Yield and Cost Effects of Plot-Level Wheat Seed Rates and Seed Recycling Practices in the East Gojam Zone, Amhara Region, Ethiopia: Application of the Dose–Response Model
Previous studies investigated the effects of seed rates and seed recycling practices on the yield and yield-related variables. However, higher yield does not always guarantee cost-efficiency. This study aimed to investigate ...
Yield gain due to fungicide application in varieties of winter wheat (Triticum aestivum) resistant and susceptible to leaf rust
In three independent experiments in Turkey and Kazakhstan, winter wheat germplasm with variable degrees of resistance to leaf rust was subjected to fungicide protection. The yield loss of genotypes susceptible to leaf rust ...
The association of biomass allocation with growth and water use efficiency of two Triticum aestivum cultivars
We investigated traits that might improve performance of wheat (Triticum aestivum L.) in a dry environment, and examined if the response to drought is different for cultivars with a contrasting biomass allocation pattern, ...
Effect of Tillage System on the Spontaneous Regeneration of Two Annual Medics (Medicago Spp.) After Wheat in North Syria
Four tillage treatments were applied to soil on which wheat was to be sown in 1988/89 after pastures of two annual medics, Medicago rigidula and M. polymorpha, had been established in 1987/88. Germination of the medics was ...
Evaluation of variation in Triticum dicoccum for wheat improvement in stress environments
A collection of accessions of cultivated emmer wheat, Triticum dicoccum, was evaluated for economically important traits at Tel Hadya in northern Syria. Useful variation among and within accessions was detected for agronomic ...
Analysis Of Genotypic Variation For Normalized Difference Vegetation Index And Its Relationship With Grain Yield In Winter Wheat Under Terminal Heat Stress
Normalized difference vegetation index (NDVI), which is a measure of leaf greenness (chlorophyll content), is considered to be correlated with crop productivity. This study was conducted to examine genotypic variations for ...
Phosphorus Use Efficiency of Wheat Genotypes Grown in Calcareous Soils
Phosphorus (P) deficiency and low P-use efficiency are induced by soil properties, especially in calcareous soils, which are dominant in semi-arid regions of the world such as the Mediterranean region. Alternative approaches ...
Distribution of Sunn Pest, Eurygaster integriceps Puton (Hemiptera: Scutelleridae), in overwintering sites
Sunn Pest, Eurygaster integriceps Puton (Hemiptera: Scutelleridae), is the most serious pest of wheat in West and Central Asia. Following harvest, the pest migrates from wheat fields to high elevations to escape high summer ...
Harvest index is a critical factor influencing the grain yield of diverse wheat species under rain-fed conditions in the Mediterranean zone of southeastern Turkey and northern Syria
Environmental and plant factors critical to the grain yields of bread (Triticum aestivum L.), durum (T. durum L.) and emmer (T. dicoccum L.) wheat cultivars were investigated at two Mediterranean rain-fed eld sites: Adana ...
A Massive Expansion of Effector Genes Underlies Gall-Formation in the Wheat Pest Mayetiola destructor
Gall-forming arthropods are highly specialized herbivores that, in combination with their hosts, produce extended phenotypes with unique morphologies [1]. Many are economically important, and others have improved our ...
