Overview

What is he best known for?

The fields of study he is best known for:

  • Agriculture
  • Ecology
  • Irrigation

Suat Irmak mainly investigates Evapotranspiration, Irrigation, Agronomy, Hydrology and Deficit irrigation. Suat Irmak has researched Evapotranspiration in several fields, including Wind speed, Vapour Pressure Deficit, Transpiration, Atmospheric sciences and Vegetation. His Irrigation research is multidisciplinary, incorporating elements of Soil water, Crop yield and Growing season.

His research investigates the link between Agronomy and topics such as Semi-arid climate that cross with problems in Field capacity and Field experiment. He usually deals with Hydrology and limits it to topics linked to Relative humidity and Monthly average and Evaporation. His biological study deals with issues like Water-use efficiency, which deal with fields such as Drip irrigation, DNS root zone and Arid.

His most cited work include:

  • Yield response of corn to deficit irrigation in a semiarid climate (219 citations)
  • Determination of Crop Water Stress Index for Irrigation Timing and Yield Estimation of Corn (192 citations)
  • Effect of irrigation amounts applied with subsurface drip irrigation on corn evapotranspiration, yield, water use efficiency, and dry matter production in a semiarid climate (182 citations)

What are the main themes of his work throughout his whole career to date?

Suat Irmak mostly deals with Evapotranspiration, Agronomy, Irrigation, Hydrology and Soil water. Suat Irmak interconnects Atmospheric sciences and Vegetation in the investigation of issues within Evapotranspiration. He regularly ties together related areas like Crop residue in his Agronomy studies.

His Irrigation study integrates concerns from other disciplines, such as Water use and Growing season. As part of one scientific family, Suat Irmak deals mainly with the area of Hydrology, narrowing it down to issues related to the Energy balance, and often Sensible heat. He focuses mostly in the field of Penman–Monteith equation, narrowing it down to matters related to Wind speed and, in some cases, Relative humidity and Vapour Pressure Deficit.

He most often published in these fields:

  • Evapotranspiration (54.10%)
  • Agronomy (36.48%)
  • Irrigation (35.66%)

What were the highlights of his more recent work (between 2018-2021)?

  • Agronomy (36.48%)
  • Irrigation (35.66%)
  • Evapotranspiration (54.10%)

In recent papers he was focusing on the following fields of study:

Suat Irmak focuses on Agronomy, Irrigation, Evapotranspiration, Soil water and Crop. In his work, Crop evapotranspiration, Grain yield and Subtropics is strongly intertwined with Water balance, which is a subfield of Agronomy. Suat Irmak combines subjects such as Fertilizer and Growing season with his study of Irrigation.

His research in Evapotranspiration intersects with topics in Soil type, Water use, Canopy, Atmospheric sciences and Precipitation. Suat Irmak works mostly in the field of Soil water, limiting it down to topics relating to Water content and, in certain cases, Soil science and Agricultural engineering. His Crop yield study combines topics in areas such as Deficit irrigation and Water-use efficiency.

Between 2018 and 2021, his most popular works were:

  • Di-Sense: In situ real-time permittivity estimation and soil moisture sensing using wireless underground communications (47 citations)
  • A Theoretical Model of Underground Dipole Antennas for Communications in Internet of Underground Things (29 citations)
  • NU-Spidercam: A large-scale, cable-driven, integrated sensing and robotic system for advanced phenotyping, remote sensing, and agronomic research (20 citations)

In his most recent research, the most cited papers focused on:

  • Agriculture
  • Ecology
  • Irrigation

His scientific interests lie mostly in Agronomy, Soil water, Evapotranspiration, Canopy and Water content. Suat Irmak mostly deals with Sorghum in his studies of Agronomy. The various areas that he examines in his Soil water study include Agriculture and Agricultural productivity.

His study in Evapotranspiration is interdisciplinary in nature, drawing from both Water use, Yield, Irrigation and Sowing. In his study, Allometry, Leaf area index, Precipitation and Biomass is strongly linked to Growing season, which falls under the umbrella field of Canopy. His research integrates issues of Soil science, Loam, Relative permittivity and Calibration in his study of Water content.
