Abstract

<span><span lang="EN-MY">This study was conducted to determine the effect of compost and compost tea on growth and physiological parameters of <em>Lepidium</em></span></span><span><span><em><span lang="EN-MY"> sativum</span></em></span></span><span><span><span lang="EN-MY"> L.</span></span></span><span><span><span lang="EN-MY"> 30-day-old Cress plants treated with compost and compost tea were harvested and different growth and physiological parameters were measured. Compost tea application increased </span></span></span><span><span><span lang="EN-MY">RGR, SLA, ULR and RL_AGR. The contents of Chlorophyll a and Chlorophyll b in the plants significantly increased at the media supplemented with compost 25% and compost tea 75%. While total soluble sugars in leaves of the treated cress plants decreased total non-soluble sugars, proline and total protein contents increased with an increase in compost and compost tea contents in culture medium.</span></span></span><span><span><span lang="EN-MY">.</span></span></span><span><span><span lang="EN-MY">From among different measured macro elements, K was further observed as compost levels rose in the growing media </span></span></span><span><span><span lang="EN-MY">Finally, the highest contents of micro-elements were measured at medium supplemented with 75% compost and compost tea. </span></span></span>
