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 nitrogen (N) plant tissue levels using midrib NO3-N concentration for cauliflower (Brassica oleracea L., var. Botrytis) during the growing season. Tissue samples for nitrate analysis were taken from cauliflower plants over a period of four growing seasons beginning at the 4 to 6 leaf stage of growth and biweekly through pre-harvest. The midrib from the most recently full sized leaf was sampled for NO3-N concentration determination.
