Irrigation water economic value and productivity: An econometric estimation for maize grain production in Italy Agric. Water Manag. (IF 6.7) Pub Date : 2024-03-08 Rebecca Buttinelli, Raffaele Cortignani, Francesco Caracciolo
Climate change, characterized by rising temperatures and limited precipitation, has intensified the demand for irrigation water while simultaneously restricting its availability. This challenge poses significant risks to agricultural and food production, particularly in the Mediterranean regions where, recently, water deficits have led to substantial production losses and quality issues. Water is a

Sap flow characteristics and water demand prediction of cash crop in hyper-arid areas Agric. Water Manag. (IF 6.7) Pub Date : 2024-03-07 Yunfei Liu, Dongwei Gui, Xiaoping Chen, Qi Liu, Fanjiang Zeng
Crop sap flow is a critical indicator of crop water demand, and predicting its variation trend is essential for adjusting agricultural planting structure and managing water resource in hyper-arid areas. Presently, research on crop sap flow in hyper-arid areas faces limitations due to inadequate meteorological data and restricted monitoring duration, leading to imprecise assessments of environmental

Water productivity and yield characteristics of transplanted rice in puddled soil under drip tape irrigation Agric. Water Manag. (IF 6.7) Pub Date : 2024-03-06 Ramtin Nabipour, Mohammad Reza Yazdani, Farhad Mirzaei, Hamed Ebrahimian, Fatemeh Alipour Mobaraki
Lowland rice flooding, while consuming considerable water, has adverse environmental effects, including releasing methane into the atmosphere, aggravating climate change. Several drawbacks can be attributed to water-saving alternatives, such as aerobic rice, whereas rice drip irrigation techniques have been evaluated primarily under aerobic conditions. This study investigated drip tape irrigation technique

Cover crops and irrigation impacts on corn production and economic returns Agric. Water Manag. (IF 6.7) Pub Date : 2024-03-05 Dillon Russell, Gurbir Singh, Nicolas Quintana-Ashwell, Gurpreet Kaur, Drew Gholson, L. Jason Krutz, Kelly A. Nelson
Increases in irrigated crop acreage and frequent droughts during the growing season have caused continual groundwater decline of the Mississippi River Valley Alluvial Aquifer in the Mississippi Delta region. A field experiment was conducted from 2019 to 2021 to determine if combinations of irrigation scheduling thresholds and cover crops (CCs) could improve corn ( L.) production, water productivity
