RELATIONS BETWEEN THE SPAD INDEX DETERMINED BY CHLROPHYLL METER WITH NITROGEN CONTENT IN LEAVES AND GRAIN YIELD IN MAIZE GENOTYPES

RELATIONS BETWEEN THE SPAD INDEX DETERMINED BY CHLROPHYLL METER WITH NITROGEN CONTENT IN LEAVES AND GRAIN YIELD IN MAIZE GENOTYPES

The objective of this work was to evaluate the accuracy of the chlorophyll meter readings (SPAD index) for early assessing nitrogen content on maize leaves and to proportionate subsidies for recommending nitrogen fertilization. The assay was carried out with three simple maize hybrids (DKA333B, P32R...
