Abstract:
This study aimed to obtain the interaction of Trichoderma sp and compound fertilizers, and to determine the effect of Trichoderma sp and compound fertilizer in cacao seedlings (Theobroma cacao L). The research was carried out for 4 months starting from January to April 2013. The research was conducted at the experimental farm of the Faculty of Agriculture, University of Riau Jl. Bina Widya Baru Desa Simpang Kecamatan Tampan, Pekanbaru. Method using a completely randomized design (CRD) with factorial treatment. The first factor: Trichoderma sp. (T) consists of 4 levels that is without Trichoderma sp (T0), Trichoderma sp 25 g/polybag (T1); Trichoderma sp 50 g/polybag (T2) and 75 g/polybag (T3). The second factor: without compound fertilizer (M0), compound fertilizer 1 g/polybag (M1), compound fertilizer 2 g/polybag (M2); compound fertilizer 3 g/polybag (M3). Data were analyzed using ANOVA and continued with further DNMRT test at the 5% level. The parameters measured is high seed (cm), stem diameter (mm), number of leaves (pieces), and leaf area (cm2). The results showed that the interaction of Trichoderma sp give a dose of 75 g/polybag and compound fertilizer dose of 2 g/polybag well give more influence to the parameters plant height and stem diameter. Giving Trichoderma sp no real effect on all treatments. Compound fertilizers dose of 2 g/polybag gives a better effect on parameter plant height, stem diameter and number of leaves.
