in order to investigate the effects of different levels of nitrogen rate on yield and seed yield components of wheat cultivars, an experiment was conducted on araghi mahalleh (gorogan) research farm in 2008. treatments, nitrogen in the form of urea (0, 90, 180 and 270 kg/ha) and cultivars (tajan, falat and n81-18) were arranged as factorial based on randomized complete block design with four re...

hamoon is a new bread wheat cultivar derived from progenies of a cross made between falat and roshan. it is of spring habit and early maturity, 90-100 cm plant height, white spikes and thousand kernel weight of 40-45 gram. it is tolerant to lodging and environmental stresses(drought and salinity) as will as yellow rust. hamoon has hard grains of amber colour with averae protein content of 10.5%...

in this study, the susceptibility of twenty-nine tomato varieties to broomrape infection under glasshouse conditions was investigated. results showed that differences in susceptibility to infection were significant among tomato varieties. significant differences were in number and time of broomrape shoots emerging, broomrape dry weigh (shoots and tubercles) and growth and fruit yield of tomato....

consumption of whole-wheat breads prepared from high extraction flours is recommended because of their high content of fiber, vitamins, and minerals. despite the beneficial effects of these breads, they contain high amounts of undesirable compounds like phytic acid (pa) which is believed to negatively interfere with the absorption of some such nutrients as zinc (zn). wheat genotypes are differe...

the bird cherry-oat aphid, rhopalosiphum padi (l.) is a serious threat to several cereal crops. host-plant resistance to this aphid could be especially valuable in cereal crops pest management. therefore, we evaluated the development, survivorship, reproduction and population growth parameters of r. padi as resistance indices among six wheat cultivars, including gaskojen, tajan, falat, saysonz,...
