In December, almost all the varieties of sugarcane are ready for harvesting.
Harvesting of sugarcane should be done at a time when the sugarcane juice becomes 18 percent brix and sugarcane has the highest amount of sucrose because this state is for a short time and as the temperature rises, the change of sucrose into glucose starts.
Use Refractometer to conduct a survey for maturity before harvesting. Sugarcane should be harvested from the surface of sugarcane.
Due to low temperature in December, there is low germination from the root of harvested sugarcane.
Immediately after the harvesting of sugarcane, spray 2, 4-D weedicide by dissolving in 500-600 litres of water on the remaining (lower) portion of sugarcane and lay the thick folds (15-20 cm) of dry leaves of sugarcane on top of the surface, doing this increases the germination.
In autumn sugarcane, if irrigation is not done in the second fortnight of November then weeding and hoeing should be done after irrigation.
Apply intercropping of mustard & coriander with autumn sugarcane and use 20 kg of Trichoderma per hectare.
Weeding-hoeing is beneficial in co-cropping farming by irrigating as needed.
Sugarcane residue management after harvesting
- After sugarcane harvesting, first collect the sugarcane residue and arrange it in alternate beds.
- The residue pieces or roots of sugarcane should be cut very close to the soil.
- Prepare a solution of 250 ml Carbendazim and 250 ml Chlorpyriphos in 100 litres of water & spray it on residue garbage.
- Irrigate the field so that the residual waste can absorb enough moisture.
- Take 200 litre of water & make a solution of 200 kg of cow dung. Add 10 kg of decomposer in it, so that mixture could be decomposed quickly.
- After decomposing of prepared solution, spray it on residue garbage of sugarcane.
