Optimum seed rate of onion to get desired plant population (kg/ha):

✅ Explanation:
The optimum seed rate for onions typically falls within the range of 8-10 kg/ha. This range ensures a sufficient number of plants establish themselves, leading to a desirable plant population and maximizing yield potential.

• Several factors influence the ideal seed rate, including:
-Seed quality: High-quality seeds with good germination rates require a lower seed rate compared to seeds with lower germination percentages.
-Variety: Different onion varieties may have varying seed sizes and germination rates, impacting the required seed rate.
-Planting method: Seed rates might differ slightly depending on whether onions are directly seeded or transplanted.
-Soil conditions: Well-prepared, fertile soil may require a slightly lower seed rate than poor-quality soil.
Using the 8-10 kg/ha range generally strikes a good balance, ensuring enough plants without overcrowding, which can lead to competition for resources and smaller bulbs.
