Thanks to its palatability and high digestibility, chicory plays an effective role in increasing domestic animals’ products. In order to study the effect of sowing data and nitrogen fertilizer levels on some characteristics of chichory (Cichorium intybus L.), an experiment has been conducted in a split plot design, using randomized complete blocks design with three replications at the Agricultural Sciences and Natural Resources University of Khuzestan in 2016-2017. The factors include four sowing data (22 October, 5 November, 21 November, and 5 December) as the main plots and four levels of nitrogen (zero (non-application), 75, 150, and 225 kg / ha) as subplots. Results show that the sowing dates have only affected chlorophyll meter index, dry matter digestibility, and digestible energy, whereas nitrogen has had a significant effect on all studied traits. Increasing the application of nitrogen to 225 kg / ha increases plant height, chlorophyll meter index, leaf area, and branch number, not to mention both fresh and dry weights of the plant. The treatment of 225 kg / ha nitrogen raises the fresh weight of shoots and the percentage of forage protein by 66.35% and 6.44%, respectively, compared to non-application. But in these two traits, no significant difference has been observed among nitrogen application levels in different planting dates. In this study, late planting date led to better conditions for most physiological, morphological yield, and quality characteristics. Accordingly, it is turned out that October 22 till November 5 sowing date with 150 kg ha-1 fertilizer has been the best treatment for chicory cultivation in Ahvaz.

In order to evaluate the effects of irrigation intervals, mycorrhizal fungi and zeolite fertilizer on some Mung bean traits, a factorial splitting experiment was conducted in a randomized complete block design with four replications in the Izeh region in July 2015-1016. The main factor included irrigation interval at three levels (7, 10 and 13 days) and various factors were Mycorrhiza inoculated (inoculated and non-inoculated) and zeolite (without consumption and 2 tons per hectare) as a factorial.The results of analysis of variance showed that only interaction effect of irrigation, mycorrhiza and zeolite on stem weight, number of seeds per pod and water use efficiency were significant. The highest grain yield was observed in irrigation intervals of seven days under inoculation and non-inoculation with fungus, as well as irrigation intervals of 10 days in inoculated mycorrhizal fungus. The use of zeolite in irrigation intervals of 10 and 13 days increased the most of traits. The results of water use efficiency showed that use of Mycorrhiza fungus and zeolite fertilizer increased water use efficiency. So that, by increasing the irrigation interval from 7 days to 10 days, using mycorrhiza and zeolite can prevent decreasing of water use efficiency. According to the results of this study, using mycorrhiza fungi and zeolite fertilizer can increase the irrigation interval of mung bean from seven to 10 days in the studied area.
