The appropriate planting pattern of safflower in summer planting might be different from the planting pattern suitable for spring planting, and this has not been determined under Isfahan environmental conditions. A field experiment was conducted in the summer of 2000 at the Agricultural Research Station, Isfahan University of Technology, using a randomized complete block design with a split plo...
To study the effect of cycocel, nitrogen and planting density on nitrogen (N) content, remobilization and use efficiency of Esfahan 14 safflower cultivar, a field experiment was carried out as a factorial split-plot based on randomized complete blocks design with three replications at Research Farm of College of Agriculture, Yasouj University, in summer of 2010. Main plots were the factorial ...
retarding the staling rate of baked goods is one of the most important issues which is of nutritional and economical importance. application of native plant and seed hydrocolloids and mucilages with medicinal and nutritional value is an economic solution to postpone the staling phenomenon. in this study the effect of different concentrations of basil seed mucilage (0, 0.25, 0.5, 0.75 and 1% w/w...
cultivation of annual medics is a way to increase producing of forage with a better quality, to increase the quantity of producing forage in low yield drylands, and to assisst establishing pasture. this study was conducted in order to investigate the adaptation and determination of quantitative and qualitative characteristics of three species of annual medics. the experimnet was conducted in a ...
Manure not only supplies many nutrients for crop production, but it is also a valuable source for increasing soil organic matter content and improving soil structure. To increase organic manure content as well as improve the wheat production adding plant residues and livestock to soil is necessary. The experiment was conducted in Shavoor Research Station to determine seed yield and soil physica...
Fertilizer amendments can impact weed populations in a variety of ways. This study evaluated the effects of 12 year-long applications of different fertilization systems on size and composition of the weed seed bank in a conventionally managed maize monoculture field. Fertilization systems included all factorial combinations of two dairy cattle slurry rates, three vegetable, fruit and garden was...
OBJECTIVES To investigate the protective effect of Herpetospermum pedunculosum (H. pedunculosum) seed oil against carbon tetrachloride (CCl4)-induced liver damage. METHODS This experimental study was conducted at the Northwest Institute of Plateau Biology, Chinese Academy of Sciences, and Yantai University, China from November 2012 to May 2013. The H. pedunculosum seed oil was extracted using...
In most of the legally protected areas in Mexico local inhabitants use natural resources, such as fire wood or cattle grazing. These frequent but low-intensity disturbances have consequences at various levels of the tropical ecosystems and strongly impact forest structure and its regeneration capacity. Despite their importance, the effects of these perturbations in many aspects of tropical fore...
in order to evaluation of seed production index in lambsquarters (chenopodium album), leaf appearance and yield of fennel (foeniculum vulgare) under inter-specific competition a factorial experiment was conducted in islamic azad university, tabriz branch, iran, during 2011-2012. treatments were weed densities of 0, 2, 4, 6 and 8 plants per meter row and its relative emergence times of simultane...
Pinus nigra and Robinia pseudoacacia are exotic trees used for afforestation in Hungary. Pinus nigrawas non-invasive, however R. pseudoacacia escaped from cultivation and invaded several vegetation types including pine plantations. It has recently been planned to cut P. nigra plantations and replace them by native tree stands, especially in nature reserves. The scattered presence of R. pseudoac...
