Yield estimations at global or regional spatial scales have been compromised due to poor crop model calibration. A methodology for estimating the genetic parameters related grain growth and yield CERES-Wheat is proposed based on gap concept, GLUE coefficient estimator, atlas (GYGA). trials with three durum wheat cultivars in an experimental farm northern Greece from 2004 2010 were used. The cal...

crop models need more evaluation and study for use in deficit irrigation. the main objective of this paper was to study the efficiency and accuracy of dssat model, in estimating of moisture in the soil profile under two levels of water application¬¬¬ in silage maize field. two irrigation treatments including deficit irrigation (0.7 smd), and a full irrigation (smd) were considered for two years...

Highlights CSM-NWheat, a DSSAT wheat crop model, was coupled with pest module named PEST. The model can simulate the impact of and disease damage on crops. Pest is expressed in daily steps by communication links called coupling points. Coupling points are linked state variables at which be applied. Field pest-scouting reports linear interpolation used to compute rates. Abstract . Wheat one most...
