The 13 topics covered in this publication are all integral parts of a successful carrot management program. Each topic is designed to focus on a particular aspect of production and provide the latest management technology for that phase of production. It is hoped that the information contained in this publication will assist growers in improving profitability in carrot production.
This publication represents the latest information available on the commercial production of short-day onions in South Georgia.
This publication is a comprehensive guide to growing vegetables organically, including location, planning, irrigation, soil preparation, composting, fertilizers, successive planting and crop rotation, mulching and insect control.
Annuals are the mainstay color plant of many home gardens. They are also used in increasingly large numbers in commercial and municipal landscapes because they provide landscape color in a very short time with minimal investment. Properly cared for, many annuals will brighten the landscape continuously from spring until frost kills them in the fall.
This publication includes three parts. Part 1 discusses stormwater as a pollution source for streams and water bodies, and provides a background on why rain gardens in our landscapes have great environmental value. Part 2 includes a thorough definition of rain gardens and their purpose, and gives step-by-step instructions on how to design a rain garden for a specific site. Part 3 discusses appropriate plants to use in rain gardens.
An Excel workbook, Nutritional Response Determination Optimization (NuRDO). has been developed to simulate the optimal number or nutrient levels and replicates per level when planning nutritional requirement studies. With NuRDO, researchers can simulate data from what they think is the real shape of the response curve. They can then run up to 1,000 simulated experiments to see the combination of levels and replications that minimize the standard error or the requirements and other parameters for the broken-line models. SK and hyperbolic models. For example, consider the BLL model with a "true" requirement (REQ) of 5.2, a maximum of 99 units, a rate constant of 18.6 and a CV of 10%:For 5 input levels and 10 reps per level, the estimated REQ ± SD is equal to 5.196±0. 106, for 10 levels & 5 reps each, the REQ is 5.231±0 .157. The workbook can be used in this manner to determine the best combination of levels and reps to improve the chances or getting the best results possible from experiments.
New feed ingredients are evaluated and introduced to the feed industry every year. The evaluation process is necessary and includes feeding birds different levels of the test ingredient to estimate the maximum safe level (MSL). The MSL is usually estimated with a multiple range test, ignoring the fact that this test is inappropriate for this type of feeding trials where the independent variable is continuous. This paper describes the use of the Maximum Ingredient Optimization Workbook (MIOW) in estimating the MSL and determining the optimal combination or ingredient levels and replications for most efficient experimental design of future feeding trials. The MIOW calculates the results and the related descriptive statistics (SD, SE, Cl, and R2) based on simulation and non-linear regression models (broken-line linear and broken-line quadratic models).
Pine shavings are the most popular bedding material used in poultry houses. Due in part to the expansion of the poultry industry, pine shavings are in short supply, and alternative bedding materials are being tested. Giant miscanthus grass (GMG) is one such material. GMG is a perennial grass that is dried and chopped into one-inch pieces for bedding. When compared to pine shavings, GMG is a good option for bedding material in poultry houses.
This publication is a joint effort of the seven disciplines that comprise the Georgia Vegetable Team. It is comprised of 14 topics on tomato, including history of tomato production, cultural practices, pest management, harvesting, handling and marketing. This publication provides information that will assist producers in improving the profitability of tomato production, whether they are new or experienced producers.
Lime mud is a by-product produced in pulp mills as part of the process that turns wood chips into pulp for paper. The pulp mill cooks wood chips with sodium hydroxide to extract the wood fiber used to make paper from the lignin that binds the wood together. During this process, sodium hydroxide is converted to sodium carbonate. The pulp mill than adds calcium oxide, also known as quicklime, to convert the sodium carbonate back to sodium hydroxide in order to use it again. In the process, calcium carbonate is formed.
