A note on nitrogen fertilizer application timing

Using Insurance to Enhance Nitrogen Fertilizer Application Timing to Reduce Nitrogen Losses

Nitrogen applied before planting is more vulnerable to lobs to the environment than nitrogen applied during the gro~ving season, but the growing season application can increase the risk o f lower yields c;iused by adverse weather that prohibits farmers to cornplete N application. An expected utility framework is used to illustrate the potential econo~nic benefit of insurance for :I farmer to re...

influence of nitrogen fertilizer application techniques on

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 randomized completely blocks design with four replicates was conducted during 2006-07. basal dressing in three levels (with no basal dressing, strip and distributing nitrogen fertilizer) as main plot and top dressing in six le...

Effect of the timing of nitrogen fertilizer application on grain yield and quality of bread wheat (Triticum aestivum L.) cultivars under terminal drought stress conditions

To investigate the effect of  the timing of nitrogen fertilizer application on grain yield and quality of bread wheat cultivars under terminal drought stress conditions, two field experiments were conducted at Agricultural Research Station of Miandoab in West Azerbaijan, Iran, in 2013-2014 and 2014-2015 cropping seasons. Experimental treatments were arranged as split plot factorial in randomiz...

Aqueous And Gaseous Nitrogen Losses Induced By Fertilizer Application

Effect of Manure Application on Reduced Nitrogen Fertilizer Consumptionin Potato Cv.Agria

Objective: An experiment was performed in Ardabil (2012) to investigate the effects of manure consumption in different amounts on reducing nitrogen fertilizer consumption in potato cv. Agria. Methods: This research was conducted in factorial design based on randomized completely blocks design in three replication  in which two manure factors in three levels (control, 30 and 60 tons/h) and nitro...
