Proteomics Study of Pre-Harvest Sprouting in Wheat
<p>Pre-harvest sprouting (PHS) of wheat (Triticum aestivum L.) is a condition characterized by the early germination of spikes during moist environmental conditions. PHS lowers yield, degrades the quality of grain and thus limits the profits of wheat producers groups. During this investigation, …

Risk and Return Comparisons of Pre-harvest Marketing Strategies
… paper analyzes risk and returns associated with pre-harvest corn grain marketing strategies for the state of Arkansas. Farming is characterized by a volatile environment. Numerous risks are taken by producers in order to provide commodities that are bought and sold by various parties in the …

WET PROCESSING OF FIBRE BLENDS CONTAINING PRE HARVEST RETTED FLAX
… peroxide/sodium persulphate was sufficient preparation for subsequent dyeing. Unfortunately, when laccase or laccase/mediator systems were used on the flax/wool blend, there was staining of the wool component which was not removed by subsequent bleaching. Further work is suggested to …

A Genetic Approach towards Modulating Pre-Harvest Pod Shatter in Brassica napus (Oilseed Rape)
Pre-harvest pod-shattering in Brassica napus (Oilseed Rape) is a serious agricultural and economic problem, with losses of 11-25% reported (Price et al., 1996) resulting in lost revenues of an estimated £66 million per annum for the U.K. alone. Reductions in this loss will provide benefits for both …

EVALUATION AND MODELING OF RISK FACTORS ASSOCIATED WITH MICROBIAL CONTAMINATION IN PRODUCE PRE-HARVEST ENVIRONMENT
… been traced back to contamination occurring at pre-harvest production level. The overall goal of this dissertation was to identify risk factors for produce pre-harvest contamination and develop models to predict the introduction, survival, and persistence of enteric foodborne bacteria in produce …

Pre-harvest and postmortem methods of decreasing the incidence and salvaging value of non-conforming beef carcasses
… beef carcasses, however, other methods of preventing non-conformity are necessary to research.

Understanding the genetic and physiological control of pre-harvest sprouting and pre-maturity amylase in UK wheat
Pre-harvest sprouting (PHS) and Pre-maturity amylase (PMA) are physiological defects in wheat grains that reduce their end-use quality. PHS is the precocious germination of grains before harvest while PMA is the accumulation of α-amylase in grains. Both traits are quantitative in their expression …

Shiga Toxin-Producing Escherichia coli: a Public Health Challenge in the Pre-Harvest Stage of the Farm-to-Table Continuum
… for maintenance of STEC in cattle farms. Prevalence may be further influenced by diet, distance to contaminated water-sources, wildlife contact, slurry application to pasture, and population density. Relevance in environmental contamination is expected proportional to the amount of STEC …

Evaluating the Cross-Contamination Risks of Salmonella and Generic Escherichia coli on Agricultural Ground Covers in Produce Pre-Harvest Production
… (FSMA) Produce Safety Rule (PSR) prohibits the harvest of dropped fruits and vegetables due to potential microbial contamination. Under the FSMA PSR dropped produce includes (i) produce that has detached from the parent plant and unintentionally contacts the ground and (ii) produce that is …

Evaluating Methods of Screening for Pre-Harvest Sprouting in Soft Red Winter Wheat and the Effect of Delayed Harvest on Flour Properties
High pre-harvest rainfall in 2006 caused significant pre-harvest sprouting (PHS) and weathering throughout the mid-Atlantic soft red winter wheat (SRWW) (Triticum aestivum L.) growing region. Sprouting and weathering caused decreased flour quality due to lowered dough viscosity and decreased …

Effects of Clearcutting with Whole Tree Harvesting on Woody and Herbaceous Plant Diversity After 17-Years of Regrowth in a Southern Appalachian Forest
… effects of clearcut regeneration with whole-tree harvesting on plant diversity. Three approaches were used to study changes in species composition and structure: (1) forest level, (2) stand level, and (3) diversity indices. Within each approach the forest was stratified into three horizontal …

The Stabilizing Effects of Sesame Oil Extraction Technologies on Seasonal Fluctuations in Food Consumption and Nutritional Status of Rural Farming Households in The Gambia
… takes its toll on women and children during the pre-harvest lean season. In 1995, the Small-Scale Sesame Oil Production project introduced an inexpensive, manual technology for edible oil extraction, called the ram press, to women in The Gambia. The overall aim of the project was to improve …

Establishment Method and Cultural Practice Effects on Sports Turf
… by four methods (soil-based sod, washed sod, pre-harvest aerified sod, and sprigs for warm season species only). Post-establishment treatments included core aerification (1.3 cm hollow tine cultivation twice annually) and no aerification, as well as topdressing rate (0.5 vs 2.5 cm annually). …

Oak regeneration after clearcutting on steep slopes in the ridge and valley province of southwest Virginia
… which had been the dominant oak species in most pre-harvest stands, had higher density of advance regeneration stems, higher frequency of stump sprouting, and greater sprout production per stump than scarlet or black oak two years after harvesting. However, shoot growth of advance regeneration …

Vegetation Responses to Seven Silvicultural Treatments in the Southern Appalachians One-Year After Harvesting
… treatments one growing season after harvesting were examined on seven sites in the southern Appalachian mountains of Virginia and West Virginia. Treatments included: 1) control, 2) understory control by herbicide, 3) group selection, 4) high-leave shelterwood, 5) low-leave …
