The marketing functions listed are activities involved in getting agricultural products from farmers to consumers.
"Planting of crops" is not a marketing function because it involves the actual production of agricultural goods rather than the distribution and sale of those goods. The planting of crops is part of the production process and occurs before the marketing functions begin.
To summarize, marketing functions include activities such as buying agricultural commodities, transporting farm produce, financing agricultural production, and storage of farm produce, but do not include planting of crops.
