Sure, I can help with an article on Fertilizer Dose for Ratoon Sugarcane.
Ratoon Sugarcane is the crop that is harvested after the first sugar cane crop. It is derived from the same root system and has the same potential to produce a high yield of sugarcane. Farmers who choose to plant ratoon sugarcane are looking to maximize their farm’s potential by reaping additional benefits at a lower cost.
Fertilizer plays a vital role in the growth and yield of sugarcane. Therefore, it is essential to provide the right type and amount of fertilizer to increase the production of ratoon sugarcane.
To determine the right amount and composition of a fertilizer, one should consider the soil’s fertility level, the growth stage of the crop, and the variety of sugarcane.
Here are some tips for fertilizing ratoon sugarcane:
1. Pre-Sowing Fertilizer Management:
Before sowing ratoon sugarcane, farmers must apply a basal dose of fertilizers. The basal dose of fertilizers should consist of nitrogen, phosphorus, and potassium.
For every acre of land, farmers can apply 80-100 kg Nitrogen, 40-80 kg Phosphorus, and 80-120 kg Potassium.
2. Fertilizer Management after Harvesting:
After harvesting the first sugarcane crop, the ratoon crop should receive a ratoon management dose.
The amount and type of fertilizer for the ratoon crop vary based on the yield of the first crop. If the first crop yield is low, then farmers need to give more fertilizer to the ratoon crop. The following can be used as a rule of thumb.
For every acre of land, farmers can apply 80-100 kg Nitrogen, 40-60 kg Phosphorus, and 80-120 kg Potassium.
However, if the yield of the first crop is high, the farmers can reduce the amount of fertilizer by 20-30%.
3. Splitting of Fertilizer:
It is recommended that farmers divide the amount of fertilizer they apply into multiple doses. The first dose should be applied before sowing the crop, and the other doses should be applied at regular intervals. This will help in ensuring that the crop receives a continuous supply of nutrients that are necessary for growth.
4. Application of Micronutrients:
In addition to the primary nutrients, ratoon crops need additional micronutrients to grow correctly. Farmers can either use fertilizers that contain micronutrients or use micronutrient supplements.
The most common micronutrients required for sugarcane are Zinc, Iron, and Boron. These micronutrients can improve the yield and quality of the ratoon crop.
In conclusion, proper management and adequate fertilization are necessary for the growth and maximum production of the ratoon sugarcane crop. The correct timing and composition of the fertilizers applied are essential to ensure the crop’s success. Farmers must consider the soil type, the crop’s growth stage, and variety to provide the right fertilizer dose at the right time. With proper fertilization, farmers can increase their yields and maximize their profits.
