two year field experiment was carried out on two early maturing varieties of soybean (glycine max (l.) men.) bred in russia. the purpose was to investigate the possibility of production and to study the effects of nitrogen supply on soybean seed yield and yield components. a range of zero to 100 kg n ha in 1995 when plants suffered from water deficiency and zero to 100 kg n ha -1 in 1996 when p...

the genus hypericum is one of the most important medicinal plants that contain 17 species in iran, three of them are endemics. this paper reports the essential oil composition of eight hypericum species from iran. the essential oil analysis of a number of the studied plants has already been reported but their report from iran may be valuable for scientists.  samples collected from different pla...

in order to investigate the effects of organic, chemical and biological fertilizers on crude protein and oil yields and fatty acids composition in black seed (nigella sativa l.), a field experiment was conducted at agricultural research station of ferdowsi university of mashhad, iran, in 2009-2010. the experiment was arranged by using a complete randomized block design based on factorial arrang...

effect of seed priming on germination and seedling growth of sesame investigated under controlled conditions. the primed seeds with znso4 had the maximum germination percentage whereas the highest germination rate was observed in hydro-primed seeds. the treated seeds with peg showed the best growth of the seedlings and rootlet. the complementary field experiment was conducted to evaluate the ef...

In order to investigate the effect of micronutrients foliar application on seed yield and essential oil of black cumin, a field experiment was conducted based on Randomized Complete Block Design (RCBD) with three replications at the farmlocated in Naqadeh city, West Azerbaijan province, Iran, during 2015-2016 growing season. Treatments were separate application of Nano-Iron, Nano-Zinc and Nano-...

Worldwide demand for vegetable oil is projected to double within the next 30 years due to increasing food, fuel, and industrial requirements. There is therefore great interest in metabolic engineering strategies that boost oil accumulation in plant tissues, however, efforts to date have only achieved levels of storage lipid accumulation in plant tissues far below the benchmark to meet demand. M...

Cotton is an important crop in the world and is a major source of oil for human consumption and cotton meal for livestock. Cottonseed nutrition (seed composition: protein, oil, and minerals) determines the quality of seeds. Therefore, maintaining optimum levels of cottonseed nutrition is critical. Physiological and genetic mechanisms controlling the levels of these constituents in cottonseed ar...
