salinity stress is one of the most important environmental constraints that have been limited agricultural production in iran. therefore, introducing suitable cultivars having desirable yield under salinity stress will lead to increase of production efficiency. in order to study the response of spring safflower cultivars to salinity, an experiment was carried out at the experimental station of ...

an experiment involving erosion simulation was conducted at the soil and water con-servation research center of the university of tehran. a split-factorial plot with four replications was designed. five soil desurfacing treatments of blank, 5, 10, 15, and 20 cm of soil surface removal (e0, e5, e10, e15, and e20) were carried out, respectively. fertilizer treatments were 0, 65, and 130 kg ha-1 o...

in order to investigate drought stress and plant density the yield, yield components and protein of spotted bean grain (cultivar talash), an experiment was carried out as split plots in randomized complete blocks with three replications in yasouj, in 2012. factors of the test including irrigation in three levels; without stress (control treatment), water stress in vegetative stage (interrupting...

application of biofertilizers is a crucial technique for reducing catastrophic effects of irregular utilization of chemical fertilizers. this experiment was carried out to evaluate the effects of rhizobium strains and plant growth promoting rhizobacteria (pgpr) on dry matter partitioning and some growth parameters of chickpea (cicer arientinum l.), arman cultivar. this research was conducted as...

in order to investigate the yield and quality of forage in intercropping barley and fennel, an experiment was carried out as split plot based on a randomized complete block design with three replications at the research farm of agriculture and natural resources of ramin university during growing season of 2012-2013. four treatments levels of nitrogen including: (0, 70, 140 and 210 kgn.ha-1) hav...

an experiment was carried out in 2008-2009 to study the correlation between the reaction to potassium chlorate and pathogenicity on some iranian isolates of macrophomina phaseolina, the causal agent of soybean charcoal rot. from among a total of 48 collected isolates from the major soybean cultivation areas of golestan, mazandaran, ardabil, and lorestan provinces, twenty four isolates were sele...

currently deficiency of raw materials and initiative resources caused an increasing need of cellulose industries to new lingo cellulose products and resources. kenaf as a fibrous plant is considered along with the other plant sources that their bast has suitable fiber. this experiment was carried out in split–plot form with 4 replication in order to evaluation effect of harvest time and genotyp...
