This study was conducted to determine whether the irrigation of a furrowed field when water supplies are limited could be managed to increase field corn yield (Zea mays L) while conserving water. Strategies of delaying the first irrigation of the season, multiple irrigations, an…
The application of human waste on agricultural land has an ancient history. Its origin dates back several centuries in China. This study was concerned with the use of liquid digested sewage sludge as a fertilizer instead of commercial fertilizer to grow some Nigerian agricultura…
Sunflower oil has great potential as an alternative source of energy for farming operations. No suitable on-farm oil expellers are available to farmers which are specifically designed to express sunflower oil. The purposes of this study were to evaluate the various factors affec…
Design parameters and procedure for developing a small to medium capacity grain (rice) dryer, with natural convection air flow and using solar heat, was established by theoretical consideration, simulated performance evaluation and some experimental work. A mathematical model wa…
Currently, Egypt is faced with several fundamental problems; an ever-increasing population, a limited supply of cultivable land and a limited supply of water resources. These problems intensify the importance of developing efficient natural resource use strategies. There is stro…
Many studies have been conducted to quantify total dust emissions from confinement animal buildings, but the dust emission was not sufficiently addressed due to absence of standard measurement methods and a lack of representative data. This study investigated chemical, physical …
The growth of fungi on sugar rich wastes can be an economical way of producing citric acid. Nevertheless, conditions for the optimum production of citric acid still need to be established. Using Aspergillus niger , the objective of the present study was to measure the effect on …
A Helmholtz Coil with a large usable area of uniform field was designed, constructed and characterized, specifically for Bioelectrics studies. The Helmholtz coil was designed for use with both AC and DC power sources. The design and analysis of the coil were carried out through …
Concerns about phosphorus (P) excretion into the environment from livestock and poultry in concentrated animal feeding operations (CAFOs) have made it necessary to examine alternative methods in which to reduce the amount of P that is excreted by the animal without impairing per…
CliCrop is a simple 1-dimensional crop simulator for investigating both predicted future yields and possible solutions for future yield improvements. CliCrop is an immediate response to a study on Niger by the United States Agency for International Development (USAID), where the…
The commercial production system of Agaricus bisporus mushroom relies entirely on composting as a means to generate a mushroom-specific substrate, and all aspects of this traditional system are designed for the preparation, processing, and handling of this compost-based substrat…
With climatic change, many western states in the United States are experiencing drought conditions. Numerous irrigation districts are losing significant amount of water from their canal systems due to leakage. Every year, on the average 2 million acres of prime cropland in the U…
Poultry litter is an important nutrient source in crop production. However, the traditional practice of broadcasting poultry litter on the soil surface could result in nutrient losses in runoff as well as substantial ammonia volatilization losses, which could adversely affect bo…
The effects of aflatoxin B1 (AFB1 ) in turkeys is well documented; however, the specifics of AFB1 metabolism in this species have not been investigated. The extreme sensitivity of turkeys to the hepatotoxic effects of AFB1 makes them an ideal candidate for chemoprevention studie…
This research was conducted to assess the feasibility of turkey processing wastewater treatment with a sand filter system. The effects of operational parameters such as hydraulic and organics loadings, filter design, dosing frequency, and detergent as an additive on the treatmen…
The agricultural sector can play a vital role in the economic development of the less developed countries (LDCs) by providing food and income for the people-capital, labor and raw materials for industry. The strategies adopted by various LDCs in selecting appropriate means of ac…
