Evaluación del efecto de dosis crecientes de nitrato sobre la actividad de la reductasa del nitrato; nitrógeno derivado del fertilizante en cafeto
Defficient Coffea arabica L. plants were treated with CaNO, (114%15N) in doses ranging from 25 to 200 kg/ha of N The effect of the treatments on the activity of nitrate reductase and on Nitrate Assimilation Potential was evaluated. Both parameters were equally sensitive to the nutritional status of...
