Sample Tamil Nadu HSE Second Year Agricultural Science Practice Questions

Try these sample questions to review concepts for the Tamil Nadu HSE Second Year Agricultural Science exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1In India, the kharif cropping season is primarily associated with which rainfall pattern?

A.Southwest monsoon rains during the warm wet season

B.Northeast monsoon rains only in winter

C.Only artificial snowmelt irrigation

D.Polar frontal rains of temperate Europe

Explanation: Kharif crops are sown with the onset of the southwest monsoon (roughly June–July) and harvested in autumn; they depend mainly on monsoon rainfall.

2Which crop is a classic rabi cereal widely grown under cooler post-monsoon conditions in India?

A.Paddy (rice) as the sole rabi cereal everywhere

B.Wheat

C.Sugarcane only as a pure kharif annual

D.Coffee as a field cereal

Explanation: Wheat is the principal rabi cereal in India, sown after monsoon rains recede and grown through the cool season.

3The C:N ratio of a good quality farmyard manure (FYM) after proper composting is generally around:

A.About 200:1 like fresh wood chips

B.About 1:1 with pure nitrate salt

C.About 20:1 to 30:1

D.Infinite because manure has no carbon

Explanation: Well-rotted FYM typically has a moderate C:N ratio near 20–30:1, suitable for soil application without severe nitrogen immobilization.

4Which primary nutrient is most associated with promoting vegetative growth and is a major constituent of chlorophyll and amino acids?

A.Calcium as the only chlorophyll metal

B.Silicon as an essential macronutrient for all crops

C.Chlorine as the bulk structural nutrient

D.Nitrogen

Explanation: Nitrogen is required for amino acids, proteins, and chlorophyll; deficiency causes general chlorosis and stunted vegetative growth.

5Phosphorus in plants is especially critical for:

A.Energy transfer (ATP), root development, and early crop establishment

B.Only leaf green colour with no role in energy transfer

C.Replacing all water in the xylem

D.Eliminating the need for any other nutrient

Explanation: Phosphorus is central to ATP/ADP energy transfer, nucleic acids, and strong early root growth; deficiency often shows as purpling and poor establishment.

6Potassium in crops is best known for contributing to:

A.Being the metal centre of chlorophyll only

B.Osmoregulation, enzyme activation, disease tolerance, and quality of produce

C.Fixing atmospheric N2 in all cereals without microbes

D.Acting solely as a soil pH acidifier

Explanation: Potassium activates many enzymes, regulates stomata and turgor, and improves stress tolerance and produce quality.

7In rice cultivation, the System of Rice Intensification (SRI) emphasizes:

A.Broadcasting maximum seed rate with continuous deep flooding always

B.Never transplanting and abandoning all water control

C.Young single seedlings, wider spacing, intermittent irrigation, and organic matter with careful weeding

D.Using only pure sand culture without soil

Explanation: SRI practices typically include young single seedlings, wider spacing, alternate wetting and drying, and organic enrichment to improve root growth and efficiency.

8Which tillage practice leaves most crop residue on the surface and minimizes soil disturbance?

A.Deep mouldboard ploughing every week

B.Complete soil inversion to bury all residue always

C.Flooding fields to remove topsoil

D.Zero or conservation tillage / no-till

Explanation: Zero/conservation tillage minimizes mechanical disturbance and retains surface residue, reducing erosion and conserving moisture.

9The field capacity of a soil refers to:

A.The amount of water retained after excess free drainage following saturation

B.The permanent wilting point water content only

C.The water content when soil is completely dry oven-baked

D.Only the water vapour in air above the crop

Explanation: Field capacity is the soil moisture retained after gravity has drained excess water from a saturated soil, typically after 1–3 days of free drainage.

10Available water capacity for plants is conceptually the water held between:

A.Saturation and oven dryness only

B.Field capacity and permanent wilting point

C.Only hygroscopic water films unavailable to roots

D.Air-dry residue and pure ice

Explanation: Plant-available water is mainly the fraction between field capacity (upper) and permanent wilting point (lower).
