Over the past 15-20 years, agricultural production in Ukraine has been reoriented to cultivation of more profitable, highly liquid, as well drought-resistant crops, particular – chickpeas and sunflowers. Simultaneously, technology growing these crops is quite energy-consuming, especially under irrigation conditions. Therefore, research on impact micro-irrigation system designs energy parameters...

Highlights Subsurface drip irrigation (SDI) has continued to expand in area within the U.S. during last 15 years. Research with SDI continues for multiple crop types (fiber, grain and oilseed, horticultural, forage, turf). usage on many crops matured through research development of appropriate strategies technologies Despite some persistent challenges successful use SDI, important opportunities...

Agricultural nitrogen (N) use is a major contributor to environmental problems arising from nitrous oxide emissions and N loading groundwater. Advances in the adoption of conservation practices requires better understanding agronomic context for cropping systems. This paper tests hypotheses about how knowledge barriers influence management orchard agroecosystems. Agronomic are characterized by ...

In the southeastern U.S. Coastal Plains, supplemental irrigation is required to reduce the impact of short‐term droughts and yield‐reducing plant water stress that can occur at least biennially. Sprinkler irrigation is commonly used to water agronomic crops in the region. Microirrigation is typically used for high value fruit and vegetable crops. In recent years and at some locations, microirri...
