Forty Years Of Dairy Cattle Breeding At The North Platte Experiment Station, Mogens Plum, Myron G.A. Rumery
Forty Years Of Dairy Cattle Breeding At The North Platte Experiment Station, Mogens Plum, Myron G.A. Rumery
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
In 1913 the Nebraska Legislature appropriated $17,500 to establish a Dairy Department at the North Platte Experiment Station. The department's herd was to be used in demonstrating management and breeding practices and as a source of breeding stock. Since the North Platte herd was started, research in the field of animal breeding has developed new concepts in many phases of dairy cattle breeding and selection. The purpose of the present study is to analyze the progress made under a system of dairy cattle breeding and selection carried out according to the principles that dominated 40 years ago. The results of …
Rate Of Potato Tuber Growth On Dryland At The Box Butte Experiment Farm, H. O. Werner
Rate Of Potato Tuber Growth On Dryland At The Box Butte Experiment Farm, H. O. Werner
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Relatively late planting of potatoes, i.e., between June 12 and 25, has become the prevailing practice in the dryland areas of western Nebraska. Late planting distinctly improves the color and type of tubers, and reduces losses due to insects and diseases (especially soil-borne diseases caused by Fusarium and Streptomyces). Growers must decide each year whether the increase in yield and tuber maturity gained by delaying harvest will be offset by the risk of impaired tuber quality due to scab or possible serious field frost damage. Information about the rate at which tubers are developing by various dates is essential …
Comparative Measurements Of Holstein, Ayrshire, Guernsey, And Jersey Females From Birth To Seven Years, H. P. Davis, I. L. Hathaway
Comparative Measurements Of Holstein, Ayrshire, Guernsey, And Jersey Females From Birth To Seven Years, H. P. Davis, I. L. Hathaway
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Body measurements are important for a proper understanding of how growth takes place in animals. Unfortunately, few growth data other than for weight have been published concerning dairy cattle. This is a report of measurements of females in the University of Nebraska dairy herd made as part of a long-time growth study. During the period 1922 to 1942 each animal born into the herd was weighed and measured at regular intervals. Presented here are the data for weight, height, length, width, depth, girth and hide thickness for females of the Holstein, Ayrshire, Guernsey, and Jersey breeds. The average body measurements …
False Smut Of Buffalograss, John L. Weihing
False Smut Of Buffalograss, John L. Weihing
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
False smut of buffalograss, Buchloe dactyloides (Nutt.) Engelm., caused by Cercospora seminalis Ell. & Ev. is a disease that destroys the unfertilized ovary. The disease was first reported by J. B. Ellis and B. M. Everhart in 1888. They gave only a brief description of the disease and named the causal fungus Cercospora seminalis. There are no etiological studies of false smut recorded in the literature. The origin of the term "false smut" is unknown to the author, but it so descriptively fits the general appearances of the disease that one readily understands its usage. The following studies were …
Streak Mosaic Of Wheat In Nebraska And Its Control, R. Staples, W. B. Allington
Streak Mosaic Of Wheat In Nebraska And Its Control, R. Staples, W. B. Allington
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
This bulletin reports the results of studies on the epidemiology of wheat streak mosaic under Nebraska conditions. Particular attention is given to the occurrence and certain characteristics of the mite vector of the virus, the relation of weather and other factors to some of its activities, a correlation of certain mite situations with epidemics of the disease, and recommendations for disease control.
