introduction the demand for food and agricultural products are increasing in a line of population increasing in the world (alexandratos, 2003). it is possible to increase the quality and quantity of agricultural products via extending the farms and producing more products (astaaraei and koocheki, 1995). environmental problems caused by synthetic fertilizers and the high levels of producing and ...

this experiment was conducted in safi abad agricultural research center of dezful in order to study the effect of seed deterioration and plant density on germination, seedling establishment, yield and yield components of hull-less barley with in 2011- 2012. treatments included three levels of seed deterioration: (control, 72 and 96 hours) and five plant densities (100, 150, 200, 250 and 300 pla...

in order to evaluate the effects of organic, biological and chemical fertilizers on yield and yield components of milk thistle (silybum marianum l.), an experiment was conducted at the research station of ferdowsi university of mashhad based on complete randomized block design with three replications and six treatments during year 2007. treatments included inoculated seeds with azotobacter, com...

Objective: Chamomile is one of the commercial medicinal plants produced in Ethiopia. Besides, it is priority crop in national aromatic and medicinal plants research project in the country. As chamomile production affected by production techniques this activity was conducted to identify the effect of seed storage duration and seedling raising methods on its seedling establishmen...

adjustment of plant density is an important base on light, water and soil nutrients for increasing seed yield. to determine of plant density in new red bean lines (phaseolus vulgaris l.), this experiment was conducted as factorial in randomized complete block design (rcbd) with three replications at lordegan region (chaharmahal and bakhtiari province) in 2004-2005. factors were new red bean lin...

detopping in some plants reduces vegetative growth and increases transporting of photosynthate materials to specific sinks such as seeds. to study the effects of detopping removal and plant density on yield and yield components of faba bean (vicia faba l.), an experiment was carried out as a factorial arrangement based on a randomized complete block design with three replications at farm resear...
