Abstract

In Indonesia, coffee as a mainstay plantation commodity is cultivated by the government, private and community plantations. By the growing of coffee commodity in world trade, it gives great hope for the economy of farmers in particular. The purpose of this study is to examine the response and initial growth dosage of three varieties of Robusta coffee at several optimum watering biogas in watering doses for the initial growth of Robusta coffee plants (Coffea canephora pierre ex froehner), the differences of examine in initial growth of three robusta coffee varieties (Coffea canephora pierre ex froehner). This research was a factorial experiment which was arranged using a randomized block design (RBD) divided plot three times. The factor I is variety (V) which consists of 3 levels namely V1 = BP 42, V2 = BP 358, V3 = BP 409. Factor II is the dose of biogas liquid waste (B) to be given to plants consisting of 5 levels, namely B0 = control, B1 = 150 ml, B2 = 200 ml, B3 = 250 ml, B4 = 350 ml. The observations were held on vegetative variables in a non-destructive manner, periodically at 10-day intervals for 2 (two) months. Variables observed included plant height (cm), stem diameter (cm), number of leaves, length and width of leaves (cm), and amount of chlorophyll (mg-l). The test used is the F test to determine the effect of the treatment given. Then proceed with BNJ at α = 5% level to find out the difference of each treatment. Correlation analysis to determine the relationship between observed variables. From the results of this study noted that there was no interaction between Robusta coffee varieties and application of biogas liquid waste fertilizer doses on all parameters observed, indicating that the three Robusta coffee varieties tested have the same response and genetic similarity so that each variety has the same response fertilization treatment that is not significantly different.
