Leaf diseases’ influence the relationship between the yield and yield components of winter wheat (Triticum aestivum L.). Field experiments were conducted during 2003–2006 on a light loamy gleyic cambisoil in the central part of Lithuania to determine how leaf disease severity level affects grain yield and yield components. The area under disease progress curves (AUDPC), grain yield and yield co...

in order to compare the agronomic characteristics of developed iranian spring wheat genotypes (selective cultivars from: endemic landraces of wheat, interal hybrid wheat and international centers) and also the identifying traits affecting grain production under different concentration of iron in the soil solution, a randomized complete block design with a split-plot arrangement with 30 wheat ge...

Water shortage and nitrogen (N) deficiency are the key factors limiting agricultural production in arid and semi-arid regions, and increasing agricultural productivity under rain-fed conditions often requires N management strategies. A field experiment on winter wheat (Triticum aestivum L.) was begun in 2004 to investigate effects of long-term N fertilization in the traditional pattern used for...

Azotobacter chroococcum is an important PGPR (Plant Growth Promoting Rhizobacteria) producing compounds needed for plant growth. The aim of this research was to study the effects of different native strains of Azotobacter chroococcum on growth and yield of wheat under greenhouse counditions. Seeds of spring wheat (Triticum aestivum L. var. Pishtaz) were inoculated with some Azotobacter chroococ...

Farming activities practiced on many Australian soils have resulted in substantial losses of soil organic matter (SOM), nutrient loss, soil structural degradation and declines in cereal yield and quality. Field trials, consisting of a legume or fallow phase followed by three wheat (Triticum aestivum L.) crops, were established on a degraded Ferric Luvisol (Red Earth) soil in New South Wales to ...

a three-year field experiment (2004-2007) was conducted on a silty clay loam soil at tajarak research station of hamedan to determine proper grain drill for wheat in hamedan dryland areas. in this study, three grain drills including: hamedani barzegar; sahalan kesht; and kesht gostar with wheat seed broadcasting and disking were used. the experiment was a randomized complete block design with f...

Bread wheat (Triticum aestivum) inflorescences, or spikes, are characteristically unbranched and normally bear one spikelet per rachis node. Wheat mutants on which supernumerary spikelets (SSs) develop are particularly useful resources for work towards understanding the genetic mechanisms underlying wheat inflorescence architecture and, ultimately, yield components. Here, we report the characte...

abstract in order to evaluate the effect of different nitrogen application methods on yield and yield components of winter wheat, a field experiment with split plot arrangement in completely randomized blocks design with four replicates was conducted in 2006. basal dressing in three levels (1- with no basal dressing, 2- strip and 3- distributing nitrogen fertilizer) as main plot and top dressin...

Abiotic stress tolerance in plants is pivotal to increase yield stability, but its genetic basis is still poorly understood. To gain insight into the genetic architecture of frost tolerance, this work evaluated a large mapping population of 1739 wheat (Triticum aestivum L.) lines and hybrids adapted to Central Europe in field trials in Germany and fingerprinted the lines with a 9000 single-nucl...
