In order to evaluate the interaction effects of nitrogen and organic matter on growth and yield of dryland wheat, an experiment was conducted at the research station of the College of Agriculture, Shiraz University at Bajgah in 2005 and 2006. The experimental design was split plot in which three levels of nitrogen (0, 40, and 80 kg N ha -1) were main factors and additive organic matters includi...

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 study the effects of foliar application of phosphorus (P) and water deficit on yield and yield components of winter wheat (Triticum aestivum L., cv. Alvand), a split-plot experiment, with completely randomized blocks design and three replications, was carried out at the Research Farm of Boyer Ahmad Agricultural and Natural Resources Research Station, 13 km west of Yasouj, in 2008-20...

The effect of N levels and planting densities on quantitative and qualitative characteristics of grain yield in grain sorghum (cv. Kimia) was studied in summer 1998 at Kushkak Agricultural Research Station, Shiraz University. The experiment was a spilt plot with 4 replications in which 4 levels of planting densities (7.7, 10, 15.4, 20 seeds m-2) were applied as main plots and 4 levels of N (0, ...

German Chamomile (Matricaria recutita L.) is an annual plant from the compositeae family. Effects of three levels of urea (0, 40, 80 Kg.ha-1) and triple super phosphate (0, 30, 60 [Kg.ha-1) on the yield and essential oil production of chamomile was investigated. The experiment was a factorial on the basis of randomized complete block design with three replications conducted at Shaded University...
