to study the effects of below leaves excision and nitrogen application on stomatal characteristics of wheat flag leaf, grain protein, dry matter remobilization, grain yield and yield component, leaf area of winter wheat (t. aestivum cv. ghods) was artificially reduced under filed condition. the experimental design was a factorial on a rcb with 3 replications, a combination of three levels of de...

To obtain high concentration of ethanol from cellulose, corncob was pretreated with acid and alkali to remove non-cellulose components, and then subjected to simultaneous saccharification and fermentation (SSF). An ethanol concentration as high as 69.2 g/L was achieved with 19% dry matter (DM) using batch SSF, resulting in an 81.2% overall ethanol yield. A fed-batch process using a high solid c...

There is limited knowledge on the inheritance of agronomic traits in cassava and the importance of epistasis for most crops. A nine-parent diallel study was conducted in subhumid environments. Thirty clones were obtained from each F1 cross. Each clone was represented by six plants, which were distributed in three replications at two locations. Therefore the same 30 genotypes of each F1 cross we...

Barley, Hordeum vulgare L., is well adapted to subarctic Alaska growing conditions, but little is known about its response to grasshopper defoliation. A field experiment was conducted to study dry matter and grain yield in response to a combination of grasshopper defoliation and weeds in 2002 and 2003 near Delta Junction, AK (63 degrees 55' N, 145 degrees 20' W). Barley plants at third to fourt...

technique of remote sensing and its satellite products has many implementations in agricultural science and national resources. in this study, wheat yield in esfahan province, iran, were derived from modis satellite data over periods of 2000-2001(dry year) and 2004-2005 (wet year). for this purposes, 68 modis products of surface reflectance (mod09ga) and land surface temperature lst (mod11a2) o...
