| To study the effects of water stress and type of fertilizer on osmotic properties, essential oil content in chamomile (Marticaia chamomilla) a field experiment was conducted- using a split plots design with three replications in Research Field Station, Zabol University, Zabol, Iran in 2008 . Water stress treatments included control as 90% of field capacity (W1), 70 % field capacity (W2) and 50 % field capacity (W3) assigned to the main plots and different types of fertilizers, including control or without any fertilizer (F1), chemical fertilizer (F2), manure: 25 t.ha-1 (F3) and urban waste compost (F4) randomized in sub plots. Results showed that in water stress of 50% field capacity, flower yield of chamomile decreased by 18.1% in comparison with control. However, the highest flower yield and flower yield components (biomass, plant height, number of main stem and number of flower.plant-1) were obtained from W1 and application of chemical fertilizer, but in W3 and F3 had the best effect on flower yield and its components in chamomile. The highest essential oil content and oil yield were obtained in W2. With increasing stress severity, carbohydrates and proline contents, in green leaf tissues of chamomile, increased. Chemical fertilizer was the most effective type of fertilizer. It is concluded that under sever water stress, manure fertilizer was the suitable type of fertilizer in chamomile production. |
