Efeitos de diferentes níveis de salinidade de água e de lâminas de irrigação na bananeira nanica. IV. Evolução da salinidade no solo.

Abstract

The effects of different salinity waters (0.5 to 2.5 dS/m) and irrigation depths (varying between 100 to 120% of water requirement) in evolution of soil salinity under Nanica banana cultivated during 24 months were studied. Results indicated salt accumulation in soil upto a depth of 90 cm during summer period and decrease during winter. Higher salinity levels proportionated more pronounced salt accumulation while the water depths did not infleuence evolution of salinity.
