Effect of irrigation regime on yield and water productivity of wheat (Triticum aestivum L.) in the lowland area of Ethiopia

Discover Sustainability
Inadequate agricultural water management and insufficient knowledge of proper irrigation scheduling are major constraints to wheat productivity under irrigation in Ethiopia. To address these challenges, this study aimed to evaluate the effects of varying

On‐Farm Demonstration and Economic Evaluation of an IoT Sensing System for Irrigation Management in South Carolina

Irrigation and Drainage, EarlyView.
ABSTRACT Irrigation can strongly influence agricultural productivity and sustainability. While sensor‐based irrigation has the potential to improve yield, reduce input costs and enhance resource‐use efficiency, its adoption in commercial agriculture remains limited.

Evaluating Water–Energy–Food Nexus Strategies to Address Resource Scarcity in the Crocodile River Catchment, South Africa

Irrigation and Drainage, EarlyView.
ABSTRACT The water–energy–food (WEF) nexus approach highlights the interdependence of water, energy and food resources, all of which play central roles in agriculture, especially irrigation. A WEF nexus lens was applied to Mpumalanga's Crocodile River catchment, a vital irrigation area that significantly contributes to South Africa's staple food ...

Remote Sensing for Irrigation Water Management—The State of the Art and Prospects for Near‐Future Operations

Irrigation and Drainage, EarlyView.
ABSTRACT A recent UN report describes many regions as facing ‘water bankruptcy,’ a condition in which available water resources can no longer meet existing demands. In practice, this means irrigation will likely bear the greatest burden of future water‐use reductions, a complicated and fraught decision to make given its critical role in food security ...

Comparison of different reference evapotranspiration (ET0) models and determination of crop-coefficients of french bean (Phesiolus vulgaris.) in mid hill region of Meghalaya

Journal of Agrometeorology, 2017
The water requirement and crop evapotranspiration (ETc)is determined using reference evapotranspiration (ET0) and crop-coefficient (kc). Numerous models are available for estimation of ET0,among which Penman-Monteith (FAO-56) model is considered to be ...

Transforming Agricultural Water Management for Healthy People and Planet: Thinking Beyond Water

Irrigation and Drainage, EarlyView.
ABSTRACT This paper develops the concept of Thinking Beyond Water, a transdisciplinary paradigm that reframes agricultural water management (AWM) as a systems catalyst for planetary health, equity, justice and resilience. Moving beyond conventional irrigation‐centric models, we reimagine AWM through integrative frameworks such as the planetary ...

Land‐Atmosphere Coupling Is Associated With Severer Vegetation Productivity Losses During Compound Dry‐Hot Events in Drylands

International Journal of Climatology, EarlyView.
Compound dry‐hot events (CDHEs) exerted severer damage on vegetation productivity for temperate shrublands, savannas and grasslands in drylands. Land‐atmosphere coupling was associated with severer negative impacts of CDHEs through soil moisture–temperature feedback, especially for dry‐event‐leading CDHEs.

An easily implemented agro-hydrological procedure with dynamic root simulation for water transfer in the crop–soil system: validation and application [PDF]

, 2009
Models for water transfer in the crop–soil system are key components of agro-hydrological models for irrigation, fertilizer and pesticide practices. Many of the hydrological models for water transfer in the crop–soil system are either too approximate due

Long‐Term Analysis of Winter Wheat Yield and Climatic Influences in Ukraine

International Journal of Climatology, EarlyView.
Long‐term field data (1968–2024) show that winter wheat yields in central Ukraine increased despite warming, but yield stability declined. Rising temperatures, more frequent soil moisture droughts and shortened winter calm increasingly limit productivity.
