Budding is a good method of propagation in the Persian walnut (Juglans regia L.)., However, success of budding is low due to higher root pressure as well as the presence of phenolic compounds in the xylem sap. This study was conducted to compare various budding methods and cut below budding union on two and three-year-old Persian walnut under field conditions. The experiment was conducted based...

sunflower has many dry forage yields and is richer than corn in inorganic matter, protein and calcium. therefore, use of this forage in livestock diets can be valuable for elimination of food poverty. in order to determine the best harvest stage for sunflower silage, an experiment was conducted in 2007-2008 at agricultural faculty of shahid chamran university of ahvaz. a randomized complete blo...
