recognition of soil water infiltration process is essential for improving irrigation efficiency, decreasing water losses and management of surface runoff. the aim of this research was to evaluate temporal variation of the kostiakove-louise infiltration coefficient parameters during a corn growing season. in this research, 16 irrigation events for 8 large scale furrow experiments were analyzed b...

in the current study an experimental/statistical approach addressing key mechanical properties (compressive, tensile and flexural strength) and impact resistance of such new fibers with inclusion of different volume of polyphenylene sulfide (pps) fibers has been carried out on 288 specimens. results from this study revealed that compressive, tensile and flexural strength exhibit a good fit with...

introduction legumes are important sources of good quality protein in diet of people and they are valuable as animals feeding. the seed of chickpea plant (cicer arietinum l.) contains essential protein sources, which plays a significant role in the human diet. among legumes the resistance of chickpea to dehydration conditions causes a higher productivity. chickpea has a moderate tolerance to dr...

to determine the yield stability, adaptability and analysis of the genotype× environment interaction of virginia tobacco, 15 hybrids of tobacco including 10 iranian and 5 international hybrids were evaluated in two different experiments (water stress and normal irrigation) using a randomized complete block design (rcbd) with three replications at two locations including rasht and tirtash tobacc...

There are two distinct reasons for making comparisons of genetic variation for quantitative characters. The first is to compare evolvabilities, or ability to respond to selection, and the second is to make inferences about the forces that maintain genetic variability. Measures of variation that are standardized by the trait mean, such as the additive genetic coefficient of variation, are approp...
