Abstract

Brassica chinensis var. parachinensis is a vegetable with short cycle, which was introduced in Brazil in 1992 due to its high nutritional qualities. It presents high concentration of β-carotene, vitamin C, Ca, and Fe, becoming an important food for the prevention of anemia. The aim of this paper was to evaluate the biological and agronomic productivity of plants grown under N, P, K, Ca, Mg, S, B, Cu, Fe, Mn, Mo, and Zn deficiency. The results were compared with plants grown with all macro and micronutrients. Plants cultured without N and P completed their cycle, but had lower yield than those cultured with complete nutrition. Additionally, they had green-grayish leaves, and purple petiole and veins. Plants cultured without B died between 30 and 37 days after sowing, and without S they did not produce fruits. These results show the importance of S and B to this Brassicaceae.
