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 Jan 2010

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 Jan 2010

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 …


The Effect Of Different Nitrogen And Irrigation Levels On Grain Β-Glucan Content In Some Durum Wheat Cultivars, Mustafa Güler Jan 2010

The Effect Of Different Nitrogen And Irrigation Levels On Grain Β-Glucan Content In Some Durum Wheat Cultivars, Mustafa Güler

Turkish Journal of Agriculture and Forestry

\beta-glucan is a non-starchy, water-soluble polysaccharide component of wheat grain that positively affects grain nutrient quality. High \beta-glucan content in wheat grain also has a cholesterol-lowering effect in humans. The aim of this study was to evaluate the effect of nitrogen and irrigation on durum wheat grain \beta-glucan content. Correlations between durum wheat grain \beta-glucan content, and grain yield and some quality characteristics were examined. Kunduru 1149, Kızıltan 91, and Çakmak 79 durum wheat cultivars were used as material, and 0-, 75-, and 150-mm irrigation levels with 0, 40, 80, and 120 kg ha^{-1} nitrogen rates were applied. Higher nitrogen …
