Yes, sure. Here is an article on the topic “Leaves are turning yellow in Onion Crop”.
The yellowing of leaves in onion crops can be a cause of concern to farmers as it indicates that something isn’t right with the onion plants. When the leaves of an onion plant turn yellow, it can be a sign of several issues that need to be identified and addressed.
One of the common causes of yellowing leaves in an onion crop is overwatering. Onions require a moderate amount of water to grow, and overwatering can drown the plants and cause the roots to rot. When the roots rot, the plant is unable to absorb essential nutrients from the soil, leading to yellowing leaves.
Another cause of yellowing leaves in an onion crop is lack of nutrients. Onions require a balanced amount of nutrients to grow healthy and produce a good yield. Nutrient deficiencies can cause the leaves to turn yellow, starting from the tips. The lack of nitrogen, a crucial nutrient for plant growth, can cause the leaves to turn yellow as well.
Pests and diseases can also cause the leaves of an onion plant to turn yellow. Onion maggots, thrips, and foliar diseases such as downy mildew and purple blotch can all cause the leaves to turn yellow and affect the overall health of the plant.
To prevent yellowing of leaves in an onion crop, farmers should ensure proper watering practices, not overwatering the plants beyond what is necessary. They should also use balanced fertilizers to provide essential nutrients to the plants. Farmers should also keep the farm clean to prevent the spread of diseases and pests.
In conclusion, yellowing leaves in an onion crop may indicate several issues affecting the plants’ health and productivity. By identifying the cause and taking the necessary steps to address them, farmers can prevent the spread of the issue and ensure a good yield at the end of the season.
