to investigate the effect of deficit irrigation on quantitative and qualitative yield of soybean cultivars, an experiment was conducted as split plots based on randomized complete block design with three replications at agricultural research farm, university of guilan, during 2009. main factors were included four irrigation levels based on potential moisture 30-35 (i1), 50-55 (i2), 70-75 (i3) c...

A study was conducted to investigate the effect of different planting densities and nitrogen doses on essential oil content and yield in herb and leaves of basil (Ocimum basilicum L.). The research was conducted during 2007 and 2008 using split-plot randomized complete block design with four replications. The experiment consisted of four plant densities (30×20, 40×20 and 50×20 cm) as the main p...

Background & Aim: Ziziphora L. genus belongs to the Lamiaceae family, which has important medicinal and aromatic plant species. In current study, essential oil chemical compositions of two Ziziphora L. species (Z. tenuior L. and Z. clinopodioides Lam.) were investigated. Experimental: The flowering branches of Z. tenuior and Z. clinopodioides</e...

in order to evaluate the effects of drought stress and methanol foliar application on some quantitative and qualitative traits of soybean (cv. viliamz), a split plot experiment was conducted based on randomized complete block design at the faculty of moghan research farm in 2011. treatments were three levels of drought stress based on irrigation at depletion of 40, 55 and 70 percent of availabl...

A pot experiment was conducted to determine the effect of compost and bio-fertilizers on the growth, yield and oil constituents of marjoram (Majorana hortensis L.). Forty five days old seedling were transplanted in soil treated with 15 and 30% aqueous extracts of compost and/or biofertilizers (mixture of Azospirillum brasilienses, Azotobacter chroococcum, Bacillus polymyxa & B. circulans) in ad...

The limited availability of fossil fuels has encouraged the need of replacement fuels of renewable nature. Among the renewable fuels, biodiesel produced from oil seeds and food wastes has been favored by the majority of researchers. In this study, Tectona Grandis seed oil has been investigated as a non-edible feedstock for biodiesel. The oil content of seed is 43% which makes it suitable for co...

in order to study the effects of intra and inter-row spaces and planting pattern on the yield components, seed and oil yield of pumpkin (cucurbita pepo l.), a field experiment was conducted as split-split plot based on randomized block design with three replications during 2009-2010 at the agricultural research station of ferdowsi university of mashhad, iran. two levels of inter-row space (1 an...

this study carried out to determine the differences between oil content and fatty acid compositions of 12 exotic and 6 local safflower genotypes. the experiments were arranged in randomized complete blocks design with three replications in research station of ferdowsi university of mashhad. the results of variance analysis showed that the differences of seed yield, oil content and fatty acid co...
