The most important factor that determines the rate of agricultural development is the adoption of viable agricultural research findings. This means that for agriculture to develop at a significant rate, research must be carried out to find out new ways to improve agricultural practices, and the results of such research must be made available and adopted by farmers. This includes improved crop varieties, better pest and disease management strategies, and new farming techniques that can increase productivity and efficiency. The quantity of herbicides used, number of machinery available, and number of people involved in agriculture can all play a role in agricultural development, but they are not as important as the adoption of viable research findings.
