Key factors for growing sugarcane
Sugarcane consists of four principal parts, the root system, the stalk, the leaves and the inflorescences.
Sugarcane is propagated vegetatively from cuttings with a limited number of buds, each of which may develop into a primary stem.
The stalk consists of nodes and internodes. The length of the internode varies from short at the bottom and at the top of the stalk to long in the middle section.
The leaf consists of two parts, the blade and the sheath, separated by a leaf joint.
Influences sugarcane yield and quality (Nitrogen increase the number of millable cane and total weight of stalk ), Optimum N concentration of 1.95 – 2.0% in plant at tillering has been estimated to be essential for maximum cane yield. Excess Nitrogen leads to delays maturity and ripening, lowering juice quality and make crop susceptible to lodging, pest and disease incidence.
Phosphorus important for cell division, stimulates root growth and tillering, It’s influence length, girth, cane Population and yield of millable cane. Phosphorus content in juice eliminate colloids during processing (300 ppm P2O5 concentration in juice has been rated as a critical limit for better crystallization and colour finished product “sugar” ).
Potassium has its better effect on tillering ratio, primary index, cane yield and sugar accumulation. It develops resistance to sugarcane against pest, disease and lodging and Maintains cell turgidity under moisture stress conditions.
It is essential for synthesis of amino acids, protein and vitamins in sugarcane, increases the juice quality, cane yield. And It provide protection against stresses such as salinity, drought, metal toxicity and extreme temperatures.
Magnesium is both an enzyme activator and a constituent of many enzymes and is the central element of the chlorophyll molecule. It’s deficiency is first evident on older leaves. Red necrotic lesions result in a “rusty” appearance.
Mn sparks the photosynthesis process by splitting water molecules fixes light to initiate the conversion of CO2 and water into carbohydrates. It act as catalyst in oxidation-reduction reactions and activator of many enzymes in sugarcane plant And helps in iron and nitrogen metabolism, chlorophyll formation.
