This quest  is called 'Spring Planting', for Adventurers levels 181 to 241. This is a SEASONAL quest. It is available for a limited time. Lord Agrippa is the master in charge of this quest. The season of planting is upon us. The ground has almost thawed completely from the past winter. This is the time to determine what crops we will grow this year. Gather information regarding planting techniques, seeds and the fruit of those seeds. This will require careful planning, as some seeds grow faster than others. Complete this great task for me and I will reward you greatly. Our harvest this year depends on your research. Upon successful completion of this quest you can receive: *Up to 50 quest points, 4 practice points, 45,000 experience points, 0 build points, and 20,000 gold pieces. You have 400 Alyrian minutes remaining to complete this quest. Spring Planting consists of: Phase 1: Visit A peasant farmer. Phase 2: Visit An experienced farmer. Phase 3: Visit Broshed. Phase 4: Recover a wood and iron spade. Phase 5: Recover an iron rake. Phase 6: Recover a rose bush. Phase 7: Recover an aloe vera branch. Phase 8: Recover a bright, shiny red apple. Phase 9: Recover a carrot.
The last phase is to recover a carrot, which you get from carrot seeds. Which takes a while to germinate. (longer than the duration of the quest itself.)
The problem lies therein.

This tiny black seed, if planted in the ground and tended properly, will eventually grow into a nutritious and delicious carrot. These orange vegetables are an essential part of a balanced diet, and will certainly help your vision if eaten regularly. Many families in New Rigel grow their own food in their gardens to help keep the cost of groceries down.
Also: The carrot itself doesn't last very long, so it's not like one can just hoard these beforehand D:
