The main objective of this study was to determine the effects of vermicompost and amino acids on the qualitative and quantitative yield of chamomile. The experiment was conducted during the growing season of 2010 at the Alborz Medical Research Center. The Treatment groups consisted of vermicompost (0, 5, 10, 15 and 20 tons/ha) and the sprays of amino acids (budding stag, flowering stage, and bu...

poor wheat stand establishment is a major cause of yield loss, particularly in rainfed and poorly irrigated environments. seeds of eight wheat cultivars (triticum aestivum l.) including irrigated and rainfed varieties, belonging to three different climates of iran (hamedan as cold, karaj as temperate and sarpolzohab as warm climates) were primed using osmoprimig treatments through use of urea ,...

a four - year field experiment (1999-2002) was conducted on a silty clay loam soil at laklak research field of hamedan to determine the effects of crop residue management and plowing depth on soil fertility and wheat yield in a maize-wheat rotation. in this investigation, four corn residue managements were used consisting of 1) stalk shredding by maize stalk shredder 2) stalk shredding by disk ...

in order to evaluate the effects of foliar application of methanol and irrigation intervals on yield and yield components of chickpea cultivars a factorial experiment as split plots based on randomized complete block design with three replications was conducted in spring 2008 at the agricultural research station of ferdowsi university of mashhad. the treatments were 10 and 20 irrigation interva...

thepetroleum concentrations are contaminant important sources in the environment. hydrocarbon’s contaminants depend on their type and concentration can cause variable toxicity in soils, on the other hand, different kinds of plants also response concentration of contaminant differently, because of the diversity of physiological and morphological characteristics. in this study the effect of diffe...

the efficiency of oil extraction from oil seeds is affected by seed harvesting time, drying methods, seed storage conditions and finally the means of seed transportation to the factory. to determine the grain moisture content at harvest  and its effect on seed while on drying trails, (employing different canola dryers), a study was conducted in mazandaran province in 2009. a factorial complete ...
