Sugarcane Integrated Ratoon Manager

This disclosure proposes a integrated Ratoon manager (Tractor implement) which will complete major operations for Ratoon crop management in single pass.

The key operations which will get integrated by this disclosure,  Trash Picking  Stubble shaving  Trash shredding & Trash Mulching  fertilization  Spraying of pesticides  off baring/Soil breaking  Trash mixing with soil

Stubble Shaving Trash Shredding Trash Mulching

Off baring/shoulder breaking Trash mixing with Soil

Fertilization Spraying PesticidesTrash Picking


Background / Problem

Ratooning is a method of harvesting a crop which leaves the roots and the lower parts of the plant uncut to give the ratoon or the stubble crop.. In this manner, nearly 2-3 crops can be harvested without much risk and uncertainties.

 Ratoon occupies almost 50 per cent of the total area under sugarcane cultivation Contributes 30% to the total cane production in the country  Area under ratoons is relatively greater in the tropical states (50% - 55%) than in the sub-tropical states

(40% - 45%)  Average yield gap between plant and ratoon crop in the country is 20% - 25% (due to not following good

practices).  Ratoon sugarcane is the most economical among all types of sugarcane. The savings on operational cost along

with seed material is almost 25% to 30% compared to other types of sugarcane. Also there is no need for preparatory tillage to grow this crop.

 Ratoon sugarcane matures earlier than other types of sugarcane and thus early supply of cane is assured. As a result, harvesting is faster and next crop can be sow on time.

In India, one ratoon is common while in areas like U.P., Punjab, Haryana, practice of multiple ratoon is in vogue. Other countries also adopt multi-ratooning like Mauritius 6 to 8, Australia 2 to 3 and in Cuba 3. To 5.

Ratoon Plant - India Cultivation Land 50% of total area Sugarcane Production 30% of total cane production

Tropical Vs Sub Tropical Tropical states (50-55%) / Sub Tropical States (40%- 45%) - Are of cultivation

Yield Gap 25%-30% compare to first plant Economical No Seeding and land preparation cost Crop Duration Short Duration-Early Harvesting


Wrong Practice followed in Ratoon Management:

 No Stubble shaving  Complete burning of trashes in fields leading to sprouting failures  Not utilizing sugarcane trash which is a rich source of organic carbon and plant nutrients  No off barring/soil breaking (Soil compaction)  Improper planting material  Poor nutrient supply for the ratoon  Inappropriate plant density (gap filling) (out of scope of mechanization)  Farmers treat ratoon crop as a free gift crop without bestowing much attention for its maintenance.

Background / Problem

 Required operations for Ratoon management not followed  No integrated solution available in India market (different machines for each operation)  Inefficient and time consuming operations
