production of onion all thruough the year particularly in semi tropical regions has been considered as an alternative to fulfil the local markets needs. in order to determine the best amount and method of urea fertilizer application so that to have higher yeild and lower amount of nitrate content the effects of seven levels of urea fertilizer including 0, 90, 180, 270, 360, 450 and 540 kg of ni...
in order to study the effect of different levels of nitrogen and sulfur fertilizers on yield, yield components, content of some elements, qualitative and quantitative traits of spring safflower (serin cv.) an experiment was conducted at agriculture and natural resource research station of ardabil in 2008. this experiment was carried out in factorial experiment in completely randomized block des...
The aim of this study was to investigate the effect of chemical fertilizers of nitrogen, phosphorus, sulfur and biofertilizer on some growth indicators of Camelina sativa L. experimental plant during the crop year 2016 in a farm located in Kazerun and as a factorial in the form of complete randomized block design with three replications. Treatments include fertile biofertilizer 2 containing pho...
in order to study the effect of organic fertilizers application on increasing nitrogen efficiency and also quantitative and qualitative characteristics of sugar beet, a series of experiments were performed for two years (2008 and 2009) using three amino acid containing organic fertilizers at motahari research station of sugar beet seed institute (sbsi), karaj, iran. four rates of organic fertil...
This paper presents for the first time the results of a full life cycle assessment (LCA)1 study for the three most common types of house in the UK: detached, semi-detached and terraced. All life cycle stages are considered, including house construction, use and demolition after 50 years. The results indicate that the use stage has the largest contribution to most environmental impacts. For exam...
in order to evaluate the effects of beneficial free living bacteria (azotobacter chroococcum and azospirillum brasilense) compared to different nitrogen fertilizer levels on yield and yield components of barley (hordeum vulgare cv reyhan) a field experiment was conducted at research station college of agriculture, ferdowsi university of mashhad in 2007-2008. the experiment was arranged in a ran...
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
Rapeseed needs a sufficient amount of nitrogen for optimal seed yield, but the efficiency of this plant in using nitrogenous (N) fertilizers is low, which causes an increase in N consumption in the cultivation of this plant. The need to maintain a high grain yield necessitates the use of a suitable timely program and manage the consumption of N fertilizers. Thus, a field experiment was conducte...
A two-year study (2007-2008) was carried out to explore the effect of split application of nitrogen fertilizer on yield, dry matter and harvest index of Marfona potato cultivar in Isfahan Agricultural Research Center, Iran. A randomized complete block design with a split plot arrangement with three replications was used. The main plots were three levels of nitrogen (100, 200 and 300 kg ha-1) an...
To better understand the effects of tillage practice and fertilization management on greenhouse gas emissions yields, a four-year field experiment was conducted to assess practices (rotary (RT) no (NT)) methane (CH4) nitrous oxide (N2O) rice yield under four strategies (no fertilizer without straw (CK), inorganic (F), fertilize with biochar (FB), (FS)). The results showed that NT significantly ...
