Rice cultivation has increased markedly since freedom, although in the late 1980s yields remained well below those of the major rice-producing countries. Much of the improvement came in the late 1970s and 1980s. Rice remained a smallholder's crop, and production techniques varied according to region. In some villages, it was still sown by hand, with harvesting and threshing often engaging the entire family, plus all available friends and relatives.

The importance of crops other than tea, rubber, and coconut increased after 1970, and in 1986 they accounted for around 51% of agricultural output. There was a substantial increase in of minor food crops, including soybeans, chilies, and onions, all of which are grown as subsidiary crops on land irrigated by the Mahaweli project. In the 1960s and earlier, vegetables were imported from India in large quantities, but in the 1980s the island's import requirements were much smaller. Spices, including cloves, nutmeg, cardamom, and pepper, also registered large gains in the 1970s and 1980s. A large proportion of the spice output was being exported in the 1980s. A wide mixture of tropical fruits, including mangoes, pineapples, plantains, and papayas, also were grown; most were consumed in the domestic market. Sugar output increased in the early 1980s, although in 1986 it still accounted for only 11% of the domestic consumption. The development in sugar took place contempt the problems of the state-run sugar mills and their associated sugar lands in Eastern Province, which have been disrupted by civil strife. Two new mills in Western Province accounted for the increase in production, and in early 1988 the outlook for further development was good.The animal life of Sri Lanka is various and includes many species that may be in danger of extinction, such as the cheetah, leopard, several species of monkey, and elephant. The island also contains numerous species of birds and reptiles.
