Abstract

The experiment was conducted at IPB Experimental Station, Leuwikopo, Dramaga, Bogor, from November 2009 until February 2010 to study the effect of different  nitrogen+potassium rates and harvest intervals on protein and anthocyanin production of waterleaf shoot (Talinum triangulare (Jacq.) Willd). A randomized complete block design was used with three replications of two factors, which were  four N+K  dosages (50 kg urea + 50 kg ha-1 KCl, 50 kg urea + 100 kg ha-1 KCl, 100 kg urea + 50 kg ha-1 KCl, 100 kg urea + 100 kg ha-1 KCl) and three harvest intervals (30, 15, and 10 days).  The results showed that interaction of 100 kg urea + 100 kg ha-1 KCl and 15-day harvest interval produced the highest content (8.29 mg g-1 fresh weight) and production (4.72 g plant-1) of protein.  The interaction of N+K dosages and harvest intervals were not significant in affecting the anthocyanin content.  The highest production of anthocyanin was produced by single treatment of 100 kg urea + 100 kg ha-1 KCl (152.23 µmol plant-1) and 10 days harvest interval (165.47 µmol plant-1), respectively.  Leaf protein levels negatively correlated with anthocyanin content.   Keywords: anthocyanin, fertilizer, harvest interval, protein, Talinum triangulare
