The frequency of irrigation for onion crops is a critical factor influencing bulb development and overall yield. Providing the correct amount of moisture at each stage of growth ensures optimal plant health and minimizes the risk of disease or stress. Overwatering or underwatering can negatively impact bulb size and quality.
Appropriate watering schedules contribute to the efficient use of water resources, reducing potential waste and promoting sustainable agricultural practices. Historically, farmers have relied on observation and experience to determine the correct irrigation amount. Modern methods incorporate soil moisture sensors and weather data to improve precision and efficiency in watering onion plants.
