The effect of fertilizer to production of neera dwarf coconut

Abstract

This research was conducted at the Pandu Experimental Garden (KP) from April until June 2015, North Sulawesi. The research was conducted using a factorial randomized block design. The first factors were the kinds Dwarf coconut (A),Tebing Tinggi dwarf (GTT), Bali Yellow Dwarf (GKB), Nias Yellow Dwarf (GKN), Raja Dwarf (GRA), and Salak Dwarf (GSK). The second factors are the doses of fertilization (B), without fertilizer, urea 500 g + SP36 375 g + Potassium Chloride 750 g + Kieserite 100 g, urea 750 g + SP 36 562,5 g + Potassium Chloride 1125 g + Kieserite 150 g and organic fertilizer. Each experimental unit was replicated three times, so that total is sixty. Parameters observed are volume of neera, the number of bunches tapped and duration of tapping, brix, and rendement of neera. The results showed that among five Dwarf coconuts tested, coconut GTT, GKB, GKN, and GSK can be considered as a source of raw material for making sugar. The total of sap produced varies depending on the kinds of dwarf coconut and the dose of fertilizer.
