Abstract

For finding out the effect of nitrogen and calcium carbonate fertilizers on nitrate and nitrogen accumulation in aboveground biomass, calcium concentration and dry weight of leaves of satureja hortensis L., a factorial experiment was carried out based on randomized complete block design with three replications in Karaj in 2008. The nitrogen fertilizer was in four levels (0, 50, 100 and 150 Kg. ha-1) and calcium carbonate (lime) fertilizer in three levels (0, 5 and 10 t. ha-1). Total nitrogen and leaves nitrate, calcium concentration and leaves and shoot dry weight were measured. The results showed that calcium carbonate had significant effects on nitrogen (p
