Jujube (Zizyphus jujuba Mill.) is a horticultural-medicinal plant belonging to the family Rhamnaceae. This research was conducted to evaluate the morphological traits and phytochemical compounds of jujube ecotypesin Iran to achieve superior medicinal ecotype. The plan with fourteen jujube ecotypes of jujube collection of Jahad University of Southern Khorasan (Birjand) was carried out in spring-2018 in a completely randomized design with three replications. Leaf and riped fruit samples were evaluated morphologically and phytochemically. The results showed that the yield of 100-seed weight was positively and significantly correlated with fruit length, fruit width and length to fruit width ratio. Also, length to fruit width ratio and length to leaf width ratio had a positive and significant correlation with leaf width. The correlation of total flavonoid and total phenol traits with other phytochemical traits was not significant. Antioxidant capacity was significantly correlated only with total phenol. Analysis of variance of morphological traits showed that the studied ecotypes had a significant difference with each other, which indicates the existence of a variety of jujube germplasm in Iran. Based on the cluster analysis results, fourteen ecotypes were placed in two separate clusters. The results of this study showed that there is a considerable diversity in the studied ecotypes that can be used in breeding programs of the species.

In order to study the effect of low irrigation and nitrogen fertilization on morphological traits, sepal yield, and yield components of Roselle (Hibiscus sabdariffa L.), an experiment was conducted as split plot design based on randomized complete blocks with three replications, at Saravan, Iran in 2010. In this research, irrigation was considered as main factor with three levels (irrigation after 60, 120 and 180 mm evaporation from pan class A) and nitrogen rate was considered as sub factor with four levels (0, 60, 120 and 180 kg N.ha-1). The results showed that irrigation and nitrogen levels had significant effect on plant height, stem diameter, fruit number per m2, sepal fresh and dry yield, and biological yield. However, sepal dry weight per single fruit and sepal harvest index per fruit were only affected by irrigation, and sepal harvest index per plant was only affected by nitrogen. The interaction effect between irrigation and nitrogen significantly affect the sepal fresh and dry yield. According to the means comparison, increasing of irrigation intervals from 60 to 180 mm evaporation reduced the plant height, stem diameter, fruit number per m2, sepal fresh and dry yield, biological yield, and sepal dry weight per single fruit to 48.1%, 31.8%, 41.3%, 58%, 54.9%, 67% and 22.7%, respectively. In addition, the increased use of nitrogen from 0 to 120 kg.ha-1 could increase the mentioned traits to 13.7%, 8.6%, 37.1%, 43.3%, 44.1%, 25.5%, and 5.7%, respectively. Overall, according to the results of current study, irrigation after 120 mm evaporation with 180 kg N. ha-1 treatmentcould be suggested for roselle cultivation in Saravan, Iran.

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.
