Abstract
Common Purslane (Portulaca oleracea) that is known more as a weed, but the World Health Organization has recognized it as the most widely used medicinal plants. Purslane what distinguishes plants from other omega-3 fatty acid synthesis in its leaves. To study the effects of irrigation and fertilizer regimes on quantitative and qualitative traits of Purslane, a plot test in a randomized complete block design with three replications during 2014, was conducted at the Institute of Agriculture, University of Zabol. The main factor was: 80% (no stress), 60% (mild stress) and 40% (severe) of available water, and treatments fertilizer in five levels: control (without fertilizer use), manure (20 tonnes ha-1), vermicompost (15 tonnes ha-1), urea (150 kg ha-1) and compound fertilizer NPK (10:10:10) was 100 (kg ha-1) subplots. Soil moisture measurement the growth period was Time Domain Reflectometry (TDR). The quantitative traits were: fresh weight of leaves and roots dry weight of leaves and root , seed weight, number of branches in plant, number of capsules in plant, chlorophyll a and b, proline and anthocyanin in leaf , seeds oil content, as well as composition and percent fatty acids in the leaves and seeds of Purslane using of Gas Chromatography "Gc" were determined. Results showed that the effect of irrigation regimes, fertilizer and their interaction on the measured properties with the exception of the fatty acid composition was significant. Most of the fresh and dry weight of leaves, fresh and dry weight of root, seed weight, number of branches in plant, number of capsules in plant and oil content of optimum irrigation (80% of available water), respectively. As the severity of the drought of the properties amounts were reduced. While proline and anthocyanins in leaves was increased along with the increase of water stress. A comparison of average effect of fertilizer treatment on the measured properties showed that the use of organic fertilizers in addition to making qualitative and quantitative performance rather than chemical fertilizers, could have an adverse effect on the properties of drought also amend measured. Also replace organic fertilizers instead of chemical fertilizers can be taken to reduce environmental pollution and sustainable agriculture.
