Best Fertilizers For Sugarcane In Kenya

In this article, we will explore the best fertilizers for sugarcane in Kenya. Sugarcane, a vital cash crop in Kenya, stands tall as a cornerstone of the nation’s economy. The significance of this crop underscores the pressing need for maximizing its yield. To achieve this, farmers must meticulously address crucial factors among them, nutrient balance. By doing so, they can unlock the true potential of their sugarcane crops, propelling their agricultural practices toward assured success.

Sugarcane Nutritional Needs

Sugarcane requires several essential nutrients for overall healthy growth and optimal yield. These nutrients are classified into three categories: macronutrients, secondary nutrients, and micronutrients.


Macronutrients are required by plants in large quantities. The primary macronutrients essential for sugarcane are:

  • Nitrogen (N): Nitrogen is vital for vegetative growth, chlorophyll production, and overall plant vigor. It plays a crucial role in promoting tillering, stalk development, and increasing cane yield.
  • Phosphorus (P): Phosphorus is essential for root development, energy transfer, and flower and seed formation. It contributes to early crop establishment and aids in the efficient use of other nutrients.
  • Potassium (K): Potassium is necessary for water regulation, photosynthesis, disease resistance, and sugar accumulation. It enhances stalk strength, improves drought tolerance, and increases sugar content in sugarcane.

Secondary Nutrients

Secondary nutrients are required in moderate quantities and are equally crucial for sugarcane growth. The secondary nutrients essential for sugarcane are:

  • Calcium (Ca): Calcium is crucial for cell wall formation, root development, and disease resistance. It enhances stalk strength, reduces lodging, and improves sugarcane quality.
  • Magnesium (Mg): Magnesium is a component of chlorophyll and plays a key role in photosynthesis. It is necessary for energy transfer, enzyme activation, and sugar synthesis in sugarcane.
  • Sulfur (S): Sulfur is essential for protein synthesis, enzyme activation, and chlorophyll formation. It contributes to improved sugar quality, disease resistance, and root growth in sugarcane.


Micronutrients are required in small quantities but are vital for proper plant growth and development. The essential micronutrients of sugarcane include:

  • Iron (Fe): Iron is necessary for chlorophyll synthesis, enzyme activation, and energy transfer. It plays a critical role in photosynthesis and overall plant health.
  • Manganese (Mn): Manganese is essential for enzyme systems involved in photosynthesis, respiration, and nitrogen metabolism. It promotes optimal growth, root development, and disease resistance in sugarcane.
  • Zinc (Zn): Zinc is required for enzyme activation, hormone synthesis, and carbohydrate metabolism. It aids in root development, tillering, and overall crop productivity.
  • Copper (Cu): Copper is involved in several enzymatic processes, including photosynthesis and lignin formation. It enhances sugar transport, disease resistance, and overall plant vigor.
  • Boron (B): Boron is important for cell division, sugar transport, and pollen formation. It contributes to improved flowering, fruit set, and overall sugarcane yield.
  • Molybdenum (Mo): Molybdenum is necessary for nitrogen fixation and enzyme activity. It facilitates nitrogen metabolism and contributes to overall plant health.

Best Fertilizers for Sugarcane in Kenya

1. Nitrogen-Based Fertilizers

Nitrogen is an essential nutrient for sugarcane, as it promotes vigorous growth and enhances stalk development. Some of the best nitrogen-based fertilizers for sugarcane in Kenya include:

  • Urea: Urea is a popular nitrogen-based fertilizer that is widely used in sugarcane cultivation. It contains a high concentration of nitrogen, providing a readily available source for plant uptake. Urea is affordable, easy to apply, and promotes rapid growth when used in the correct dosage.
  • Ammonium Sulphate: Ammonium sulfate is another nitrogen-rich fertilizer suitable for sugarcane. It not only supplies nitrogen but also contributes sulfur, which is beneficial for chlorophyll formation and overall plant health. This fertilizer is best applied in split doses during the growing season.

2. Phosphorus-Based Fertilizers

Phosphorus promotes root development, flowering, and sugar accumulation in sugarcane. The following phosphorus-based fertilizers are recommended for optimum sugarcane growth:

  • Single Superphosphate (SSP): SSP is a commonly used phosphorus fertilizer in Kenya. It provides a concentrated dose of phosphorus, ensuring healthy root growth and improved nutrient uptake. It should be applied during the planting phase or at the onset of the growing season.
  • Triple Superphosphate (TSP): TSP is another effective phosphorus-based fertilizer that can enhance sugarcane yield. It contains a higher concentration of phosphorus than SSP, making it suitable for soils with low phosphorus content. Apply TSP before planting or as a side-dressing during the early growth stages.

3. Potassium-Based Fertilizers

Potassium is vital for enhancing sugarcane’s disease resistance, water regulation, and sugar content. Some recommended potassium-based fertilizers include:

  • Muriate of Potash (MOP): MOP is a popular potassium fertilizer that supplies a concentrated dose of potassium to sugarcane plants. It is affordable, easy to apply, and highly effective in improving overall plant vigor. Apply MOP in split doses during the growing season, avoiding direct contact with the sugarcane foliage.
  • Sulphate of Potash (SOP): SOP is another potassium-based fertilizer suitable for sugarcane cultivation. It contains potassium and sulfur, ensuring optimal plant growth and sugar production. SOP is particularly beneficial for soils with high magnesium levels.

4. Organic Fertilizers

In addition to chemical fertilizers, organic fertilizers can also play a significant role in sugarcane cultivation. They enhance soil fertility, improve microbial activity, and provide a slow-release source of nutrients. Common organic fertilizers suitable for sugarcane include:

  • Farmyard Manure (FYM): FYM is a valuable organic fertilizer that enriches the soil with organic matter, improves soil structure, and enhances nutrient-holding capacity. Apply well-rotted FYM during land preparation or incorporate it into the soil before planting.
  • Compost Manure: Compost is an excellent source of organic matter and nutrients for sugarcane. It boosts soil health, promotes beneficial soil organisms, and gradually releases nutrients to plants. Apply compost as a top dressing or incorporate it into the soil before planting.

Final Word

Choosing the right fertilizers is crucial for maximizing sugarcane yield in Kenya. A balanced combination of nitrogen, phosphorus, and potassium-based fertilizers, supplemented with organic fertilizers, can optimize crop production, contribute to the economy, and ensure sustainable agricultural practices for future generations.
