Simulation of Growth and Development of Tomato (Lycopersicon esculentum Mill.) under Drought Stress: 1- Simulation of Soil Water Content, Evapotranspiration, and Green Canopy Cover

E. Farrokhi; M. Nassiri Mahallati; A. Koocheki; alireza beheshti

Volume 35, Issue 3 , July and August 2021, Pages 299-318


  Introduction: The modeling approach for the simulation of the growth and development of tomatoes in Iran has been overlooked. Calibrated crop simulation models, therefore, are increasingly being used as an alternative means for the rapid assessment of water-limited crop yield over a wide range of environmental ...  Read More

Investigation of the Intra-Seasonal Sensitivity of Maize Evapotranspiration to Water Stress, at Different Irrigation Levels

R. Saeidi

Volume 35, Issue 3 , July and August 2021, Pages 335-348


  Introduction: Adeqiate water use in the agricultural sector requires accurate knowledge of crop sensitivity to environmental stresses (such as water stress). The crop sensitivity to water stress may be different at different growth stages and may have a different effect on the actual amount of crop evapotranspiration ...  Read More

Optimization of Cropping Pattern through Groundwater Resources Management Using D.E. and PSO Algorithms

M. Komasi; A. Alizadefard

Volume 35, Issue 3 , July and August 2021, Pages 349-364


  Introduction: The occurrence of successive droughts, along with increasing water needs and lack of proper management of water resources has caused a water crisis that has various environmental and economic consequences. In addition to the drought, the change in the cropping pattern towards water crops ...  Read More
