उत्तर
In rainy conditions, there is a very high chance of lightning striking the earth. So, the farmer, by putting an iron stake into the ground while working in the field in rainy conditions, makes sure that he and his crops remain safe in case lightning occurs. This is because the iron staff will be more prone to lightning than the crops and his body because of the iron staff being tall and metallic in nature. Thus, the electric charges from the clouds will flow to the ground through the staff without affecting the plants in case of lightning during rainy weather.
