Multiobjective Simulation–Optimization of Crop Allocation and Water Resources in Canal Command Areas Using Genetic Algorithms

Irrigation and Drainage, EarlyView.
ABSTRACT This study develops an integrated simulation–optimization framework for sustainable crop allocation and water resource management in the Bargarh Canal Command (BCC), eastern India. Efficient irrigation allocation remains a critical challenge due to competing demands, groundwater–surface water interactions and environmental constraints ...

Possibilité de déduction des besoins en eau d'irrigation à partir de la loi de dessèchement du sol [PDF]

La Houille Blanche, 1967
Since the notion of evapotranspiration of a soil and plant system and methods for the determination of both potential and 'effective' evapotranspiration (Ep and E respectively) have been gaining popularity, criteria have been suggested for the calculation of theoretical water applications for farmland requiring irrigation from these values.

Machine Learning‐Based Estimation of Reference Evapotranspiration and Crop Coefficients for Wheat Under Diverse Climatic Conditions

Irrigation and Drainage, EarlyView.
ABSTRACT Accurate estimation of reference evapotranspiration (ET0) and crop coefficients (Kc) is critical for irrigation planning, particularly in data‐limited regions where agriculture dominates freshwater consumption. Although machine learning (ML) methods have been widely applied to ET0 and Kc estimation, most studies address these parameters ...

Drivers and Challenges of Micro‐Irrigation Adoption and Intensity in India: A Study of Four States

Irrigation and Drainage, EarlyView.
ABSTRACT India's food security relies substantially on groundwater, but inefficient irrigation is seriously depleting this resource. Micro‐irrigation (MI) improves irrigation application efficiency and productivity, yet adoption remains low. This study examines MI adoption across four major Indian states—Uttar Pradesh, Maharashtra, Madhya Pradesh and ...

Variable Rate Irrigation: A Long‐Term Simulated and Field Data Analyses of Irrigation Practices, Field Variability, Economic Feasibility and Profitability

Irrigation and Drainage, EarlyView.
ABSTRACT Long‐term economic analyses of variable rate irrigation (VRI) strategies were performed compared with uniform irrigation management (UIM) in a reference production field using the AquaCrop model. Five strategies to trigger irrigation were as follows: (Field Capacity‐VRI, Driest Soil Trigger‐VRI, Water Mining‐VRI, Conventional Uniform ...

Inline Oxygenation in Drip‐Irrigated Citrus: How Much Agrochemical Reduction Is Needed to Achieve Net Environmental Benefits?

Irrigation and Drainage, EarlyView.
ABSTRACT The agronomic benefits of oxygen‐enriched irrigation, such as improved root development, enhanced nutrient uptake, and reduced fertiliser and pesticide requirements, are well documented. However, incorporating oxygenation devices into fertigation systems increases energy demand and material use, thereby incurring additional environmental ...
