The dust is one of the natural hazards of arid and semi-arid regions, including Iran. When this problem coincides with the drying up of the largest salt lake in the Middle East (Lake Urmia), the occurrence of a salt dust storm will be inevitable, which will have profound effects on human communities, animals and plants. On the other hand, agriculture and the growth of crops are also strongly affected by dust deposition on the leaf surface. Therefore, in order to investigate the effect of dust on growth and some physiological characteristics of three important crops in Azerbaijan, namely wheat C3 monocot (Triticum aestivum L.), corn C4 monocot (Zea mays L.) and chickpea C3 dicot (Cicer arietinum L.), a completely random experiment designed with three replications. Treatments included two levels of dust (zero and 10 grams of dust per m2), Application of dust for 3 days had no significant effect on wheat growth. Maize responded to this environmental pollution by increasing growth and chickpeas by decreasing growth. The content of photosynthetic pigments decreased in chickpea leaves, increased in wheat and remained constant in corn. Dust increased the sugar content of corn and peas. Also, exposure to dust had little effect on the total protein content of wheat and corn, while the protein content of chickpeas showed a significant and clear decrease. Changes in the various parameters of the studied plant species can be considered as an adaptation to protect plants against dust stress. Corn and wheat seem to be more resilient, but chickpeas are stunted. Selecting a suitable crop species for cultivation in areas that receive a large amount of salty dust annually can be one of the important strategies to reduce the adverse effects of dust on the agricultural economy.

In this study, a randomized complete block design with 36 plants in Shiraz vineyard with simulated peeler, washing and control treatments was used to study the effect of microgravity on grape varieties. After applying the treatments, chlorophyll a and b, branch length, leaf relative water content, dry weight and leaf area as vegetative and biochemical traits, fruit formation, number of cubes per panicle, panicle weight, sugar percentage in cabbage and yield as traits Productivity of grapes was measured. Data analysis was done by analysis of variance and comparison of the meanings with Tukey test. The results showed that desert racecrine reduced the vegetative and reproductive traits of grapevine. Chlorophylls a and b were decreased 13.6% and 34.5%, respectively. Branch length and leaf relative water content did not change under threshing stress, but dry weight and leaf area decreased by 61.6% and 34.4%, respectively, and the difference between treatments was significant at 5% probability level. The leaves were washed out to eliminate the effect of the microtubules on plant growth and there was no difference between the treatment and the control. Formation of fruit is the most important phonological stage of garden trees, which is a significant reduction in insemination and formation of cabbage in grapevines. Reducing cabbage formation reduced the weight of the cluster and eventually decreased the yield by three times the plant yield and the difference was significant at the probability level with washing and control at 1% probability level. Washing the plant after spraying the thimble removed it from the leaves and the flowers opened the grapes and increased the yield of the plant, and with the control in one floor. The occurrence of reindeer phenomenon at pollination and inoculation stage can reduce fruit and yield formation.
