#Sugarcane_Nutrition_Understanding
#Nitrogen;
Nitrogen requirement of sugarcane is relatively higher. Nitrogen is important in tillering, internode elongation, hight of stalk, biomass production and yield. Its demand is very high during tillering stage and fast growth phase. (from 30 to 100 days). Nitrogen is most limiting nutrient in term of total yield of cane. Deficiency of nitrogen causes less tillering, stunted growth, pale yellow colour of lower leaves, early falling of lower leaves and low yeild. On average nitrogen requirement for sugarcane ranges from 80 to 120 kg/acre. Ratoon crop needs more nitrogen as compared to 1st year crop. #Phosphorus;
Phosphorus is needed in less quantities, especially in early growth. It is very important for roots development and tillering. On later stages it helps in maturity of crop and increases sugar content. Its deficiency causes poor roots development, less tillering and less dens canopy. Average requirement of phosphorus ranges from 20 to 30kg/acre. #Potassium;
Sugarcane needs potassium in very high amount. Potassium helps to utilize nitrogen properly and develops resistance against diseases. It increases weight and sugar content of cane. It helps crop to stand against strong winds. Its deficiency leads to browning of lower leaves and thin stalk. Overall its deficiency causes much loss in yield. Its average requirement is 150 to 250 kg/acre. Iron;
Iron is micronutrient, but sugarcane need it in good quantities. Iron deficiency in sugarcane is common in Pakistan. It causes chlorsis on younger leaves. It is important for good health of crop. So foliar or soil application of ferrous sulphate is better practice.
#Sulfur; Sulfur requirement is low for sugarcane, but Pakistani soils are sulfur deficient, so some sulphate is good to add. Its deficiency appears on top leaves which turn yellow.
#Fertilizer_Plan
During soil preparation, add 1 DAP or 1.5 NP (place DAP or NP in bands, below sets) along with 1 MOP and 20 kg bentonite sulfur.
For September sowing, use half dap + half mop along with sulfur at sowing and remaing dap and mop in march during earthing up.
After 30 days give 1 bag CAN or 30kg urea
After 60 days give 1 bag CAN or Urea along with 25 kg MOP.
After 90 days give 1 bag CAN or Urea along with 25 kg MOP.
After 110 days 1/2 bag urea.
#Note: Don't waste money on phosphatic fertilizers, as extra use of phosphorus will not pay back. Don't give nitrogen after 120 days, otherwise it will delay maturity and will cause new tillering and will loss cane yield. Give 2 micronutrients spray at 30 day and 60 days.
