effect of different irrigation regimes and nitrogen fertilizer on percentage of grain fatty acids, yield, water and nitrogen use efficiency of pumpkin was studies as split plot based on complete randomized block design with three replications in growing season of 2013. irrigation treatments (320, 420, 600 and 900 mm ha-1) were se as main plots and nitrogen fertilizer (0, 130, 260, 390 and 520 k...
Modeling plant response to salinity and nitrogen deficiency is very important for estimating optimum yield in arid and semi-arid regions. For this purpose, the models of Leibig-Sprengel (LS) and Mitscherlich-Baule (MB) originally proposed to explain plant response to nutrients only were modified to evaluate plant yield response to combined nitrogen and salinity stress conditions. Afterwards, in...
Understanding the nitrogen remobilization by plant, in order to obtain cultivars with higher quality, has specific importance in plant physiology. In this experiment, a bread and a durum wheat cultivar, were treated with different rates and times of nitrogen application, by using split factorial on the basis of randomized complete block design with three replications at Shiraz region during 200...
to study the effects of simultaneous application of urea, znso4 and inoculants, (azotobacter and azospirillum), on uptake and nitrogen use efficiency in rapeseed, var. hyola308, a field experiment with split plot factorial layout based on a randomized complete block design was conducted at the research field of faculty of agricultural science, university of guilan in 2008. experimental treatmen...

The experimental was split plot in a randomized complete block design with three replications. In this experiment, different levels of nitrogen in the main plots included four levels (0, 50, 100 and 150 N) kg.ha-1 urea and wheat varieties, including cultivars, Sepahan and SW were placed in the subplots. Results showed that nitrogen fertilizer and cultivar were significant effects on ...
This study was designed and implemented to investigate the yield and agronomic characteristics in three differently maturing corn (Zea mays L.) hybrids (SC704, SC500, and SC260) using four nitrogen (N) levels (0, 80, 160, and 240 kg N ha-1, from Urea, N= 45%). The experiments were conducted in Zabol (South-West of Iran) and Isfahan (Central Iran) in 2014 and 2015, respectively, using a split-pl...
Nitrogen components of yoghurt milk samples and resulting probiotic set yoghurt weredetermined. Analyses included total nitrogen (TN), non-casein nitrogen (NCN), non-proteinnitrogen (NPN), casein nitrogen (CN) and proteolysis index (PI). Yoghurt samples wereanalyzed 1, 7, 14 and 21days after production and storage at 5±1°C. TN, CN and PI contentsof yoghurt milk samples with high Somatic Cell SC...
