Abstract
Plant analysis has been used to evaluate the nutritional status of many crops for diagnostic and corrective purposes. This study was initiated to establish critical N plant tissue levels using midrib NO3-N concentration for broccoli (Brassica oleracea L., Botrytis group) during the growing season. Tissue samples for nitrate analysis were taken from broccoli plants over a period of three growing seasons beginning at the 4 to 6 leaf stage of growth and biweekly through pre-harvest. The midrib from the most recently matured leaf was sampled for NO3-N concentration determination.
