Effectiveness of Manganese (Mn) on Growth, Production and Chlorophyll Content of Mustard Greens (Brasica rapa L.) With Wick System Hydroponic

Abstract

This study aims to find out the effectiveness of manganese fertilizer (Mn) on the growth, production and chlorophyll content of mustard pakcoy plants with wicksyhydroponic stem. This study uses a randomized group design (RAK) single factor, namely the dose of Manganese fertilizer with 4 repeats so as to produce 16 units consisting of 4 levels, namely tanpa pupuk Mn; concentration 50 ppm; 100 ppm; and 150 ppm. The observation variable consists of plant height, stem diameter, wet weight, dry weight and chlorophyll content. Dianalis data using variant analysis (ANOVA) then continued with the tukey range test at the level of 5%. The results showed a noticeable response to observations of plant height at ages 14, 28 and 35 hst and stem diameters at ages 21 and 35 hst. The provision of Mn fertilizer is also able to increase the chlorophyll content of pakcoy plants by 29.18%, chlorophyll b by 20.29% and total chlorophyll by 21.68%.
