In order to study the effects of wild mustard competition and different levels of nitrogen on effective traits of wheat yield, this research was conducted in Ahvaz, south west of Iran. The study was consisted of a split plot experiment, on the basis of Randomized Complete Blocks Design with three replications. Different levels of nitrogen (90, 150 and 210 kgN.ha-1) were assigned in the main plo...

Low zinc (Zn) availability and its absorption limit wheat production and quality of yield in calcareous soils. In order to identify Zn deficient stress tolerance in wheat, fifteen spring genotypes (Diyarbakir-81; Gediz-75; Svevo; Zenit; Amanos-97; Fuatbey-2000; Balcali-2000; Ceylan-95; Firat-93; Aydin-93; Ozbek; Artuklu; Akcakale-2000; Aday-19; and Ege-88) were evaluated under two conditions (n...

in order to determine the practical method to predict economic production of wheat in competition with feral rye by using regression models, a factorial experiment was carried out based on randomized complete block design with three replications in dargaz. iran. experimental factors were included wheat cultivars (sayson, alvand, chamran and sepahan) and feral rye densities (0, 20, 40, 60 and 80...

the new cereal, primary tritipyrum lines, is an artificial hexaploeid wheat (2n=6x=42, aabbebeb) from crossing between triticum durum (2n=4x=28, aabb) and thinopyrum bessarabicum (2n=2x=14, ebeb) species. in this study the salt tolerant potencial of new primary tritipyrum lines for nacl (0, 100, 200 mm) in an hydroponic experiment was studied in a completely randomized split plot design with th...

this experiment was laid out in order to evaluate the effects  of different biofertilizers on yield components of barley. the experiment was a factorial design with three replications. treatments were three nitrogen biofrtilizers (nitroksin, nitrokara and supernitroplass) and three phosphate  biofrtilizers (phosphate barvar2, biozarr and superplass) with control for them and yield components we...

BACKGROUND: Fertilizer management plays an important role for obtaining satisfactory yields and to increase crop productivity. Nutrient management may be achieved by the involvement of organic sources, bio fertilizers, and micro-nutrients. OBJECTIVES: Assessment effect of chemical and biological fertilizer on seed yield, its components and plant height of...

this experiment was conducted to investigate and evaluate the phenotypic and genotypic diversity of a population including of 94 doubled-haploids lines, their parents and five iranian local bread wheat (triticum aestivum l.) cultivars. thirteen agronomic and morphologic traits were recorded including; grain yield per unit area, harvest index, spike length, seed number per spike, spikelet densit...

in order to study genetic diversity and detection relationship among agronomy traits, 169 barley recombinant inbred line (generation=rils) and their parents “igre” and “arigashar”, were planted in a simple lattice design with two replications. ten agronomic traits were scored on three randomly selected plants. the purpose of this study was detection of phenotype and genotype correlation between...
