Collard greens yield with mineral and organic fertilization

Abstract

The development of the collard greens crop was studied in the seedling phase and after planting in vessels, which received different treatments of fertilization which included mineral fertilizer (as standard), Bokashi compost (Bo) and EM4, earthworms humus (Hu), and piroligneous acid (AP), combined in ten treatments for each crop phase. The standard treatment included commercial substrate for seedlings (SC) and after planting with the formula 08-28-16. The length of the leaf was assessed 25 days after emergency. The leaf length and width was assessed 85 days after planting. The fresh and dry weight of leaf and petiole were assessed 144 days after seedling. Inferior development was observed in plants with humus. In general, in the treatments which included Bokashi, the results were similar or close to the standard treatment.
