Abstract

Research entitled The Effect of Goat Manure and Fertilization Frequency NPK Mutiara 16:16:16 on the Growth of Cocoa Seedlings (Theobroma cacao L.) was carried out at the Experimental Garden of the Faculty of Agriculture, Islamic University of Riau, Jalan Kaharuddin Nasution, KM 11 No.113, Kelurahan Air Winter, Bukit Raya District, Pekanbaru City, for 4 months starting from December 2022 to March 2023. The research aims to determine the interaction effect and the main influence of goat manure and the frequency of NPK Mutiara 16:16:16 fertilization on the yield of cocoa seedlings. This research used a factorial Completely Randomized Design (CRD) consisting of 2 factors, namely the first factor, goat manure consisting of 4 treatment levels, namely 0, 100, 200, 300 g/plant. The second factor is the frequency of fertilization NPK Mutiara 16:16:16 consisting of 3 treatment levels 1, 3, 5 applications. The parameters observed were plant height, number of leaves, total leaf area, stem diameter, root volume and root crown ratio. The observation data was analyzed statistically and continued with the BNJ test at the 5% level. The results showed that the effect of the interaction between goat manure and the frequency of NPK Mutiara 16:16:16 was significantly different on plant height, number of leaves, total leaf area, stem diameter, root volume, root crown ratio except stem diameter. The best treatment is a combination of goat manure at a dose of 300 g/plant and a frequency of NPK Mutiara 16:16:16 at a dose of 15 g/polybag 5 times. The main effect of goat manure is significantly different on all observation parameters. The best treatment is goat manure 300 g/plant. The effect of NPK Mutiara 16:16:16 fertilization frequency was significant on all observation parameters. The best treatment is NPK Mutiara fertilization frequency 16:16:16 5 times.
