the influence of leaf pubescence of three wheat cultivars (pishtaz, ghuds and falat) on preference and biological parameters of sipha maydis (passerini) was investigated under greenhouse conditions (25 ± 2 °c, 70 ± 10% rh and 14: 10 h (l: d) photoperiod). the results showed that pishtaz had a greater density of trichomes compared to the other cultivars. in the preference test with whole plant, ...

Black rice (Oryza sativa L.) contains high concentrations of bioactive compounds that are associated with human-health benefits. Arbuscular mycorrhizal fungi (AMF) can increase plant performance and these compounds. In a pot experiment, the effects four different species AMF (Claroideoglomus etunicatum; Rhizophagus variabilis; nov. spec.; Acaulospora longula) were assessed on growth performance...

this experiment was conducted to evaluate rate and duration of grain filling among old, modern and promising rice cultivars under different nitrogen levels in fields of  sari agricultural sciences and natural resources university, during 2008. two factors consisted of different urea fertilizer (0, 100 and 200 kg ha-1) as main plot and four promising lines (jelodar, partou, danesh and jahesh), 2...

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...

To survey the effects of flooding during the reproductive growth stages of aerenchyma formation and ethylene production in soybean cultivar DPX experiment  the completely randomized factorial was in 2012 in Gorgan University of Agricultural Sciences and Natural Resources. Factors examined include nutrition levels in three levels (1 - inoculated with bacteria JaponicumBradyRhizobium 2 - non-inoc...

an experiment was conducted as a split plot based on complete randomized block design with three replications in the fall of 2010 at the farm of lorestan university, khorramabad, iran. four winter wheat cultivars (marvdasht, azar, shiraz and line m-79-7) as the main plot and levels of iron oxide nanoparticles (ion) along with control treatment were the subplot. iron fertilizer spraying was done...

In order to evaluate the effects of inoculants and chemical fertilizer on quantitative and qualitative yield, a bread wheat cultivar treated with Azotobacter, arbuscular mycorrhiza fungi (AMF) and nitrogen sources by using split plot on the basis of randomized complete block design with three replications in Fars Agricultural Research Station during 2007-2008. Main plots consisted of nitrogen f...

this experiment was carried out to evaluate the effect of rhizobium strains and plant growth promoting rhizobacteria (pgpr) on dry matter partitioning and some growth parameters of chickpea (cicer arietinum l.) arman cultivar. this research was conducted as split plot based on complete random block design at zanjan university research farm. irrigation levels (optimum irrigation during season gr...
