What must be deducted along with gross income to correctly assess agricultural income?

Correct answer: Costs such as seed, manure, labour, rent and loan interest

Gross agricultural income is the total money received from selling crops, animals, or other farm output before expenses are removed. It does not show how much the farmer actually keeps. To calculate net income, the necessary production and finance costs must be deducted. These may include seeds, manure or fertiliser, wages, rent, irrigation, transport, and interest on loans. The exact list can vary, but the principle is that income must be compared with the cost of earning it.

The names of a field, village, or season are useful for records but are not expenses and cannot be deducted to find profit. After subtracting relevant costs from gross income, the remaining amount represents the farm's net income. Therefore option D is correct because it lists real costs that reduce the amount available to the farmer. This distinction helps prevent confusing total sales with actual earnings.
