Pre-harvest desiccation of rapeseed crop may allow a more timely harvest as well as increase the speed and harvest operation efficiency as a second crop after rice. An effective desiccant which could be used as a harvest-aid with no negative effects on rapeseed yield and quality would be advantageous for oil seed crop producers and may reduce yield losses with no interferential effects on rice ...

in order to evaluate the effects of different levels of potassium and nitrogen on nitrogen use efficiency (nue) and yield of rapeseed (hyola 401), a field experiment was conducted at rice research institute of iran (rasht) in a factorial experiment based on a complete randomized block design with 3 replications for two years (2008-2010). the first factor was pure potassium fertilizer in three l...

Background and aim: The genus Satureja L. (Lamiaceae) includes 12 species of annual and perennial herbaceous plant in Iran. Satureja species have economic and medicinal importance because of their high essential oil content. In addition, they are used as culinary herbs and in the food, perfume and cosmetic industries. The aim of this study was to inve...

Increasing the yield of oilseed crops is an important objective for biotechnologists. A number of individual genes involved in triacylglycerol metabolism have previously been reported to enhance the oil content of seeds when their expression is altered. However, it has yet to be established whether specific combinations of these genes can be used to achieve an additive effect and whether this l...

a study was conducted to investigate the genetic variance components and the combinig ability of sunflowers lines at the seed and plant improvement institute, karaj, iran in 2006. a total of 41 genotypes including 2 cms, 13 restorer and their 26 corresponding hybrids were evaluated in a line × tester approach. the analysis of variance indicated that significant differences existed among genotyp...

in order to study the effect of organic fertilizer on shoot yield and essential oil content of lavender, this experiment was conducted in the research institute of forest and rangelands, karaj, iran, in 2013-14. the treatment groups consisted of vermicompost (0, 5, 10 and 15 ton/ha) and cow manure (0, 10, 20 and 30 ton/ha). the experimental design was a factorial experiment based on randomized ...

effects of various fertilizers such as farmyard manure (fm), urea, and plant growth promoting rhizobacteria (pgpr, including the genera azotobacter and azospirillium) were checked on yield, fatty acids, protein, and oil contents of sunflower. a two-year field experiment was conducted in a semi-arid region in iran in 2007 and 2008. the experiment was a split plot in a randomized complete block d...

in order to evaluate the effects of different plant growth promoting rhizobacteria (pgpr) on yield and yield components of sesame, an experiment was conducted in the form of randomized complete block design with three replications at research station, faculty of agriculture, ferdowsi university of mashhad in year 2009. treatments were: 1) nitragin (containing of azotobacter sp., azospirillum sp...
