RESPON PERTUMBUHAN BIBIT KOPI ARABIKA(Coffea arabica L.) PADA PERLAKUAN BERBAGAI PUPUK ORGANIK CAIR (POC) MELALUI TANAH DAN DAUN

Abstract

Growth Response of Arabica Coffee Seeds (Coffea arabica L.) In the treatment of various liquid organic fertilizers (POC) through the soil and leaves. This study aims to determine the effect of the interaction of liquid organic fertilizer cow urine and lamtoro leaves on the growth of arabica coffee seedlings (Coffea arabica L.). This research was conducted in Parik Sabungan village, Siborongborong District, North Tapanuli, precisely on the campus land of Sisingamangaraja XII Tapanuli University UNITA, with an altitude of ± 1400m above sea level. This study used a factorial randomized group design (RAK) consisting of 2 factors with each factor consisting of 4 levels of treatment. Liquid organic fertilizer of cow urine is given through the soil consisting of 4 levels of treatment with the symbol U, namely: U0 = 0 cc / plant (as a control), U1 = 200 cc / plant, U2 = 400 cc / plant, U3 = 600 cc / plant. Lamtoro leaf liquid organic fertilizer is given through the leaves consisting of 4 levels of treatment with the symbol L, namely: L0 = 0 cc / plot (control), L1 = 100 c . If the treatment shows significant changes observed, proceed with DMRT follow-up tests at the level of 5%, 1% and regression tests using Excel Software. This test aims to see the difference in influence on each treatment factor and modifiers observed during the study.
