The effects of (i) herbage allowance, (ii) frequency of allocation and (iii) grass silage feed value on ewe and lamb performance were studied in mid-gestation ewes. Furthermore, the effects of (i) herbage allowance, (ii) frequency of allocation and (iii) grazing date and their interactions on subsequent herbage yield and feed value were also evaluated. Swards, which had a cut of silage removed ...

sclerotinia stem rot (ssr), caused by sclerotinia sclerotiorum, is the most important diseases of canola (brassica napus) in iran. in order to study of the impact of ssr on canola yield, infection situation and yield of 80 fields in four different regions of golestan province (gorgan, ali abad, kalaleh and gonbad) in north of iran, was recorded during two growing seasons (2006 and 2007). ssr se...

In order to determine the responses of morphological characteristics, yield and yield components of rapeseed (Brassica napus L.) to plant density and weed interference duration, a factorial experiment was conducted using a randomized complete block design with 3 replications at the Rice Research Institute of Iran (RRII) in Rasht, in the 2008 growing season. The factors comprised plant density a...

in order to evaluate of diversity among new maize hybrids for quantitative and morphological traits, 17 new single cross maize hybrids were studied in shahrood agriculture research station using randomized complete blocks design with four replications. results showed that five independent factors were responsible for significant correlation between 16 measured traits and explained 89.18% of tot...

BACKGROUND The robustness of Saccharomyces cerevisiae in facilitating industrial-scale production of ethanol extends its utilization as a platform to synthesize other metabolites. Metabolic engineering strategies, typically via pathway overexpression and deletion, continue to play a key role for optimizing the conversion efficiency of substrates into the desired products. However, chemical prod...
