EFFECTS OF ADDED NITROGEN, PHOSPHORUS, AND POTASSIUM ON LEAF TISSUE BORON CONCENTRATION OF THREE VEGETABLE CROPS

Abstract

The effects of various rates of nitrogen, phosphorus, and potassium on the boron concentration of leaf tissue of cauliflower (Brassica oleracea var. botrytis L. ’Snowball Y’), Brussels sprouts (Brassica oleracea var. gemmifera Zenker ’Jade Cross’) and peas (Pisum sativum L. ’Dark Skin Perfection’) were investigated at several locations in Prince Edward Island. Except for N on cauliflower, B concentrations of leaf tissues of these crops were not greatly affected by the N, P, or K treatments. Applied N increased the B concentration of cauliflower leaf tissue at eight of the nine locations investigated.
