A study was conducted in 2007 to investigate the effect of nitrogen fertilizer rates (0, 30, 60 Kg ha-1) on some agronomic characteristics, seed yield and oil percentage in three Sesame(Sesamum indicum L.) cultivars (Dashtestan, Darab 14, and Zarghan) in Kaki region (Bushehr Province). The type of design was completely randomized block with factorial arrangement and three replications. Nitrogen...
life cycle study of a product is an accepted method for determining the side effects of its production process on environment during its complete life cycle. in this research, the impacts of global warming, acidification, terrestrial eutrophication and fossil resources depletion per unit yield of wheat (ton) on environment were investigated using life cycle assessment method in marvdasht region...
In order to investigate the responses of promising bread wheat lines to different environmental conditions and determine of the stability of their grain yield, one experiment was done with 30 bread wheat genotypes and two commercial wheats as checks using alpha lattice design with four replications in six experimental research stations in southern warm and dry climatical zones in Iran (Ahvaz, ...

wheat streak mosaic virus (wsmv) causes extensive economic damage to wheat (triticum aestivum l.) in many regions of the world. the present study was conducted to find out if the variations in biochemical changes in reaction to wsmv infection in f2 generation of either potentially resistant (adl-cross) or susceptible (marvdasht) cultivars are genetically inherited. a factorial experiment was em...
The population parameters of sweet potato white fly, Bemisia tabaci (Genn.) (Hom.: Aleyrodidae), which is an important pest of cotton fields, were studied during 2001. The infected leaves containing nymphs and pupae were collected from Darab, Qom, Saveh, Gonbad, Gorgan, Varamin, Garmsar, Orsoiieh (Kerman), and Shooshtar cotton fields. Experiments were conducted in a growth chamber under 24±.2ºC...
in this research, amount of evaporation and transpiration and water requirement of wheat plant for marvdasht town (representation station: zaraghan) during 17-years statistical duration from 1989-2005 and properties of plant and soil are calculated using cropwat software. at the first, trends of dry and wet periods for mentioned station were determined using long-term average of climatic data (...
Nosema is a genus of microsporidia, which have significant negative impacts on honeybees. The aim of this study is the epidemiological evaluation and molecular characterization of Nosema spices in various counties of East-Azerbaijan province (Northwest of Iran). 387 samples were collected from colonies maintained in various counties of East-Azerbaijan province. Samples after preparation were ex...
Drought induced stress is one of the most significant environmental challenges. This study was designed to evaluate the effects of drought stress on crop yield and antioxidant systems during the vegetative period of wheat. The study was carried out in a greenhouse using factorial experiment based on complete randomized block design (RCBD) in three replications in Razi University in Iran from 20...
