Management of Sugarcane Ratoon
The total economy of sugarcane crop is directly dependent upon the successful raising of ratoon crop. With proper management ratoon crop can give as high yield as the plant crop. The first ratoon is only recommended as the subsequent ratoon runs the risk of weeds, pests and diseases and results into poor yields. For a satisfactory ratoon, the canes of plant crop be harvested at ground level or slightly below and stubble shaving is done to allow buds situated on the underground portion of stubble to sprout. The top soil in a ratoon field has to be worked well by ploughing along cane rows. Immediately after the stubble shaving, it is desirable to cover the field with trash. The sprouting from early harvested plant crop in November and December is poor due to the frosty conditions during December and January. To obtain a good ratoon crop, February and March harvesting are found better. When irrigation facilities are available, crop should be irrigated as per the schedule for plant crop. Co J-64 and CO 1148 are good varieties for ratooning but the later yields more than the former. Ratoon crop matures earlier than plant crop. Besides cost of cultivation is low in ratoon than plant crop. To harvest the best ratoon, the following practices should be adopted :
- Harvest closely to ground for better sprouts.
- Remove late tillers or water shoots as they inhibit the full sprouting of the stubbles.
- The nitrogen requirement is one and a half times more than the main plant crop and may be applied in three splits. Drill phosphorus and potash along the cane rows towards the end of March on soil test basis.
- Fill gaps by transplanting pre-germinated shoots. The cane seed cuttings can also be used for gap filling.
- Under rainfed conditions, an application of sugarcane trash at the rate of 7.5 q/ha has been found beneficial for ratoon crop.
- Select CO 1148 as best ratooning sugarcane variety. This yields about 25 per cent more than CO J 64 in ratoon.
- An application of 2.250 kg a.i. per hectare of Atrazine controls all kinds of weeds, which should be applied a week after the harvest of plant crop as pre-emergence.
- Take timely plant protection measures as recommended for the main plant crop.
All other package of practices are the same as those for plant crop. |
