ASRB NET Fruit Science Exam Pattern & Qualifying Rules
The Agricultural Scientists Recruitment Board (ASRB) conducts the National Eligibility Test (NET) to certify eligibility for the position of Assistant Professor / Lecturer in State Agricultural Universities (SAUs) and other agricultural higher education institutions.
Unlike competitive fellowship exams where rank dictates selection, ASRB NET is a qualifying standard examination. Achieving the minimum benchmark percentage certifies lifetime NET validity.
Key Exam Takeaways:
- Conducting Authority: Agricultural Scientists Recruitment Board (ASRB New Delhi)
- Total Questions: 150 Objective MCQs (Total: 150 Marks)
- Examination Duration: 120 Minutes (LAN-Based CBT Online)
- Negative Marking Penalty: -0.33 Marks for each incorrect attempt

- Validity: Lifetime eligibility for Assistant Professorship
High-Yield Chapter Weightage in Pomology
Fruit Science requires deep taxonomic, physiological, and commercial production knowledge across four primary climate zones:
| Subject Domain | Weightage % | Recurring High-Yield Topics |
|---|---|---|
| Tropical Fruit Crops | 30% - 35% | Mango (malformation, spongy tissue, biennial bearing), Banana (panama wilt, bunchy top, suckering), Papaya (sex forms, papain extraction), Guava (wilt, training) |
| Subtropical Fruit Crops | 25% - 30% | Citrus (granulation, dieback, rootstock compatibility), Grapes (pruning, berry drop, GA3 application), Litchi (fruit cracking, air layering), Pomegranate (bacterial blight, bagging) |
| Temperate Fruit Crops | 20% - 25% | Apple (chilling requirement, dwarfing rootstocks like M9, scab), Pear, Peach, Plum, Walnut & Almond pollination mechanics |
| Post-Harvest & Biotechnology | 15% - 20% | Maturity indices, climacteric vs non-climacteric respiration, ethylene biosynthesis, controlled atmosphere storage, cold chain protocols |
