Corn Water Use And Yield For Various Limited Irrigation Treatments, Simon Van Donk, Don Davison, Jim Peterson
Corn Water Use And Yield For Various Limited Irrigation Treatments, Simon Van Donk, Don Davison, Jim Peterson
West Central Research and Extension Center, North Platte
With limited water resources, it becomes more critical to know how much and when to irrigate. The objective of this study was to determine the effect of the amount and timing of irrigation on corn (Zea mays L.) yield using subsurface drip irrigation (SDI). A field study was conducted at North Platte, Nebraska in 2007 - 2009, using two SDI systems. The study was replicated eight times on the older SDI system (SDI1) and four times on the newer SDI system (SDI2). On SDI1, there were nine treatments to impose different irrigation regimes, ranging from dryland to fully …
Effect Of Crop Residue On Soil Water Content And Yield Of Deficit-Irrigated Corn And Soybean, Simon Van Donk, Steven R. Melvin, Jim Peterson, Don Davison
Effect Of Crop Residue On Soil Water Content And Yield Of Deficit-Irrigated Corn And Soybean, Simon Van Donk, Steven R. Melvin, Jim Peterson, Don Davison
West Central Research and Extension Center, North Platte
It is believed that reduced tillage, with more crop residue on the soil surface, conserves water, especially in arid and semi-arid climates. However, the magnitude of water conservation is not clear. In 2007, a study was initiated on the effect of residue on soil water content and crop yield at North Platte, Nebraska. The experiment was conducted on plots planted to field corn (Zea mays L.) in 2007 and 2008, and soybean (Glycine max) in 2009. There were two treatments: residue-covered soil and bare soil. Bare-soil plots were created in April 2007 by using a dethatcher …
Crop Residue Cover Effects On Evaporation, Soil Water Content, And Yield Of Deficit‐Irrigated Corn In West‐Central Nebraska, Simon Van Donk, Derrel L. Martin, Suat Irmak, Steven R. Melvin, Jim Peterson, Don Davison
Crop Residue Cover Effects On Evaporation, Soil Water Content, And Yield Of Deficit‐Irrigated Corn In West‐Central Nebraska, Simon Van Donk, Derrel L. Martin, Suat Irmak, Steven R. Melvin, Jim Peterson, Don Davison
West Central Research and Extension Center, North Platte
Competition for water is becoming more intense in many parts of the U.S., including west‐central Nebraska. It is believed that reduced tillage, with more crop residue on the soil surface, conserves water, but the magnitude of water conservation is not clear. A study was initiated on the effect of residue on soil water content and corn yield at North Platte, Nebraska. The experiment was conducted in 2007 and 2008 on plots planted to field corn (Zea mays L.). In 2005 and 2006, soybean was grown on these plots. There were two treatments: residue‐covered soil and bare soil. Bare‐soil plots …

Effect Of Amount And Timing Of Subsurface Drip Irrigation On Corn Production, Simon Van Donk, James Petersen, Don Davison
Effect Of Amount And Timing Of Subsurface Drip Irrigation On Corn Production, Simon Van Donk, James Petersen, Don Davison
West Central Research and Extension Center, North Platte
Subsurface drip irrigation (SDI) has the potential of being a more efficient irrigation system compared to systems such as center pivot and furrow irrigation. The objective of this study was to determine the effect of the amount and timing of irrigation, using SDI, on corn (Zea mays) production. A field study was conducted at North Platte, Nebraska in 2007 and 2008, using two SDI systems. The study was replicated eight times on the older SDI system (SDI1) and four times on the newer SDI system (SDI2). On SDI1, there were nine treatments to impose different irrigation regimes, ranging from dryland …
Effect Of Crop Residue On Soil Water Content And Yield Of Sprinkler-Irrigated Corn, Simon Van Donk, Derrel Martin, Suat Irmak, Steven Melvin, James Petersen
Effect Of Crop Residue On Soil Water Content And Yield Of Sprinkler-Irrigated Corn, Simon Van Donk, Derrel Martin, Suat Irmak, Steven Melvin, James Petersen
West Central Research and Extension Center, North Platte
Competition for water is becoming more intense in many parts of the USA, including west-central Nebraska. It is believed that reduced tillage with increased crop residue conserves water, but the magnitude of water savings is not clear. In 2007, a study was initiated on the effect of residue on soil water content and crop yield at North Platte, Nebraska. The experiment was conducted on a set of plots planted to field corn (Zea mays). There were two treatments: residue-covered soil and bare soil. Bare-soil plots were created by using a dethatcher and subsequent hand-raking, removing most of the …
