Station of Canguiri-Federal University of Parana, Pinhais, Brazil. The objective was to ev...
