an experiment was conducted to study wheat grain protein increasing through foliar application of nitrogen afterflowering. the rcbd design was analysed with three replications and four n-treatments as foliar application as(n0=0, n1=4kg.ha-1 urea, n2=8kg.ha-1 urea, n3=4kg.ha-1 ammonium sulfate). results showed that seed proteincontent increased significantly by foliar application of nitrogen. da...

In order to investigate the effect of urea, Azocompost and cutting on growth characteristics of Oregano, a factorial split-plot experiment was conducted based on randomized complete block design with three replications at Yazd and Mashhad, Iran, during 2012-2013 growing season. Four urea levels and four Azocompost levels (to provide 0, 40, 80 and 120 kg N.ha-1 each) for Yazd location )0, 43.5, ...

to study the effects of urea foliar spray at different plant growth stages on grain yield and protein percentage of two dryland wheat varieties of sardari and azar 2, an experiment was conducted in east mangor agricultural station of mahabad in 2007– 2008. the experiment design was split plot based on randomized complete block design with three replications. treatments were 50 gr×10 m-2 n as ur...

Nitrogen is a crucial nutrient affecting plant growth and development and its addition to the soil (as chemical or organic form) influences plant growth characteristics. One experiment was conducted as a factorial based on RCBD with two Chrysanthemum cultivars (‘Fred’ and ‘Angel’( and two N-fertilizer sources [Urea (750 and 1500 g/ha and Nitroxin 7.5 and 15 L/ha] used as fertigation method besi...

urea is the most common form of nitrogen fertilizer used in sugar beet cultivation. urea has a high solubility and its losses are high and consequently its efficiency is low. it is supposed that urea solubility can be limited and its efficiency can be increased by using slow-release nitrogen fertilizers. by conducting an experiment in three important sugar beet cultivation areas of khorasan pro...

Urea forms a 1:1 solvate with N,N-dimethyl-acetamide (DMA) [systematic name: diamino-methanal-N,N-dimethyl-acetamide (1/1), C(4)H(9)NO·CH(4)N(2)O] with both mol-ecules positioned on a twofold axis, giving rise to rotational disorder of the DMA mol-ecule. The mol-ecules display a layered structure in which urea mol-ecules form hydrogen-bonded ribbons bounded by mol-ecules of solvent.
