Concurrent Response of Soybean to Fixed (Full and Limited) and Variable Rate Irrigation Management in Three Soil Types: II. Growth, Yield, Evapotranspiration and Water Productivity

Irrigation and Drainage, Volume 74, Issue 5, Page 1874-1888, December 2025.
ABSTRACT Soybean growth, yield, crop evapotranspiration (ETc) and crop water use efficiency (CWUE or crop water productivity, CWP) under different irrigation levels in three different soil types in the same field were investigated concurrently. Treatments in each soil type were: (i) variable rate irrigation (VRI), (ii) fixed rate full irrigation (FR‐1″)

Concurrent Response of Soybean to Fixed‐ (Full and Limited) and Variable‐Rate Irrigation Management in Three Soil Types: I. Soil Water Dynamics

Irrigation and Drainage, Volume 74, Issue 5, Page 1853-1873, December 2025.
ABSTRACT This research investigated soybean soil water dynamics under different irrigation levels in three different soil types in the same field concurrently. Treatments imposed in each soil type were: (i) variable‐rate irrigation (VRI), (ii) fixed‐rate full irrigation (FRI‐1″ or FRI‐25.4 mm) and (iii) fixed‐rate limited irrigation (FRI‐0.75″ or FRI ...

Agronomic Performance and Water Use Indicators of Cactus Species Widely Cultivated in Semiarid Regions

Irrigation and Drainage, Volume 74, Issue 5, Page 2156-2173, December 2025.
ABSTRACT This study aimed to evaluate the agronomic performance, crop evapotranspiration (ETc), crop coefficients (Kc, Kcb and Ke) and yield response factor (Ky) of three forage cactus clones—Orelha de Elefante Mexicana (OEM), Miúda (MIU) and IPA Sertânia (IPA)—grown in a semiarid environment.

Can Solar‐Powered Irrigation Systems Naturally Meet Crop Water Requirements? Proof of Concept From a Case Study in Sub‐Saharan Africa

Irrigation and Drainage, Volume 74, Issue 4, Page 1423-1435, October 2025.
ABSTRACT Irrigation scheduling is crucial for ensuring precise water delivery to crops. However, in many sub‐Saharan African irrigation schemes, water is applied without considering crop water needs, resulting in low crop water productivity and low yields. Solar‐powered irrigation systems can automatically meet these needs by utilizing solar radiation,
