The effect of a hydroponic system on mint and rosemary potted plants

Abstract

In this project, one can find the effect of salinity on mint and rosemary in a hydroponic controlled system. To show these differences some lab tests were done, starting with the chlorophyll tests, Polyphenol tests on the mint and rosemary yield and roots and Heavy Metal Analysis on yield, roots and water used in the system. The experiments showed some interesting differences from one treatment to the other and some other differences between the different herbs. While growing the herbs some differences like size and rate of development were recorded as well and these were related to the experiment results as well. A curious thing that came out is that rosemary had a hard time to live in a hydroponic system and this is shown in the polyphenol results, the polyphenols where relatively high compared to mint another interesting think is that rosemary didn’t produce any roots during the growing , on the other hand chlorophyll results showed that mint was performing at its best especially in the Medium salinity treatment, this is visible because of the low mortality rate shown here and later in the results and discussion section. The Report title is ‘The Effect of a Hydroponic System on Mint and Rosemary potted plants’ and in this report I discussed some aspects of hydroponics regarding mint and rosemary that can be found further on in the report, these aspects are the Heavy metal Absorption and deposition from and in the plant, Chlorophyll content in the yield and polyphenols. After doing this report I may conclude that mint can grow better than Rosemary in hydroponics and the best water and fertiliser treatments will be between 450 - 310 x10μs Conductivity, 140 - 200 x10ppm Parts per Million and pH that varies from 5 to 6.5. More detailed results and discussion can be found later on in the report.
