Plant nutrition management is an important factor in the success of cultivation of medicinal plants, which leads to the improvement of their quantitative and qualitative yield. Therefore an experiment was conducted as a randomized complete block design with three replications and 8 nutritional treatments during three growing seasons on Satureja. spicigera Jamzad.The treatments were different le...

In order to study effect of plant density on yield and seed yield components of forage vetch in rain-fed and supplemental irrigation conditions, two separate experiments were conducted at the research filed of faculty of agriculture, Lorestsn University, during 2008-2009. Three species of forage vetch (Vicia narbonensis, V. sativa and V. dasycarpa) and in three plant densities (100, 150 and 20...

In order to evaluate the effect of concentration and time of foliar spraying of nitrogen fertilizer as supplemenfary to soil nutrition on grain yield and some important traits of rapeseed (Hyola401), an experiment was conducted in complete randomized block design with 16 treatments and three replications in in 2008-2009, 2009-2010 growing seasons, and in 2003-2005 growing seasons in paddy field...

A study was conducted in 2007 to investigate the effect of nitrogen fertilizer rates (0, 30, 60 Kg ha-1) on some agronomic characteristics, seed yield and oil percentage in three Sesame(Sesamum indicum L.) cultivars (Dashtestan, Darab 14, and Zarghan) in Kaki region (Bushehr Province). The type of design was completely randomized block with factorial arrangement and three replications. Nitrogen...

  In order to study the effects of different levels of irrigation, nitrogen and plant population on yield, yield components and reserved dry matter remobilization of seed corn (SC. 704 hybrid) a research was conducted at the experimental field in Khuzestan Natural Resources and Agricultural Science University in summer, 2004. This research was made based on three split-plot field experiments, R...

In order to optimized nitrogen fertilizer recommendation for a new safflower cultivar called “Padideh” an experiment was conducted in two regions of East Azerbaijan, Tikmehdash and Shabestar. Experimental design was a randomized complete blocks design arranged in factorial with three replications. The first factor was different nitrogen rates including 30, 60, 120 and 180 kg ha-1 nitrogen suppl...
