this study was carried out in the agro-industry complex of gohar kouh, khash in iranshahr. a split-plot experiment based on rcbd was employed with three irrigation intervals including 1: 30 day interval 2: 40 days of irrigation interval 3: 60 day irrigation interval along with three levels of nitrogen application including 1: no nitrogen fertilizer 2: 750 grams of nitrogen fertilizer per tree 3...

BACKGROUND Numerous studies have evaluated protein and amino acid levels in human milk. However, research in this area has been limited by small sample sizes and study populations with little ethnic or racial diversity. OBJECTIVE Evaluate the protein and amino acid composition of mature (≥30 days) human milk samples collected from a large, multinational study using highly standardized methods...

1.1 Biological nitrogen fixation and nitrogen nutrition in soybean plants Biological nitrogen fixation is one of the most important processes for ecosystem to access available N for all living organisms. Although N2 consists 78% of atmosphere, but the triple bond between two N atoms is very stable, and only a few group of prokaryotes can fix N2 to ammonia by the enzyme nitrogenase. Annual rate ...

     For investigation deficit irrigation and nitrogen application effect on nutrients uptake of henna ecotypes, this research was conducted in the form of split-split-plot on the basis of randomized complete block design with four replications in the Research Field of Islamic Azad University, Jiroft, Iran in 2013-2014. The main, sub and sub-sub plot were deficit irrigation (100, 75 and 50% of ...

an experiment was conducted to evaluate the effects of dietary crude protein (cp) and lysine levels on performance and nitrogen excretion in broiler chickens. four hundred twenty 7-day old chickens from ross 308 strain were randomly allotted to 6 dietary treatments with 5 replicates of 14 chicks each (7 male and 7 female chicks). the cp levels were 17, 18, and 20 percent and lysine levels were ...

the objectives were to investigate the effects of addition of alfalfa hay as an absorbent on fermentationquality and effluent production of corn silage. three levels of corn forage with dry matter (dm) contentsof 18.3, 21.7 and 25.5 percent were supplemented with 0, 5, 10, and 20 percent alfalfa hay, on as fedbasis, and ensiled in three replicates in polyvinyl chloride mini-silos in a completel...

one hundred twenty male broiler chickens of 20 d of age were used to study the effect of enzyme supplementation on the apparent metabolisable energy corrected for nitrogen in corn, wheat and triticale using total excreta collection or marker methods. the average apparent metabolisable energy corrected for nitrogen in corn, wheat and triticale on dry matter basis, were 3480 ±90, 3263 ±61 and 326...

abstract in order to evaluate the effect of different nitrogen application methods on yield and yield components of winter wheat, a field experiment with split plot arrangement in completely randomized blocks design with four replicates was conducted in 2006. basal dressing in three levels (1- with no basal dressing, 2- strip and 3- distributing nitrogen fertilizer) as main plot and top dressin...

in order to evaluate efficiency of nitrogen fertilizers consumption in a sugar beet monogerm hybrid variety of zarghan, a field experiment was conducted in a loamy soil during 2007 in the research farm of sugar beet seed institute located in karaj. five levels of nitrogen fertilizers including 0 (check), 120, 160, 200 and 240 kg/ha of net nitrogen from urea fertilizer (46 percent of pure nitrog...

The fuel properties of wood can be summarized by ultimate and proximate analysis and determination of the high heating value. It is not valid to list these values for species since a species has not been adequately sampled and tested. Enough is known, however, to say that softwoods have a high heating value of about 9,000 Btu per pound; whereas hardwoods have a value of about 8,600 Btu per poun...
