Question

What is the system of sugarcane planting?
A. Flat system
B. Trench system
C. Pit system
D. Layering system
Choose the correct answer from the options given below:

• A. A and B only
• B. B and C only
• C. C and D only
• D. A, B and C only

Hint:

Sugarcane planting methods are chosen based on regional climate and soil type. North India uses the "Flat" method for ease, while South India prefers the "Trench" method to prevent tall crops from falling in high winds.

Answer 1

The Correct Option is D

Step 1: Understanding the Question:
The question asks to identify the various methods or systems used for planting sugarcane setts in the field. Sugarcane cultivation requires specific land preparation to ensure proper germination, moisture retention, and structural support for the tall stalks.

Step 2: Detailed Explanation:

• Flat System (A): This is the most common method in North India. Shallow furrows (8-10 cm deep) are opened with a country plough or cultivator at a distance of 75-90 cm. Sugarcane setts are placed end-to-end in these furrows and covered with soil. It is suitable for areas with adequate irrigation and relatively level land.

• Trench System (B): Also known as the 'Java Method', this is predominantly practiced in South India and coastal areas. Deep trenches (20-25 cm deep) are dug. This method helps in preventing the lodging of the crop (falling over) because the soil is gradually hilled up around the base of the plant. It also facilitates efficient irrigation and drainage.

• Pit System (C): This is a relatively newer, intensive method where circular pits (about 60-75 cm diameter and 30-45 cm depth) are dug in rows. Setts are planted in these pits. This method allows for very high yields as it enables better nutrient management and higher plant population per unit area. It is also called the 'Ring-Pit Method'.

• Layering System (D): Layering is a method of vegetative propagation used for many horticultural plants (like jasmine or guava) where a stem is induced to root while still attached to the parent plant. It is not a standard field planting system for sugarcane, which is typically grown from 'setts' (cuttings of the stalk).

Step 4: Final Answer:
The recognized systems for sugarcane planting among the choices are the Flat system, Trench system, and Pit system. Thus, A, B, and C are the correct components.
