Small Scale Temporal And Spatial Variability Of Potassium Soil Test Values On A Crider Soil, Kenneth L. Wells, James E. Dollarhide, Frank J. Sikora

Agronomy Notes

An on-farm, small plot study conducted in 1996, on a Crider soil in Larue County, Kentucky, resulted in unanticipated wide variability of soil test potassium (STK) values between spring and fall sampling. Because of this, the small plots were sampled monthly over a period of time with the objective of determining if such variability in STK values was real.

Evaluation Of 4 Small Doses Of Fertilizer In Growing Maize (Zea Mays L.) In Two Communities Of San Juan Ermita, Chiquimula, Victor Estuardo Villalta Garcia

Theses and Dissertations

Corral de Piedra and Salitron are two communities located in the municipality of San Juan Ermita, which is in the department of Chiquimula, Guatemala. In both communities, the land has very sloped topography with slope grades ranging from 12 to 55%. Agriculture is the main production activity with corn (Zea mays L.) and beans (Phaseolus vulgaris) being the crops of greatest economic importance. These crops are planted through a system of sequential association commonly called relay. First, corn is planted at the beginning of the rainy season (May or June). Once it has completed its reproductive cycle, beans are planted …

Evaluation Of Forty-Two Corn (Zea Mays L.) Genotypes And Their Tolerance To Drought In Chiquimula, Servin Ardany Flores Galdámez

Theses and Dissertations

The Corral de Piedra community is located in Chiquimula, Guatemala. The main agricultural activities are corn and bean production, small-scale gardens, and small animal production, such as poultry and pigs. The crop areas are predominantly located on lands with slopes between 12 and 55%, presenting low fertility conditions and poor moisture retention capabilities. In addition, local crop varieties have low productivity potentials and the winter season is characterized by poorly distributed and erratic periods of rain. The Benson Institute introduced a technology transfer model to increase and diversify agricultural production, while preserving current natural resources. An integral part of this …

Strepsipteran Parasitism Of White Leafhoppers, Cofana Spp. (Hemiptera: Cicadellidae) In Lowland Rice In Côte D’Ivoire, I. O. Oyediran, A. Ndongidila, E. A. Heinrichs

Department of Entomology: Faculty Publications

Three tests were conducted over a 2-year period in lowland irrigated rice fields on the WARDA Research Station at Bouaké, Côte d’Ivoire, to obtain information on the strepsipteran parasitism of white leafhoppers, Cofana spectra and C. unimaculata. Rice cultivars were sampled with a sweep net to collect leafhoppers for determination of the relative abundance of the two leafhopper species and the effect of rice cultivar and rice crop age on the leafhopper populations and percent strepsipteran parasitism. Dissections of the leafhoppers were made to determine the relative number of the various parasitic stages in the leafhoppers. Cofana unimaculata populations …

Crop Quality And Utilization: A Twelve-Hour In Vitro Procedure For Sorghum Grain Feed Quality Assessment, Jeffrey F. Pedersen, Todd Milton, R. A. Mass

Department of Agronomy and Horticulture: Faculty Publications

Improvedmethods for assessing cereal crop feed value are a prerequisite for the genetic improvement of sorghum [Sorghum bicolor (L.) Moench] feed value. Rate of starch digestion is now commonly believed to be the limiting factor in sorghum utilization by cattle (Bos taurus). However, techniques to assess this trait are not useful to sorghum breeders because of high labor inputs, lab error associated with starch measurement, and need for high numbers of replications. The objective of this study was to develop a simple technique capable of identifying differences in digestion between sorghum and corn (Zea mays L.) …

Ethylene Production, Cluster Root Formation, And Localization Of Iron(Iii) Reducing Capacity In Fe Deficient Squash Roots, Brian M. Waters, Dale G. Blevins

Department of Agronomy and Horticulture: Faculty Publications

Dicots and non-graminaceous monocots have the ability to increase root iron(III) reducing capacity in response to iron (Fe) deficiency stress. In squash (Cucurbita pepo L.) seedlings, Fe(III) reducing capacity was quantified during early vegetative growth. When plants were grown in Fe-free solution, the Fe(III) reducing capacity was greatly elevated, reached peak activity on day 4, then declined through day 6. Root ethylene production exhibited a temporal pattern that closely matched that of Fe(III) reducing capacity through day 6. On the 7th day of Fe deficiency, cluster root morphology developed, which coincided with a sharp increase in the root Fe(III) …

Determination Of Chilling Requirement Of Arkansas Thornless Blackberry Cultivars, Chrislyn A. Drake, John R. Clark

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Little research has been done to determine the chilling requirement for blackberry cultivars. However, field observations from areas where fewer hours of chilling occur indicate that ‘Navaho’ requires more hours of chilling than does ‘Arapaho’. The objective of our study was to determine a method for measuring the chilling requirement using whole plants of two blackberry cultivars, Arapaho and Navaho. One-year old, bare-root plants were field-dug on 26 October 1999 and placed in a cold chamber at 3ºC. Ten single-plant replications of each cultivar were removed at 100-hour intervals up to 1000 hours. The plants were potted and placed in …

Bulletin 4396 - Byenup Hill Focus Catchment Benefit: Cost Analysis, Allan Herbert

Bulletins 4000 -

The main text of this document concentrates on the costs of the proposed strategies, and the on-farm financial benefits from forecast production changes - in particular the production differences between the 'do nothing' and 'with strategy' scenarios.

Members of the catchment group indicated however that their main focus was on preserving their capital base. Hence some discussion of the values of land lost to salt and premiums/discounts for 'landcared' vs 'unlandcared' land appears later in the report. Economics literature suggests that including changes in land values into these analyses is incorrect. It is argued that production differences are actually captured …
