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 ...
Software for the management of weather stations and for agrometeorological calculations
(2015-01-01)
Surface weather stations in agricultural areas are commonly managed non-professionally, usually in areas with more than one station. Climate is defined as the average meteorological conditions of a region, and knowledge ...
Root distribution, nutrient uptake, and yield of two upland rice cultivars under two water regimes
(2013-01-31)
Upland rice (Oryza sativa L.) cultivation has been increasing in global importance due to the decreasing water availability for flood- irrigated rice. The use of sprinkler irrigation to supplement rainfall and the ...

Agrometeorological models for forecasting yield and quality of sugarcane
(2015-01-01)
Climate is an important factor in sugarcane production, and its study is fundamental for understanding the climatic requirements of the crop. We developed regional agro-meteorological models to forecast monthly yields in ...
Least limiting water range and crop yields as affected by crop rotations and tillage
(Wiley-Blackwell Publishing, Inc, 2010-12-01)
Crop rotation and the maintenance of plant residues over the soil can increase soil water storage capacity. Root access to water and nutrients depends on soil physical characteristics that may be expressed in the Least ...
