EC92-124 Nebraska Handbook of Range Management

Every Nebraskans should be interested in rangeland. The plants, soil, and water are the foundation of Nebraska\u27s economy and quality of life. Rangeland is one of Nebraska\u27s most important and valuable natural resources because it: • produces forage for livestock and wild game; • provides a varied habitat for many wildlife species; • protects the soil from wind and water erosion; • preserves a germplasm bank for many plant species that may become important for yet unknown uses; • purifies and enhances the environment by cleasing the air, filtering the runoff to streams, increasing the intake of precipitation, and aiding groundwater recharge; • perseveres in adversity and renews itself when the opportunity is provided by those who use and sometimes abuse it; and • pleases those who have learned to appreciate the beauty and aesthetic qualities of rangeland. These are called the Seven P\u27s of Rangeland. Range plants must be the right kind and kept productive for best use of this resource. Most people enjoy wildlife, hunting, camping, clean water, fishing, and eating beef. Range supplies us with those items, so we must management it wisely

EC00-153 Selecting Alfalfa Varieties for Nebraska

Yield potential, pest resistance and seed price should be considered when selecting alfalfa varieties in Nebraska. The most important variety decision on many farms and ranches is the selection of alfalfa. The choice of alfalfa variety affects production for three to 10 or more years, whereas varieties of annual crops can be change every year. This extension circular lists the alfalfa varieties that have been tested in Nebraska with commercial seed for two or more years since 1997 and marketed in the state. These are the 2000 results

Genotype and Genotype x Environment Interaction Effects on Forage Yield and Quality of Intermediate Wheatgrass in Swards

Genetic differences among cultivars or strains for specific traits can be significantly reduced or increased by differential genotypic responses to environments. The objective of this study was to determine the relative magnitude of genotype and genotype x environment interaction effects, which are due to differential responses, on forage yield and quality of intermediate wheatgrass [Thinopyrum intermedium (Host) Barkworth & D.R. Dewey] when grown in seeded swards in the central Great Plains. Thirty-four strains (genotypes), which included cultivars, experimental strains, and PI lines, were grown in replicated trials at Mead, North Platte, and Alliance, NE. The three sites differed markedly in precipitation and length of growing season. There were significant differences among strains for all evaluated traits. Genotype x location and genotype x year interaction effects were not significant for in vitro dry matter digestibility (IVDMD), indicating that this trait is quite stable across environments. Genotype x location interaction effects were significant for forage yield and protein concentration; genotype x year effects were significant for forage yield. Spearman rank correlations, used to test for consistency of ranking of the strains across environments, were high and significant for IVDMD, but were low and usually not significant for forage yield. Improving IVDMD should be emphasized in intermediate wheatgrass breeding programs, since there is substantial genetic variation for IVDMD, it is stable across environments, and it can improve livestock production per hectare

G77-357 Selecting Alfalfa Varieties for Nebraska (Revised December 1994)

The most important variety decision made on many farms and ranches is the selection of alfalfa varieties. The choice of alfalfa variety affects production for three to 10 or more years. Yield potential, pest resistance and seed price all should be considered in selecting alfalfa varieties in Nebraska. This NebGuide discusses them

Effect of Summer Grazing on Crude Protein and Digestibility of Winter Diets of Cattle in the Nebraska Sandhills

Twenty-one pastures (three pastures/ treatment) were used in a two-year study to determine the effects of summer grazing on winter diet quality of Sandhills range. Summer grazing treatments consisted of no summer grazing (control) and June or July grazing at three stocking rates. After summer grazing, pastures were then diet sampled using esophageally fistulated cows in November, January and March following summer treatments. Year and sampling date had a significant effect on CP and IVDMD of winter range diets, whereas summer grazing treatments did not have a large impact
