Use of enhanced-efficiency N fertilizers (EENFs) in row crop agriculture has not been well studied despite increasing interest in these N sources to increase crop yield while decreasing N loss. A field study was conducted in Central Alabama from 2009 to 2011 to compare EENFs to standard N sources in a high-residue conservation cotton production system. Nitrogen fertilizers evaluated were: urea;...

A study was conducted at Bunda College during the 2003/04 crop season to assess the effect of fertilizer application practices on performance of maize with emphasis on improving the efficiency of using urea as a top dressing fertilizer The treatments were laid out as a split-plot in a randomized complete block design (RCBD) with maize varieties as main plots and fertilizer application practices...

in order to study the effect of different n fertilizer on berseem forage in an intercropping with basil, this experiment was conducted in research farm of college of agriculture, university of tehran during growing season 2011. experimental treatments were arranged as split plots based on a randomized complete block design with three replications. different fertilizers consisted of control (no ...

in order to study the effect of solitary and combined application of two types of green manure, cow manure, barvar-2 phosphate fertilizer and conventional chemical fertilizer on some of the qualitative and quantitativeproperties of sugar beet, an experiment was conducted at the research farm of shahrekord university in 2013. the experimental design was randomized in a complete block design with...

BACKGROUND: Fertilizer management plays an important role to achieve sustainable agriculture. OBJECTIVES: Current study was conducted to assess response of agrophysiological traits of wheat to apply different level of fertilizer and biologic fertilizer (Phosphorus and Nitrogen). METHODS: This research was carried out via factorial e...

in order to comparison the foliar application of biological, biostimulator and chemical fertilizers on growth characteristics and yield of saffron, a factorial experiment was conducted in a completely randomized block design with four replication in 3- year field of saffron in dargaz, khorasan razavi province from 2010 to 2011. the first factor had 5 levels included biostimulator fertilizer bio...

background: considering that elisa method presently is the test of choice for diagnosis of fasciolo­sis, the present study was undertaken to evaluate the maximum validity of coated plates at dif­ferent temperatures and different times during one year of evaluation. methods: serum samples of patients infected with fasciolosis (n=10), hydatidosis (n=5), toxocaria­sis (n=5), and negative control s...

a trial study was set to assess the influence of the plant residue management in conjuction with application of different nitrogen sources on accumulation and translocation of wheat stem reserves, at the agricultural faculty of shahid chamran university of ahvaz during 2011-2012. the experimental design was split plot at randomized completed block design arrangement. the main plot were differen...
