Abstract
Abstract
Savory is one of the most important vegetables with high medicinal values whose growth is influenced by environmental factors including mineral nutrition. This study was done based on completely randomized design with 4 replications, under greenhouse conditions in order to evaluate the effect of organic and biological fertilizers on some morphologic and physiologic traits in savory during 2013. Treatments were control (without fertilizer application), NPK fertilizer, Vermicompost at 20 and 40 % of pot volume, manure at 20 and 40 % of pot volume, and phosphate biofertilizer (Barvar 2). The results showed that plant height, leaf area, number of leaves, fresh weight, stem diameter, P and N concentration in shoots were significantly influenced by treatments, but shoot dry weight and K concentration were not affected. The highest plant height, leaf number, leaf area, fresh and dry weight and N concentration were obtained in vermicompost 20% treatment. The highest stem diameter was in manure 20% treatment, while the highest chlorophyll index and P concentration were obtained in biophosphate and 20% vermicompost treatments.
