Proper storage density affects the growth and rearing of fish. This experiment was carried out to investigate the effects of rearing densities on the growth and carcass composition of Caspian kutum (Rutilus frisii) fry and physicochemical factors of farming water. Fish were examined in five rearing densities (5, 10, 15, 20, and 25 fish/60 L of water) with three replications, and fed based on 8%...
To promote global food and ecosystem security, several innovative farming systems have been identified that better balance multiple sustainability goals. The most rapidly growing and contentious of these systems is organic agriculture. Whether organic agriculture can continue to expand will likely be determined by whether it is economically competitive with conventional agriculture. Here, we ex...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...

In the semi-arid area of West Texas, drinking water is a precious commodity. Drinking water sources include water from Lake Meredith and groundwater from the Ogallala Aquifer. Water usage in this area includes farming and irrigation, municipal use or cooling water for electricity generation. As population continues to grow and water usage increases, especially during periods of drought, the ava...
Precision farming aims to optimize field-level management by providing information on production rate, crop needs, nutrients, pest/disease control, environmental contamination, timing of field practices, soil organic matter and irrigation. Remote sensing and GIS have made huge impacts on agricultural industry by monitoring and managing agricultural lands. Using vegetation indices have been wide...
Broccoli is a food often consumed for its potential health-promoting properties. The health benefits of broccoli are partly associated with secondary plant compounds that have bioactivity; glucosinolates and phenolic acids are two of the most abundant and important in broccoli. In an effort to determine how variety, stress, and production conditions affect the production of these bioactive comp...
The present study describes two different methods for the preparation of superabsorbent polyacrylamide (PAAm) hydrogels for application in farming of sandy soil. The two methods were employed to induce the crosslinking of the polymer matrix. In the first method a PAAm paste was exposed to gamma rays, while in the second method the polymer was thermally treated in the solid phase. Crosslinked PA...
