Which of the following is a multipurpose plough?

✅Explanation: MB plough (Mulch tiller plough) is a multipurpose plough because it is designed to handle various tasks such as tilling, turning the soil, and managing mulch. It is effective for both primary tillage (turning the soil) and secondary tillage (creating a seedbed) and can be used for a range of soil types and conditions.

• Main Components:

• Plough Bottom:

• This is the crucial part that directly interacts with the soil. It consists of:
-Share: The sharp, pointed part that cuts and penetrates the soil horizontally.
-Mouldboard: The curved surface that lifts, turns, and inverts the furrow slice.
-Landside: The flat plate that provides stability and helps maintain the plough's depth and direction.
-Frog: The main structural part to which the share, mouldboard, and landside are attached.

• Beam:
-The long, sturdy metal bar that connects the plough bottom to the frame or hitch.

• Frame:
-The main supporting structure of the plough, usually made of steel. It holds the beam and other components together.

• Hitch:
-The part that attaches the plough to the tractor or animal power source.

📌Other Options Explanations:
-a) Disc plough: A disc plough is used for plowing hard or dry soil. It is more specialized for cutting through tough, compacted soil.
-c) Traditional wooden plough: A traditional wooden plough is a simple, manual tool often used for tilling.
-d) Ridge plough: A ridge plough is used to form ridges in the soil, mainly for crops that benefit from ridged rows,

🔑Key Points:
Tillage: It is the mechanical manipulation of soil with tools and implements for obtaining conditions ideal for seed germination, seedling establishment, and growth of the crop.

• Objectives of tillage:
-To create conditions in the soil suited for better growth of crops.
-To control weeds effectively.
-To make the soil capable of absorbing more rainwater.
-To mix up manure and fertilizers effectively in the soil.
-Providing adequate seed-soil contact permit water flow to seed and seedling roots.

• Primary tillage:
-The operations are performed to open up any cultivable land to prepare a seedbed for growing crops known as primary tillage.
-Animal-drawn implements in primary tillage mostly include MB-plough.
-Tractor-drawn implements include MB-plough, disc plough, subsoil plough, chisel plough, and other similar implements.
Secondary tillage
-Lighter or finer operations performed on the soil after primary tillage is known as secondary tillage.
-Harrowing is to be done to a shallow depth to crush the clods and to uproot the remaining weeds and stubbles.
-Seedbed preparation and intercultural operations are done up to a depth of 15 cm.
-Secondary tillage implements: Disc harrow, spike tooth harrow, spring tooth harrow, acme harrow, etc.
