Bangladesh is predominantly an agricultural country, where agriculture sector plays a vital role in accelerating the economic growth. Agriculture remains the most important sector of Bangladeshi economy, contributing 19.6 percent to the national GDP and providing employment for 63 percent of the population. A National Agricultural Census report has said Bangladesh is currently home to 16.5 million farmer families. The report also highlighted the fact that there over four million landless farmers, with near 6.8 million farmers cultivating other people's land. To help the farmers and improve in agricultural sector, we design and develop a web based application "Smart Farming System". Farmers of Bangladesh can learn and share various knowledge and problem facing during farming through this system. Farmers can acquire information around various diseases and resolver on their problems. They can get support in various agricultural activities, by the help of the consultants and doctors through the "Smart Farming System". To develop this system we used HTML5, CSS, Bootstrap, and JavaScript. In addition, the PHP framework is used to manage the MySQL database. In testing phase, we tested it with a community based social media on Facebook and its work great with expecting output, peoples are expecting these services to be interesting.
