the effects of inoculation of thiobacillus and the type of nitrogen fertilization (urea and ammonium sulphate fertilizers) on yield and yield components of rapeseed cultivars (okapi, slm 046 and reagent * cobra) were studied. the experiment was carried out as spilit plot factorial in randomized complete block design with 4 replications in shahrood university of technology. reagent * cobra culti...

sowing date is an important determinant of yield in canola. cultivation of winter rapeseed cultivars in semi arid regions of iran however it has high potential for production, but, mentioned cultivars are late maturity and this late maturity cause to that silique formation and seed filling periods mature in the same time with hot and dry weather condition. in contrast, spring rapeseed cultivars...

This study was conducted at the Agricultural Research Station, King Abdulaziz University at Hada El-Sham during 2007 and 2008 seasons to improve the seed yield of sesame (Sesamum indicum L.) in the Makkah Region, Saudi Arabia. Split plot design with four replications was used in this study. Main plot treatments were four nitrogen rates (0, 100, 150 and 200 kg N/ha) and the sub plot treatments w...

Stress is known to alter a variety of biological processes, including behavior and reproduction. It is therefore important to understand the stress levels of animals in captivity, especially those for whom captive breeding is a priority, such as the okapi. Levels of stress hormones can be measured from samples collected noninvasively, such as urine or feces, which are preferable with nondomesti...

designing breeding programs for winter rapeseed (brassica napus l.) cultivars with improved seed and oil yields requires information about the genetic variability of traits. in this study, 28 winter rapeseed cultivars were evaluated for genetic variation and relationships between 11 agro-morphological characters during 2010 and 2011. cultivars and cultivar × year interaction showed significant ...

There are limited data on the DE and ME values and the digestibility of fiber in canola meal, rapeseed meal, and rapeseed expellers fed to pigs. This experiment was conducted to measure the apparent total tract digestibility (ATTD) of energy, ADF, and NDF and to calculate DE and ME values in canola meal, 00-rapeseed meal, and 00-rapeseed expellers fed to growing pigs. Twenty-three barrows (init...

a field experiment was conducted during 2003-4, 2004-5 cropping seasons evalute the effects of plant density on growth and yield of different rapeseed cultivars. the study was carried out at ramin agriculture and natural resources university (35 km from northeast of ahwaz). the experiment was in the form of split plots' based upon a complete randomized block design of four replications. ma...

The interaction between plants and microorganisms, which is the driving force behind the decontamination of petroleum hydrocarbon (PHC) contamination in phytoremediation technology, is poorly understood. Here, we aimed at characterizing the variations between plant compartments in the microbiome of two willow cultivars growing in contaminated soils. A field experiment was set-up at a former pet...

in order to investigate the effect of seed rate on seed yield and yield components of three rapeseed varieties, a split- plot experiment was conducted in randomized complete block design with four replicates during 2008-2009 at baykola agricultural research station, neka, mazandaran province. in this experiment four seed rates (5, 7, 9 and 11 kg.ha-1) as main plots, three rapeseed cultivars (hy...

The effects of two different harvest stages (full flowering and full podding) on forage yield and quality of ten forage rape (Brassica napus L. var. oleifera) and three turnip (Brassica rapa L. var. rapa) cultivars were evaluated under rainfed conditions in a Mediterranean type climate at Bursa, Turkey, during the 2002/2003 and 2003/2004 growing seasons. Plant height, branches per plant, leaf l...
