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 effects of irrigation interval and nitrogen on yield and some physiological characteristics of Fenugreek (Trigonella foenum-gracum L.), an experiment was carried out as split plot in randomized complete block design with three replications at Islamic Azad University of Birjand, 2009. Treatments included irrigation intervals (4, 8 and 12 days) as main plot and nitrogen fertilizer (0, 50, 100 and 150 kg.ha-1 urea) as subplot. Results showed no significant differences for seed yield in irrigation treatments after 4 and 8 days. Increasing N also led to the increase of seed yield but no significant difference was found for seed yield between 100 and 150 kg.ha-1 urea. Decreasing in water use led to the increase of Na, proline and carbohydrate and decrease of K, Cha, carotenoids and total pigments, but it had no significant effect on Chb. Nitrogen significantly increased chlorophyll a, carotenoids, total pigments, and K. Increasing N up to 50 kg ha led to the increase of carbohydrates but then reduced the carbohydrates of leaf. According to the results obtained in this experiment, it can be stated that Fenugreek is somewhat drought tolerant and considering the importance of this medicinal plant, it can be used in conditions of water scarcity as an alternative for the species that have lower economic value under water deficit.

In order to improve seed yield and enhance the quality of medicinal plants, the establishment of sustainable agricultural aystems and utilization bio-fertilizers is considered of great importance. In order to study the effect of bio-fertilizers on yield and yield components of pot marigold (Calendula officinalis L.), an experiment was carried out as factorial in randomized complete blocks with 8 treatments and 3 replications in 2010. Treatments included compost (vermi-compost, city refuse compost, no organic fertilizer, granular organic fertilizer) and phosphate bio fertilizer (inoculated, not inoculated). Mean comparison was carried out using Duncan’s Multiple Range Test at 5% level). Results showed that phosphate bio fertilizer had not significant effects on plant height, flower yield, number of flower and grain harvest index but flower diameter, number of lateral stems, biomass yield, seed yield and flower harvest index wrer significantly affected. Also, significant differences were observed in most of the traits between treatments and control (no fertilizer, no inoculation). Biological fertilizers significantly increased plant height, total biomass yield, seed weight and harvest index however, flower diameter, number of secondary stems, dried flower yield, flower number per square meter and seed yield were not affected by treatments. The highest values of most of the traits were obtained at vermi-compost and phosphate bio fertilizer, affecting the yield components and seed yield of pot marigold positively.
