Abstract:
The aim of this study was to determine the interaction between ameliorant and
varieties on soybean growth and P nutrient uptake in Ultisol soil at Warmare. This research was conducted using a randomized block design (RAK) in two factors, namely ameliorant (A) of manure as the main factor consisting of 3 levels including: A0 (without ameliorant), A1 (chicken manure) and A2 (goat manure). Soybean varieties (V) as the second factor included: V1 (Anjasmoro) and V2 (Wilis). The results showed that the interaction between ameliorant and variety siginificantly affected plant height at 5 week, number of trifoliate leaves at 3 week, number of branches and nutrient uptake of P. Giving goat manure
ameliorant to Anjasmoro variety produced the highest plant (48.42 cm) at 5 week. The application of chicken manure and goat manure to the Anjasmoro variety produced the highest number of trifoliate leaves (5.00 pieces) at 3 week. In the variable number of branches, the Wilis variety which was given goat manure obtained the highest number of branches (5.66 branches). The highest nutrient uptake of P (9.77 g) was found in the Anjasmoro variety which was given chicken manure
