  1. روند تحقيقات در مهندسي ماشينهاي كشاورزي Research Trend in Farm Machinery Engineering

  2. Scientific Agriculture • By the 16th century, population was increasing in Europe, and agricultural production was again expanding. • By the late 1800s, steam power was frequently used to replace animal power in drawing plows and in operating threshing machinery. • Science and technology developed for industrial purposes were carried over into agriculture, eventually resulting in the agribusinesses of the mid-20th century. • In the 20th century steam, gasoline, diesel, and electric power came into wide use. • Industrial Agriculture introduced

  3. Recent Changes. • From a high of 6.8 million farms in 1935, the total number declined to 2.1 million in 1991. • Average farm size in 1935 was about 63 ha (about 155 acres); in 1991 it was about 189 ha (about 467 acres). • در آمريكا براي يكپارچه سازي اراضي چگونه مكانيزمي بكار رفته است؟ آيا براي كشور ما راهگشاست؟؟ • Agricultural Mechanization introduced • به نظر مي رسد مقدمه مكانيزاسيون يكپارچه سازي است • آيا يكپارچه سازي مكانيزاسيون را سبب شده يا مكانيزاسيون يكپارچه سازي را بدنبال داشته است؟

  4. 1960 - 1980 • No-tillage agriculture popularized • More farmers used no-till or low-till methods to curb erosion

  5. 1980 -1990 • More farmers began to use low-input sustainable agriculture (LISA) techniques to decrease chemical applications • Organic Farming introduced • Agricultural Automation introduced

  6. Agricultural Automation • Precision agriculture and information technology • Site-specific management: the application of information technology to crop production • Possible adoption of precision agriculture for developing countries at the threshold of the new millennium • The impact of farm management on value of management information systems • Ethics in computer software design and development • Instrumentation and control • Computers and electronics in postharvest technology • Introduction of electronics into milking technology • Developments in indoor sustainable plant production with emphasis on energy saving • Integrated control of agricultural tractors and implements • Biosensors developments and potential applications in the agricultural diagnosis sector • Modelling

  7. Outlook for agricultural engineering in Developing countries • shift the historical emphasis from 'on-farm mechanization' to the development and application of new innovations using on-farm agricultural automation AND off-farm industries
