Evaluation of Drought Stress on Yield and Physiological Attributes in Cantaloupe Crop (Cucumis melo L.)

Mani F.

Abstract :

This research was conducted in order to study the effect of different irrigation regimes on yield and it’s compenents and on water use efficiency of melon. It was realized in the experimental station of the High Agronomic Institute of Chott Mariem, University of Sousse (Tunisia) during 2013 season. Full irrigation (I 100) and two deficit irrigation (I 70 and I 40) strategies were examined based randomized completely block design (RCBD) with threereplications. Chlorophyll a Chlorophyll b, Total Chlorophyll, Total Crop Yield, main stem length, total leaf area, chlorphyll stability index, mean number fruit per plant, mean fruit weight, Brix and Water Use Efficiency were determined. Leaf Relative Water Content, Water Saturation Deficit, Leaf Water Content and leaf water content per unit leaf area were also determined. Results showed that yield was maximum with full irrigation (5.2 t. ha –1). This irrigation regime gave maximul main number of fruits per plant (5.2), main fruit weight (1603 g), and maximum total leaf area (94361 cm). Otherwise, maximum total chlorophyll content (0.0028 mg. g FW–1) and chlorophyll stability index (137.5) were recodered at moderate water stress (I 70). So it’s prefaerable to use full irrigation regime to obtain maximum yield.
