Agrometeorological models for forecasting the qualitative attributes of “Valência” oranges
(2017-11-01)
Forecasting is the act of predicting unknown future events using available data. Estimating, in contrast, uses data to simulate an actual condition. Brazil is the world’s largest producer of oranges, and the state of São ...
Forecasting of the annual yield of Arabic coffee using water deficiency
(Empresa Brasil Pesq Agropec, 2018-12-01)
The objective of this work was to develop agrometeorological models for the forecasting of the annual yields of Arabic coffee (Coffea arabica), using monthly water deficits (DEFs) during the coffee cycle, in important ...
Spectral agrometeorological modeling adapted by means of simplified triangle method for soybean in paraná state – Brazil
(2018-05-01)
Agriculture is an economic activity with high dependence on weather and climate. Special geotechnology and agrometeorological modeling can be used to optimize productivity in regional and national systems, while minimizing ...
Dry matter production of Tanzania grass as a function of agrometeorological variables
(EMPRESA BRASIL PESQ AGROPECBRASILIA DF, 2012)
The objective of this work was to develop and validate linear regression models to estimate the production of dry matter by Tanzania grass (Megathyrsus maximus, cultivar Tanzania) as a function of agrometeorological ...
Influence of El Niño and La Niña on sugarcane yield and sucrose production in northern São Paulo, Brazil
(2015-01-01)
The El Niño Southern Oscillation (ENSO) influences the global agriculture globally, with complex effects on crop yields in the state of São Paulo in Brazil. We assessed the effects of ENSO on the yield of sugarcane (Saccharum ...
Agrometeorological models to forecast açaí (Euterpe oleracea Mart.) yield in the Eastern Amazon
(2020-03-15)
BACKGROUND: The increasing demand in Brazil and the world for products derived from the açaí palm (Euterpe oleracea Mart) has generated changes in its production process, principally due to the necessity of maintaining ...
Adaptation of a leaf wetness duration model for tomato under Colombian greenhouse conditions
Greenhouse tomato production uses structures that protect
crops from extreme environmental conditions; however, the
climate inside Colombian greenhouses is often not optimal and
crops are susceptible to attack by fungal ...
Simple agrometeorological models for estimating Guineagrass yield in Southeast Brazil
(Springer, 2014-09-01)
The objective of this work was to develop and evaluate agrometeorological models to simulate the production of Guineagrass. For this purpose, we used forage yield from 54 growing periods between December 2004-January 2007 ...
Agrometeorological models for forecasting coffee yield
(2017-01-01)
Some forecasting techniques have been tested with crop models using various statistical analyses for generating future scenarios of yield (Y). Forecasting, however, can be achieved by simply using regression analysis and ...
