Abstract

Using mulch to decrease and optimize water use is known as a practical method. For this purpose, a split-factorial experiment based on complete block design with three replications on two melon cultivars was conducted in spring season of 2010 in Torbat-e-Jam. Interval irrigation treatments in three levels (6, 8 and 10 days) were considered as main plot and mulch (straw plus paddy rice, plastic and no mulch) and cultivar (Khatooni and Ghasri) were considered as sub plots in a factorial design. Results showed that there was a significant difference between plactic mulch and the control and also between interval irrigation treatments for fruit yield, ripening period, suger percentage, fruit weight and number of fruits on plants .Interaction effect observed between interval irrigation and mulch for number of fruits on plants, marketable fruit, yield and ripening period traits. The shortest period of ripening was observed for the 8 and 10 dey interval irrigation together with plastic mulch. Plactic mulch caused the suger percentage of both cultivars to increase as well. Plactic mulch for 6 day interval irrigation caused yield and fruit quality to decrease, but it caused yield and fruit quality to increase for more than 8 day interval irrigation. Regarding the advantages of plactic mulch which is the decrease of water use and the improvement of yield and fruit quality, using plactic mulch is recommended for dry land.
