Understanding the nitrogen remobilization by plant, in order to obtain cultivars with higher quality, has specific importance in plant physiology. In this experiment, a bread and a durum wheat cultivar, were treated with different rates and times of nitrogen application, by using split factorial on the basis of randomized complete block design with three replications at Shiraz region during 200...
individual grain weight of wheat kernels differs with their positions on a spike. cultivation practices (such as fertilizer nitrogen and plant growth regulators application) can be used to improve weight of basal and distal kernels. for this purpose, two experiments based on randomized complete block design were carried out with three replications. the aim of this research was to study the mech...
To investigate the effect of nitrogen and zinc elements on the quantity and quality characters of sunflower plants (Jamah1cultivar), a factorial experiment in a randomized complete block design with three replications was conducted at the University of Zabol, Zabol, Iran in 2013. The experiment consisted of three nitrogen levels: 100, 200 and 300 kg ha-1 as the first factor and three levels of ...
dianchi lake is one of the most three seriously eutrophic lakes in china. in the present study, the phosphorus (p) and nitrogen (n) fractions in 37 surface sediments samples collected in the dianchi lake were investigated. the total phophorus (tp) in sediments was divided into two parts: inorganic p (ip) and residual p (res-p). the results showed that the total phosphorus content in surface sed...
We determined phosphate uptake by calcareous sediments at two locations within a shallow lagoon in Bermuda that varied in trophic status, with one site being mesotrophic and the other being more eutrophic. Phosphate adsorption over a six hour period was significantly faster in sediments from the mesotrophic site. Uptake at both sites was significantly less than that reported for a similar exper...
This paper reports the results of a 2-year study of water quality in the River Enborne, a rural river in lowland England. Concentrations of nitrogen and phosphorus species and other chemical determinands were monitored both at high-frequency (hourly), using automated in situ instrumentation, and by manual weekly sampling and laboratory analysis. The catchment land use is largely agricultural, w...
In order to investigate the effect of sugar plant effluent on shoot solute percentage, yield components and grain yield of two wheat cultivars, a two year field experiment was conducted on a farm near Eghlid sugar plant during 2004-2005. Treatments consisted of two wheat cultivars (Alamot and Zarin) and two irrigated treatment: irrigation with effluent and irrigation with spring water (control)...
this experiment was laid out in order to evaluate the effects of different biofertilizers on yield components of barley. the experiment was a factorial design with three replications. treatments were three nitrogen biofrtilizers (nitroksin, nitrokara and supernitroplass) and three phosphate biofrtilizers (phosphate barvar2, biozarr and superplass) with control for them and yield components we...
Background: Various chemical, physical and biologic treatment methods are being used to remove nitrogen and phosphorus from wastewater. Sequencing batch reactor (SBR) is a modified activated sludge process that removes phosphorus and organic material from sanitary wastewater, biologically. Methods: This study was conducted in 2016.The performance of an aerobic-anaerobic SBR pilot device, locat...
