Abstract

This research was conducted in the Experimental Field, Faculty of Agriculture,Riau Islamic University from February to June 2009. The research aim to study theresponse of various varieties of soybean to organic NPK fertlizer addition. Theexperimental with Completely Randomized Design for Factorial 4 x 4 were used.The first factor was various varieties of soybean, consisting of four levels (Wilis,Orba, Kipas Putih, Anjasmoro) and second factor was different rate of organicNPK fertilizer, consisting of four levels such as 0, 250, 500, 750 kg each of hectare.The result of research indicates that interactian effect of treatment was significantto plant height, number of pod, number of filled out pod, and seed dry weight,the best treatment was addition 500 kg/ha of organic NPK fertilizer on Wilis thatproduced 308,26 g/plant, addition of organic NPK fertlizer increased productionup to 500 kg/ha.
