An experiment was carried out during the period of January to July/2010, in municipality of Areia, Paraiba State, Brazil, in order to evaluate effects of the irrigation with saline water, bovine biofertilizer and drainage of the soil on water consumption and growth of neem seedlings. The experimental design was in randomized blocks using factorial 5×2×2, referring to five levels of saline water (0.5; 1.5; 3.0; 4.5; 6.0 dS nr-1) in soil without and with bovine biofertilizer and in pots without and with drainage. In plants the water consumption, growth in height, stem diameter, number of leaves, dry matter of roots, aerial part and total dry mass were evaluated and in soil the electrical conductivity of saturation extract - EC was determined. The bovine biofertilizer, after dilution in non saline water (0.49 dS nr-1) e no chlorinated water in 1:1 ratio was applied once two days before sowing, equivalent to 10% of substrate volume. Irrigation was applied daily with each water type applying volume sufficient to maintain the soil with water content at level of field capacity. From results the increase in salinity of water inhibited the water consumption by plants independently of the soil with or without bovine biofertilizer. The salinity of water in soil with and without bovine biofertilizer also reduced the growth of neem plants but with more pronounced effect in the treatments without application of organic fertilizer to soil in liquid form.

Salt excess in soil and water used for irrigation can cause significant loss of production and growth in cultivated plants. Among some options for reduction of negative effects of salts to plants in cultivated areas, fermented bio fertilizer has been used to grow vegetables and fruit tree irrigated with saline water. The study aimed at evaluating the behavior of the noni plant to salinity of the irrigation water in substrate with and with no bio fertilizer. Treatments were arranged in a randomized block design with four replications, using a 5 × 2 factorial arrangement. Five levels of electrical conductivity of irrigation water (0.5, 1.5, 3.0, 4.5, 6.0 dS m-1) were used in substrates with and with no bio fertilizer. Parameters were evaluated as follows: plant height, stem diameter, number of leaves, leaf area, shoot dry matter and water consumption. All evaluated variables were negatively affected by the increase in salt concentration of the irrigation water, but always with less intense effects in treatments with bio fertilizer.The bio fertilizer does not eliminate, but mitigates the negative effects of salts in noni plants.
