This study was carried out for determination of the effects of perforated and standard plastic covering materials and different mulching materials, namely, transparent plastic and straw mulches, on the growth and early yield of cucumber. Cvs. Çengelköy and Hylares F1 were used in the study. Plastic films with 40 or 80 m2 perforations and standard covering plastic were used as covering materials and transparent plastic films and straw were used as mulching materials for low plastic tunnels. The highest early yield was obtained from the plastic grown in low plastic tunnels covered with the plastic with a perforator of 40 per square meter and combined with plastic mulch for Cv. Çengelköy while Cv. Hylares grown in low plastic tunnels with 40 perforations per square meter and straw mulch gave the highest value. In general, the convenient results were obtained from combinations with 80 perforations per square meter for Hylares in terms of plant height increase rate while 40 perforations per square meter gave the better results for Cv. Çengelköy . The number of plants with disease symptom were higher in plants grown with standard plastic covering materials than those of plants grown with perforated plastic film.
