Concept:Subsidies on farm inputs lower production costs, which encourages farmers to increase their output.
Explanation:Agricultural output is largely influenced by the cost and availability of farm inputs such as fertilizers, improved seedlings, and pesticides.
When the government grants subsidies on these inputs, it reduces the purchase price paid by farmers.
This makes modern farming tools more affordable and accessible to small-scale and commercial farmers alike.
With cheaper inputs, farmers can cultivate larger areas of land and apply better farming techniques.
The result is an increase in total agricultural production in Nigeria.
Buffer stock programmes mainly help to stabilize prices after harvest, not to raise output directly.
An embargo on food imports can create a market for local produce, but it does not directly increase the quantity farmers produce.
Placing farmers on a monthly income is not a production incentive and would not expand farm output.
Therefore, granting subsidies on farm inputs is the policy that directly boosts agricultural output.
