What is the main function of a groundnut digger?
C
Uprooting and separating groundnuts from the soil
Analysis & Theory
Groundnut diggers loosen soil and uproot the plants to separate pods.
Which implement is commonly used for manual harvesting of groundnuts?
Analysis & Theory
Hand forks help to loosen soil and lift groundnut plants during manual harvesting.
A tractor-operated groundnut digger is typically attached to the:
Analysis & Theory
Implements like diggers are attached to the tractor’s three-point hitch for lifting.
What part of the groundnut digger cuts and lifts the plant?
Analysis & Theory
The lifter blade goes under the soil to cut and lift the plant with pods.
Groundnut digger windrowers are used for:
C
Lifting, shaking, and windrowing plants
Analysis & Theory
They dig, shake soil from roots, and arrange plants in rows (windrows) for drying.
Which is a traditional method of turmeric harvesting?
Analysis & Theory
Farmers often use mattocks or crowbars to dig out turmeric rhizomes.
The main objective of turmeric harvesting implements is to:
C
Loosen and lift rhizomes without damage
D
Separate husk from grain
Analysis & Theory
Implements must loosen soil and lift turmeric rhizomes gently to prevent damage.
What component in a tractor-operated turmeric harvester separates rhizomes?
B
Digging blade and conveyor
Analysis & Theory
The blade digs soil and the conveyor helps elevate and separate the rhizomes.
Which implement reduces drudgery in turmeric harvesting?
B
Power tiller mounted turmeric digger
Analysis & Theory
Power tiller operated diggers reduce manual labor and harvesting time.
In groundnut harvesting, what is windrowing?
C
Arranging uprooted plants in rows
Analysis & Theory
Windrowing is arranging uprooted plants in rows for drying before collection.
What type of soil is ideal for mechanical turmeric harvesting?
Analysis & Theory
Loamy and sandy loam soils are loose and ideal for mechanical turmeric harvesting.
Which machine helps separate soil from turmeric rhizomes after lifting?
Analysis & Theory
Shaker units remove soil and debris during the harvesting process.
Which is **not** a benefit of mechanical groundnut harvesting?
A
Reduced labor requirement
D
Increased harvesting efficiency
Analysis & Theory
Mechanical harvesting should reduce damage; increased damage is a disadvantage.
Power tiller operated turmeric diggers are suitable for:
C
Medium and small holdings
D
No practical application
Analysis & Theory
These are best suited for small and medium farms due to compactness and affordability.
Which of the following is **not** part of a groundnut digger?
Analysis & Theory
Metering units are part of sowing devices, not harvesting implements.
What is a drawback of manual turmeric harvesting?
B
Uncontrolled seeding rate
C
Increased rhizome damage and labor fatigue
Analysis & Theory
Manual digging can damage rhizomes and cause fatigue due to hard labor.
Which of the following is a post-harvest operation in turmeric?
C
Boiling and drying rhizomes
Analysis & Theory
After harvesting, turmeric rhizomes are boiled and dried as a part of post-harvest processing.
How does a tractor-operated digger reduce groundnut pod loss?
A
By cutting plants at soil surface
B
By loosening soil uniformly and lifting entire plant
C
By spraying herbicide before harvest
D
By applying fertilizer during harvest
Analysis & Theory
Uniform loosening and lifting help retain pods on the plant, reducing loss.
Which implement is used for lifting and separating groundnut pods in one pass?
A
Groundnut digger shaker
Analysis & Theory
Groundnut digger shakers lift plants and shake off excess soil in one operation.
Which harvesting tool is most suitable for hilly turmeric fields?
A
Power tiller operated digger
Analysis & Theory
Simple tools like hand hoes are practical in uneven hilly terrains where machines cannot operate.
