🧮 QUICK CALCULATION CHECK

━━━━━━━━━━━━━━━━━━

Q1. AVAILABLE WATER

Available water = Field Capacity − Permanent Wilting Point

= 30% − 15%

= 15%

Root-zone water = 15% × 40 cm

= 6 cm

👉 Answer: C

Q2. APPLICATION EFFICIENCY

Application efficiency = Stored water ÷ Applied water × 100

= 7 ÷ 10 × 100

= 70%

👉 Answer: D

Q6. PLANT POPULATION

Area occupied by one plant:

20 cm × 10 cm = 200 cm²

One hectare = 100,000,000 cm²

Plant population:

100,000,000 ÷ 200

= 500,000 plants/ha

👉 Answer: D

Q15. FEED CONVERSION RATIO

FCR = Feed consumed ÷ Fish biomass gain

= 1,600 ÷ 800

= 2.0

👉 Answer: D

Q16. BENEFIT-COST RATIO

B:C Ratio = Total Benefits ÷ Total Costs

= ₹15 lakh ÷ ₹12 lakh

= 1.25

👉 Answer: C

🧠 PROFESSIONAL REVISION — 12 MUST-KNOW POINTS

━━━━━━━━━━━━━━━━━━

🧪 1. AVAILABLE SOIL WATER

Available water is approximately the difference between field capacity and permanent wilting point.

🎯 AVAILABLE WATER → FC − PWP

💧 2. IRRIGATION APPLICATION EFFICIENCY

It indicates the proportion of applied irrigation water effectively stored in the intended root zone.

🎯 EFFICIENCY → STORED WATER ÷ APPLIED WATER

🌱 3. SOIL ORGANIC MATTER

Organic residues contribute to aggregation, nutrient cycling, microbial activity and soil-health improvement.

🎯 ORGANIC MATTER → STRUCTURE + BIOLOGY + NUTRIENT CYCLING

🌾 4. HYBRID SEED PURITY

Isolation helps prevent unwanted pollen contamination and protects genetic purity.

🎯 SEED PURITY → ISOLATION + CONTROLLED POLLINATION

🧬 5. APOMIXIS

Apomixis enables seed formation without normal fertilisation and can help maintain maternal genotype.

🎯 APOMIXIS → SEED WITHOUT NORMAL FERTILISATION
