effect of salicylic acid and mineral nutrition on fruit yield and yield components of coriander (coriandrum sativum l.)

in order to study the effect of mineral nutrient and salicylic acid on the fruit yield and yield components of coriander, a study was conducted in experimental field of gorgan university during 2007. the experiment was laid out in randomized block design with ten treatments (salicylic acid, nitrogen, phosphorus, potassium, magnesium, zinc, iron, boron, molybdenum and control) in three replications. the results showed that among the all evaluated traits, only 1000 seed weight did not respond significantly to treatments. in this case, effect of phosphorus, zinc, potassium, nitrogen and molybdenum on yield, and effect of nitrogen, zinc, potassium and phosphorus on biomass “was significant than was significantly greater than control”. plant height and number of branch per plant was enhanced significantly by nitrogen, phosphorus, potassium, molybdenum and zinc. all treatments, except salicylic acid, increased number of umbel per plant significantly, and the number of umbel per plant had highest correlation with fruit yield.
