Pb897 Commercial Bush Snapbean Production, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

Snapbean production in Tennessee ranges from 6,000 to 9,000 acres and contributes $7 to $9 million annually to the state’s economy. The major production area is located within a 50-mile radius of Crossville, with some early production in the south central portion of the state. Small acreages are grown throughout the state for local sales.

Presently, the acreage is about 45 percent processing and 55 percent fresh market. Fresh market packing operations have increased about five-fold in the last few years.

The varying elevations and temperatures enable producers to plant early at lower elevations and make summer plantings at higher …

Pb1544 Comparing The Cost Of Broadcasting Versus Injecting Nitrogen In No-Tillage Corn, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

No-tillage has become a popular production option with many Tennessee farmers in the past 20 years. In 1993, no-tillage production systems were used on 290,000 acres of corn in Tennessee, or 44 percent of the total corn acreage planted in the state (TDA). Many farmers see no-tillage as a way to reduce the cost of growing corn. Others have chosen no-tillage as a way to comply with governmental regulations covering the farming of highly-erodible soils.

Input levels and prices are important to consider in any production system. A major expense in corn production is nitrogen (N) fertilizer. No-tillage budgets published …

Arkansas Rice Research Studies 1994, B. R. Wells

Arkansas Agricultural Experiment Station Research Series

The research reports in this publication represent one year of results; therefore, these results should not be used as a basis for longterm recommendations. Several research reports in this publication dealing with soil fertility also appear in Arkansas Soil Fertility Studies 1994, Arkansas Agricultural Experiment Station Research Series 443. This duplication is the result of the overlap in research coverage between the two series and our effort to inform Arkansas rice producers of all the research being conducted with funds from the rice check-off.

Demography, Reproduction, Diet And Crop Depredation In Three Species Of Rodents In Natural And Irrigated Fields In Nigeria, Safianu Rabiu

Biological Sciences Theses & Dissertations

Rodent populations of Arvicanthis, Mastomys and Tatera were studied during July 1990 to August 1992 in both natural and irrigated savannah fields of northern Nigeria. Tatera was entirely absent from the irrigated fields. Irrigation enhanced higher rodent population densities in the magnitude of three to four times over densities in the natural field. Arvicanthis was the most abundant of the three species in both sites. Tatera was the least common in the natural site. Adult survival rates in Arvicanthis and Tatera were significantly higher than Mastomys. Survival rates of both adult and young differed between the wet and dry …

Clonal-By-Environment Interactions Influence Isoflavonoid Accumulation In Cicer Milkvetch, Andrew W. Lenssen, C. E. Townsend, S. S. Martin

Andrew W. Lenssen

Cicer milkvetch (Astragalus cicer L.) is a perennial, nonbloatinducing forage legume adapted to temperate environments. For unknown reasons, however, ruminants grazing cicer milkvetch in pure stands have become photosensitized, or sunburned, in some environments, Isoflavonoids are involved with diverse biological activities, including estrogenism, disease resistance, and, potentially, photosensitization. We conducted a series of studies from 1991 to 1993 to identify factors that influence the accumulation of isoflavonoids. In separate greenhouse studies, elicited leaflets from the parental clones of ‘Monarch’ and. ‘Windsor’ cicer milkvetch were analyzed for isoflavonoid accumulation. Growth chamber studies were conducted to investigate the clonal variability of leaflet …

An Economic Study Of The Relative Profitability Of Alfalfa Production And Marketing Practices, David Claycomb

Masters Theses & Specialist Projects

The seasonality of the price of alfalfa hay in Kentucky was studied as well as the potential cost or profitability of storage of this hay. Economic comparison of alfalfa hay production to other farm enterprises was carried out. In addition, an estimate of the value of two qualities of alfalfa hay was calculated based on 1991 prices. The analysis of 41 years of marketing data demonstrated significant differences (P<.01) in price with seasonal lows in June/July and a steady increase in price to a high in March. In general (based on $100 per ton hay and 12% interest) the alfalfa hay producer could lose from $5 to $10 storing hay and selling at a later date. There were some specific conditions where he might have realized a return to storage of $0.16 to $1.48 per ton. A further evaluation of average (KY Feeder) and good (KY Pride) quality hays indicated that current prices of $70-$75 and $100 per ton respectively were the prices where a dairyman would be able to include this hay in the cow's total diet. Even with problems of quality and quantity of alfalfa hay, the economic returns to the production of alfalfa hay were favorable when compared to other crops in Kentucky with the additional benefit of alfalfa being a crop that can result in reduced soil erosion from sloping land. Returns above variable costs can be from $120 to $400 per acre depending upon yield and sale price. However, an understanding of seasonality of price as well as storage costs need to be considered by alfalfa hay producers to assure realizing the above returns.

A Computer-Based Tool For Introducing Turfgrass Species, T. W. Fermanian, David J. Wehner

Office of the Dean (CAFES) Scholarship

An essential component of an introductory turfgrass management course is the description of how turfgrass species are adapted to different cultural systems and environments. The objectives of this project were to develop an interactive program to introduce the characteristics of turfgrass species and their optimum environments and to evaluate the students' gain in understanding turf species characteristics through this approach. A self-contained application, Turf Species, was constructed using the SuperCard development tool. Turf Species consists of three sections including a self-paced tour of the species, a what if establishment section, and randomly composed reinforcement quizzes with automatic grading. Turf Species …

Canola : Golden Oil For Farmers And Consumers, Paul Carmody

Journal of the Department of Agriculture, Western Australia, Series 4

It is feasible that canola could become Western Australia's fourth largest crop after wheat, barley and lupins by the turn of the century.

Without the stigma attached to its parent crop, rapeseed, canola has also become one of the most successful international agricultural product launches, proving itself not only a useful cropping alternative but a healthy oil for consumers. State Oilseeds Adviser PAUL CARMODY sets the scene.

Planting Seeds For A Sound Future, Peter Portmann

Journal of the Department of Agriculture, Western Australia, Series 4

Royalties have been collected sales of all new crop varieties released in We tern ustralia by the Department of Agriculture since the lease of Merrit lupins and Yilgarn oats in 1991.

Many questions have been raised by farmers about these royalties. Why pay royalties when we have already paid for the development of the varieties through our Grains Research end: Development Corporation levy? Why should we pay a Jevy if it - is just going back into Government revenue? Is there any real benefit to us?

USAID conducted an overall evaluation of the Collaborative Research Support Programs (CRSPs), including lNTSORMIL, between May and July 1994. According to the "CRSP Evaluation Scope of Work" developed by USAID, the goal of this evaluation was to provide an objective assessment of the degree to which each of the CRSPs has had an impact on increasing agricultural production and development, and improving natural resource management through the development and dissemination of new and/or more appropriate sustainable agriculture technologies. The evaluation also assessed the extent to which the CRSP framework has responded to past Agency expectations and objectives and if the …

Variability In Soil Testing, Kenneth L. Wells, Vern Case

Agronomy Notes

Many factors can influence the accuracy of soil test results, ranging from field sampling technique, sample preparation, and quality control in the laboratory. Many people expect that if a field is sampled more than once, the soil test results should be identical. When identical results are not obtained from successive sampling, much concern about soil test reliability is of ten expressed.

We have analyzed soil test results from some controlled field experimental sites which help provide an understanding of variability which can occur naturally in the field, how various field sampling techniques influence soil test readings obtained, and how laboratories …

Kentucky County Soil Sample Summaries, Vern Case

Agronomy Notes

Samples are submitted through the county Extension offices for agronomic (Ag) crops, commercial horticulture, home garden/lawn, greenhouse media, and surface mining reclamation. The Mehlich III extractant (M-3) is used for routine determination of phosphorus (P), potassium (K),calcium (Ca), magnesium (Mg) and zinc (Zn). Amounts of these nutrients extracted are determined by either ICP methodology or by color for P and atomic absorption for K, Ca, Mg and Zn. Soil pH is determined on a 1:1 soil:water mix using appropriate electrodes and pH …

An Evaluation Of Twelve Maturity Group Ii Soybean Varieties At Lexington, Kentucky, Larry J. Grabau, Colleen C. Steele

Agronomy Notes

In both 1993 and 1994, the Kentucky Soybean Promotion Board funded an on-farm test of a small set of Maturity Group (MG) II varieties. Those studies showed that several MG II varieties were competitive with a high-yielding MG IV variety. However, other MG II varieties did not perform as well in those tests, indicating that variety selection is an important management consideration if this early maturing cropping system is to be successful in Kentucky soybean producers' fields. MG II varieties used in past University of Kentucky tests have been chosen based on their performance in university variety trials where such …
