Of all the challenges faced by farmers, yellowish leaves in pea crops after irrigation is a frequent one. Once irrigation is done, farmers often notice a change in the color of the leaves of their pea crops. This yellowing of the leaves can be a signal of an underlying issue that needs to be addressed before it becomes detrimental to the entire crop.
One of the common causes of a yellowish leaf in pea crops after irrigation is excessive watering. While the plants require sufficient water for their growth, over-watering can lead to poor aeration of the soil and waterlogging. As a result, the roots of the pea plant cannot access the necessary nutrients, leading to yellowing of the leaves.
Another factor that contributes to the yellowish leaves in pea crops after irrigation is nutrient deficiency. Due to excessive watering, the nutrients that are present in the soil may get washed away, leaving the pea plants devoid of the vital nutrients. Iron deficiency is often responsible for the yellowing of the leaves. Lack of iron for the plants affects the absorption of other nutrients, causing stunted growth and yellowing of the leaves.
Pests and diseases can also be a cause for yellowish leaves in pea crops after irrigation. Root-knot nematodes are a common pest that feeds on the root system of the plants and always lead to yellowing of the leaves. Fungal diseases such as powdery mildew and rust can also lead to the yellowing of pea leaves after irrigation.
Farmers can take appropriate measures to prevent yellowish leaves in pea crops after irrigation by practicing proper irrigation techniques. Avoid over-watering and monitor the soil to ensure the pea plant receives the right amount of water. Additionally, applying appropriate doses of fertilizers rich in nutrients such as iron may help prevent nutrient deficiency.
It is essential to practice crop rotation to prevent pest and diseases in the crops. This involves planting different crops in a particular field to disrupt the lifecycle of pests and diseases. Additionally, applying appropriate pesticides and fungicides can keep the pests and diseases at bay.
In conclusion, yellowish leaves in pea crops after irrigation can be a sign of a serious issue. Farmers must practice proper irrigation techniques, monitor the soil, and provide appropriate nutrient requirements to keep the crops healthy. Taking the right measures is necessary to prevent pests and diseases from ruining the crops and yields.
