The correct answer is: All of the above.
Agricultural extension services in Manipur play a role in disseminating knowledge to farmers, demonstrating improved practices, and providing training.
Disseminating knowledge to farmers is important because it helps them to learn about new agricultural technologies and practices that can improve their yields and incomes. Agricultural extension workers can do this by conducting field demonstrations, holding workshops and training sessions, and providing farmers with written materials.
Demonstrating improved practices is another important role of agricultural extension services. This involves showing farmers how to use new technologies and practices in their own fields. This can be done by conducting field demonstrations, providing farmers with hands-on training, and helping them to troubleshoot any problems they may encounter.
Providing training is also an important role of agricultural extension services. This involves teaching farmers about the latest agricultural technologies and practices. This can be done through formal training programs, workshops, and field days.
Agricultural extension services play a vital role in helping farmers to improve their livelihoods. By disseminating knowledge, demonstrating improved practices, and providing training, agricultural extension workers can help farmers to adopt new technologies and practices that can lead to higher yields, increased incomes, and improved food security.
