Experiments conducted by the authors and their colleagues in the previous five years are summarized. It is concluded that dietary requirements for rumen-degradable, nitrogen (RDN) can be supplied entirely as nonprotein nitrogen (NPN): Also, that supplements of 'NPN and proteins are equally effective in stimulating forage intake, when intake of RDN in the forage is low, provided that intake of N...

the experiment was aimed at investigating the effects of defoliation (i. e. amanipulation of source size) at different times and with different intensities on yield, grain protein content and remobilization of dry matter from shoot to grain under various levels of soil moisture and nitrogen in winter wheat. two separate field experiments were conducted simultaneously under water stress vs irrig...

in order to study the effect of nitrogen level on physiological characteristics, grain yield and yield components of tetraploid wheat genotypes, a split plot randomized complete block design field experiment with three replications was conducted in 2007 at research farm of isfahan university of technology. four levels of nitrogen fertilizer (20, 80, 140 and 200 kg/ha) were chosen as main plots ...

Seed composition in soybean [Glycine max (L) Merr.] has not been well investigated under charcoal rot infestation under irrigated and non-irrigated conditions. The objective of the present experiment was to assess seed composition and nitrogen fixation under these conditions. No significant differences in protein levels in the moderately resistant germplasm line DT97-4290 were observed under th...

THE saline extract obtained in the preparation of globulins and albumins from pulses contains a non-protein nitrogenous fraction, which is dialysable, not coagulated by heat and not precipitated by saturation with salts or even by reagents such as trichloroacetic acid. Work on foodstuffs relates chiefly to the predominant protein characterising the seed and in the case of pulses the well define...

The aim of this study was to investigate the effects of starters and storage temperature (4 ºC, 25 ºC) onmicrobiological and physicochemical properties, volatile compounds and sensory evaluation of kefir.Kefirs produced by KFA and Chr. Hansen starters were stored at 4 ºC and 25 ºC for 40 days. pH andacidity at 4 ºC did not change (p ≥ 0.05), while at 25 ºC pH and total solid decreased as well a...

a field experiment was conducted in order to study the effect of nitrogen fertilizer and plant density on yield and quality of maize (zea mays l.) cultivar, mv500 silage as second crop. this study was conducted in agricultural research station of kurdistan university during 2012 growing season. the experiment was laid out as split plot based on randomized complete block design with three replic...

1. We have confirmed the results of previous workers on tetrachlorphthalein, fibrinogen, and lipase. 2. The total non-protein nitrogen, urea, and amino-acids of the blood serum show a definite and sometimes marked increase in phosphorus poisoning. These changes are not so evident in chloroform poisoning, although they sometimes occur. They are usually terminal phenomena. 3. The urinary nitrogen...

in order to investigate the effects of different levels of nitrogen rate on yield and seed yield components of wheat cultivars, an experiment was conducted on araghi mahalleh (gorogan) research farm in 2008. treatments, nitrogen in the form of urea (0, 90, 180 and 270 kg/ha) and cultivars (tajan, falat and n81-18) were arranged as factorial based on randomized complete block design with four re...
