The current research was conducted with the aim of identifying and prioritizing strategies for increasing the productivity of agricultural mechanization in wheat production. This research was based on a mixed method and in two phases, qualitative and quantitative. In this research, the integrated approach of SWOT, PESTEL and AHP has been used. First, by using SWOT analysis in the framework of PESTEL, the strengths, weaknesses, opportunities and threats of wheat production mechanization and strategies to increase the productivity of mechanization of wheat production were identified . Then the process of hierarchical analysis was used to calculate the weight and importance of each of the criteria and strategies. In order to collect data, written sources, interviews and paired comparison matrix questionnaires were used, and the participants in the research were university and organizational experts in the field of agricultural mechanization. The results showed that although mechanization in wheat production has many strengths, the weaknesses are more effective. Also, despite the fact that mechanization has many threats, but the opportunities are more effective. Therefore, the officials should try to make the most of the available opportunities by reducing the weaknesses. As a result, from the expert's point of view, conservative strategies were prioritized in terms of importance. Increasing the technical efficiency, production of suitable technologies for all types of operating systems, improvement and modernization of the system, use of irrigation methods under pressure and create transformation in the process of land preparation , conservative strategies were suggested in this research.

Given the vastness of the country's border area and the climatic diversity of the crop and garden various regions, it is an undeniable necessity to achieve a suitable cultivation pattern that can maximize the utilization of factors and institutions of production, especially the water-limiting factor. The main question in this study is that considering the current situation in horticulture in Qazvin province, what parameters emphasize the optimal conditions for determining the cultivation pattern and allocating inputs in different orchards. For this purpose, in this study, first, the relevant technical, environmental, social and economic indices and criteria that have been presented in various research sources were examined. Then, using multi-criteria decision making methods, a composite index of the mentioned indices was presented. In this study, a simple two-step random sampling method was used. In this research, in order to present a suitable pattern for cultivating horticultural products from the ideal planning method using Lingo 17 software was used. According to the results of the model, in the case of phosphate and potash fertilizers, the consumption reduction was observed to be 9.5% (above the ideal level), but in the case of nitrogen fertilizer, the consumption was reduced by 8%. In the case of the three ideals of reducing the consumption of herbicides, insecticides and fungicides, excessive success was observed, i.e. a decrease in consumption of 4.5, 5.7 and 8 percent, respectively. Due to the abundance of water resources in this area, in the case of 12 ideals related to water reduction, too much success was observed, i.e. a one percent decrease in water consumption per month. The results show that the application of ideal planning method in optimizing goals and allocation for each product provides more logical results than single-objective models.

High water consumption and the cost of labor in rice transplanting method is the reason for growing tendency of farmers to Dry-bed seeding of rice in Iran. High consumption of seed and inadequate specialized machines are the problems in rice dry-bed seeding. At present rice dry-bed seeding is done with traditional drill seeder with more than of 90 kg/ha seed consumption. While planting one seed in hole with a 20×20cm planting pattern in dry-bed seeding can reduce seed consumption to 5 kg/ha. This research was conducted for fabrication and laboratory evaluation a special seed plate for rice dry-bed direct seeding with pneumatic planter. Design parameters of Seed plate were included six plate shapes and three seed hole diameters. Seed plate shapes included traditional plate without groove and five groove shapes on plate, including three trapezoidal grooves with wall angle of 30, 45 and 60 degrees and two semicircle grooves with the aperture opening 2 and 3mm and three seed hole diameters 1.2, 1.3 and 1.5mm at the three levels of vacuum pressure 40, 50 and 60 milibar compared in a completely randomized design in a factorial experiment with three replications. Indices were, seed number per hole, miss index, over index and precision of feeding index. The results showed that creating the groove on the seed plate resulted higher seed cell covering and reduced miss and over index. New grooved plates had higher precision of feeding and lower miss index than conventional seed plate. By increasing the vacuum pressure and the diameter of the seed hole, miss index decreased and over index and seed number per hole increased. By increasing the angle of the walls of the trapezoid grooves and aperture of the semicircle grooves miss index reduced and over index and seed number per hole increased. In general, the results of laboratory evaluation Showed that for direct seeding of rice in dry-bed condition with pneumatic planter, using the seed plate with trapezoidal groove wall angle of 45 degrees and a diameter of hole 1.2 mm and vacuum pressure 50 mbar were better than others.

Iranian saffron is produced mainly in the provinces of Khorasan-e Razavi and Khorasan-e Jonoobi and is a strategic product of the agricultural sector. The high demand in the global market for saffron provides employment opportunities. Increasing production by improving mechanization methods at the various stages of production is the major challenge. The research format of this study was applied-development and the method was a cross-sectional survey. The SWOT model of strategic planning was the most important model for determining the strengths, weaknesses, opportunities, and threats of mechanization in saffron production. These were identified and evaluated and the best strategy for the development of mechanization was determined. The results showed that the sum of the final scores of the internal matrix factors (strengths and weaknesses) was 2.73. This indicates that the strengths were greater than the weaknesses. The matrix of external factors (opportunities and threats) had a total score of 2.67, which indicates that the current situation can be strengthened in the face of threats and opportunities with an appropriate strategic response. An aggressive strategy is best for improvement and development of farm mechanization in the Khorasan provinces. The superior strategies were determined using the quantitative strategic planning matrix (QSPM).
