Why is plant observation done in agriculture?

Answer and explanation

Correct answer: To know growth pest and disease condition

The direct answer is A: plant observation is done to know the growth of plants and to detect pests and diseases. Plant observation means looking at the crop regularly and carefully. A farmer checks whether plants are growing properly, whether leaves are changing colour, whether insects are eating them, and whether spots, wilting, or other disease signs are appearing. Step by step, regular observation helps the farmer notice a problem early; early knowledge allows timely watering, nutrient management, pest control, or disease treatment; timely action can protect yield and quality. Option A is correct because it directly describes the purpose of observing a crop. Option B is wrong because observation does not mean selling the crop immediately; sale is a marketing decision made later. Option C is wrong because observing plants is not done to close the field. Option D is wrong because it has no connection with crop monitoring or plant care. A useful exam cue is: observation means checking crop health, growth, pests, and diseases before taking care measures.
