Agriculture is the most important sector of the Sri Lankan economy. Even though its contribution to the gross domestic product declined substantially during the past 3 decades (from 30 percent in 1970 to 21 percent in 2000), it is the most important source of employment for the majority of the Sri Lankan workforce. Approximately 38 percent of the total labor force was engaged in agriculture in 1999. In the subsistence sector, rice is the main crop and farming rice is the most important economic activity for the majority of the people living in rural areas. During the last 5 decades the rice sector grew rapidly and output more than tripled, reaching the highest ever output of 2.9 million metric tons in 1999. Increases in the area under cultivation, and improved productivity due to the modernization of agriculture are the main reasons for an increase in production. The rehabilitation of Sri Lanka's extensive ancient irrigation network and massive new investment in construction and maintenance of irrigation infrastructure led to a large increase in the area under rice cultivation. Between 1960-2000, the area used to grow rice increased 6 times to 546,249 hectares. The modernization of farming methods, such as the use of high-yielding seeds, tractors, and chemical fertilizers also led to increased productivity in the rice sector. Between 1960-1999, rice yield per hectare doubled from 1,877 kilograms to 3,672 kilograms. In addition to rice, various other food crops are produced for local consumption. They include yams, pulses, grains, vegetables, and fruits. Most of these crops are cultivated in family gardens, except for potatoes and sugar. Sugar cane is cultivated in the dry zone, and Sri Lanka produces only 15 percent of what it consumes domestically.Read more: https://www.nationsencyclopedia.com/economies/Asia-and-the-Pacific/Sri-Lanka-AGRICULTURE.html#ixzz6vrxdyz7V
