Management Strategies and Agricultural Calendars for Forage Production in Semi‐Arid Brazil Using AquaCrop

open access: yesIrrigation and Drainage, Volume 75, Issue 1, Page 411-424, February 2026.
ABSTRACT Forage production in semi‐arid regions of Brazil is limited by water deficit. This study aimed to identify the most adapted and efficient production systems and define their agricultural calendars for the semi‐arid region of Brazil. Twenty‐nine production arrangements that included different cropping conditions, plant density, plant cycles ...

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

open access: yesLa 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.

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

open access: yesIrrigation 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″)
