Maize Yield, Water Productivity and Economic Analysis Under Different Irrigation and Nitrogen Management Strategies Using Field Data and CERES‐Maize Model

Irrigation and Drainage, EarlyView.
ABSTRACT There is limited integrated evaluation of nitrogen (N) and irrigation management strategies for improving maize yield and productivity using crop models. The effects of N and irrigation on maize yield and productivity under centre pivot (CPI) and subsurface drip irrigation (SDI) using the CERES‐Maize model were investigated. N treatments were (

Drainage Water Reuse Through a Baffled Constructed Wetland System: A Pilot Study in the Harran Plain, Türkiye

Irrigation and Drainage, EarlyView.
ABSTRACT The reuse of agricultural drainage water requires low‐cost pretreatment for sediments and salts. This study developed a pilot‐scale horizontal surface‐flow baffled constructed wetland for passive pretreatment of agricultural drainage water.

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.

Improved thermal resummation for multi-field potentials

Journal of High Energy Physics
The resummation of large thermal corrections to the effective potential is mandatory for the accurate prediction of phase transitions. We discuss the accuracy of different prescriptions to perform this resummation at the one- and two-loop level and point

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 ...

Resummation for Nonequilibrium Perturbation Theory and Application to Open Quantum Lattices

Physical Review X, 2016
Lattice models of fermions, bosons, and spins have long served to elucidate the essential physics of quantum phase transitions in a variety of systems. Generalizing such models to incorporate driving and dissipation has opened new vistas to investigate ...

A new resummation scheme in scalar field theories

, 2013
A new resummation scheme in scalar field theories is proposed by combining parquet resummation techniques and flow equations, which is characterized by a hierarchy structure of the Bethe–Salpeter (BS) equations.

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 ...

Tadpole resummations in string theory

Physics Letters B, 2008
While R-R tadpoles should be canceled for consistency, string models with broken supersymmetry generally have uncanceled NS-NS tadpoles. Their presence signals that the background does not solve the field equations, so that these models are in "wrong" vacua.
