The present study assessed the effect of seed inoculation with single or multiple plant growth-promoting rhizobacterial (PGPR) strains on yield in spring wheat (Triticum aestivum spp. vulgare var. Kırık) and barley (Hordeum vulgare cv. Tokak) plants in both greenhouse and field conditions during the years 2007 and 2008. The treatments of wheat and barley plants during the first year include...

Earth observation data, owing to their synoptic, timely and repetitive coverage, have been recognized as a valuable tool for crop monitoring at different levels. At the field level, the close correlation between green leaf area (GLA) during maturation and grain yield in wheat revealed that the onset and rate of senescence appeared to be important factors for determining wheat grain yield. Our s...

low nitrogen (n) use efficiency is considered to be one of the major problems in wheat production fields all over the world. this experiment was conducted to evaluate the effects of nitrification inhibitor (ni) 3, 4- dimethylpyrazole phosphate (dmpp) on the yield and nitrogen use efficiency of spring wheat (triticum aestivum l.) cv. bahar during 2011 at shahrekord university. a factorial experi...

delay in irrigated wheat primary tillage operations causes yield reduction and hidden timeliness cost in fars province. mechanization of primary tillage operations for irrigated wheat in fars province was simulated using system dynamics approach. a part of the model structure was related to the agricultural operations timeliness costs. for the mentioned simulation, causal relations between syst...

drought stress is one of the most important abiotic stresses which can affect the growth of a plant, thereby curbing crop yield. identification of effective morphological traits is the main aim of each breeding program. our objective was to identify agronomic traits associated with changes in grain yield of wheat under irrigated and drought conditions. to address this objective, grain yield and...

Remobilisation of non-structural carbohydrates (NSC) from leaves and stems and unloading into developing grains are essential for yield formation of rice. In present study, three recombinant inbred lines of rice, R91, R156 and R201 have been tested for source-flow-sink related attributes determining the nature of NSC accumulation and translocation at two nitrogen levels in the field. Compared t...
