Discover essential facts about optimal irrigation practices for pea crops, including timing, methods, and impact on growth. This quiz covers key aspects to help ensure healthy peas and efficient water use.
During which growth stage do peas need the most careful irrigation to maximize yield and pod formation?
Explanation: The flowering and pod filling stage is critical because water stress here can significantly reduce pod set and seed development. While seedling emergence needs water too, it is less sensitive than flowering. Irrigation during late maturity or after harvesting has minimal benefit, as plants require less water at these stages.
Which observable sign on pea plants suggests it is time to irrigate in the absence of recent rainfall?
Explanation: Wilting leaves, especially at midday, indicate water stress and the need for irrigation. New shoots suggest healthy growth, not a need for water. Yellowing lower leaves can be natural aging rather than drought. Fully dried pods mean the plant is at harvest, past irrigation requirements.
Among common techniques, which irrigation method is considered water-efficient and gentle for pea fields?
Explanation: Drip irrigation delivers water directly to roots, reducing waste and foliar diseases. Flood irrigation uses more water and increases the risk of fungal problems. Overhead sprinklers can wet foliage unnecessarily, while submergence irrigation is not suitable for peas as it can harm their growth.
If rainfall is absent and soil drains well, how frequently is irrigation usually recommended for actively growing peas?
Explanation: Irrigating once every 7–10 days maintains optimal soil moisture without overwatering. Daily irrigation can lead to waterlogging. Only irrigating twice a season or at harvest misses critical moisture periods and can limit yield.
Overwatering peas can lead to which significant problem affecting plant health and yield?
Explanation: Too much water can create conditions for root rot and opportunistic fungi to thrive, harming pea roots. Overwatering does not improve drought resistance, speed up pod drying, or increase photosynthesis. Instead, it can reduce plant vigor and yield.
