1	Application of Fibrolytic Enzymes and Bacterial Inoculants to Sorghum Silage and Small-Grain Hay Thomas, Martha 1980- 02 October 2013 (has links) Fibrolytic enzymes and microbial inoculants have potential to improve the value of feedstuff and feedstock. An experiment was conducted to determine the nutritive value, ensiling characteristics, and in situ disappearance kinetics of sorghum (Sorghum bicolor L.) silages pretreated with fibrolytic enzyme (xylanase plus cellulase: XC) or microbial [Promote ASB (Lactobacillus buchneri and L. plantarum); PRO] inoculants. The greatest yield was for cultivar PS 747 and the least for MMR 381/73 (MMR). Neutral detergent fiber (NDF) concentration was least for XC treated silage, and acid detergent fiber (ADF) concentration was least for XC and PRO treated silage. In vitro true digestibility (IVTD) was greatest for PRO treated Dairy Master BMR (DBMR), whereas, acid detergent lignin was least for PRO treated DBMR. Aerobic stability was not improved by PRO, however, aerobic stability of XC treated MMR was 63 h greater than the control. Generally, the in situ disappearance kinetics were improved with the application of XC and PRO, and XC had the greatest effect on silage with greater NDF and ADF concentrations. A second experiment was conducted to determine if the same application rates of either inoculant would reduce the fiber fraction of two cultivars each of wheat (Triticum aestivum L.) or oat (Avena sativa L.) hays. Forage was harvested twice during the tillering stage (H1) and (H2) and a third after grain harvest (H3). The IVTD was greater for oat than wheat due to a lesser fiber fraction. Forage from H2 had lesser NDF and ADF and greater CP and IVTD concentrations. In situ DM, NDF, ADF, and ERD were greater for wheat and oat at tillering than stover and NDF and ERD were greater for Harrison than Fannin at tillering. Treatment of oat or wheat hays with XC or PRO enhanced in situ disappearance kinetics. Both XC and PRO may be used to reduce the fiber fractions of sorghum silage and small-grain hay. Additionally, it appears the inoculant PRO can be used to improve fermentation characteristics of sorghum silage. small-grain hay Silage Sorghum

5	Varieties and Quality of Small Grain Seed Planted in Utah in 1958 Jensen, Louis A. 01 May 1960 (has links) High quality seed is of first importance in efficient crop production. Seed is one of the major factors affecting yield and quality of the crop. High quality seed is of adapted varieties, has high gemination, and is free of foreign material and weed seeds. Crop seed containing weed seeds may be the means of infesting farm land with weeds. Such seed is expensive at any price. Varieties Quality Small Grain Seed Utah Agronomy and Crop Sciences

8	Service model for libraries in an agricultural environment with specific reference to the library of the ARC-Small Grain Institute Kilian, Juliette January 2013 (has links) This dissertation reports on a study that investigated the functions and services that are rendered at the library of ARC-Small Grain Institute in Bethlehem. The study was directed by the research questions that included the investigation in library services and sources globally; the information seeking behaviour of the patrons of the library as well as the skills and competencies needed by librarians to render an effective service in a constant changing environment. These components served as a foundation for the development of a proposed service model, which reflects the incorporation of the changing roles of librarians in a research library. The current services and sources of the ARC-SGI library were discussed and compared to other libraries. A systematic review of the literature included the information seeking behaviour and information needs of researchers as well as the skills and competencies of librarians. A mixed-method approach, using both qualitative and quantitative methods, has been applied in the study. Data was collected through questionnaires and fifteen semi-structured interviews were held with selected patrons of ARC-SGI. The findings showed that information needs depends mostly on the different stages of research and flows directly from the type of work that they do. Attention was given to preferred source choices and problems experienced during information seeking. Training needs were addressed as well as the needs for additional information needed from the library. Based on the results, the study proposed a service model for an agricultural library. The model displays the library within the setting of an organisation as it supports the mission and vision of the parent organisation. It illustrates all the interdependent components that are essential for a successful agricultural library. The model also outlines the strategies of on-going evaluation and monitoring of the library services; the information needs and information seeking behaviour of the patrons as well as the challenges facing the library. The study concluded by making certain recommendations that can benefit the library of ARC-SGI, which will be an improvement added to the current services. A few suggestions are made for future research, which have definite advantages for an agricultural library within an organisation. / Dissertation (MIS)--University of Pretoria, 2013. / Information Science / unrestricted Information seeking behaviour Agricultural researchers ARC-Small Grain Institute Information needs Skills and competencies UCTD C14/4/58/gm
