  To evalauate the influences of irrigation time with wastewater of Iran mayhes factory (producing leaven) on some morphological characters and yield of faba bean, a factorial experiment carried out on the base of randomized complete block design (CRBD) in Iran Mayehs factory farm in spring2012. Experimental factors consisted of irrigation times at 3 levels I1 = one irrigation with determined amount of wastewater, I2 = two irrigations with determined amount of wastewater, I3 = irrigation during the growth period of plants with determined amount of wastewater) and wastewater concentration at 6 levels (P0 = irrigation with normal water (control), P15=15% wastewaters + normal water, P30= 30% wastewaters + normal, P45= 45% wastewaters + normal water, P60= 60% wastewaters + normal water, P100= all wastewater) with three replications. Results showed that the effect irrigation numbers on traits such as plant height, number of pods per plant and seed yield was significant. Results also revealed that the effect of weastwater concentration on1000seed weight was significant. The interaction of number of irrigations by weastwater concentrations on stem dry weight was also signification. Evaluation of different treatments showed that 45 percent concentration of wastewater was increased traits under study. It seems, that controlled irrigation of bean with wastewater of factory (producing yeast) can be effective in improving its yield in the region. Manuscript profile

  Plant density is one of the important factors to be considered in crop management decisions to obtain high yield with optimum quality. In order to determine plant density effect on different rice cultivars an experiment was conducted in Tonekabon Rice Research Station in 2008. This experiment laid out as split plot in a randomized complete block design with 3 replications. The main plots were planting spaces with four levels (12, 14, 16 and 18 cm) and sub plots were rice cultivars (Shiroodi, Kados, Hashemi and Deylamani). Distance between rows was 30 cm in all treatments. ANOVA did not show significant differences for all characters (except filled and total grains) measured. Effect of cultivars on fertile florets and total grains was significant at 0.05 and on the other traits at 0.01 probability level. The highest grain yield 5787 kg.ha-1 was obtained at 18 cm plant spacing. The greatest grain yield 7374 kg.ha-1 was recorded for Shiroodi cultivar. Results showed LAI were greater at 12 cm plant spacing and CGR, RGR greater at 18 cm plant spacing and Shiroodi cultivar. Finally, according to the results, 18 cm plant spacing and Shiroodi cultivar can be recommended to the experimental area. Manuscript profile

  Medicinal plants in the field of natural resources are considered as one of the most important strategies in the field of health, trade and technology. Scientific and comprehensive knowledge of the elements and components of rangeland ecosystems is essential for their proper planning and management. For this purpose, the ecological characteristics of the habitat, morphological characteristics and the amount of some minerals of H. longiflorus Benth medicinal plant in the rangeland ecosystems of South Khorasan in two habitats of Amroodkan Ferdows Valley and Sabz Sarayan Valley were studied. Thus, 3 transects were established in the representative area of each habitat and 10 plots of 3 square meters were installed along each transect. In each plot, cover parameters including density, percentage of canopy cover of plant species, percentage of H. longiflorus Benth species, large and small diameter, medium height and some mineral compounds in plant aerial parts were measured. Also, climatic and topographic characteristics of each habitat and physical and chemical factors of the soil were measured. The results showed that the direction of both habitats was north and Amrudkan valley had higher altitude and average annual rainfall compared to Sabzerood. The soil of both regions was in the acidic range and the soil texture in the habitat of Amrudkan valley was loam and in Sabzrood habitat was sandy-loamy. Percentage of total species, percentage of Aroneh species, average height and wet and dry weight of flowering branches of the species due to more suitable ecological conditions and the presence of more fertile soil in the habitat of Amrudkan valley 17, 43, 12, 43 and 62% more, respectively. The habitat of Sabzrood was Sarayan. Also, there was a significant difference between the minerals in the medicinal organ of H. longiflorus Benth in the two habitats and the minerals in the flowering branches of this species were higher in the Emroodkan valley habitat than Sabzrood habitat. In general, the results show the influence of morphological and phytochemical characteristics of this species. Due to its medicinal value, having minerals and also high resistance of this plant to different environmental conditions, its use in urban green space belt is recommended. Manuscript profile

  In order to investigate the effect of interaction of mycorrhiza and humic acid on morphological characteristics, seed protein percentage, and nutrients concentration of red beans, an experiment was conducted as factorial randomized complete block design in three replications. Research factors included mycorrhiza at three levels of control, Glomus intraradice, Glomus mossea, and also foliar application of humic acid at three levels of control, 15, and 30 mg/l. The experiment was conducted as pot and under normal and uncontrolled conditions. Measured traits included plant height, root length, number of plant pods, number of seeds in each pod, 100 seeds weight, seed protein, and nitrogen and phosphorus concentration of leaves. Application of mycorrhiza and humic acid increased measured traits except for the number of seeds in each pod and 100 seeds weight. There was no significant difference between the two strains and also levels of 15 and 30 mg/l humic acid in the studied traits. Generally, foliar application of 15 mg/l humic acid in the presence of mycorrhiza was more effective than other treatments. Manuscript profile

  In order to assess the response of ajowan to drought stress that induced by PEG 6000 on germination and growth stages, two separate experiments that in each useed completely randomized design with three replications were done. In first experiment, the response of germination of ajowan seeds was investigated to different levels of drought stress include osmotic potential of zero (control), - 1/5, -2, -2/5 and -3bar that prepared by PEG6000. The second experiment was same first, but in this experiment, morphological and physiological characters of ajowan in different level of drought stress were evaluated. Results of Anova at our data showed that drought stress has significant effect (p≤0/01) on germination characters such as germination percentage, germination rate, height of plumule, length of radicle, dry weight of radicle and plumule. Mean comparison of treatments showed, with increase in drought stress, all the above characters have been reduced. Morphological traits such as leaf area, fresh and dry weight of shoot and root and shoot dry weight ratio to root decreased under drought stress. Also, drought stress had a significant effect on the amount of proline and soluble sugars in the aerial part and root. Comparison of mean of treatments showed that, with increasing stress, the amount of proline and soluble sugars in the shoot and root increased (p≤0/01). The results showed, that germination parameters were reduced by drought stress. Ajowan showed differently responce to tolerate drought stress. Ajowan plant for tolerance to drought stress has different reactions, including reduction of traits such as leaf area and dry and fresh weight of aerial part and root and increase traits such as proline content and soluble sugars.

  Water deficit is a great constraint for agricultural productivity world wide. Mungbean is a traditional pulse in arid and semi-arid areas. This research was conducted in a research greenhouse at the Ferdowsi university of Mashhad to investigate the impact of five drought levels (-0.3, -3, -6, -9, and -12 bar) on yield and morphological characteristics of eight mungbean genotypes (Jalagon17, Kopergaon, D45-6, IlagS6A, MD15-2, MY-17, Berken, Kiloga). The experiment was conducted as factorial in completely randomized design with four replications. The genotypes were exposed to drought stress 10 days after emergence. Some parameters were measured during growing seasons including plant height, leaf number, flower and pod number, length and number of lateral branches. Results showed significant differences of genotypes in all studied parameters in the first stage of stress. Reduction in the flowering and podding time were also observed in most genotypes. Flower numbers was a suitable parameter in assessment of drought tolerant genotypes. Most measured parameters did not show significant differences in all drought stress levels, and interactions at the end of growth season. At this stage, weight of pods was the best index. At the end of growing season, all of the measured parameters showed a reduction with increasing levels of drought stress. The highest amount of all parameters were observed in field capacity (-0.3 bar). Among the levels of water potential tested, -3 and -6 bars were the best treatments for evaluating drought stress of mungbean genotypes. Among studied genotypes, D45-6, Ilag S6A, and MD 15-2 were the best ones in terms of responding to drought stress. Manuscript profile
