Preliminary evaluation of coffee crops under different doses of nitrogen with a spad meter and leaf nitrogen.

Abstract: The objective of this study was to establish correlations among the total N and the SPAD read- ings in Coffea arabica leaves. This study is part of a project that aims to evaluate the agronomic and environmental efficiency of nitrate-based fertilizers compared to conventional nitrogen fertilizers used in the cultivation of coffee.
