We surveyed nursery producers in New York to determine the extent, nature and economic impact of deer damage to their operations, and to assess their attitudes towards deer. Seventy-three percent of the producers experienced deer damage to their crops in 1988. Average costs for replacement were nearly $6,000 per grower for those reporting damage estimates (and over $8,000 if 1 extreme value was...

This paper focuses on an application of conjoint analysis within forestry economics. More specifically, it was used to determine eucalypt plant value perceptions among South African nurserymen, to assess the financial drivers of the eucalypt production system, and to attempt to quantify the trade-offs between attributes of a eucalypt nursery and the selling price of the plants. Utility function...

There is widespread concern among scientists and land managers that Phytophthora ramorum may be accidentally introduced into oak-dominated eastern U.S. forests through the transfer of the pathogen from infected nursery plants to susceptible understory forest species (for example, Rhododendron spp.) at the forest-urban interface. Inspection programs can be made more efficient by identifying loca...

Oil palm propagation techniques are juvenile pot plants derived from germinated seeds and tissue culture, because it doesn’t produce sucker. In the nursery stage, monitoring the conditions of irrigation and nutrition are important to ensure phenotypic quality. During the nursery stage, optimal fertilization in development of more vigorous and productive plants. This research was carried out to ...

INTRODUCTION There has been considerable debate over the impact of invasive exotic plants and the best approach to address this problem. The problem, briefl y, is that some nonnative plants are weedy to the point of being invasive, i.e., they naturalize over large areas, displace native plants, and disrupt natural ecosystems (Westbrook, 1998). There are many examples of exotic plants that fi t ...

Production of nursery crops in the US is accomplished in containerand field-growing conditions, with propagation and seedling-rearing carried out in greenhouses; 11% of the US national farm-product is represented by these crops. Container-grown crops represent 60% of the US market and represent a highly labor-intensive and thus costly segment of ornamental crop production. The USDA, NASA and th...

This research was carried out in Southeast of Tunisia in 2009 and 2010, in order to study the propagation of six (Ficus carica L.) cultivars by using hardwood cuttings under the field conditions. The effect of the cultivars and the type of buds, shoots age, shoots length, and shoots diameter were recorded. Ten cuttings per cultivar and/or cutting types with three replications were planted in ro...

1 Part 340 regulates, among other things, the introduction of organisms and products altered or produced through genetic engineering that are plant pests or are believed to be plant pests. The introduction into the United States of such articles also may be subject to other regulations promulgated under the Plant Protection Act (7 U.S.C. 7701–7772) and found in 7 CFR parts 319, 330, and 360. Fo...

Samples of sorghum distillers dried grains with solubles (DDGS) were collected and analyzed to establish a nutrient database and evaluate the quality and consistency between and within 5 ethanol plants in Kansas and Texas. Each sample (n = 21) was analyzed for AA, DM, CP, crude fiber, crude fat, ash, NDF, ADF, trace minerals, and starch. Mean values (DM basis) were 0.88% Lys, 10.49% crude fat, ...
