in order to evaluate the effects of drought stress and planting method on some physiological and biochemical characteristics of two chickpea cultivars (cicer arietinum l.) an experiment was conducted at the research station of college of agriculture, shiraz university using a split factorial based on randomized complete block design in four replications. the main factor was stopping irrigation ...

ِdfferent drip (surface and subsurface) and furrow irrigation methods effects on grain, oil and water use efficiency based on grain black cumin(nigella sativa l.) as medicinal plants was investigated. for this purpose, experiment over the past two years (2009 and 2010) in a randomized complete block was designed in three replications. treatments in this research were consisting of 50, 75 and 100...

this experiment was conducted at the agricultural research farm of isfahan university of technology in 2007-2008 to evaluate the effects of seed treatment and the levels of irrigation regimes on three safflower cultivars. a split plot factorial arrangement was used in a randomized complete block design with three replications. main-plot consisted of three irrigation regimes (60, 105 and 140 mm ...

peppermint (mentha piperita l.) from lamiaceae family is one of the most important medicinal plants, used in food, sanitary and cosmetic industries. a field experiment was carried out in ferdowsi university of mashhad in 2010-2011 to evaluate the effects of three irrigation levels (100, 80 and 60 percent of water requirements calculated by evaporation pan class a) and two mulch types (black pla...

in order to study the effects of drought stress on yield and yield components of safflower genotypes, a split plot based on randomized complete block design with four replications was performed at the research field, islamic azad university, arak, iran during summer of 2009. irrigation treatments included three levels of 100, 75 and 50% crop water requirement and four levels of safflower genoty...

deficit irrigation is an essential optimization method for water consumption in irrigated lands. in order to investigate the effects of deficit irrigation on growth, yield and quality traits of two tomato (lycopersicon esculentum mill.) cultivars a factorial layout based on randomized complete block design with three replications was conducted in agricultural research station of miandoab during...

BACKGROUND: Nutrients play a very important role in chemical, biochemical, physiological, metabolic, geochemical, biogeochemical, and enzymatic processes. Innovations for saving water in irrigated agriculture and thereby improving water use efficiency are of paramount importance in water-scarce regions. Conventional deficit irrigation is one approach that can reduce water use w...

in order to investigate the effect of irrigation and nitrogen fertilizer on yield and yield components of (anethum graveolens l.), a field experiment was performed in agricultural research farm of the university of tabriz, iran, during growing season of 2009-2010. the experiment was carried out as split plot based on randomized complete block design with three replications. irrigation treatment...

with population growing throughout the world, it is necessary to optimize water use,especially in agricultural lands. in order to conduct technical and economical evaluation ofdrip and furrow irrigation methods under deficit irrigation of cotton, a field experiment wascarried out during 2010 growing season at experimental farm of orzoueyeh agricultural andnatural resources research center in ke...

In order to study the effect of water deficit stress and different nitrogen levels on flower yield, yield components and water use efficiency of Calendula officinalis L., an experiment was conducted as split plot based on randomized complete block design with three replications, at research field of Islamic Azad University, Birjand branch in 2009. In this experiment, irrigation treatments (irri...
