Ferrous Sulphate is a vital nutrient that plays a critical role in the growth and development of plants, particularly in wheat crops. It is a soluble source of iron that can easily be absorbed by the plant roots. Iron deficiency is a common issue in wheat crops, resulting in chlorosis, reduced growth, and yield loss. Therefore, farmers need to apply Ferrous Sulphate spray at the appropriate time and dosage to ensure its effectiveness.
The best time to apply Ferrous Sulphate spray on wheat crops is during the early growth stage. This stage is crucial as the plant is actively growing and requires a sufficient supply of iron for proper development. It is recommended to apply Ferrous Sulphate spray when wheat crops are between the vegetative and reproductive growth stage, which is usually around 20-30 days after sowing.
The dosage of Ferrous Sulphate spray varies according to the level of iron deficiency in the soil and the stage of crop growth. Generally, 10-15 kg of Ferrous Sulphate is recommended per acre. This dosage can be adjusted based on the soil test results and the crop requirement.
Before applying Ferrous Sulphate spray, it is essential to ensure that the soil pH is between 5.5 to 7.0. If the soil pH is above or below this range, it may affect the availability of Ferrous Sulphate to the plant roots.
Moreover, it is advisable to spray Ferrous Sulphate during calm and dry weather conditions to prevent the spray from drifting and reduce the risk of crop damage.
In conclusion, Ferrous Sulphate spray is a vital nutrient that plays a critical role in the growth and development of wheat crops. Farmers must timely apply Ferrous Sulphate spray to ensure its effectiveness and prevent iron deficiency. The appropriate dosage and a suitable stage of crop growth are essential factors to consider while applying Ferrous Sulphate spray to wheat crops.
