In southern nurseries, hardwood seedlings often grow so large that they are difficult to lift and plant. In a study at the Southern Hardwoods Laboratory, maleic hydrazide (MH) was tested as a means of halting height growth when seedlings reach suitable size. Seeds of green ash (Fraxinus pennsylvanica Marsh.) and Shumard oak (Quercus shumardii Buckl.) were nursery sown during the summer of 1961....

Several bioassays were conducted with young chicks and pigs fed phosphorus (P)-deficient corn-soybean meal diets. With diets for chicks containing .62% Ca and .42% P (.10% available P), graded doses of a citric acid + sodium citrate (1:1, wt:wt) mixture (0, 1, 2, 4, or 6% of diet) resulted in linear (P < .01) increases in both weight gain and tibia ash. Relative to chicks fed no citric acid, ti...

As green building material, fly ash is advantageous to solving the question of environmental protection and energy conservation. In this paper, combined with the author’s research production, the latest development of studies and applications of activation techniques of fly ash is summed up, which is being looked forward to being useful to researchers and engineers. The latest researches show t...

This study assessed differences in nutrient composition, physical characteristics, and xylo-oligosaccharide content with or without xylanase treatment by maize genotype the grain position on cob. Ten cobs each from sixteen varieties sowed same field were collected classified considering grain's cob (basal vs apical). The majority of physicochemical characteristics influenced an interaction betw...

for this reason the samples were obtained from three area in kerman province that cartivate corn in large amounts (giroft, kahnooj, baft).the amounts of samples were enough for both voluntary consumption and investigation of digestibility. after that samples had been chopped by electric chopper we sampled again from every sample and its chemical compositions were determined with standard method...

in order to study the combined and separate effects of phosphorus fertilizer, phosphate-solubilizing bacteria and mycorrhizal fungus on adjusting and reducing the loss of yield resulting from drought stress during the stage of growth of grain corn (sc704) an experiment was performed in aboureihan campus of the university of tehran, iran, during 2007-2008. the experiment was conducted as split p...

The objectives of this study were to determine the effect of using corn stover or three different wood-based bedding materials (kiln-dried pine wood chips, dry cedar chips, or green cedar chips) on airborne concentrations of NH, total reduced sulfides (TRS), CO, CH, and NO above lab-scaled bedded manure packs. Four bedded packs of each bedding material were maintained for two 42-d periods. Airb...

A system was developed for evaluation of protein sources in ruminant diets. Two steer growth trials were conducted to determine if the system would differentiate between protein sources. Corn cob, corn-based diets were supplemented with urea or a test protein: soybean meal (SBM), a SBM-bentonite complex (SBMB), direct-cut dehydrated (DCD) or wilted dehydrated alfalfa (WD) or corn gluten meal (C...

Effective methods for early detection of newly established, low density emerald ash borer (Agrilus planipennis Fairmaire) infestations are critically needed in North America. We assessed adult A. planipennis captures on four types of traps in a 16-ha site in central Michigan. The site was divided into 16 blocks, each comprised of four 50- by 50-m cells. Green ash trees (Fraxinus pennsylvanica ...
