- Abstract
This work aimed to study the effects of irrigation with saline waters in an area cultivated with melon on soil salinity and pH. The experiment was conducted in the Santa Julia Farm, Mossoró city, Rio Grande do Norte State, Brazil, during the years 2001 to 2002. Water with different salinity levels (0.6; 1.9; 3.2 and 4.5 dS m-1) was used throughout the cycle and in incremental way in three periods of melon development, forming 15 treatments, arranged in randomized blocks with four replications. The salinity was measured at 0, 30, 50 and 70 days after sowing in soil samples collected in layers of 0-15, 15-30 and 30-45 cm. There was greater accumulation of salts in the surface layer (up to 15 cm) in all salinity levels and the use of more saline water produced higher average salinity in the profile. The average values of pH were within the range of optimal absorption of nutrients required by melon.
