Recently, the Q biotype of tobacco whitefly has been recognized as the most hazardous strain of Bemisia tabaci worldwide, because of its increased resistance to some insecticide groups. As an alternative control agent, we selected an Isaria javanica isolate as a candidate for the development of a mycopesticide against the Q biotype of sweet potato whitefly. To select optimal mass production med...
Barley is one of the most important cereals in animal nutrition and it has a role as a substitute source of wheat and rice in diet nutrition. This product is always exposed to damaging factors such as pests and diseases which lead to reduce yield and quality. The Powdery mildew agent, as a biotrophic fungus, seriously causes damage in some barley plantation areas. Similar to other plants, barle...
To evaluate the advantage of chickpea-barley intercropping systems under weed interference conditions, an experiment was conducted at the Agricultural Research Station, Faculty of Agriculture, University of Bu-Ali Sina, during 2010 growing season. Experiment was conducted as split plot base on randomized complete block design with three replications. Weed control treatment at two levels of weed...
this study investigated the effect of sowing date and limited water allocation management for single irrigation on the grain yield of rainfed barley. the experiment was a split-split plot arranged in a randomized complete block design with three replications from 2004 to 2006 at the main station of the dryland agricultural research institute at maragheh. the treatments comprised three sowing da...
Barley malting and brewing processing properties, as well as potential grain yield, morphology, physiological traits, and resistance to certain fungi and viral diseases are cultivar dependent. Therefore, reliable and simple method for variety recognition is of a great importance for the malting and brewing industries, as well as for barley breeders, growers and traders. Among various approaches...
Under irrigation and in double-cropping system, a large amount of plant residue remains after harvest that along with the limited time for residue decomposition and complete seedbed preparation, necessitates reduced tillage and special residue management. In the present study, the effects of various seedbed preparation methods on vegetative growth, yield components and seed and oil yields of su...
The objective of this study was to examine the ethanol yield potential of three barley varieties (Xena, Bold, and Fibar) in comparison to two benchmarks, corn and wheat. Very high gravity (VHG; 30% solids) fermentations using both conventional and Stargen 001 enzymes for starch hydrolysis were carried out as simultaneous saccharification and fermentation. The grains and their corresponding drie...
Early flowering is an important trait influencing grain yield and quality in wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) in short-season cropping regions. However, due to large and complex genomes of these species, direct identification of flowering genes and their molecular characterization remain challenging. Here, we used a bioinformatic approach to predict flowering-related...
Increased seed production has been a common goal during the domestication of cereal crops, and early cultivators of barley (Hordeum vulgare ssp. vulgare) selected a phenotype with a six-rowed spike that stably produced three times the usual grain number. This improved yield established barley as a founder crop for the Near Eastern Neolithic civilization. The barley spike has one central and two...
the recent decades emphasis on reducing pesticide use especially herbicide has led to increased interest in alternative weed control methods. the purpose of this study was to evaluate the hilling time and simultaneous interseeding of two cover crops as living mulch to control weeds in potato and to determine the impact of these actions on potato yield. a randomized complete block design as spli...
