Abstract

To evaluate the effect of irrigation intervals and different mulches on some traits of gladiolus cv. Rose Superme, an experiment was carried out as factorial arrangement in randomized complete block design with three replicutions in 2007-2010 growing seasons at Varamin Agricultural Research Center, Varamin, Iran. Experimental factors included: three levels of irrigation intervals 7, 10 and 15 days and five mulches no mulch, white plastic, wheat straw, pine dry leaves and black plastic. Plant height, spike length, floret number, flower diameter, corm diameter, corm and cormels weight were measured and recorded. Results showed that irrigation interval × mulch interaction effect was hightly significant (P < 0.01) on floret number, corm and cormels weight, and cormel number. Growing season also significantly (P < 0.01) affected all traits except corm diameter. In conclusion, irrigation at 10 days interval with black plastic mulch can improve quantity and quality of gladiolus production.
