The ameliorative effect of poultry manure, added as a fertilizer to salinized soils, was studied in pot experiments at four rates of manure: 0, 10, 20 and 32 tonsiha and four levels of irrigation water salinity: 0.26, 1.0, 1.5 and 2.5 mmhos/cm applied to soils classified -Vertisols and Entisols sown to snapheans (Phaseolus vulgaris L.) in Northern Sudan (Khartoum State). The results obtained indicated that shoot dry matter and pod dry matter yields and both of leaf N and P contents were significantly decreased as the salinity of irrigation water increased. Conversely, the magnitude of the above mentioned parameters increased significantly as the rate of manure addition increased suggesting yield and nutrients uptake advantages from the addition and incorporation of manure i;: salt-affected soils. On the other hand, both salinity and manure levels enhanced uptake. In general, the growth of plants was better on the Vertisols than on the Entisols.
