Answer:
supply curve to the right. 
Explanation:
A drought decreases the supply of agricultural products, which means that at any given price a lower quantity will be supplied; conversely, especially good weather would shift the supply curve to the right. Drought refers to a period characterized by little or no rainfall in a geographical location over a specific period of time. When there's a drought, the production of agricultural products will be very much affected, thereby causing a decrease in the quantity of farm products. 
On the other hand, a good weather would cause an increase in the quantity of farm products and as a result of this, the supply curve would shift rightward because there's enough product to meet the customer's demands or needs.
