🧠 IBR AFO MAINS INTELLIGENCE

━━━━━━━━━━━━━━━━━━

🔹 1. CLIMATE-RESILIENT CROP IMPROVEMENT

Recent ICAR work highlights the increasing emphasis on varieties combining:

🌾 Productivity

🌡️ Heat tolerance

💧 Drought tolerance

🌊 Flood tolerance

🦠 Disease resistance

🥗 Nutritional quality

🎯 AFO CONCEPT:

A climate-resilient variety should not be interpreted simply as a high-yielding variety. The important consideration is stable performance under relevant environmental stresses.

━━━━━━━━━━━━━━━━━━

🔹 2. MATSYAMETRI — DIGITAL FISHERIES

MatsyaMetri uses smartphone-based image technology to estimate fish dimensions without physical handling.

Potential applications include:

🐟 Length-frequency analysis

📊 Fisheries stock assessment

🌊 Resource monitoring

🎯 EXAM TRAP:

MatsyaMetri → Fish measurement

━━━━━━━━━━━━━━━━━━

🔹 3. RAINFED AGRICULTURE

Rainfed farming requires management of both:

💧 Water availability

🌱 Soil moisture conservation

Important approaches include:

• Timely sowing

• Drought-tolerant varieties

• Mulching

• Residue retention

• Contour-based measures

• Crop diversification

🎯 KEY CONCEPT:

Rainwater management → Infiltration → Soil moisture → Stable yield

━━━━━━━━━━━━━━━━━━

🔹 4. NITROGEN MANAGEMENT

Major nitrogen-loss pathways include:

💨 Volatilisation

💧 Leaching

🌱 Denitrification

🌾 Crop removal

The dominant pathway depends on:

Soil type

Moisture

pH

Temperature

Fertiliser source

Drainage

🎯 EXAM TRAP:

Do not associate every nitrogen loss with a single mechanism.

━━━━━━━━━━━━━━━━━━

🔹 5. SODIC SOIL RECLAMATION

Sodic soils generally show:

⬆️ Exchangeable sodium

⬇️ Aggregate stability

⬇️ Infiltration

⬇️ Permeability

Gypsum supplies calcium that helps replace exchangeable sodium.

But gypsum alone is not the complete solution.

AMENDMENT → LEACHING → DRAINAGE

is the key management sequence.

━━━━━━━━━━━━━━━━━━

🔹 6. PLANT NUTRIENT MOBILITY

Mobile nutrients generally show deficiency symptoms first in older leaves.

Examples:

Nitrogen

Phosphorus

Potassium

Magnesium

Less-mobile nutrients tend to show symptoms in younger tissues.

🎯 EXAM TRAP:

Magnesium deficiency → commonly older leaves first.

━━━━━━━━━━━━━━━━━━

🔹 7. ETL IN IPM

Economic Threshold Level:

Pest density → control decision

The objective is to initiate control before the pest population causes economic loss.

🎯 MEMORY RULE:

ETL = Action point

EIL = Economic loss level

━━━━━━━━━━━━━━━━━━

🔹 8. SEED QUALITY

Seed quality has multiple dimensions:

🌱 Germination

🧬 Genetic purity

🧪 Physical purity

💧 Moisture content

🦠 Seed health

🎯 EXAM TRAP:

High germination does not prove genetic purity.

━━━━━━━━━━━━━━━━━━

🔹 9. HETEROSIS

Heterosis = hybrid vigour

It refers to superior performance of an F₁ hybrid over its parents for one or more traits.

Applications are particularly important in commercial hybrid breeding.

━━━━━━━━━━━━━━━━━━

🔹 10. AGRICULTURAL FINANCE

Credit appraisal should move beyond:

Gross income

towards:

Cash flow → repayment capacity → risk → debt servicing

Relevant risks include:

🌦️ Production risk

💰 Price risk

💳 Existing debt

🌾 Yield variability

📉 Market volatility
