Proceedings... Valencia: FAO: international Union of Soil Sciencesc2001  aThe objective of the work, which was carried out in the Experimental Station of Caatinga of Embrapa Semi-Árido, in Petrolina-PE, was to evaluate effects of different salt levels in irrigation water and the soil conditioning Sper Salt (polimaleic acid) on beetroot crop (Bela vulgaris, L.) cv. Earley Wonder. Treatments were: water with 0.1, 4 and 8 dS/m and water withO.I, 4 and 8 dS/m plus Sper Salt. Results showed productivity varying from 20.00 to 65.50 ton/ha for treatment with saline water plus Per Salt and for treatment with São Francisco River water (fresh water), respectively. There was not significant difference between salinity levels 4 and 8, which productivity were 29.40 and 26.30 tonlha, respectively. It was observed that Sper Salt was more efficient at salinity levei of 4 dS/m than at 8 dS/m.  aSoil  aManejo  aSalinidade  aSolo  aManagement  aSalt  aSoils  aVale do Sao Francisco1 aMORGADO, L. B.
