Abstract

This study wasaimedtoproducePakcoy (Brassicarapa L.) withbettergrowthandproductionusingHydroponicsystembyapplyingcombinationofNutrients AB MixandPaitan (Tithoniadiversifolia (Hemsl.) A. Gray). The research has beenimplementedfrom November 2020 toDecember 2020 at a screenhouseofTechnicalImplementation Unit (UPT), FacultyofAgriculture, Universityof Riau. The researchwasconductedusing a completelyrandomizeddesign (CRD) consistingof 5 treatments. thetreatmentgivenwas a combinationof AB mix nutritionandfermented paitan. The treatments in this study were AB mix 10 ml.l-1   + POC 0 ml.l-1, AB mix 7,5 ml.l-1   + POC 50 ml.l-1, AB mix 5 ml.l-1   + POC 100 ml.l-1, AB mix 2,5 ml.l-1   + POC 150 ml.l-1, AB mix 0 ml.l-1   + POC 200 ml.l-1 andeachtreatmentwasrepeated 4 times. The observedvariablesconsistedofplantheight, leafwidth, numberofleaves, plantfreshweight, ediblefreshweightandroot volume.
