An agricultural extension service
offers technical advice on agriculture to farmers, and also supplies them with the necessary inputs and services to support their
agricultural production. It provides information to farmers and passes to the farmers, new ideas developed by agricultural research
stations. Agricultural extension programmes cover a broad area including improved crop varieties, better livestock control, improved
water management, and the control of weeds, pests or plant diseases. Where appropriate, agricultural extension may also help to build
up local farmers' groups and organizations so that they can benefit from extension programmes. Agricultural extension, therefore,
provides the indispensable elements that farmers need to improve their agricultural productivity.
