In order to study effects of nitrogen fertilization and cultivars on some of traits of different barley an experiment was conducted at Isfahan in 2012. The experimental was split plot in a randomized complete block design with three replications. In this experiment, different levels of nitrogen in the main plots included four levels (0, 50, 100 and 150 N kg/ha (urea)) and barley cultivars inclu...

during 1997-1998, five different doses of emulsifiable mayonnaise oil (1 , 1.5 , 2 , 2.5 and 3 percents) and a control in three replications were tested against nymphal stages of olive psylla (euphyuura olivina) in late april (a few days before blooming) in a complete randomized block design. population densities of nymphal stages of pest were counted one day before and five days after oil appl...

salinity is one of the abiotic stresses and exploitation of heterosis could increase the crop yield and extend the stress tolerance, especially in salinity stress. in this research, a set of full diallel design involving 7×7 crosses from cultivars including flat, bam, ghods, roshan, arg, kavir and pishtaz were conducted in a randomized complete block design with three replications under both no...

This research had conducted to investigate light intensity effects on the lucky bamboo growth in Islamic Azad University, Abhar Branch. The experiment arranged as a complete randomized block design with five treatments (0.75, 1.14, 1.89, 2.29 and 4.09 mmol m-2 s-1) in ten replications. Results showed that 1.89 mmol m-2 s-1 had significant differences than other treatments. The higher level of r...

abstract in order to evaluate of yield and yield components of eight wheat cultivars against flix weed (descurainia sophia), an experiment was conducted using a factorial arrangement of treatments in a randomized complete block design with four replications during 2003-2004 growing season in varamin region. the wheat cultivars were tabasi, roshan, karaj2, azadi, niknejad, mahdavi, shiraz and pi...

objective: drought stress is most important factor which reduce root and shoot growth in crops. this study was performed in order to evaluate the effects of drought stress and zn fertilizer on root traits of four cultivars of chickpea. methods: experiment was laid out in a split plot-factorial using randomized complete block design with three replications. drought stress treatment stand in main...

  Abstract Two experiments with factorial arrangements on the basis of randomized complete block design in three replications were conducted in 2007 and 2008, to evaluate chlorophyll content index (CCI), fluorescence of chlorophyll, proline content and grain yield of three soybean cultivars (Williams, Zan and L17) under a non-saline (control) and three saline (3, 6 and 9 ds/m NaCl) conditions...
