To compare some ecomorphological, phenological and phytochemical properties of common mallow (Malva sylvestris L.) in two regions Ferdows and Tabas, three habitats from each region were randomly selected and studied in 2018. Soil analysis of the habitats indicated the growth of the plant in sandy loam soils. On the other hand, the soil of these two habitats was alkaline with low salinity. Soil lime content was higher than crop soils. The results of phenological studies also showed that in Ferdows, this plant grows in early April and blooms in June. Then the seeds begin to ripen in late October and fall in late November. In Tabas, the plant begins to grow in the second half of March, flowers in May and flowering continues until early autumn. The seeds start to ripen in the second half of August and fall in early November. In Ferdows and Tabas, the recession period of plant activities coincided with dryness of the environment and the onset of the cold season, respectively. Phytochemical analysis of leaves, flowers, seeds, and stems extracts of the plant in two regions showed the presence of alkaloids, tannins, flavonoids, emodol or emodine, saponins, carbohydrates, starch, sterols, steroids, anthocyanosides, and cumarins in low to high amounts in each organ of the plant. Anthracenoside was not found in any of the three ethanol, aqueous and ether extracts. Also, four phenolic acids (linoleic, linolenic, synergic, and paracomaric acids) were detected by thin-layer chromatography (TLC) in seeds, stems, flowers, and leaves of the plant in both areas. The results also showed that the anthocyanin content of the leaves decreased with increasing the region's altitude.

In order to study the effect of drought stress and planting date on some traits of chichory (Cichorium intybus L.), an experiment was conducted in a split plot design using randomized complete blocks design with three replications at the Agricultural Research Center of Islamic Azad University, Birjand Branch in 2011-2012. The factors included were irrigations levels (%100, %75, %50 and %25 ET0) and planting date (16 March, 2 April and 26 April). Results showed that all traits were significantly affected by drought stress, except R/S. The highest plant height, root length, width and branches number, shoot dry yield, root dry yield, total dry biomass, R/S were achieved under %100 ET0 and the highest water productivity was achieved under %25 ET0. According to mean comparisons, the highest values for all traits, except R/S, were recorded for the planting date of 16 March. The interaction effects of factors were also significant for branches number, stem dry yield, shoot dry yield, root dry yield and water productivity. Totally, the highest yield and water productivity were obtained for the planting date of 6 March. In addition, no significant difference was recorded between the treatments of %50 ET0 and %100 ET0 in 16 March in terms of total dry biomass. Therefore, %50 ET0 could be recommended especially in water deficit condition.

In order to study the effect of irrigation interval, Nitrogen (N) fertilization and plant density on yield and yield components of fenugreek (Trigonella foenum-graecum L.), a split-split-plot experiment was conducted in Darmian, Iran in Spring 2010 based on a randomized complete block design with three replications. The main plots were irrigation interval at two levels of 5 and 10 days. The sub-plots were N fertilization at three rates of 0, 75 and 150 kg N.ha-1 from urea source and the sub-sub-plots were plant density at three levels of 22, 33 and 66 plants.m-2. According to the results of analysis of variance, irrigation interval significantly affected traits of pod length and water use efficiency (WUE) for seed and biomass production. In addition, main branch number per plant, pod length, seed yield, chlorophyll index and WUE for seed and biomass production, were significantly affected by nitrogen rate and plant density had significant effect on main branch number per plant and ring diameter. Means comparison showed that as irrigation interval was increased from 5 to 10 days, pod length decreased 8.7%, but WUE for seed and biomass production increased 40.5 and 47.5%, respectively. Also, as N rate was increased from 0 to 150 kg N.ha-1, main branch number per plant, pod length, seed yield, chlorophyll index and WUE for seed and biomass production increased by 23.5, 26.4, 23.2, 67.1, 72.3 and 71.5%, respectively. Moreover, with increasing of density from 22 to 66 plant. m-2, branch number per plant and ring diameter decrased 7.9 and 11.2%, respectively. In total, given the results of the study and the importance of water saving, it is recommended to use irrigation interval of 10 days with the application of 150 kg N.ha-1 and density of 66 plants.m-2 for the cultivation of fenugreek in Darmian, Iran.

In order to study the effect of drought stress at different growth reproductive stages and N fertilizer rates on some morphological and quantitative traits and water use efficiency (WUE) of fennel(Foenicolum vulgare Mill.), an experiment was conducted as a split-plot based on a Randomized Complete Block Design with three replications, at Research Field of Islamic Azad University of Birjand Branch in 2010. The main plot included irrigation at three levels (irrigation stop at start of flowering, and seed-filling stages, and optimum irrigation) and the sub-plot was N fertilizer at four rates (0, 60, 120 and 180 kg N/ha). Results showed that irrigation stop at start of flowering and seed-filling stages decreased plant height by 16.2 and 5.2%, fruit yield by 69.7 and 52.6%, essential oil yield by 72.9 and 31.4%, and WUE for essential oil production by 69.1 and 4.5%, respectively as compared to optimum irrigation treatment. Moreover, the increase in rate of nitrogen application from 0 to 120 kg N/ha significantly increased plant height, stem diameter, branch number of main stem and fruit yield, 5.8, 12, 15.5 and 24.3%, respectively. However, the highest yield and WUE for essential oil production was observed in 60 kg N/ha application treatment. In general, according to the results of current study, optimum irrigation with 60 kg N/ha application treatment can be recommended to achieve high essential oil yield of fennel in Birjand, Iran.

Nowadays, changes in cultivation pattern towards drought resistant species are proposed as a solution to tackle drought. To study the effect of irrigation levels and planting date on yield and water use efficiency of Hibiscus sabdariffa L., an experiment was conducted in the research field of agriculture college of Islamic Azad University of Birjand during 2010-2011. Three levels of irrigation (20, 60 and 100 percent evapotranspiration of source plant) as main plots and different planting dates (May 10th, June 1th and June 20th) as sub plots were studied in a split plot experiment with three replications in a randomized complete blocks design. The results indicated that different irrigation levels and planting dates had significant effects on number of flowers per square meter, dry and fresh weight of flowers, total biomass yield and water use efficiency (flower and biomass). The highest number of flowers per square meter (62.42), flower fresh weight (62.50 grams per square meter), flower dry weight (10.30 grams per square meter), total biomass yield (150.3 grams per square meter), water use efficiency of flowers (0.024 gram per) and water use efficiency of biomass (0.532 gram per liter) were obtained from the first planting date i.e. May 10th. Also, the highest number of flowers per square meter (55.88), flower fresh weight (72.40 grams per square meter), flower dry weight (11.46 grams per square meter), biomass yield (142.5 grams per square meter), water use efficiency of flower (0.042 gram per liter) and water use efficiency of biomass (0.897 gram per liter) were recorded for the irrigation level of 20 percent evapotranspiration of the source plant. Irrigation levels and planting dates had no significant effect on flower harvest index. The interaction effect of irrigation levels and planting dates was significant on flower dry and fresh weight, total biomass yield and water use efficiency (flower and biomass). The highest values of these traits were obtained at planting date of 10 May and irrigation level of 20 percent evapotranspiration of source plant. Generally, with regard to the early cold fall and long growth period of Hibiscus sabdariffa, its plantation is not recommended in Birjand climate. According to the results of this experiment, water requirement of this plant was low.

In order to study the effect of water deficit stress and different nitrogen levels on seed yield, yield components and water use effeciency of Calendula officinalis L., an experiment was conducted as split plot design based on randomized complete blocks with three replications, at research field of Islamic Azad University of Birjand branch in 2009. In this research water deficit stress set as main factor with three levels (irrigation after 60, 120 and 180 mm evaporation from pan class A) and nitrogen set as sub factor with four levels (0, 60, 120 and 180 kg N ha-1). The results showed irrigation trearments had significant effect (α=1%) on seed yield and it,s components, biological yield, harvest index and water use efficiency for seed and biomass. With incereasing of irrigation intervals from 60 to 180 mm evaporation from pan class A, seed number per capitul, number of capitul per m2, 1000-seed weight, seed yield, number and dry yield of flower decereased 26.6, 49.5, 39.6, 79.3, 65.6 and 72 percent, respectively. The highest biomass yield and weight of one capitul was releated to irrigation after 60 mm evaporation treatment, but irrigation after 60 mm evaporation treatment had the highest WUE. Also the results showed that nitrogen fertilizer trearment affected significantly (α=1%) all traits except capitul number per m2 nitrogen fertilizer application increased these traits, significantly. Interaction of irrigation and nitrogen on all traits was not significant. In conclusion, irrigation after 120 mm evaporation with 120 kg N ha-1 had suitable seed yield with the highest WUE for seed.

In order to understand the effects of sowing dates and plant density on fenugreek (Trigonella foenum gracum L.), an experiment was conducted at Torbat-e-Jam region in 2005. Four sowing dates (28 February, 19 March, 9 April and 29 April) and four plant densities (10, 20, 30 and 40 plants/m2) were compared in a split plot design based on randomized complete blocks with 4 replications. Sowing date had significant effects on seed yield and its components. The earliest and the latest sowing dates had the greatest and the lowest seed yield, respectively (88.34 and 22.3 g/m2). Also, these treatments had the greatest and the lowest 1000 seed weight (12.0 and 9.9 g) and pod number per plant (25.8 and 6.8). Harvest index was the lowest in the latest sowing date (29 April), because flowering and seed formation happened contemporary with high temperature. In addition, delay in sowing time reduced plant height, significantly. Plant density had significant effect on seed yield. Seed yield was the highest at 40 plants/m2. There was no significant interaction on different characters.
