<![CDATA[The purpose of the study is to analyze the influence of CaCl2 concentration and cultivation technique on the quality of Cosmos caudatus. This research was conducted from February to April 2021 in the field laboratory UNISMA at Merjosari, Malang and Central Laboratory of Agriculture Faculty UNISMA. This research was conducted using a Factorial Randomized Block Design with two factors. The first factor was CaCl2 foliar spray consisted of 3 levels (0%; 2.5% and 5% concentration). The second factor was cultivation technique, which consisted of 3 levels (organic, anorganic, and minimal tillage). Each combination was replicated 3 times with 4 samples. The variables analyzed were total soluble solid of leaf, Leaf ascorbic acid, leaf moisture content, and weight reduction percentage during storage time. The result indicated that CaCl2 concentration and cultivation model had no interaction that affected caudatus quality. CaCl2 foliar spray significantly affected the moisture and chlorophyll content of caudatus leaf, and the application of 5% CaCl2 gave the highest total chlorophyll content on 5 and 6 weeks after planting (71.53 µg/cm2 and 83.92 µg/cm2), meanwhile organic systems produced caudatus leaves with the highest vitamin C content (41.07 mg)]]>
