The Seed Testing Laboratory in Chittorgarh tests up to 5,000 samples annually, with 2,770 samples tested in 2021-22, revealing 253 substandard samples. The laboratory performs various tests to assess seed quality, including germination, physical purity, and seed health tests for determining infestations and diseases. Seed certification validity varies from 6 to 9 months based on the source of the seed.

5. WHAT IS SEED TESTING…?
IT IS THE SCIENCE OF
EVALUATION
THE PLANTING VALUE OF THE
SEED THROUGH SEED TESTING
WE CAN ASSESS THE QUALITY
ATTRIBUTES OF SEED LOTS

OF PLANTING LOW QUALITY
SEEDS

6. IMPORTANT COMPONENT OF SEED TESTING
SEED SAMPLING
PHYSICAL PURITY ANALYSIS
GERMINATION TEST
SEED MOISTURE TEST
SEED VIABILITY & VIGOUR TEST
SEED HEALTH

7. PHYSICAL PURITY ANALYSIS
• IN A LAB , IT REFERS TO THE DETERMINATION OF DIFFERENT COMPONENTS OF THE
PHYSICAL PURITY VIZ. PURE SEED ,OTHER CROP SEEDS, OTHER DISTINGUISHED
VARIETIES, WEED SEEDS, OBNOXIOUS WEED SEEDS AND THE INERT MATTER
• THEIRE ESTIMATION IS BY WEIGHT
• THEIRE EXPRESSION IS BY PERCENTAGE

9. SEED GERMINATION
- IS THE BASIC SEED QUALITY TEST IN EVALUATING THE
PLANTING VALUE OF GIVEN SEED LOT
- IS THE ABILITY OF SEED TO PRODUCE NORMAL SEEDLINGS
Under field conditions: Under laboratory conditions
-Is normally unsatisfactory -Is accurate
-Result are irresponsible
-Unreliable
-uniform
-reproducible
-as testing environment is controlled

-NORMAL SEEDLINGS- SEEDLINGS HAVING UNIFORM
ROOT AND SHOOT RATIO
-ABNORMAL SEEDLINGS
-HARD SEED: IN LEGUMINOUS CROPS
-FRESH GERMINATION SEED : ONLY IN PADDY
