Abstract

In order to investigate the effects of different levels of nitrogen and phosphorous fertilizers on flower yield , yield components and some quality components of German chamomile, a factorial experiment based on a randomized complete block design with four replications was carried out in the Medicinal Plant Research Farm of Shirvan College of Agriculture during growing season of 2007-2008. Nitrogen had three levels (0, 100, 200 kg/ha urea) and phosphorous also had three levels including 0, 30, 60 kg.ha-1 triple super phosphate. The results showed that application of nitrogen and phosphorous fertilizers imposed a significant effects (p < 0.01) on plant height, number of branches per plant, number of flower per plant and flower yield. Plants treated with 200 kgha-1 urea had the highest flower yield (1423 kg.ha). Among phosphorous levels, plant treated with 60 kgha-1 triple super phosphate produced the highest flower yield (1309 kgha-1). Fertilizers had no effect the percentage of chamazulene. However, plant treated with 200 kgha-1 urea and 60 kgha-1 triple super phosphate fertilizers produced the highest essential oil and chamazulene per square meter due to higher flower yield.
