Iron deficiency is a common problem in paddy cultivation. This problem can be easily identified by the yellowing of the leaves, resulting in stunted growth and lower yields. The main cause of iron deficiency is the alkaline nature of the soil, which makes it difficult for the paddy plant to absorb iron.
There are several ways to control iron deficiency in paddy, some of which are as follows:
1. Soil Correction: The first step in controlling iron deficiency is to correct the soil pH. This can be done by applying sulfur or organic matter to the soil. The ideal pH for paddy cultivation is between 5.0 and 6.5.
2. Fertilization: Adding iron to the soil is another way to control iron deficiency. When fertilizing paddy plants, it is essential to use a fertilizer that contains both nitrogen and iron. Iron chelates or Fe-EDDHA are commonly used by farmers to ensure that their crops receive enough iron.
3. Soil Aeration: Soil compaction can also contribute to iron deficiency. Therefore, farmers need to ensure that the soil is appropriately aerated to allow air to reach the roots. This can be achieved by tilling the soil or using aeration tools.
4. Water Management: Iron deficiency can also be caused by poor water management. To control iron deficiency, farmers must ensure that their paddy fields receive the right amount of water. Waterlogging and inadequate irrigation can also cause iron deficiency.
5. Iron Foliar Spray: Iron foliar spray can also be used to control iron deficiency. This is a quick and effective way to provide nutrients to the plant. Iron foliar spray is applied directly to the leaves of the paddy plant, and it helps to improve the uptake of iron.
In conclusion, iron deficiency is a prevalent problem in paddy cultivation. However, it can be controlled by applying the right soil correction measures, fertilization, soil aeration, water management, and iron foliar spray. By following these steps, farmers can ensure that their crops receive enough iron and produce higher yields.
