Economic growth as an important indicator has always considered by policy makers. In presence of production inputs constraints, the most appropriate way of growing each sector is increase of productivity. In the agricultural sector due to several risks that farmers face as a result of activity in an open environment, productivity is also affected by these risks. Because of the importance of agriculture in the economy and food security, some strategies should be devised to reduce the risk that mechanization and infrastructure development for reducing the risk of cropping, expansion of insurance and crop diversification are taking place in this category. Hence, the present study has measured total factor productivity of agronomy and horticulture subsectors by using the Tornquist-Theil Index for years 1974-2007 and then by estimating a regression model, influence of the above factors on productivity has been evaluation. The average of total factor productivity growth of agronomy and horticulture subsectors was 0.96 for this period. The results showed positive effect of crop diversification and insurance on productivity and also, it will be reduced by excessive use of tractor.

Because of implications for improving agricultural students’ learning and finally problem solving, creativity and employability, nowadays the modern teaching methods are a matter of great concern. Therefore, this study explored the effect of teaching methods on learning of agricultural students in Campus of Agriculture and Natural Resources, University of Tehran. The study was carried out during a semester for metrology and climatology course. 75 students enrolled in the course were assigned to treatment and control groups. The experimental group was tough using the constructivist teaching method while the control group was taught using the traditional teaching method. Experiment was implemented for total of 20 hours over 12 weeks. The instruments used for measurement of learning in higher levels thinking and lower levels thinking were as follows, mid-term and final- term tests applying open-ended (free response) questions. The content validity of the tests was approved by several of teachers of metrology and climatology. The reliability of tests was measured through the examiners reliability based on scoring rubric method which respectively calculated as 0.997 and 0.991 for mid-term and final exams. The covariance analysis results revealed that the teaching methods had effect on total grades of the students at the semester. A further exploring of findings showed that there was no significant difference in the learning of two groups when it was separated based on levels of thinking and also when it was separated based on the mid-terms and final- term tests.

In this study the consumption behavior of Iranian urban households is analyzed for the eight main food commodities groups including cereal and its products, meat, milk and its products and eggs, fruits and vegetables, edible oils and butter, beverages, grains and nuts over 1974-2007. In this context, the flexible demand models such as Quadratic Expenditure, Rotterdam, Almost Ideal Demand System, Quadratic Almost Ideal Demand System, Inverse Almost Ideal Demand System (IADS) and CBS were estimated by seemingly unrelated regressions. Based on comparing the statistical tests and econometric criteria, the IADS was selected as the best model. Results showed that among the food items, dairly and meat have the least and highest quantity elasticity, respectively. The scale elasticities of meat and nuts were lower than those of other groups, which suggest that these goods are being luxurious.
