RESIDUAL EFFECTS OF NITROGEN FERTILIZER WITH POLYMER-COATED UREA IN A CORN CROP
(Univ Fed Rural Semi-arido-ufersa, 2017-07-01)
The use of nitrogenous fertilizer coated by polymers may reduce losses caused by volatilization, thus exposing this element to plants for a longer period of time. The objective of this work was to evaluate the residual ...
Analysis of yield response variability to nitrogen fertilization in experiments performed in the Argentine Pampas
(Taylor & Francis, 2008-12)
Nitrogen (N) fertilization has become a common practice in corn and wheat crops in the Argentine Pampas during the past decade. In this region, great environmental variability determines erratic responses to fertilization. ...

Influence of nitrogen fertilization on the characteristics of potato starch
This study evaluated the effect of nitrogen fertilization rates on the characteristics of potato starch. The experimental design was randomized block with four replications. The treatments were composed of four rates of N ...
WINTER BEAN PRODUCTIVITY UNDER UROCHLOA STRAW FERTILIZED WITH NITROGEN
(Univ Fed Rural Semi-arido-ufersa, 2016-01-01)
An experiment was conducted during the years 2009 and 2010 to evaluate the effects of Urochloa forage straw and nitrogen fertilization on soil properties, nutritional foliar content, index of foliar chlorophyll (IFC) values, ...
