| Abstract | ||||
| A field experiments was conducted in the experimental station of the agricultural scientific research centre at Al-Raqqa, Syria using potato as the test crops through the spring season. Three organic fertilizers namely sheep manure, wheat compost and municipal solid waste were added to soil at the rates 25, 50, 75 and 100 tone/ha in order to study their influence on soil characteristics and potato productivity in comparison with chemical fertilization. Results obtained showed that increasing the rate of organic fertilization increased ece and soil organic matter contents but decreased soil pH with significant differences due to the kind of organic fertilizer. For satisfactory productivity and soil characteristics. The used organic fertilizers showed the order sheep manure < wheat compost < municipal solid waste. The use of organic fertilizers resulted in higher potato yields in comparison with the use of chemical fertilizers in the first season; no definite trend was observed in the second season, however the level (75 tone/ha) for all studied organic fertilizers showed higher yields than those with the chemical fertilizers. | ||||
