Nonlinearities of Penman and Penman-Monteith Equations across Multiple Timescales

, 2023
The nonlinear Penman and Penman-Monteith equations, widely used for estimating surface evapotranspiration at regional and global scales, were derived from turbulent transport of heat fluxes and thus apply to subhourly scale. However, these equations have been directly applied with hydrometeorological variables averaged at longer time intervals, leading

Alleles From Crop Wild Relatives Accumulated by Long‐Term Adaptation to Low‐Input Environments Contribute to Yield Advantages in Wheat (Triticum aestivum)

Plant Breeding, EarlyView.
ABSTRACT Increasingly variable climate conditions are affecting crop production, leading to greater yield fluctuations, which in turn are impacting global food security. Introducing alleles from regions where the expected stress conditions occur, so‐called exotic alleles, could serve as a means to mitigate these effects. We examined the value of exotic

Physical land suitability assessment for sugarcane (Saccharum officinarum L.) production in Western Ethiopia

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Land is a non‐renewable resource that has a finite quantity, and efficient use of this resource is imperative for food security, development, and adaptation to climatic change. In this regard, land suitability analysis is a fundamental decision‐support system that ensures the allocation of this resource for an optimal production agenda while ...

Quality Assessment and Predictive Modeling of Chickpea, Lentil and Camelina Yield: Effects of Nitrogen, Irrigation, Rainfed Conditions, and Intercropping Using Machine Learning Approaches

Legume Science, Volume 8, Issue 2, June 2026.
ABSTRACT Given increasing water scarcity, the need to reduce chemical inputs, and the growing demand for nutritionally valuable vegetable oils, identifying sustainable cropping systems for camelina production has become increasingly important. This study aimed to evaluate the combined effects of nitrogen application, irrigation regimes (irrigated and ...
