Abstract:

Saline water has been successfully applied to crops via drip irrigation. However, application of saline water through this irrigation system in combination with polyethylene mulch has not been evaluated yet. Two experiments were carried out under greenhouse conditions to evaluate effects of saline irrigation (ranging from 0.2 up to 9.0 dS.m-1 and from 0.5 to 4.5 dS.m-1, respectively) and polyethylene mulch on the yield and water use efficiency (WUE) of sweet peppers (Capsicum annuum L.). Soil temperature was higher under an infrared-transmitting polyethylene mulch than under a black mulch or bare soil. Mulched plants required less water at all salinity levels than plants grown in bare soil. Salinity levels above the control (0.2 and 0.5 dS.m-1) significantly reduced total and marketable yield and WUE. Mulched plants had greater WUE and significantly higher marketable yields than those grown in bare soil. Fruit size and pericarp thickness were significantly reduced with increasing salinity; total soluble solids (TSS) increased. Soil salinity was reduced with the use of plastic mulches relative to bare soil.
