Abstract Increasing population and water shortage in arid regions have challenged food security. Optimal water management and the use of compounds such as doudab and salicylic acid, by improving the physiological processes of plants, contribute to greater water efficiency and sustainable production of crops. This experiment aimed to investigate the effect of foliar spraying of doudab (1 and 1.5 liters per hectare), salicylic acid (0.5 and 1.5 mM), and control (spraying with water solution) on the yield and yield components of peanut plants under different irrigation cycles (once every 10 days, once every 20 days, and a combination based on seasonal conditions), was conducted in a split plot based on a randomized complete block design with three replications in the research-educational farm of the Agricultural College of Ravansar County in 1402. The results of variance analysis showed that irrigation interval and its interaction with foliar application had a significant effect on traits such as dry weight of full pod, dry weight of seeds, dry weight of pod skin, dry weight of roots and shoots without pods, hundred-seed weight, number of pod types (immature, empty, full, double and total per square meter) and ratio of pods (immature to total and full to total). Also, foliar application of fumigation and salicylic acid showed a significant effect on all these traits except number of immature pods, ratio of immature to total pods and seed size. The results of segmentation showed that the interaction effect of irrigation interval and fumigation concentrations and foliar application of fumigation and salicylic acid on various traits such as dry weight of seeds, roots, shoots, hundred-seed weight, number of pods (immature, empty, full, double and total), and pod ratios was significant at the 1% probability level. The results of the mean comparison showed that the best yield was observed under the conditions of 10-day irrigation interval and foliar spraying with a concentration of 1.5 l/ha of fumigation and 1.5 mM of salicylic acid. Under these conditions, the dry weight of the seed was 220 g, the number of filled pods was 283 per square meter, and the seed size was 1.42 cm. Also, the application of salicylic acid reduced the number of empty pods. Under the conditions of 20-day irrigation interval, the yield was generally reduced, but foliar spraying with fumigation and salicylic acid reduced the negative effects of drought stress. Under the conditions of 10-day irrigation interval and without foliar spraying, the dry weight of the seed was 190 g and the number of filled pods was 240, which indicates the positive effect of foliar spraying under optimal irrigation conditions. These results showed that the combination of regular irrigation and foliar spraying with optimal concentrations can help improve yield and reduce the effects of drought stress in peanut plants.

The parasitoid wasp, Habrobracon hebetor (Say) (Hym., Braconidae), plays a crucial role in the biological control of lepidopteran larvae. However, producers face significant challenges in storing and maintaining the quality of this wasp during cold storage, as the production process for both the wasp and its host takes approximately two months. Optimal cold storage is essential not only for preventing a decline in the wasp's quality but also for ensuring a constant supply of sufficient and timely quantities. This study investigated the impact of feeding during a four-week cold storage period on the mortality rate and biological characteristics of H. hebetor. This study was conducted experimentally under laboratory conditions. The host, Mediterranean flour moth larvae (Ephestia kuhniella Zeller), was reared at a temperature of 27±2°C, with a relative humidity of 65±5%, in darkness. The parasitoid wasp, H. hebetor, was reared at a temperature of 25±2°C, with a relative humidity of 65±5%, and a photoperiod of 16L:8D hours. Adult wa   of the same age were kept in a refrigerator at 5±1°C under two conditions: without feeding and with feeding using a diluted water and honey solution (1:5 every 48 hours). In each condition, at least 20 pairs of adult male and female wa   of the same age were observed. After verifying the normality of the data, statistical comparisons were made using one-way ANOVA, and treatments were grouped using the Tukey HSD test. The results of this study demonstrate that feeding the parasitoid wasp H. hebetor during cold storage positively impacts the quality and efficiency of the wa  . Specifically, providing a diluted water and honey solution reduced mortality, increased oviposition, and improved parasitism, without affecting the sex ratio. Feeding during cold storage can prevent high mortality rates and reduce quality loss and inefficiency in H. hebetor. These findings can assist producers in optimizing storage methods and maintaining wasp quality, ensuring a consistent supply of high-quality wa   when needed for biological control.

  This study wasconducted as 2x4 factorial experiment with the aim of investigating the effect of adding chicory root powder,artichoke leaf and stem powder,and Bacillus subtilis bacteria to the basal diet of laying hens on production performance,egg quality traits,egg cholesterol levels,some blood serum parameters,and intestinal histomorphology at the end of the production phase. 336 Lohmann LSL Lite laying hens at the age of 77 weeks were distributed in 8 treatments with 7 replications and six birds in each replication and fed with experimental diets for 98 days. The control group (without additives) had lower egg production,egg mass,villus height,crypt depth,and serum uric acid,total cholesterol,HDL and LDL,and higher feed conversion ratio,cracked eggs,unmarketable eggs,and yolk cholesterol concentration compared to all experimental groups. The effect of the simultaneous presence of all three factors as feed additives on egg production,cracked eggs,unmarketable eggs,mortality,yolk ratio,albumin ratio,yolk to albumin ratio,shell ratio,crypt depth,and villus height was significant. The group that was fed the basal diet with chicory root powder alone had the highest levels of serum uric acid,total cholesterol,total protein,and LDL compared to the other experimental groups.The group that was fed the basal diet with the simultaneous presence of all three factors had the highest levels of serum triglycerides and HDL. Adding chicory root powder with Bacillus subtilis bacteria or adding artichoke leaf and stem powder with Bacillus subtilis bacteria to the basal diet of laying hens had a significant effect on villus width. The group that was fed the basal diet with artichoke leaf and stem powder alone had the highest villus height and crypt depth,and the group that was fed the basal diet and Bacillus subtilis alone had the highest villus width and villus height to crypt depth ratio. The presence or absence of experimental factors alone or together as additive to the basal diet had no statistically significant effect on egg weight produced,shell less eggs,small eggs,body weight change,egg shape index,Haugh units,yolk index,yolk weight,albumin weight,yolk height,albumin height,shell thickness,shell weight,breaking strength,egg specific gravity,and serum parameters including uric acid,triglycerides,total protein,blood glucose,total cholesterol,HDL,and LDL.

  Abstract   The Hircanian forests of Iran, located in the north of the country and in the three provinces of Gilan, Mazandaran and Golestan, are the most industrial and important forests of the country, the area of ??which is estimated to be about 1.9 million hectares. These forests with high species and genetic diversity and great age, which belong to the third geological era, are a lasting and valuable heritage.   But unfortunately, it is always threatened by fire as a phenomenon of natural and human origin. Although fire is an inseparable part of the forest ecosystem, this phenomenon is one of the most important factors in the destruction and destruction of these ecosystems. Fire causes changes and transformations in the function and structure of ecosystems, including the forest ecosystem, and has a very destructive effect on natural processes such as reproduction, seed bed, carbon and nitrogen cycles andsequence, diversity of species and wildlife, physical, chemical and soil fertility characteristics.In this research, fire occurrences of 23-year period (2001-2023) of Hyrcanian forests were obtained from MODIS sensor and 11-year period (2012-2022) from VIIRS sensor. Then these events were examined in terms of time (month, season and year) and place (physiography) and their relationship with physiographic characteristics (percentage of slope, direction of slope, altitude >The results of the frequency of fire incidents with time factors showed that the highest number of incidents was in 2021 with 70 incidents and the least in 2016 with 16 incidents. In terms of monthly review, three consecutive months, namely January with 59 cases, December with 71 cases and November with 50 cases, have the highest number of cases. The lowest number was in May with 11 cases and then April with 22 cases. In terms of seasonal analysis, the most events are in the autumn season.The investigation of spatial factors (physiography) showed that the slope >Also, the spatial pattern of fire occurrences during a 23-year period using MODIS and VIIRS sensor data showed that fire occurrences from a distance of 20 to 40 km have a random pattern and from a distance of 40 to 65 km have a cluster pattern. The results of time series analysis using ARIMA model showed that the peak of fire events until 2026 was similar for VIIRS and MODIS data, but the number of predicted events using VIIRS data is more than MODIS sensor.Key words: fire - Hyrcanian forests - modeling - prediction

Zagros forests have been faced with many fires in recent years, so they can be aware of the effect of fire on trees and shrubs and their revitalization process can begiven to the vegetative response. After the fire, the forest was used to takeappropriate measures and operations to restore Zagros forests. Therefore, in this study, using Landstet satellite images, OLI sensor was examined during the period of 1399-1399 to investigate the recovery process of covering after fire. According to the date of fire in each of the areas studied, images were created before and after the fire, and the monitoring of the burnt areas was carried out at an annual interval with the image. April was considered to investigate the forest floor coverings and images of August and September to investigate the forest tree cover. NDVI and NBR indexes were used to investigate the recovery process of the vegetation and were determined by the results of the DNBR index. Due to the impact of rainfall on the masses of forest cover, rainfall data were used during the period 1396-1396. It is a vegetable cover and the increase in fuel and the risk of fire. Therefore, in the current research, the forest type and the intensity of fire were considered as factors affecting the process of forest recovery. It should be noted that in the Iranian oak type in the Jalalvand area and the Iranian-Mazodar oak in the Rijab area, the NBR and NDVI index recovery speed was higher than the Cormo-Renjen Brigade in the Qalajah area. In general, in forests where fires have been less severe, the process of repair is faster and in more severe fire floors, the repair is longer. The results of this study indicate that the NBR index is appropriate to investigate the timing of forest recovery in Zagros forests.

  Forest statistics has an important role in forest management and provides information on forest parameters; Without forest statistics, due to the lack of sufficient information for planning and implementation, it is not possible to have sustainable management. The purpose of this research was to evaluate the effectiveness of different formulas for estimating the density of distance sampling methods as fast and low-cost methods for estimating the density of oak trees. With this aim, a polygon with an area of nine hectares was selected in Zardlan Sardsir forests of Ilam province and some of their characteristics were measured by the 100% statistical method and also by measuring the distance-azimuth between the trees, a spatial map was prepared. Then, in the field of statistics, 50 walking sampling points were carried out in AutoCAD software, and 6 distance sampling methods including nearest person, nearest neighbor, T-square, combination, common point and square method were implemented in each point. After obtaining the available distances in distance methods, different estimators of each method were used to calculate density. The results showed that the estimators of Cottam et al. (1953) and Diggle (1975), Cottam and Curtis (1954) and Heydari et al. Using the accuracy criterion had better performance than other estimators

   Land use means the type of land use to meet human needs, in other words, land use change means both a change in the structure and function of a specific type of use (qualitative change) and a change in the spatial space and extent of that use (qualitative change). And it has always been one of the most important factors through which humans affect the environment. The development of land cover and land use change is needed not only to prevent it but also to manage and plan a case. This research is the construction and prediction of land use changes in Ravansar region using satellite images and geographic information system. For this purpose, Landsat satellite images of 2020, 1990, and 2010 were prepared. Satellite images were analyzed for geometric and radiometric errors. For this purpose, six land use classes in the studied area were determined and a land use map was prepared for the studied years. The results showed that in the last 30 years, a total of 31,248.62 hectares of land has been changed. In addition, using the logistic regression model, the effect of physiographic and human factors was evaluated, which showed that land use change has a direct relationship, while with the factors of slope percentage, height above sea level, distance from the road, distance from residential areas And. The distance from water sources has an indirect relationship. The CA-Marcov model, which is a combination of the automatic cell model and the Markov chain, has been used to predict land use change in 2030 and 2040. The valid model is also based on the night map made in Year. 2020 was done with the actual map of the same year and the Kappa coefficient obtained from the comparison with the value of 95.49% indicates the high ability of the model in simulating land use changes for the future.

2). One-way ANOVA was used to compare mean of soil properties for Tape-Gole, Sorkhak and their relevant control and T-test was used to compare soil properties for Gheshlagh and its relevant control. The results showed that there was no statistically significant changes of soil EC, PH, TNV in all the studied area. The amoughnt of OC%, P, K and BD in Sorkhak was significantly higher compare to its relevant control area. Among the measured soil microbial properties there was no significant changes in soil BR in all the studied area. However, soil carbon biomass (Cmic) and qCO2 was significantly higher in Sorkhak compared to control and Tape-Gole. The results showe that none of the measured soil properties was affected by the implementation of Sianat plans in Gheshlagh compared to its relevant control. It was concluded that the quality of the implementation of Sianat plans is very important issue to improve the soil properties.  

Most scale insects (Hemiptera: Sternorrhyncha: Coccoidea) are agricultural pests and natural resources in different parts of the world and cause great damage to important crops and other plants each year. Mites (Arachnida: Acari) associated to scale insect, plays several roles such as predator, parasite, decay eater, carcass eater, fortic, honeydew eater, symbiotic and use of waxy cover as shelter on plants. mites can feed on some Diaspididae scale insect or use some Pseudococcidae and Coccidae as shelters, therefore, some mites can reduce the pest population without the use of pesticides. In this study, which was conducted between 2019 to 2021, relationships between mites associated to scale insects in Kermanshah region were studied and identified. For this study , parts of the host including the trunk, twigs and leaves infected with scale insect were cut with garden shears and transferred to the laboratory. under binocular mites associated with scale insect were isolated and stored in 70% ethanol. Also, the lice were separated from the twigs and transferred into 70% alcohol glass with the same number as the related mites glass. Labels with sampling information installed on glass. Microscopic slides were prepared to identify scale insects and mites. during this study, 17 mites species from 16 genera belonging to 11 families related to 10 scalre insects species of nine genera and five families were identified as follows and relationships between them were determined. one of these mites is a new species for the world and one species for fauna mites in Iran is a new report.

   In addition to its economic role in the country's development, the forest contributes to environmental protection and biodiversity, reducing pollution, regulating temperature, protecting water and soil, and consequently reducing soil erosion and increasing water resources. Therefore, the purpose of this realization is to evaluate the structure of Zagros forest Structureand quantitatively evaluate its impact while also comparing the impact of different forest, rangeland and agricultural land uses on hydrological components and soil physical and chemical properties in part of the river basin. Death is located in Chahar Azar in Kermanshah province. Accordingly, an area with degraded forest land (with severe, medium and low level of degradation) along with rangelands and agricultural lands was selected. In the study area, three forest mass with a total area of ??0.5 hectares and all characteristics Trees were measured in the desired area and then the nearest distance sampling method was applied in this area. Subsequently, the study area was divided into three compaction categories. Hydrological parameters were measured in each forest condensation area and in both agricultural and pasture land uses. Precipitation was run at a rate of 83 mm / h for 24 minutes. Rain simulation was repeated six times per user. Samples of surface soil (0-20 cm) were collected along each plot to study the soil characteristics of each land use. The results showed that sample fragment 1 and 2 have random distribution pattern and sample fragment 3 has clumped distribution pattern and based on the accuracy criterion for estimating the quantitative characteristics of density and canopy cover presented by Byte and Ripley give better results for the approach of the nearest person to mass one and for estimating height for masses one and three. The results of soil studies in three forest mass showed that the physical and chemical properties of soil in the three studied mass were not significantly different, while the percentage of organic matter and nitrogen in the three forest, pasture and agricultural land uses were not significantly different. So that the amount of nitrogen and organic matter in forest and rangeland soil was higher than agricultural land. Rainfall simulation results also showed that runoff time, suspended sediment load, sediment concentration and runoff coefficient were not significantly different in the three studied populations, but the volume of runoff produced was significantly different between treatments. Species with masses one and three were statistically equal and both were less than mass two. But in the three land uses the volume and coefficient of runoff and load and sediment concentration were significantly different between treatments, so that the volume and coefficient of runoff were higher in forest mass and sediment load and concentration were lower than the other two uses. On the other hand, the results of organic matter loss measurements showed that there were no significant differences among the three forest mass, but there was a significant difference among the three land uses so that more organic matter forest land Wasted by the rain. Therefore, one of the most important services and functions of forest ecosystems is to prevent soil erosion, which should prevent soil erosion in the country by preserving and preventing deforestation and changing land uses.

  AbstractThe structure of forest stands changes over time due to human or natural disturbances.   Investigation of these changes in relation to environmental factors and turbulence plays an important role in the dynamics analysis and management ecosystems. In order to better understand the forest ecosystems and its dynamics, it is necessary to study the forest structure and its order in a quantitative manner. Zagros forests as one   of the most extensive vegetation habitants in the country and the second important forest ecosystem of Iran, although not very important in terms of industrial wood production. Due to its important role in regulating water and soil and ecological interaction of the region, the purpose of this study was to investigate the changes in the structure of Kermanshah Sorkh­ Dizeh forest after a thirteen year period. In order to this survey, in first   fifty circular plots in a 100m*100m network   with geoplaner software were denoted and then in this stand, the forest structure characteristics that measured in thirteen years ago, in circular plots were carried out. The results showed that dominant species (Quercus brantii ) and spatial pattern of stand (clumped distribution) have not been changed. The density of stand was decreased in thirteen years ago, 178.4 trees per hectare in 2005 decreased to 119.4 trees per hectare in 2018, but the canopy cover of   trees in this stand was increased from 1676.490 m2ha-1 in 2005 to 1767.09 m2ha-1 in 2018. In this period the percent of stand canopy cover changed from 16.77% to 17.67%.   The percent of stand canopy cover as canopy cover was not significant. In summary, the results showed that dominant species, spatial pattern of trees, canopy cover and percent of canopy cover of this forest were not changed but trees density of stand was decreased and statistical surveys improved this matter.   Keyword: Structure – density – canopy cover – circular sampling method – spatial pattern

  Abstract  Due to the importance of Zagros forests in Iran, especially in terms of water conservation, soil and biodiversity, optimal management is needed. Zagros forests have been susceptible and fragile due to irregular exploitation in recent years and are not in desirable condition in terms of density and canopy cover. Therefore,   awareness of the density and canopy status of Zagros forests is important for their preservation, restoration and expansion. Therefore, timely access to statistics and information in these forests seems necessary in order to manage and plan them. This study aimed to investigate changes in some quantitative characteristics of a natural Quercus brantii stand in a statistical period of 13 years in Sorkhe Dize forest of Kermanshah. For this purpose, 50 sampling points were considered as sampling centers in the study area and using geoplanner software, a grid of 100 meters by 100 meters was designed within the area and then the coordinates of these points were entered into GPS and stored. Then in the forest area ,after finding points within the target stand on the ground by applying distance sampling point center quarter method(PCQM)   and T square method at each specified point, target characteristics (species, two diameter of the canopy   and …) of the trees were measured and recorded in the sampling forms. The results of data analysis over the 13-year period showed that in the T square sampling method the density and canopy cover decreased from 111.4 nha-1 and 2374 ha-1 in 2005 to 109.59 nha-1 and 1983.86 ha-1 in 2018. The results also showed that in the point center quarter method (PCQM) the density and canopy cover decreased from 76.62 nha-1 and 2171 ha-1 in 2005 to 42.47 nha-1 and 933.99 ha-1 in 2018. In both sampling methods, the distribution of the number of canopy level >  Keyword: forest – canopy cover – density- distance- sampling

  The grapes is from one important products of garden in the words and Iran. This value crop use, of for certain reason product is fresh, ra  erry, oil and so on. The most important limiting factor the growth   of fruit trees in arid and semi arid regions is deficit   available water. The use of nutritional, such as the of appropriate fertilizes, can improve plant Performannce   in underwater conditions. This research was carried out to investigate of seedless grapes under water stress conditions with 4 treatments and 2 water treatmeant in 4 replications was conducted as a factorial experiment in a randomized complete block design. The treatments including of: control treatment (without fertilizer) and potassium sulfate, compost and biochar treatments ( 10 g, 5 and 10 %), water treatment 40 and 80(control), field capacity, till the occurrence of stress indication was done. Collected data was analyzed by SAS software. The results showed that potassium sulfate increased soil and plant potassium. The compost increased phosphorus, sodium, electrical conductivity, soil organic carbon and nitrogen, iron, zinc and copper. Biochar also increased potassium. Organic carbon, potassium and phosphorus plants. Biochar and compost under water stress conditions increased leaf RWC, photosynthesis, tra  iration, stomatal conductance, chlorophyll and protein. Peroxidas enzymes and superoxide dismutase had the lowest amount under water stress conditions in biochar fertilizer treatments. Compost and biochar are more effective in improving the condition of grapes under the conditions of water stress chemical fertilizers of potassium sulfate.

  Without a doubt, today the issue of preserving water resources exploitation and maintenance of the necessary economic efficiency, especially in the arid and semi-arid LIFE. This planet is like Iran has a double importance. One of the solutions proposed in recent decades in the management of water resources, surface and groundwater conjunctive use of water resourceses. he main objectives of this study, the simulation interaction between groundwater and surface water using dynamic connection between surface water and groundwater in the plain is cantilevered, So that the data and results on a monthly basis between the surface water and the groundwaterش MODFLOW WEAP is in circulation. Therefore, at each time step of monthly values, influence the balance of rivers, runoff, etc. WEAP model to model MODFLOW groundwater level values, the flow between the aquifer and so calculation and simulation models, WEAP back and this process will continue until the end. Another key goal is to optimize the amount of monthly withdrawals of groundwater and surface water is to fund the planning period.so To perform system optimization, multi-objective model NSGA-II. was used . So that in its first objective maximization of the needs of the project in the second goal of minimizing groundwater level decline during the period was utilized. The decision variables in this model, including the percentage of withdrawals from surface and underground water resources, which were defined as seasonal. The simulation results showed the biggest drop in the region of West and Southeast parts of the northwest and the Lower Plains. That due to the density of operational wells and water in these areas is approximately 11 meters. The northern and north eastern plains, due to lack of exploitation wells and agricultural lands is more fed. And thus a drop in groundwater level in these areas is not high.and Most edema related to a part of the northern part of the study area is approximately 25 meters. This is due to the high rise part of the study area is extremely fed. Also with the three scenarios defined for this study, results showed that if the current pattern and the reference scenario without optimization on average 16.82% of the surface water and groundwater funded by 83.18 percent. After optimization percent of the groundwater in the study area picked up about 5 percent and   the average percentage of optimal supply from surface water and groundwater, respectively, 78.84 and 21.16%, respectively. The optimal scenario the reliability needs of land Pshmynhzar 26% ش 3.2 and 2.6 meters.It means that by construction balarood dam and application scenarios System Optimization average groundwater level to 2.3 meters would improve.
