to evaluate the effects of plant growth promoting rhizobacteria (pgpr) such as azotobacter chroococcum, azospirillum lipoferom and brasilence and pseudomonas fluorescens and nitrogen fertilizer from urea source on yield and yield components of maize (zea mays l.) double cross hybrids (dc 370), a field experiment was carried out in a factorial experiment (5*3) in rcbd with 4 replications. bacter...

Foliar fertilization with nitrogen (N) is used to supplement soil N application in order to meet the high N requirements of crops (Oosterhuis and Weir, 2010). Urea is the most common foliar N source in cotton, due to its relatively low toxicity, quick absorption, and low cost (Maples and Baker, 1993; McConnell et al., 1998; Oosterhuis and Bondada, 2001). However, in the literature reports of yi...

Diabetes mellitus was induced in 32 out of 40 adult male albino rats using intravenous injection of 50 mg/kg BW of alloxan. Then, the diabetic rats were divided into four groups, three of which fed a diet containing 8 % BW ethanol (polar solvent), cyclohexane (nonpolar solvent) and ether (intermediate solvent) extracts of walnut leaf for 21 days. The fourth (positive control) group received a n...

the effects of inoculation of thiobacillus and the type of nitrogen fertilization (urea and ammonium sulphate fertilizers) on yield and yield components of rapeseed cultivars (okapi, slm 046 and reagent * cobra) were studied. the experiment was carried out as spilit plot factorial in randomized complete block design with 4 replications in shahrood university of technology. reagent * cobra culti...

Nitrogen is an important element in the life of a plant. A wide range of nitrogen-containing compounds is available in the world market, with different formulations and efficiencies. Urea is present in most fertilizer applications; however, nano-nitrogen products are becoming popular although there is only limited information on their field efficiency. Thus, this paper studied the foliar applic...

Nitrogen is a crucial nutrient affecting plant growth and development and its addition to the soil (as chemical or organic form) influences plant growth characteristics. One experiment was conducted as a factorial based on RCBD with two Chrysanthemum cultivars (‘Fred’ and ‘Angel’( and two N-fertilizer sources [Urea (750 and 1500 g/ha and Nitroxin 7.5 and 15 L/ha] used as fertigation method besi...

The objective of this study was to examine the effect of combining ruminally degradable and undegradable CP sources on ruminal microbial protein synthesis and postruminal N and amino acid (AA) flows in steers. Six steers fitted with ruminal, duodenal, and ileal cannulas were fed diets containing corn silage and high-moisture corn supplemented with urea, soybean meal (SBM), dry corn gluten feed ...

Ensiled rice straw using, water (RSW), molasses plus urea, and whey (RWh) were implied to investigate the ensiling processing on palatability nutritional value of compared untreated (URS). Using resulted in a significant (P < .05) progress fermentation coefficient, Flieg Score others. Protein water-soluble carbohydrates content increased RWh RMU. Gas cumulative with ERS incubation URS. In-vitro...
