an experiment was conducted as a split plot based on complete randomized block design with three replications in the fall of 2010 at the farm of lorestan university, khorramabad, iran. four winter wheat cultivars (marvdasht, azar, shiraz and line m-79-7) as the main plot and levels of iron oxide nanoparticles (ion) along with control treatment were the subplot. iron fertilizer spraying was done...

water shortage in the agricultural sector is currently a major challenge in crop production. the more efficient water usage is that which increases yield without increasing water use. thus, a determination of the water-yield relationship is essential. a field study was conducted to examine water-yield relations in three genotypes of soybeans, including optimum irrigation depth, a comparison of ...

in countries such as iran which will be faced water deficit as the main challenge in the future and the food production is going to be dependent to water recourses, wheat water-deficit tolerant and adapted genotypes release is one of the most important strategies under such a condition. in order to study the adaptation and terminal water deficit stress tolerance, fifteen bread wheat lines and c...

line yesevi-93 (cultivar abidar) was first introduced to dryland agricultural research institute (dari) through the international winter preliminary barley yield trials (iwpbyt) in 1994. it was selected as one the most high yielding lines based on observational and statistical trails (regional barley yield trials) carried out in different locations during 1997-2000. the average yield of abidar ...

Although the rice growth response to FACE (free-air CO2 enrichment) has been widely studied and is considered important within the scientific community, few studies have attempted to examine the effects of FACE on the yield of indica rice, which is typically the parent of indica hybrids in China. The effects of FACE on the yield, yield components, biomass, N uptake and leaf photosynthesis of Ya...
