6. TOPIC : Field Inspection

7. Field Inspection:
Field inspection, that is, inspection of
standing seed crops is an essential step in
verifying conformity of seed crops to
prescribed certification standards.

8. Objectives of field inspection:
1 . To verify seed origin (source seed) and identity of the variety.
2 . To collect information on cropping history of the seed field, that is, to
verify whether the seed field meets the prescribed land requirements.
3 . To check crop and cultivation conditions.
4 . To check isolation distance.
5 . To check freedom from impurities, namely, other crop plants and weed
plants

9. 6 . To check freedom from other cultivars and off-types.
7 . To check freedom from seed-born diseases.

10. General Principles Of Field Inspection
◦ All field inspections must be made by well-trained and qualified
personnel.
◦ The prescribed procedure and techniques of field inspection and the
minimum number of inspections specified in the certification
standards
◦ Inspection of cross-pollinated crops during flowering, and those self-
pollinated crops which are inspected by designated seed-born
diseases during flowering stage.
◦ The seed inspector should achieve full co-operation from seed
growers, even the case of the rejection of a field.

11.  Upon arrival at the seed farm, the inspector should check all
information about species, variety, seed origin, cultivated area, class of
seed, cropping history of the field.
 Each field and its boundaries must be pointed by the seed grower.

12. Fig :- Walking patterns for field inspection
1- observation of 75% of the field
2- observation of 60 to 70% of the
field
3- at random
4- clockwise travel pattern
5- observation of 85% of the field
6- observation of 60% of the field

13.  During the walk in the field, the inspector must make estimates of
other varieties and impurities, diseased plants, general condition of
the crop, applied farm practices and possible yield.
 If the direction of plant rows permits, the inspector should walk
through his side or back.

14. METHOD OF ISPECTION:-
The inspection of a seed crop is done at different stages of a crop
growth so as to make various verifications and estimates of various
impurities, off-types and diseases, etc. Mentioned below are the
objectives to be accomplished at a given stage of crop inspection.
Crop Stages of Inspection:-
1. Inspection at the time of sowing:-
Sowing time inspections to educate the farmers participating in a
certified seed production programme for the first time, or at times when a
new crop is introduced, are very helpful in maintaining good quality of
seed. The purpose is to explain to the land and isolation requirements,
to check whether their seed field meet such requirement; to verify their
foundation seed bags ; planning; planning ratio, making of male ,rows

15. Sowing time seed treatment, etc In biennial crop the main objective is to
verify purity of roots/stem at the time of transplanting.
2.Inspection During pre flowering/vegetative stage;-
The purpose of pre-flowering inspection is to educate growers regarding
plants to be rogued and to suggest other corrective majors if require,
after the following verification.
1.That the seed planted to produce the seed crop was eligible for use
and was obtained from as approved source
2. That the planting ratios (in hybrid production), isolation requirements
and land requirements have been mate.
3. That the seed crop has not been grown as mixed cropping, inter
cropping or companion cropping or ratoon cropping

16. 3.Inspection during flowering stage:-
Flowering time inspections. Especially in cross-pollinated crops and
those self-pollinated crops which are infected by systemic seed-borne
disease at flowering stage.
1. Check whether various corrective measures, suggested earlier
have been carried out.
2.check or recheck the land and isolation requirements, planting
ratios and source seed.
3.take detailed counts for various concentrating factors as per
procedure described later in this chapter.
4.advice the farmer to continue rouging during flowering secession.

17. 4. Inspection during post flowering and pre-
harvest stage.
During this inspections detailed counts should be taken to the
determined the extent of various contaminants present in the seed field
and to educate the farmer regarding the rouges which where not
identifiable earlier so as remove them before final inspection.

18. Contaminates to be observed during field
inspection:-
1.Off types.
2.Pollen shedder.
3.Shedding tassel.
4.Inseperable other crop plants.
5.Obejtional weed plants.
6.Diseased plants.

19. Method of Taking Field Count:-
1. Determine the number of field counts.
2. Number of plants to be observed for completing.
3. Taking the field count.
(method of taking field count in
thickly-sown row crop)
For wheat, barley, oats, soybean,
jute, mesta etc.

20. Method taking count in broadcast crop
