Abstract

Kaylan productions in Indonesia is still low. Production of Kaylan can be increased with nitrogen fertilizer using from vermicompost and urea fertilizer combination. The objectives of this experiment was to find the best nitrogen fertilizer dose by giving vermicompost combination and urea fertilizer as source of nitrogen  to increase production and quality of Kaylan. The experiment was conducted from March until May 2015 in green house at the Technical Implementation Unit of Agriculture Experimental  Garden, Riau University. The experiment using Completed Block Design with 7 treatment and 3 replication. The treatments as follow: A = 0 kg N/ha, B = 150 kg N/ha (120 kg N/ha from kascing and 30 kg N/ha from urea or 4:1), C = 150 kg N/ha (112,5 kg N/ha from kascing and 37,5 kg N/ha from urea or 3:1), D = 100 kg N/ha (80 kg N/ha from kascing and 20 kg N/ha from urea or 4:1), E = 100 kg N/ha (75 kg N/ha from kascing and 25 kg N/ha from urea or 3:1), F = 50 kg N/ha (40 kg N/ha from kascing and 10 kg N/ha from urea or 4:1) and G = 50 kg N/ha (37,5 kg N/ha from kascing and 12,5 kg N/ha from urea or 3:1). Obtained data then anlyzed by variant analysis or F Test and conducted by DNMRT on 5% level. Parameters observed high of plant, leaves total, leaves length, leaves wide and wet weight. The experimental result show that the were significant for  high of plant, leaves length and leaves wide. The best dose of nitrogen fertilizer is treatment B =150 kg N/ha (120 kg N/ha dari kascing dan 30 kg N/ha dari urea atau 4:1).
