Sugarcane is a major cash crop for farmers in Uttar Pradesh, Maharashtra, Karnataka, Tamil Nadu, Andhra Pradesh, Gujarat, Bihar, Haryana, and Punjab. All of these farmers depend on the quality and quantity of their sugarcane harvest for their livelihoods.
The silicon nutrient was found to be extremely important for increasing the yield of this crop in a recent study. Sugarcane absorbs silicon as silicic acid, which is stored in the leaves. Sugarcane plants can absorb as much as 700 kg of silicon per hectare.
Benefits of Silicon for Sugarcane
1) Growth of Crops:
Activated silica gel is found in the cell walls of the leaves as a form of storing silicon. The leaf blade forms a thick layer as a result. The process of photosynthesis is enhanced, which increases stem height and thickness. In addition, it increases the crop’s ability to withstand water stress.
2) Maintains a Constant nitrogen percentage:
Manganese, for example, does not stay in one place if the percentage of soluble silicon in the leaves exceeds 0.7%. Therefore, their adverse effects are prevented. Silicon inhibits the fixation of phosphorus in the soil and phosphorus is readily absorbed by the crops. Furthermore, the amount of Phosphorus in the crops is controlled. Efforts are made to reduce the adverse effects associated with excessive nitrogen, and silicon helps to maintain nitrogen levels.
Silicon Fertilizer Recommendation:
Farmers cannot afford silicon fertilizers made from chemical sources, so they cannot use them. As per the guidelines of Mahatma Phule Agricultural University, when 1 to 1.5 tonnes of trash bags are used in sugarcane, 400 kg silicon is provided for the crop. Sugarcane is also supplied with silicon through the compost of trash.
Silicon & Soil Fertility:
Growth of crops, supply of nutrients, and proper balance of air and water are all provided by soil. Soil health is improved by the use of silicon fertilizers. Humus is added to the soil and encourages root growth. Increases sugarcane’s water holding capacity Supports proper air and water balance Facilitates bacterial function It has also been demonstrated that soil and organic carbon levels are increasing. Furthermore, it is useful for reducing evaporation from the soil at higher temperatures.
