Pure Live Seed
This publication explains how to evaluate seed by considering the purity and germination percentages of the seed and calculating the actual cost of the good useable seed in the bag
Wheat Sedimentation Testing in South Dakota
Sedimentation studies of hard red spring and hard red winter wheat produced in South Dakota were begun at South Dakota State College in 1962. A grant from the South Dakota Wheat Commission facilitated the purchase of necessary equipment for a sedimentation testing laboratory supervised by the Agronomy Seed Laboratory. The sedimentation test is a composite evaluation of both the quantity and quality of protein in bread wheat. It is not a complete measure of baking quality, but it is an easily performed test which indicates, in a general way, the market quality (bread making quality) of a sample of wheat. High sedimentation test readings indicate wheat high in protein content and in protein quality. Such wheat yields flour that has a high bread loaf volume and commands a premium on the market. Low sedimentation readings indicate wheat that is low in protein content and/or quality. Wheat samples were collected in South Dakota from many sources such as: county crop shows, county demonstration plots, experiment stations and substations, and certified seed producers. Tables 1 and 2 summarize the results of tests on wheat samples growing in 1961 and 1962. (See more in Text
Drill Box Survey of Spring Planted Grains in South Dakota
Many times the questions has been asked – What kind and quality of seeds are South Dakota farmers planting? In an effort to at least partially answer the questions, a drill box survey was conducted in the early spring of 1964. The survey was a combined effort of individuals from the Seed Certification Service of the South Dakota Crop Improvement Association, State Department of Agriculture, Cooperative Extension Service, and Agronomy Department of S. D. State University
South Dakota Seed Quality: A Drillbox Survey
In a 1969 survey, a total of 450 samples of oats, barley, hard red spring wheat, durum wheat, and flax were taken during the spring planting season. These samples were collected in 23 eastern South Dakota counties. Several questions were asked the operator about each seed lot at the time the sample was collected. The samples were analyzed at the Seed Testing Laboratory at South Dakota State University for percent of pure seed, kind and number per pound of all crop seed, common weed seeds, noxious weed seeds, and germination. A copy of the analysis was sent to the cooperator
Physical Quality of South Dakota Wheat
The producer selling wheat to the country elevator or shipper does so on the basis of physical quality of the grain. Increased wheat production throughout the world has stiffened competition in the wheat market and all wheat producers are realizing the need for keeping a closer watch on quality. A study of the physical quality of hard red winter and hard red spring wheat in South Dakota began in 1963. Each summer for 5 years, samples were taken from trucks at country elevators to ascertain the quality of wheat being delivered by South Dakota producers. The samples were studied and graded according to the Official Grain Grading Standards of the United States Department of Agriculture
Wheat Quality and Yield. . . Spring versus Winter
Recent introduction of more winter hardy varieties of winter wheat coupled with new ideas in cultural practices have greatly improved the potential of winter wheat in South Dakota. Basic to the decision of whether to grow spring or winter wheat are questions of quality, protein and yield. An analysis of the quality of the 1967 South Dakota wheat crop was made from samples taken in 11 counties where both winter and spring wheat were produced. The counties were: Butte, Faulk, Haakon, Hand, Hughes, Hyde, Perkins, Potter, Spink, Stanley and Sully
Factors Influencing Pediatric Dental Program Directorsâ Selection of Residents and Demographics of Current Directors
The primary goal of this study was to examine the criteria that influence rankings of candidates by advanced education program directors in pediatric dentistry. Secondary objectives were to obtain information on the resident selection process and to explore demographics of current program directors. A survey was sent in 2005 to all sixtyâ three program directors of pediatric dentistry residency programs accredited within the United States for the graduating class of 2007. The survey had a response rate of almost 78 percent (49/63). Respondents were requested to rank the importance of eleven factors that are typically included in the selection criteria for pediatric dentistry residents. Factors were rated on a scale of critical, very important, fairly important, somewhat important, and not important. The four highest ranked criteria by program directors were the following, in order: National Board scores, dental school clinical grades, class rank, and grade point average (GPA). Other factors ranked in descending order of perceived importance were the following: dental school basic science grades, experience in pediatric dentistry, extracurricular activities, completion of a general practice residency or advanced education in general dentistry program, the application essay, a publication or professional presentation, and private practice experience. All directors ranked personal interviews as very important to critical. Letters of recommendation from a pediatric dentistry department chairperson or faculty member were viewed more favorably than letters from dental school deans and nonâ pediatric dentistry faculty. Fiftyâ seven percent of the directors responding (28/49) were male, and 81 percent (40/49) were white, nonâ Hispanic. Fiftyâ nine percent of the directors (29/49) graduated from a residency program over twenty years ago, with 39 percent (19/49) having been a director for less than five years.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/153594/1/jddj002203372009733tb04706x.pd
