| Abstract | ||||
| The experiments were conducted in Agricultural Scientific Research Center in Al-Raqqa in Syria as spring season, using three manures (cow manure, olive solid waste, and peanut compost) with four levels (25-50-75-100) ton/ha for two years (2006-2007) as spring season using potato (Draga variety). The obtained results showed the degree of divergence between kind of manures for characteristics (plant, soil), was vast on the first year of use manures. However, the opposite was recorded at the second year (accumulative effect). Increasing of level manures produced greater values of EC (soil salinity), OM (organic matter), and lower pH of the soil. It’s preferrable the use of cow manure firstly, peanut compost at the second, olive solid waste at the end, for the best productivity and soil characters by using moderate level for productivity, and high level for soil characters. At the same time the use of low and moderate level of manures yearly, and the high level alternately. | ||||
