The chances of raising crop productivity to enhance global food security would be greatly improved if we had a complete understanding of all the biological mechanisms that underpinned traits such as crop yield, disease resistance or nutrient and water use efficiency. With more crop genomes emerging all the time, we are nearer having the basic information, at the gene-level, to begin assembling ...
Long-term feed withdrawal has been shown to increase ileocecal intestinal colonization and fecal shedding of Salmonella enterica serovar Enteritidis in challenged hens. Less information is available regarding effects of fasting on crop colonization. Two trials were conducted to compare effects of 14-day feed withdrawal vs. full feed on crop colonization in hens challenged with Salmonella Enteri...
Canopy characterization is a key factor to improve pesticide application methods in tree crops and vineyards. Development of quick, easy and efficient methods to determine the fundamental parameters used to characterize canopy structure is thus an important need. In this research the use of ultrasonic and LIDAR sensors have been compared with the traditional manual and destructive canopy measur...
A number of crop products generated by using biotechnology have been introduced to the marketplace. These biotechnology products have been carefully evaluated for their overall safety from an agronomic, environmental, performance, and equivalence perspective, and the safety of the newly expressed protein(s). One aspect of the safety evaluation is the question concerning potential allergenicity....
Genomic selection (GS) is a promising approach exploiting molecular genetic markers to design novel breeding programs and to develop new markers-based models for genetic evaluation. In plant breeding, it provides opportunities to increase genetic gain of complex traits per unit time and cost. The cost-benefit balance was an important consideration for GS to work in crop plants. Availability of ...
In order to assessment of quality traits of durum wheat lines, 18 elite lines selected from advanced regional durum wheat yield trial, ARDYT (2009-10) along with two check {including Dena(durum wheat) and Parsi (Bread wheat)} were studied in an experiment using RCBD with three replications at Isfahan research station in two consecutive crop season. Results showed a significant difference betwee...
Eggplant is a crop that has been cultivated for a long time in different areas of Iran. Nevertheless, no sufficient studies have been done on variation of morphological traits and yield of this crop in Iran, and it has not been well-attended in breeding programs. Therefore, to study genetic diversity in collected local varieties, the experiment was conducted in a Randomized Complete Block Desig...
The production costs of agricultural enterprises 43 rural areas in the South Russia, which systematically cultivate same types crops: winter and spring grains, pulse crops, maize, sunflower, potatoes open field vegetables, has been investigated. Mathematical tools for cost forecasting long-term planning most competitive species profitable sales on world (grain) domestic product markets are shown.
