Abstract

Two separate experiments were conducted to evaluate the effects of some pre and post -harvest treatments on growth characteristics of Calendula officinalis. The first experiment as RCBD with three replication studied the effects of organic fertilizers as vermicompost, cow and poultry manure with control plus soil cover (plastic white and black). Organic manure application +mulch had positive effects on flower fresh weight. The greatest amount for chlorophyll b content was recorded in vermicompost + black plastic cover. In the second experiment, the effects of nutrition with organic manure +soil cover and post-harvest flower drying temperature (natural drying in shade condition and oven drying at 40 and 60 0C) as a factorial based on RCBD were evaluated. The highest methanolic extract amount and total anthocyanin content were recorded with vermicompost + black cover + natural drying. For essential oil content and carotenoids gross amount poultry manure + black cover and drying at 60 0C was the preferred treatments. The highest recorded data for total flavonoids was traced in vermicompot and cow manure with white cover at natural drying condition. For total phenolics content, cow manure + black cover at 40 0C used for drying was selected as the treatment of choice. Also, vermicompost+ black mulch and natural drying were nice treatment combinations for the highest total phenolics content. In total, all the treatment applied i.e. organic manures, soil covers and drying methods at varying levels and combinations had suitable effectiveness on the growth characteristics and phytochemicals content of Calendula officinalis.
