در اين پژوهش، كيفيت آب رودخانه ريجاب در چهار ايستگاه (R1 تا R4) با شاخص‌هاي كيفيت آب محاسبه شده شامل IRWQISC، NSFWQI و CWQI ارزيابي گرديد. بر اساس نتايج مدل IRWQISC، نمونه‌ها در رده‌هاي نسبتاً خوب تا بد توزيع شدند و تنها نمونه R1-15 در رده بد قرار گرفت، در حالي كه در شاخص NSFWQI تمام ايستگاه‌هاي R1 و R2 را در گروه بد و R3 و R4 را در گروه متوسط طبقه‌بندي كرد كه نشان از زوال كيفيت رودخانه دارد. در شاخص CWQI نيز همه ايستگاه‌ها را در رده ضعيف با مقادير ?? تا ?? قرار داشتند. تحليل فصلي نشان داد كه هر دو شاخص بر بحراني‌ترين وضعيت در ماه مهر اتفاق نظر دارند كه ناشي از رواناب‌هاي آلاينده اول پاييز و كاهش دبي رودخانه و تغليط آلاينده ها است، اما بهترين ماه‌ها را فروردين و آبان معرفي كردند كه نشان از رقيق شدگي آلودگي ناشي از افزايش بارندگي است. ارزيابي كيفيت آب رودخانه براي پرورش ماهي قزل‌آلا، نشان داد كه ايستگاه‌هاي R3 و R4 به دليل دماي پايدارتر و آلاينده‌هاي كمتر مناسب‌تر و R1 و R2 كاملاً نامناسب هستند، به ويژه اينكه آمونياك غير يونيزه در برخي نمونه‌ها از حد بحراني ???? فراتر رفته است. همچنين محاسبه انديس‌هاي خورندگي (LSI، RSI، PSI) نشان داد كه آب در همه ايستگاه‌ها خاصيت خورندگي شديد دارد و پتانسيل رسوب‌گذاري ندارد. بر اساس يافته‌هاي اين تحقيق، مجموعه اقدامات مديريتي پيشنهادي آن است كه اولويت آن، كنترل فسفات و مس است كه بايد با كاهش مصرف كودهاي فسفاته، تصفيه پساب مزارع پرورش ماهي از طريق تالاب‌هاي مصنوعي و حوضچه‌هاي ته نشيني انجام شود. دومين اولويت، كنترل آلودگي آلي و نيتروژني با جمع‌آوري و تصفيه فاضلاب روستاها و كليه خانه باغهاي احداث شده در بالادست رودخانه، احداث نوارهاي حائل گياهي و بهينه‌سازي تراكم و سيستم هوادهي استخرها است. با توجه به الگوي فصلي، پايش كيفيت در ماه‌هاي خشك و گرم بايد به صورت هفتگي تشديد گردد. براي مقابله با خوردگي شديد، استفاده از لوله‌هاي پلي‌اتيلن يا PVC به جاي فلزي و تزريق كنترل‌شده آهك توصيه مي‌شود. در سطح راهبردي، تدوين استاندارد محلي سخت‌گيرانه‌تر براي تخليه پساب، ايجاد صندوق حمايت مالي براي تجهيزات تصفيه و تشكيل كميته مديريت حوضه آبريز با حضور دستگاه‌هاي متولي ضروري است. در نهايت، رودخانه ريجاب به دليل فشار شديد ناشي از فعاليت‌هاي آبزي‌پروري و كشاورزي، در آستانه يك بحران يوتريفيكاسيون (انباشت نيتروژن و فسفر) قرار دارد و در صورت عدم اجراي اقدامات پيشنهادي طي چند سال آينده، تنوع زيستي آن به شدت كاهش يافته و براي مصارف آينده غيرقابل استفاده خواهد شد. واژگان كليدي: رودخانه ريجاب، شاخصهاي كيفي آب، IRWQISC, NSFWQI, CWQI

  Abstract Introduction: Shallot is one of the medicinal and industrial plants that is harvested from natural habitats in our country. In Iran, this plant is considered an unauthorized plant in terms of exploitation of natural resources due to the special conditions of its habitat and reproduction. Given that most of this species is collected from nature, the increased demand for this type of species has caused their destruction and excessive exploitation in nature. Accordingly, the present study was conducted with the aim of identifying obstacles and solutions to the development of shallot cultivation in agricultural lands and pastures of Al-Ashtar County. Methodology: To achieve the research objectives, a qualitative approach was used. The participants in the study were experts from the Natural Resources Department and the Agricultural Jihad Department of Al-Ashtar County, residents of Dartang and Hindi villages of Al-Ashtar County, and farmers under the contract of the Zarrin Cooperative Company, and 22 people were selected as samples based on the Barez purposive sampling method. The data collection tool was semi-structured in-depth individual interviews and field notes, and interviews continued until data saturation was reached. For data analysis, the method of communicative content analysis and open and axial coding was used. Results: The results of the study showed that in relation to the obstacles and challenges of preserving and revitalizing shallots in the natural areas and habitats of Al-Shatar County, 13 categories were identified, including marketing and sales obstacles, advertising and information obstacles, financial and capital risks, human and social risks, infrastructure obstacles, skill and technical obstacles, standards and quality, information obstacles, knowledge and educational obstacles, management and support obstacles, organizational obstacles, production inputs, environmental and geographical conditions, and licensing of medicinal plants. Also, in relation to the strategies for cultivating shallots among the shallot farmers of Al-Ashtar County, 9 dimensions were identified: research and training strategies, advertising and information strategies, technical and agricultural strategies, structural and support strategies, policy strategies, strategies related to issuing licenses for the exploitation of shallots, economic and social strategies, trade and organizational strategies, and strategies related to marketing and sales. Discussion and Conclusion: As it was identified, the improvement and development of the medicinal plant market, especially shallots, requires cooperation and coordination between different organizations. Abstract, discrete and uncoordinated action in implementing policies and strategies in the research, promotion, production, trade, processing, health and treatment sectors makes it difficult to achieve goals. In order to make a coordinated, targeted and effective effort in organizing the medicinal plant market, efforts should be made to formulate a comprehensive program in which the goals are completely clear and the duties and responsibilities of the various sectors are determined. The development and implementation of this program will enable the evaluation of the performance of various organizations and prevent waste of time and capital.

Abstract Rapid population growth and the increasing needs of society on the one hand, intensive production of agricultural products in arid and semi-arid regions, and the lack of use of fertilizers containing potassium (K) on the other hand have caused the depletion and reduction of the availability and varying rates of potassium release in Iranian soils. Also, the excessive use of chemical fertilizers and improper management in the agricultural sector have faced the country's soils with a shortage of organic matter. In a study conducted during 1402-1403, the effects of various organic fertilizers on potassium forms and biological activities in soil were investigated. Initially, two different soil samples were collected from a depth of 0-30 cm, considering mineralogical differences. Six types of organic fertilizers—cow manure, chicken manure, sheep manure, compost, vermicompost, and mealworm frass manure—were added to soil samples at a concentration of 1.5%. These samples were then incubated for 60 days under controlled conditions, with a temperature of 25°C and maintained at field capacity moisture. At the end of the period, measurements were taken for potassium forms, basal respiration (BR), substrate-indued respiration (SIR), microbial biomass carbon (MBC), and metabolic quotient (qCO2). The results indicated that incorporating various organic fertilizers significantly influenced potassium forms and biological activities in both soils at a 5% probability level. In Soil 1, the highest levels of soluble potassium were found in the chicken treatment (173.8 mg kg?¹) and the frass treatment (167 mg kg?¹). The frass treatment also had the highest exchangeable potassium (542 mg kg?¹) and non-exchangeable potassium (1130.60 mg kg?¹), while the cow treatment showed the highest structural potassium (6580.06 mg kg?¹). In soil 2, the highest level of soluble potassium was found in the chicken manure treatment, measuring 303.5 mg kg?¹, followed closely by the frass treatment at 296.66 mg kg?¹. The frass treatment also exhibited the highest exchangeable potassium at 1343.66 mg kg?¹. In terms of non-exchangeable potassium, the chicken manure treatment had the highest value at 2326.66 mg kg?¹, while the frass treatment showcased the highest levels of structural potassium, measuring 7502 mg kg?¹.

   Abstract Chickpea (Cicer arietinum L.) has the largest cultivated area among legumes. It not only provides a cheap protein diet, but also can improve soil fertility due to its nitrogen fixation ability. Kermanshah province is one of the top provinces in the country in terms of chickpea cultivation area as this crop is considered the second crop of most rainfed farmers in the province. Therefore, conducting applied research in the field of chickpea cultivation is of great importance. This field experiment was conducted in Sarbekuh village, Homeyl district, West Eslamabad-e Gharb county, in split plots in a randomized complete block design. The land was divided into 4 blocks and each block had 28 plots. The main plots included the control (without zinc sulfate and humic acid), soil application of zinc sulfate at a rate of 20 kg/ha, soil application of humic acid at a rate of 5 kg/ha, and soil application of zinc sulfate +   humic acid at a rate of 20 and 5 kg/ha, respectively, and the subplots included the control (without foliar application), foliar application of zinc sulfate at a concentration of 2 kg in 1000 L at podding time and before and after flowering, foliar application of humic acid at a concentration of 2 kg in 1000 L at podding time and before and after flowering, and foliar application of zinc sulfate + humic acid at concentrations of 2 + 2 kg in 1000 L at podding time and before and after flowering. The results indicated that the highest 100-grain weight was related to the soil application of zinc sulfate + humic acid at a rate of 1.42 g, which was not significantly different from the zinc sulfate treatment. Comparison of the simple effects of soil treatments showed that the highest biological yield was obtained in the zinc sulfate + humic acid treatment with an amount of 3250 kg/ha. Comparison of the simple effects of soil treatments showed that the highest biological yield among foliar treatments was related to the zinc sulfate + humic acid before and after flowering with an average of 3364 kg/ha. The highest amount of grain nitrogen (3.3%) was related to the foliar application of humic acid before and after flowering without soil application of zinc sulfate and humic acid. In general, the results showed that the foliar application of zinc sulfate + humic acid before and after flowering had the greatest effect among the treatments on the yield and yield components of chickpea. The soil and foliar applications of zinc sulfate and humic acid significantly increased the amount of nitrogen and grain protein, while they had no significant effect on the amount of phosphorus, potassium and zinc in the grain.

   Abstract Introduction: Development activities impose risks on the environment, and the dimensions of these potential risks vary depending on the nature of the project and environmental sensitivities. Brick kilns have a high impact potential. Therefore, by assessing the environment and providing an appropriate management plan, the potential negative impacts arising from them can be reduced as much as possible and the affected environment can be improved. Accordingly, the present study was conducted with the aim of analyzing the sustainable management of lands covered by brick kilns in three areas: land degradation, land use change, and land cover, in Godin Rural District, Kangavar County. Methodology: To achieve the research objectives, an integrated (qualitative-quantitative) approach was used. A qualitative method (phenomenology) was used to identify the threats of brick kilns and the lived experiences of residents of target villages of brick kilns, and to identify and prioritize the necessary solutions for sustainable management of lands covered by brick kilns in Godin Rural District, Kangavar County (Delphi and Analytic Hierarchy Process). The study population of the study was residents of target villages of brick kilns, brick kiln workers, kiln owners, and experts and specialists in this field, and 14 people were selected as samples based on the criterion-based sampling method. The data collection tool was semi-structured individual in-depth interviews and field notes, and the interviews continued until data saturation was reached. Content analysis and the seven-step Claise model were used to analyze the data, and the data were analyzed using descriptive statistics and in the (  ) (Expert Choice) software environment. Results: Based on the research results, in relation to the threats posed by brick kilns, three thematic categories were identified: A. Land use change (land removal from the production cycle, creation of water storage ponds, damage and destruction of secondary roads, and desertification), B. Vegetation change (reduction of fertile soil for plant growth, reduction of plant growth and drying, reduction of fodder required by livestock, reduction of plant photosynthesis, and reduction in the quantity and quality of plant products), and C. Land degradation (severe soil erosion, landslides, and soil impoverishment) was identified, and in relation to the lived experiences of participants from brick kilns, five clusters were identified: 1. Disease (lung problems, spinal problems, and boredom and depression), 2. Expansion of social connections (connections with different ethnic groups and greater connection with the people of the village), 3. Economic benefit (reduction of unemployment, income generation, and job creation), 4. Conflict of interest (conflict with kiln owners and conflict with organizations), and 5. Hard work (hard and exhausting work, becoming addicted due to hard work, and not continuing education due to exhausting work). Also, the use of government facilities and support in the field of accelerating the provision of infrastructure facilities for the creation of agricultural projects such as greenhouses, the correct implementation of agricultural land use conservation laws regarding the activity of brick kilns, and the use of deterrents in the field of preventing further destruction and informing the villagers about the environmental risks of brick kilns were, respectively, the most important or, in other words, the most appropriate solutions for the sustainable management of lands covered by brick kilns in Godin Rural District, Kangavar County.

  Humic acid is the active ingredient in humus, which is gray to dark brown in color. Humic acid macromolecules have a predominant aromatic characteristic and have a high content of functional groups such as phenolic, carboxyl and quinone, which leads to the surface charge and reactivity of this compound.This factorial experiment will be performed in a completely randomized design with three replications. Initially, humic acids will be extracted from five different organic sources (bovine manure, municipal waste compost, vermicompost, sheep manure, poultry manure) with 0.1 M NaOH. Extraction with distilled water will also be performed to compare the extraction with NaOH and to calculate the extraction efficiency. In the next step, the properties of the extracted humic acids such as spectroscopic absorption at different wavelengths, ash percentage, carbon content, nitrogen, hydrogen, oxygen and total sulfur with the elemental analyzer (Elemental Analyzer) and groups The factor will be determined with the FTIR device and the results will be compared. Then, a sample of surface layer calcareous soil (depth 0 to 20 cm) is prepared and after applying different concentrations of humic acids (four concentration levels, 0, 0.25, 0.5 and 1 g of humic acid per kg of soil) extracted from various sources, and will be incubated for 70 days. Finally, the availability of the three main consuming elements (nitrogen, phosphorus and potassium) will be determined at the end of the incubation period. After collecting the results, they will be analyzed using    software.Keywords: humic acid, nitrogen, phosphorus, potassium

   Abstract Purpose: today, the importance of strategic products such as oilseeds and especially rapeseed, has increased the necessity of paying attention to the role of effective factors on the improvement of the production value chain of this product. Accordingly, the purpose of this study has been the analysis of the value chain of rapeseed production and providing solutions to improve it.    Research Methodology: This research is an applied type and it has been done   with a combined approach(qualitative-quantitative). The study community consists 15 key informants in qualitative part. Data collection method was in the form of semi-structured interviews. In the quantitative part, data were collected using a questionnaire tool using two methods of survey(farmers N=130) and census(experts N=25).    Findings: The findings of this study showed that currently the rapeseed production value chain in Biston district includes 9 loops including rapeseed farmers, shopping centers, service centers, research centers, banks, supply and distribution of inputs. Tra  ortation, and insurance companies and most of them have been in unsuitable condition.   The first and most important challenge of this chain in Biston distric has been the shortage of machinery, especially harvesters, and   traditional operating system dominance, weakness in technical knowledge has increased production costs and negative profit margins for the producer loop. And reduced productivity of the chain.   Conclusion: all the loops in the value chain of rapeseed production have not achieved the expected performance in the studied dimensions and the effectiveness of the governing department by creating protections and constraints in policies and planning and monitoring how the activities are done is quite obvious. Therefore, it is necessary for the government and government institutions at the top and all actors in the chain to take a systematic look to optimize their actions in the chain and solve problems in the region. One of the achievements of this study was the identification of dysfunctional, missing and extra loops in the rapeseed production value chain in Biston district, which has not been addressed before.

Plants’ seeds are a natural storage organ that is considered by genetic engineers as an ideal target for the expression of recombinant genes. Therefore, controlling the expression of transferred genes in this organ is one of the most important steps toward the development of the molecular farming strategy. A practical solution for this purpose is to identify, isolate and use the seed-specific promoters in important commercial species such as rapeseed. Oleosin is one of the most abundant proteins in the seed proteome of rapeseed and its expression is controlled by highly spatiotemporal promoters. The promoter of this gene causes strong expression of the reporter gene such as GUS in embryonic tissue and seed endosperm. In this study, in order to apply and identify the regulatory elements in the Oleosin promoter, this sequence was isolated from the canola genome and cloned into the   K+ vector. Comparing the sequence of the cloned fragment with the sequences in the NCBI database showed that, this sequence has significant similarities with the two categories of identified sequences. One group is the Oleosin gene-like sequences and the other is the methionine sulfoxide reductase gene-like sequences. This means that this fragment is present in an intergenic region that justifies the bidirectional function of this promoter. Drawing the phylogenetic tree and calculating the genetic distance of the cloned fragment with these sequences showed that the genetic distance of the cloned fragment with the existing sequences for the Oleosin gene is much less than the methionine sulfoxide reductase genes. Sequence analysis of this fragment showed that this fragment contains a large number of regulatory elements in both sense and antisense strands such as TATA-box, RY element, prolamin-box and Skn-1 motif. Most of these regulatory elements were identified in the 400 terminal nucleotides of this fragment (the region corresponding to the promoter of the Oleosin gene), while its 540 primary nucleotides bear a striking resemblance to the CDS region of the methionine sulfoxide reductase genes. Further studies showed that the density of regulatory sequences in the sense strand (Oleosin gene promoter) was higher than in the antisense strand and many regulatory elements such as napin motif, pyrimidine-box, E-box, SEF3 and SEF1 binding sites were present only in the sense strand. This means that this promoter has a completely different function in expressing the two genes under its control so that most of the regulatory elements that are present in the sense strand (but not in the antisense strand) are found in seed-specific promoter

Volatile organic compounds (VOCs) are secondary substances of probiotic bacteria whose role in plant growth and control of plant diseases has been proven. Bacterial volatiles have high vapor pressure and react rapidly in the environment; the purpose   of this study was to formulate volatile compounds by modeling from other sciences. Initially, a greenhouse test was carried out to control the disease caused by Gaeumannomyces tritici. The highest reduction of disease than the control was observed in benzothiazole and acetone treatments, which reduced the disease index by 60.9 and 57.4%, respectively. Sodium alginate, gum arabic-maltodextrin and iron nanoparticles were used as carriers. Electron imaging was used to ensure the appearance of the formulations prepared, the formulations being spherical and with small cavities, allowing the compound to escape with controlled release. According to spectrophotometric results, these carriers were able to hold volatile compounds for up to 14 days and FTIR was also used to confirm the volatile confinement in high carriers, which also confirmed the confinement of volatile compounds.

  AbstractSince the late 1980s, Micro financial institutions have been given special prominence as one of the most effective and efficient strategies for financial development or in developing countrie's development and the number of these institutions increased sharply. The history of micro-credit funds for rural women Iran goes to the year 1378 returns. Designing a micro credit Fund in Iran Using Grameen Bank Bangladesh Experiences "Pattern of   group savings and lending" as a successful model in rural community and after localization by experts of Research Center of Ministry of Jihad – e – agriculture, a pilot experiment was carrued out in two provinces in Mazandaran and kermanshah. After the success of the program implemented in Stelen   Mazandaran province, the socoal development approach has been expanded since the beginning of the year. From year 1380   the development of its expansion in the country took a social approach. Also fram about 87 year, Representation of the United Nations Office in Iran with the aim, Sustainable human development (Deprivation and job creation) transmitted and promoted suitable   in ternational development ideas and solutions. The goals of micro credit programs, increase the income of poor by creating self – employment, providing educational services for optimal use of resources and empowering rural women has been through job creation.
