Abstract

Background and Objectives: Iran is located in a warm and dry area and optimum consumption of water by a method that does not damage the plant is of great importance. Since there no research has been on the effect of bentonite and Superabsorbent polymer on drought tolerance of chicory in Birjand city, and from water optimization cases, use of bentonite and Superabsorbent polymer has been, in this study, the effect of different Cultivation litter on the performance of chicory was investigated. Materials and Methods: The experiment was conducted at the research farm of the Faculty of Agriculture, University of Birjand, 2017-2018. The growth period was 120 days. In this study, the effects of bentonite, Superabsorbent polymer, Drought stress and the combination of bentonite and Superabsorbent polymer were investigated on parameters of leaf area, fresh and dry leaf weight, relative water content of leaf, fresh and dry root weight and water use efficiency of chicory. This research was a completely randomized design with treatments including irrigation as main factor at two levels of 50% and 100% water requirement and Cultivation litter as sub factor at 6 levels without Superabsorbent and bentonite (witness), 125 kg Superabsorbent polymer per hectare, 4. 5 kg bentonite per plot, 2. 5 kg bentonite per plot, 4. 5 kg bentonite per plot + 125 kg Superabsorbent per hectare and 2. 5 kg bentonite per plot + 125 kg Superabsorbent per hectare. Results: Generally, Drought stress had a significant effect on chicory yield. Also, the highest average dry weight of leaf in effect of irrigation and different levels of Cultivation litter at two levels of 100% and 50% irrigation was 3686. 66 and 2453. 33 kg/ha, respectively. The highest average in effect of irrigation and different levels of Cultivation litter on root fresh weight at two levels of 100% and 50% irrigation was 3626. 6 and 2526. 6 kg/ha, respectively and the highest average root dry weight in effect of irrigation and different levels of Cultivation litter at two levels of 100% and 50% irrigation was 1276. 6 and 903. 3 kg/ha, respectively. According to the obtained data from this study, the lowest amount was related to the witness treatment and the highest amount was related to the combination treatment of 4. 5 kg bentonite and Superabsorbent polymer. Conclusion: The results showed that Drought stress treatments was effective on all investigated traits and reduced these traits. Application of different Cultivation litter had positive effect on plant growth and was able to increase plant resistance to water stress and show the highest yield of chicory in Birjand climate conditions.
