This research is conducted at Tunyang village of Timang Gajah subdistrict of Bener Meriah district, Aceh provice from march to July and the reasearch used randomized block design (RBD) factorial 12 treatment combine with 3 replications, so there are 36 experimental units. As factor was the experiment of green manure Thitonia by dose of 0 ton per hectare ( T0), 5 tonnes per hectare (T), 10 tonnes per hectare (T2) and 15 tonnes per hectare ( T3) while dose of inorganic fertilizer NPK were 400 kilogram per hectaer ( P1), 800 kilogram per hectaer (P2) and 1.200 kilogram per hectaer (P3) . Result of research shows green manure Thitonia affected significantly wet weight of wheat biomass , no real effected on height of wheat on age 15, 30, 45 days after planting , percentage of flowering age 43-50, 51-58 and 59-66 days after planting, length of panicle, number of grain per panicle, dry weight of biomass wheat, weight of grain wheat per hill, weight of grain per plot , wheat harvest per hectare and weight of grain wheat 1000. Thitonia green fertilizer is best found at 15 tonnes per hectare ( T3). Inorganic fertilizer NPK affected significantly on the weight of wet and dry wheat biomass, no real effected on height of wheat on age 15, 30 and 45 days after planting, the percentage of flowering age 43-50, 51-58 and 59-66 days after planting, length of panicle wheat, number of grains per panicle, weight of grain wheat per hill, weight of grain wheat per plot , wheat harvest per hectare and weight of grain wheat 1000 . Inorganic fertilizer NPK is best encountered at 1.200 kilogram per hectare ( P3 ). The highst wheat yield of treatment combine is found on T2P3 by the yield is 1.75 ton per hectare.
