Both developing and developed countries have problems with availability of water to increase agricultural productivity. The importance of improving water efficiency in agriculture has been the subject in many research papers. The usual approach to limit water consumption in agriculture at the district and farm level is to apply water quotas. These quotas may be either for the whole season or fo...

In preparation for active microwave-based data assimilation into a crop modeling system, the mapping of daily 1-km AquaCrop model (v6.1) biomass and surface soil moisture to backscatter was optimised, using two forward operators, i.e. Water Cloud Model (WCM) Support Vector Regression (SVR). Both operators were calibrated (2014–2018) with Sentinel-1 (γ°) observations in VV VH polarisation, three...

the growth and development of crop models such as aquacrop model is the most important tools for decision-making and predicting crop yields. the aim of this research was to assess aquacrop model for simulating spatial variability of forage maize yield along the furrow. four treatments for calibration and validation of the model were investigated based on the percentage of supplied crop water re...

in this study, the performance of aquacrop model to predict yield production of winter wheat (roshan and gods varieties), water and solute balance of soil profile was evaluated under water and salinity stresses. field experiments were conducted with three levels of saline irrigation water including: s1, s2 and s3corresponding to 1.4, 4.5 and 9.6 ds/m, respectively, and four levels of irrigation...

In Algeria, vegetable crops are dependent on irrigation. this context, the present study is oriented towards efficient management of agricultural water that contributes to improvement crop production. The approach based calculation requirements potato in order control efficiency supply relation requirements. This use imperative for a better yield and healthy environment. study, we used two agro...
