Abstarct: In order to study about effect of cow manure, urea fertilizer and Nitroxine manure on some physical and chemical properties of soil and yield of forage corn, an experiment was carried out on Amiran of Damghan as spilt plot factorial with random complete blocks design as main plot with 3 replication at 36 exprimental plots. Main factor , cow manure (D) was on 2 levels : d1 : no consume (use). d2: use 20 ton/ha and sub factor that to break to pieces on main factor was contain ,Urea manure on 3 levels : (n1:100 kg/ha , n2: 150kg/ha and n3: 200kg/ha ) and Nitroxine manure (B) was on 2 levels: (b1: no use , b2: use as inoculation). Results of Anova showed that Cow manure cause to increase saturation percent , organic carbon , total nitrogen , adsorption capable phosphorous , exchangeable potassium , sodium , sodium adsorption ratio , porosity percent and decrease on apparent special weight of soil , while urea fertilizer just cause increase total nitrogen in soil. Nitroxine manure also increase organic carbon , total nitrogen in soil , adsorption phosphorous, exchangeable potassium significantly. Interactive effects between cow manure and urea fertilizer was significant on organic carbon , and interactive effects between cow manure and urea fertilizer and nitroxine was significant on exchangeable potassium . also, EC , pH , texture soil , Ca ++ , mg ++ , Anions of soil parameters were not effected by the manure treatments .On plant Domesticated animal manure cause increase highly , dry weight of seed , corn-cob, skin of maize , maize , stem , leaf , total plant weight , and increase leaf surface , biological yield , and ratio between dry weight of seed to dry matter weight. Urea fertilizer cause increase all parameters above and dry weight wreath of flowers. nitroxine like that cow manure cause increase all parameters significantly except dry weight wreath of flowers and ratio of dry weight seed to dry matter . Iteractive effects between cow manure and urea fertilizer , were effected dry weight of seed , skin of maize , maize , leaf , stem , total plant , biological yield and ratio between of dry weight seed to dry matter. Interactive effects between domesticated animal manure and biological manure was significant on dry weight of seed , skin of maize , maize , total plant , biological yield and ratio of dry weight seed to dry weight matter. Dry weight seed was effected by interactive effects urea fertilizer and biological manure . Interactive effects of cow manure , urea fertilizer and biological manure was significant , just on dry weight seed , leaf and maize . to summarize cow manure and biological manure cause recovery some of physiochemical properties of soil , also increase yield corn and because gathering chemical manure on soil cause destroy soil, so we can use composting these manures to prepared field for reach to organic agriculture in large surface .
