A split plot experiment using a randomized complete block design with four replications was conducted at the research field of Agricultural Sciences and Natural Resources University of Khuzestan to study effects of sugarcane compost on some morphological and physiological traits of triticale under conditions of stress caused by irrigation cessation. The main plot factors included four levels of irrigation (complete irrigation, irrigation cessation from spike emergence to physiological maturity, irrigation cessation from pollination to physiological maturity and irrigation cessation from grain milk-dough stage to physiological maturity). The subplot factors included five levels of compost prepared from sugarcane residues (0, 10, 20, 30 and 40 tons per hectare). ANOVA indicated that the interaction effects of irrigation and compost on leaf area index and plant height were significant at the 1% and on chlorophyll a, b and total chlorophyll at the 5% levels. Comparison of the means revealed that the highest leaf area index value (7/75), the tallest wheat plants (11/92 cm), the largest content of chlorophyll a (20/98 mg/g fresh weight), chlorophyll b (15/20 mg/g fresh weight) and total chlorophyll (35/10 mg/g fresh weight) belonged to the treatment of complete irrigation together with 40 tons of sugarcane compost per hectare.
