Abstract

Abstract
The residual effect of inorganic and organic fertilizers on growth and yield of plants is one of the important problems in nutrition. This study was conducted to determine the residual effect of different fertilizers on yield, yield components, physiological parameters and essential oil percentage of Matricaria chamomilla under drought stress. A split plot arrangement based on randomized completely block design (RCBD) with three replication was conducted in 2009, at the University of Zabol. Treatments included W1 (non stress), W2 (75% FC) and W3 (50% FC) as main plot and three types of residual’s fertilizers: F1 (non fertilizer), F2 (chemical fertilizer), F3 (manure fertilizer) and F4 (compost) as sub plot. Results showed that water stress at W3 treatment reduced dry flower yield. Low water stress increased essential oil percentage and the highest oil was obtained in W2. In this experiment, free proline and total soluble carbohydrate concentration were increased under water stress. The residual’s manure and compost enhanced flower yield, percentage and yield of essential oil of chamomile at the second year. At a glance, animal manure application and light water stress (75% FC) was recommended to obtain best quantitative and qualitative yield.
