Chlorophyll Measurements and Nitrogen Nutrition Index for the Evaluation of Corn Nitrogen Status

2008-09-01

Abstract excerpt

Plant-based diagnostic techniques are used to determine the level of crop N nutrition but there is limited comparative research on the different methods. Our objectives were to establish the relationship between chlorophyll meter (CM) readings and N nutrition index (NNI) during the corn (Zea mays L.) growing season, and to compare both methods as diagnostic tools for predicting grain yield response to N fertilizat...
