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. ...
Estimation of irrigated oats yield using spectral indices
(2019-08-20)
Spectral indices such as normalized difference vegetation index (NDVI) and Falker chlorophyll index (FCI) are valuable tools for estimating crop yield. However, there remains a need to define the best phenological stages ...
