One of the ways of improving the marketing of agricultural produce is by

Step 1: Analyze the question The question asks about improving the marketing of agricultural produce. Marketing covers how farm produce is bought, sold, stored, priced, and distributed after harvest. So we need the option that deals with the selling and distribution side, not the production side.

Step 2: Explain the concept Agricultural marketing involves grading, storage, transportation, pricing, and finding buyers for farm produce. Problems in this area include price fluctuations, middlemen exploiting farmers, and poor storage. Institutions like commodity (agricultural) marketing boards were set up to solve these problems. They buy produce from farmers at guaranteed prices, stabilise prices, store produce, and sell it locally and abroad. Examples in Nigeria include the old Cocoa Marketing Board, Groundnut Marketing Board and Palm Produce Marketing Board.

Step 3: Evaluate each option

• A. Reviewing the land tenure system: This affects access to land, which is a production issue, not marketing.
• B. Ensuring even distribution of farm inputs: Inputs such as fertilizers and seeds relate to production, not marketing.
• C. Embarking on irrigation farming: This increases output and allows off-season farming. Again, it is about production.
• D. Establishing agricultural marketing boards: These directly handle buying, pricing, storage, and sale of produce. This is a marketing improvement.

Step 4: Answer The correct answer is D. Establishing agricultural marketing boards.

Tip: In Economics questions on agriculture, first decide whether the question is about production (land, inputs, irrigation, labour) or marketing (boards, storage, transport, pricing). Match the option to the right category, and the answer becomes clear.
