The blank refers to the things a farmer should do to help plants grow fast and be productive. The farmer must provide adequate water, because plants need it for photosynthesis and nutrient transport. He must also ensure enough sunlight exposure, since sunlight is the primary energy source for plant growth. In addition, farmers should use fertilizers or compost to supply nutrients such as nitrogen, phosphorus, and potassium. Protecting crops from pests and diseases through proper care is also important. Combining these practices—watering, giving sunlight, enriching soil, and protecting from pests—creates an environment where plants can thrive. These basic farming actions make crops healthier, produce bigger yields, and ensure food security for the community.
