Abstract

The research was conducted in farm experiment faculty of agriculture, the University of Medan Area. That is located on PBSI street, Medan Estate, PercutSei Tuan subdistrict, Deli Serdang regency with an altitude 12 m dpl, a flat topographic and a type of alluvial land, starting in November 2018 to January 2019. The research was done by using the method of random designs that the group 's group (RAK) are composed of two treatment factors, those are: 1) Mixed of baglog compostwith cows manure (notation B) consisting of 4 conditions, those are: Bo= cows manure 1kg/plot, Bi= Baglog compost 2,8 kg/plot + cows manure 1kg/plot. B2= (Baglog compost 3,2kg + cows manure 1kg/plot), B3= (Baglog compost 3,6 kg + cows manure 1kg/plot, and 2) Organic fertilizer, liquid waste of palm(notation K) consisting of 4 treatments, are Ko= without treatment, K1=liquid waste 50 ml/l/plants, K2=chemicals 75ml/l/plants, K3= liquid waste 100 ml/l/plants. Every treatment repeated as much as two times. The parameters in this study is focus on the diameter of steam (cm), flowering age (day), total of pods/plants (fruits), long pods/plants (cm), thick/ plants (g), and production/plot (kg). The conclusion of this study as follows: 1) giving the mixed Baglog compost with cows manure had no real effects to the diameter of steam, total pods per plants, long pods/plants, thick and plants, and productions/plot but it had real effects to flowering age. 2) giving thePOC liquid waste ofpalms had the real effects to the diameter of steam 5 MST ages, flowering age, total pods per plants, long pods per plants, thick per plants, and production. And 3) the combination both of factors had real effects to long pods per plants, and production per plot, but had no real effects to the others parameters.
