Second factor are giving ameliorants: without ameliorant, calsite lime, natural rock phosphate and kirinyuh green manure. Parameters observed are plant heigh, harvesting date, penicle length, productive tillering amount, percentage of grain pithy, 1000 grain weight, dried grain weight, weight dry straw plant, ratio of grain and straw. Result showed the interaction between varieties of upland rice by giving ameliorant just happened harvesting date while plant heigh and penicle length just be effected by variety and dried grain weight effected by ameliorant.
