In order to investigate the effect of urea and Azocompost on economic yield, nitrogen use efficiency (NUE) and radiation use efficiency (RUE) of wild majoram, a factorial 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 k...

Using farmed common carp, we investigated the genetic background of the second year overwintering performance and its relation to the performance during the third growing season and at market size. The experimental stock was established by partial factorial design with a series of 4 factorial matings of 5 dams and 10 sires each. The families were reared communally and pedigree was re-constructe...

a two years (2006–2007 and 2007-2008) experiment was conducted at national salinity research center, yazd, to evaluate salt-tolerant genotypes of brassica napus, b. rapa and b. juncea. to screen genotypes in the first growing season, 58 genotypes were grown under two irrigation water salinity levels of 2 and 12 ds m-1 in an augmented randomized complete block design with six replicated checks. ...

in order to investigate the effect of different weed-free and weed-infested periods on the growth indices of black seed, a field experiment was conducted at the agricultural research station of ferdowsi university of mashhad, during 2009-2010 growing season. the experiment was laid out in randomized complete block design with 12 treatments and 3 replications. twelve experimental treatments cons...

in order to study effects of competitive weeds (sinapis arvensis, hordeum spp., secale montanum and agrostemma githago) on morphological traits, yield and harvest index of winter rapeseed (brassica napus l.) cultivars a factorial experiment was conducted in islamic azad university of tabriz, during 2007-2008. experimental factors were weeds controlling times included weeding in rosette (5-7 lea...

The vegetation cover and rangeland production are the most important factors to determine the proper planning system for effective utilization and management of rangelands. In this research, the effect of climatic factors (temperature and rainfall) were studied on vegetation cover and forage production of four species (Festuca ovina, Bromus tomentellus, Dactylis glomerata and Agropyron trichoph...

The potential of entomopathogenic nematodes in suppressing T. squalida population on cauliflower from transplanting to harvest was evaluated. Significant reductions in plant infestation percentage and population density (/m) were recorded throughout the plantation seasons, 2011 and 2012 before and after spraying the plants. The percent reduction in numbers/m was the highest in March for the tre...
