Soybean (Glycine max [L.] Merr.) establishes a symbiotic relationship by infection with soybeannodulating bacteria and subsequent root nodule formation. Soybean acquires atmospheric nitrogen as ammonia through the symbiotic nitrogen fixation by soybean-nodulating rhizobia in the root nodules. The inoculation of soybean with bradyrhizobia that has high ability of nitrogen fixation is considered ...

Soybean meal is considered the “gold standard” among intact protein sources used in the feed industry (Cromwell, 1999). It has an excellent amino acid profile that complements cereal grains in diet formulation, as methionine is typically the only limiting amino acid for poultry. Soybean meal is characterized as either from dehulled beans or beans having hulls (NRC, 1994). Dehulled soybean meal ...

It has been established that maize/soybean intercropping can improve nitrogen use efficiency. However, few studies have addressed how affects nitrogen-fixing bacterial diversity and N fixation efficiency of intercropped soybean. In this study, communities, efficiency, their relationships with soil properties under three fertilization application rates (N0 0 kg/ha, N1 40 N2 80 kg/ha) were explor...

In this paper, as raw material, soy protein, amino nitrogen content as an indicator to determine the microwave heating three enzymes (alkaline protease, papain, pepsin) in cooperation with means of enzyme hydrolysis of processing the order and the preparation of small molecule soybean peptides best process Conditions.Measured by fluorescence analysis AN, dextran G-50 gel chromatography separati...

Commercially prepared and packaged soybean ::md cottonseed salad oils from several different processors were evaluated penodically during storage for 12 months. Panially hydrogenated and winterized soybean oils, as well as unhydrogenated soybean salad oils. were stored in bottles and cans at i8 and 100 F. Control samples of all oils were held at a F during the entire test. Some lots in bottles ...

in the first phase of this research, adaptability of winter rapeseed (brassica napus l.) varieties were investigated to select high yielding rapeseed cultivars. accordingly, two field experiments were performed in 2006-2007 and 2007-2008 cropping seasons at experimental field of agricultural and natural resources research center of markazi province, in arak, iran, in a randomized complete block...

In the north central United States, populations of the exotic soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), are highly variable across space, complicating effective aphid management. In this study we examined relationships of plant nutrients, landscape structure, and natural enemies with soybean aphid abundance across Iowa, Michigan, Minnesota, and Wisconsin, representing the ...

Nitrogen absorption from the large intestine, largely as ammonia and possibly as amino acids (AAs), is generally thought to be of little nutritional value to nonruminant animals and humans. Ammonia-nitrogen absorbed from the large intestine, however, may be recycled into the small intestine as urea and incorporated into microbial AAs, whichmay then be used by the host. A cecal infusion study wa...

parsley has a very high nutritional value, containing a, b and c vitamins and mineral nutrients. in order to investigation of the effect of different nitrogen sources on parsley an experiment conducted in a factorial combination of three nitrogen forms (calcium nitrate, ammonium sulphate and urea) and four nitrogen levels (0, 100, 125, 150 kg ha-1) by using a factorial experiment based on rando...

Coastal erosion is increasing worldwide due to the frequency of extreme natural phenomena and excessive human exploitation. In this study, a small model experiment was conducted investigate solidification effects three enzyme sources—soybean urease, freshwater Bacillus pasteurella, seawater domesticated pasteurella—on coastal sediments their impacts in environment. The solidifying effect differ...
