1 - Estimation of water productivity of wheat in Droudzan irrigation and drainage network, Fars Province, Iran
Elnaz Noroozi Hossein Babazadeh Majid VazifedoustIrrigation management, water use efficiency determination and provision of efficient solutions for increasing of limited water resources productivity are based on accurate estimation of crop yield and actual water consumption which its exact measurment is very difficult MoreIrrigation management, water use efficiency determination and provision of efficient solutions for increasing of limited water resources productivity are based on accurate estimation of crop yield and actual water consumption which its exact measurment is very difficult without proper tools. In this regard, Doroudzan irrigation and drainage network of Fars Province in Iran was divided into 86 simulation units using GIS. Water balance components and crop yield were determined in each spatial unit during a 10-year period (2000-2010) using distributed SWAP model and through MATLAB software programming. There was good correlation between the observed and simulated wheat yield amounts in each simulation unit. After validating of the model, the water balance components were simulated by calibrated model and the average water productivity in the Doroudzan network was estimated. The results showed despite decrement in water use in the network, water productivity has been increased means that higher yield can be produced by water managenment. Estimating of water balance components and yield production in the network, especially in crisis situations and water deficit condition can be used for agricultural water management evaluation and finding ways to increase water use efficiency.

In current study, environmental potential of Mazandaran Province was evaluated for rapeseed cultivation. The climatic data of the synoptic and climatological stations of the province such as temperature, rainfall, day-growth rate, sunshine, freezing days and relative humidity from 2001 to 2015 related to each phenological stage of rapeseed and environmental capability data such as land use capability, soil depth, elevation, slope and its direction were collected. To prioritize and evaluate the criteria for rapeseed cultivation, a hierarchical process analysis method was used. Then, weighing of the prepared layers based on the criteria and model, spatial analysis of information was carried out using TOPSIS model in GIS environment and a final evaluation of land suitability for canola cultivation was prepared. Finally, Mazandaran province was divided into four unlimited, low, moderate and high-limited regions for rapeseed. The results showed that a large part of Mazandaran Province has ecological potential for rapeseed cultivation. Manuscript profile -

In current study, the effect of salicylic acid on morphological and physiological traits of common mallow and Moldavian balm was studied based on completely randomized block design in farm condition at Bostanabad county, Iran. Plantlets were sprayed by 0, 150 and 300 mg/L salicylic acid two month after planting and two weeks after. In flowering stage, the plant height, stem, root and internode length, leaf, root and lateral roots number, dry and fresh weight of stem, root and leaf, dry matter percentage of root, stem and leaf and also chlorophyll content were recorded. Salicylic acid spraying improved all common mallow traits but root number and length. In Moldavian balm, salicylic acid application increased all traits. However, it decreased root and stem dry matter percentage and had no effect on root number and length. Also, 300 mg/L of salicylic acid was more effective than 150 mg/L in common mallow traits except dry leaf weight and root dry matter percentage and in Moldavian balm expect length internode. Thus, foliar spraying of salicylic acid can be recommended for as a simple and economical method for yield and growth indices improvement of common mallow and Moldavian balm. Manuscript profile -

Speedfeed and Pegah, an experiment was conduct in Agricultural and Natural Recourses Research Center of Jirof in 2014. Experimental design was split plot based on randomized complete block in three replications. The main plots were three irrigation levels including 33, 66 and 100% of plant water requirement and sub plots were forage sorghum cultivars. Drought stress affected significantly on all studied traits such as fresh and dry forage yield in both cultivars. Also, drought stress caused decrement in total fresh yield in forage sorghum. In intensive and moderate drought stress fresh forage yield decreased up to 47 and 17% comparing to normal irrigation, respectively. Pegah cultivar in both stressed and none-stressed conditions had higher yield than Speedfeed. Raw protein, fiber and ash percentage increased by improvement in drought stress condition. Also, these qualitative traits in Pegah were better than Speedfeed. In deficit water condition in forage sorghum cultivation, it is possible to use drought resistant cultivars and decreasing of irrigation intervals especially in sensitive plant stages and harvest higher amounts of forage yield Manuscript profile -

There are some solutions for reducing its damages. Among them, using bio-fertilizers and environmentally friendly in the production process can be mentioned. In this regard, a factorial experiment was conducted based on completely randomized design with three replications in 2014. The first factor was salinity in 0, 30 and 60 mM rates, and the second factor was amino acid including arginine, tryptophan and proline. The interactive effects of salinity and amino acids on the number of pancakes, proline content, electrolyte leakage percentage, total chlorophyll content, and their simple effects on stem length, the number of leaves and nodes were significant. With an increase in salinity level, stem length, the number of leaves and nodes decreased. Amino acid consumption increased the number of leaves, but proline showed a more positive effect in the number of nodes and stem length. The negative role of proline salinity and positive role of proline in the number of pancakes and total chlorophyll content and the positive role of salinity in increasing the amount of proline and the percentage of leaf electrolyte leakage were significant. Therefore, under the conditions of salt stress in the fields as well as increased soil salts and irrigation water in the greenhouse, the growth conditions in tomato can be improved by using biofertilizers.

The seeds were kept in liquid nitrogen at -196 °C for 1 week. The flowering shoots resulted from the treated seeds were collected and dried in the laboratory condition and their essential oils were obtained by hydro-distillation method. The essential oil compositions were determined using analytical gas chromatography and gas chromatography coupled with mass spectrometer (GC/MS). Finally, 15 and 16 componentswere identified in the essential oils in the cryopreservation and control groups, respectively. The main components in the essential oil were carvacrol, p-cymeneand and thymol. Regarding the type and percentage of compounds existing in the essential oil, there was no significant difference among the control and cryopreservation treatments. Therefore by cryopreservation technique, the seeds of this valuable endangered species could be preserved for a long period and its extinction may be avoided. Manuscript profile -

To evaluate autotoxic potential of root exudates in four rice Iranian cultivars including Hassansara, Hashemi, Champa, and Ali Kazemi, an experiment was conducted using donor and receiver cultivars culturing on 0.4% agar medium. Receiver plantlets were planted on agar in a concentric circles pattern aroud donar plantlets in 2, 4 and 6 cm intervals after donors seven days establishment. The plantlet indices such as radicle and plumule length, plantlet dry and fresh weight were recorded. The results are indicating negative effects of root exudates of Iranian rice cultivars on themselves and each other. The negative effect was more obvious on plantlets radicle then plumule growth. Root exudates of Hassansara had the highest negative impact on Champa plantlet growth. Plantlet fresh weight increased significantly in growing intervals of 2, 4, and 6 cm in all rice cultivars. Champa root exudate was more autotoxic than others regarding plantlet dry weigh. Therefore, using proper planting density in studied rice cultivar especially Champa has been suggested to get suitable yield in rice plantations. Manuscript profile
