In order to study the effect of mycorrhiza inoculation and zeolite-enriched manure compost on photosynthetic pigments content and qualitative properties of triticale grain, a factorial experiment in a completely randomized complete block design with four replications were conducted at Research Field of Agricultural Sciences and Natural Resources University of Khouzestan during 2016-2017 growing season. The experimental factors included mycorrhiza application at two levels (application and non-application of mycorrhiza), and mixing of zeolite to manure in six levels (0, 5, 10, 15, 20 and 25% w/w of zeolite/manure). According to the results, under conditions of mycorrhiza application with increasing zeolite up to 15% leaf greenness index (SPAD) increased but decreased afterwards. The highest chlorophyll a (2.68 mg g^-1) was obtained from 15% zeolite treatment and the lowest (1.82 mg g^-1) was detected in control. Mycorrhiza inoculation caused a 14% increase in carotenoid content compared to non-inoculation. Grain phosphorus content (0.43 mg kg^-1) was increased in mycorrhiza inoculation condition compared to non-inoculation (0.37 mg kg^-1). Under inoculation conditions, the highest grain yield (3510.7 kg ha^-1) belonged to application of 10% zeolite. Under non-inoculation condition more zeolite was needed (in compare to inoculation treatment) to obtain the highest grain yield. The highest protein yield (329.97 kg ha^-1) was obtained from mycorrhiza inoculation treatment with 15% zeolite and the lowest protein yield (1152 kg ha^-1) was obtained from mycorrhiza inoculation treatment with 25% zeolite. Finally, the results of this study showed that the application of zeolite in manure and inoculation of mycorrhiza fungi can increase the concentration of photosynthetic pigments and grain quality of triticale.
