For this purpose, the integrated model of acceptance and use of technology was used. The statistical population of the research was the adopters and non-adopters of canola cultivation in the country. All adopters (35 people) and 118 non-adopters who were selected by random sampling with appropriate distribution were studied and investigated using the survey method. The data collection tool was a researcher-made questionnaire, which was developed based on the components of the theory, and its validity was revised and confirmed by a panel of academic experts. To measure the reliability of the questionnaire, a pilot study was conducted outside the statistical population, and the Cronbach's alpha coefficients (0.67 to 0.93) obtained indicated the satisfactory reliability of the questionnaire. The collected data were loaded into SPSS21 statistical software and related statistical tests were taken. The findings of the research showed that the average score of "facilitating conditions", "expected performance" and "expected effort" in two groups of farmers showed a significant difference. Also, the findings from the discriminate analysis indicated that "facilitating conditions" had a greater share in the discrimination of the two groups of the farmers. Meanwhile, the results of the path analysis showed that "social influence" and "expected performance" had the greatest effect on the willingness to accept, and "facilitating conditions" had the greatest effect on the adoption behavior of canola cultivation.

2 - Comparison the effect of sulfur on yield and micro elements uptake in oilseed crops and forage plants The effect of sulfur on yield and nutrient uptake in oilseed crops and forage plants
Reyhane Dehghan Ali Akbar Karimian Somaye Ghasemi Malihe AminiBackground and Objective: Today, due to high prices and destructive effects of uncontrolled use of chemical fertilizers on the environment and the quantity and quality of agricultural products, use of sulfur as a micro element and also acidifying agent in soil is too im MoreBackground and Objective: Today, due to high prices and destructive effects of uncontrolled use of chemical fertilizers on the environment and the quantity and quality of agricultural products, use of sulfur as a micro element and also acidifying agent in soil is too important and necessary. Material and Methodology: In order to evaluate and compare the effect of sulfur on yield and the ability to micro elements absorption with oilseed safflower, canola, corn and fodder plants sorghum and pigweed in a calcareous soil a factorial experiment was conducted based on randomized complete blocks design with three replications. The experimental factors were contain sulfur fertilizer in two levels (without application and consumed 500 kilograms per hectare). Findings: Results showed that the use of sulfur caused a significant increase in wet and dry weight in all plant species and the maximum increase was observed in corn and sorghum species. The use of sulfur causes significant increase absorption of iron and zinc in roots and shoots of all species of plant.Discussion and Conclusion: Among the oilseeds, the effect of sulfur application on corn and canola was higher than safflower and the sorghum forage had better performance than the pigweed.

3 - A review of some studies on the effects of various irrigation methods on some oilseeds

Oil consumption in Iran has increased in recent years due to population growth and per capita consumption, so that considering the per capita consumption of 14 kg, about 750,000 tons of oil is needed annually. However, less than 10% of this oil is produced domestically. Due to this issue, oil production through rapeseed cultivation has been considered in recent years. Drought is a threat to the successful production of crops worldwide. Drought occurs when a combination of physical and environmental factors causes internal stress in a plant and reduces production. Water stress has a negative effect on many plant processes, including photosynthesis, evaporation, accumulation and allocation of precursors, and causes a significant reduction in crop production. Therefore, one of the ways to maximize water use efficiency and increase yield per unit of water consumption is low irrigation, in which the crop is subjected to water stress at a certain stage of development or throughout the development season. On the other hand, the positive effects of potassium in increasing the resistance of plants to dehydration stress have been reported by researchers. Manuscript profile -

The amount of soil moisture for optimal growth of each plant should have an optimal level that getting more or less than this optimal level, plant growth decreases and soybean yield is affected by the total number of pods per shrub, the number of seeds per pod and the weight of each seed To investigate the effect of drought stress on physiological traits of soybeans; Drought stress reported a significant reduction in the amount of the photosynthesis and grain yield Increasing irrigation and rain water consumption efficiency is affected by the correct application of chemical fertilizers, especially nitrogen. In addition, nitrogen deficiency after water shortage is the most important factor in reducing crop production, especially cereals. Among the yield components, the number of pods per node was significantly affected by nitrogen fertilizer, so that by increasing the amount of nitrogen, the number of pods per node was increased. In general, optimizing water and fertilizer consumption in crops, especially oilseeds, can increase agricultural production as well as save water resources. Manuscript profile -

5 - Response of seed quantity and quality of promising winter rapeseed genotypes to terminal water limitation

The factorial experiment based on randomized complete block design was laid out in three replicates including two factors of genotype (six winter rapeseed genotypes called Karaj2, Karaj3, KS7, L5, L146, L210) and water limitation (three levels of water deficit stress viz. full irrigation IW1, irrigation withholding from anthesis IW2 and irrigation withholding from seed set IW3). Imposing water restriction from anthesis caused more loss of silque and seed number and final yield. The least loss of seed yield obtained from L5 and L210 genotypes under drought stress during anthesis. The greatest and lowest fall in seed germinability were recorded in L146 under drought stress from anthesis and L5 and L210 under the same stress level, respectively. Under water limitation from anthesis, the least increase of seed electroconductivity was observed in genotype L5. The greatest length and vigor index of seedling was observed in genotypes L5 and L210 under irrigation withholding from flowering. In general, occurring terminal drought stress especially during anthesis of rapeseed caused significant drop in seed production, both quantitatively and qualitatively. On the other hand, genotypes L5 and L210 had the best yield under stress condition and would recommended for introducing to breeding program of drought stress tolerance. Manuscript profile -

This research was carried out as a completely randomized block design with 9 treatments in 3 replications in the research farm of the Iraqi Mahalle. In each plot, 5 rows were planted, the distance between rows was 40 cm and the distance between replications was 3 meters. The studied traits included plant height, harvest index, seed yield, thousand seed weight and biological yield. The results obtained from this study showed that the treatment with humic acid + micronutrient, control and control + irrigation fertilizer + humic acid fertilizer had the highest biological performance, and the lowest biological performance was related to humic acid irrigation fertilizer and irrigation fertilizer + micronutrient. Also, the weight of one thousand seeds in the control group and the eighth treatment was significantly lower compared to other treatments. These results show that the use of micronutrient fertilizers and humic acid could significantly increase the weight of a thousand seeds. Finally, the seed yield was significantly higher in control, control + humic acid seed, and control + humic acid seed + micronutrient than other treatments. These results show that application of humic acid has better effects on grain yield than other treatments. Manuscript profile
