The increasing trend of agricultural waste, considering population growth and increased agricultural production, has become a serious challenge for many countries. In order to avoid unsustainable changes in the consumption pattern of these resources, it is essential to employ proper planning and suitable strategies to prevent long-term damages. To address this issue, this research has prioritized various strategies for energy production from agricultural waste using SWOT analysis. The Analytic Network Process (ANP) algorithm has been utilized to quantify the weights and effects of the strategic factors, considering their interdependencies. The best strategy selection has formed the four-level network of primary and secondary factors in the SWOT matrix and proposed strategies. The algorithm's results indicate that the strength factor holds the highest weight of 0.698, followed by the threat factor with a weight of 0.632 in the second rank, while the weaknesses and opportunities have weights of 0.263 and 0.180, respectively, in subsequent ranks. Furthermore, the evaluation of weight coefficients for the ten proposed strategies reveals that the strategy of developing the cultural infrastructure for bioenergy has the highest weight of 0.1356, followed by the mechanized harvesting of agricultural waste with a weight of 0.1188 in the second rank, and the development of bioenergy exports with a weight of 0.1095 in the third rank.

The increase in the area under greenhouse cultivation in Tehran Province is important for the increase in production and for its substantial social importance due to the preservation of agricultural land, especially small farms. In addition, the increase in the number of greenhouses producing summer crops in this province attracts idle capital to the agriculture sector thereby creating jobs. The present research used stratified cluster sampling for selecting the counties of interest having the largest areas under greenhouse cultivation of summer crops in Tehran Province in order to select the producers in each greenhouse size range (taking into consideration the number of producers in it) via random sampling in which a table of random numbers was employed. Fifty-five greenhouses were selected in the province, 22 greenhouses producing only cucumbers, 15 greenhouses producing cucumbers and tomatoes, and 18 greenhouses producing cucumbers and bell peppers. The results of the cost-benefit analysis (CBA) showed that production of greenhouse summer crops was economically justified for greenhouses larger than 3000 m2 in surface area. However, the trend in the profitability of activities was a rising one for greenhouse surface areas of up to 4500 m2 beyond which a falling trend was observed. Finally, it was suggested that the Jihad Agricultural Organization of Tehran Province refuse to issue an establishment license for the production of greenhouse summer crops in areas lower than 1500 square meters and provide the necessary incentives for the production of greenhouse summer crops in Tehran, in areas between 5000 to 7500 square meters.

In order to find how different types of weeders (powered and non-powered) are working in controlling weeds of peddy lands in which two rice cultivars, Deilamani and Hassansaraei, were grown, a field experiment was conducted in 2017-2018. This study was performed as a factorial experiment with cultivar in two levels, Deilamani and Hassansaraei, and weeding method in five levels including manual motor weeding, using single-row, two-row, three-row weeders, and control. The experiment was performed in a randomized complete block design with three replications. Evaluation parameters in this study included field capacity, field efficiency, weeding efficiency, weed charateristics, plant growth charateristics and the rate of damaged plants. The results showed that the highest (91.91%) and lowest (91.33%) efficiency were obtained when single-row powered weeder and three-row powered weeder, reaspectively, were used. In terms of field capacity, the single-row powered weeder was on the top of the list with 0.198 ha.h-1, and the non-powered manual weeder was at the bottom of the list with 0.0096 ha.h-1. In terms of field efficiency, the single-row powered weeder was on the top of the list with 78.22%, and the non-powered manual weeder was at the bottom of the list with 65.53%. The results obtained from this study indicated that the single-row powered weeder was recognized as the best weeder in controlling the rice weeds where Deilamani and Hassansaraei cultivars are growing.
