This document discusses seed health status of farmer saved seeds in India. It makes three key points:
1) Farmers in India rely heavily on saved seeds from previous harvests, with only 10-12% of crop area using certified seeds. Saved seeds often have poor quality in terms of germination, purity and health.
2) Research has shown that sorting and treating saved seeds can help reduce fungal infections and increase yields. Untreated saved seeds are more likely to be contaminated with pathogens, weeds and have lower germination rates.
3) The continuous use of poor quality saved seeds can negatively impact crop yields and quality over time. Promoting higher seed replacement rates through training, subsidized quality seeds

Seed Health Status of
Farmer Saved Seeds

3. Introduction
Seed is considered as a basic vital input for
agriculture development due to the fact that it ensures
grain production and adds new genetic resource to the
crop gene pool.
The productivity of crop is directly linked to the
quality of seed used, though management practices and
supplementary inputs exert profound influences. (Shetty.,
2000).
Though minimum standards for seed health
certification have been prescribed in India, farmers are
not yet aware of these standards. Use of seeds with poor
health status results lower plant density and yield per unit
3
5. Globally, around three quarters of the world
farmers save seeds for sowing from harvest to harvest
(Tunwar, 1988).
In India, out of 329 million hectare area, 120
million hectare area is under food crops , hardly 10-12
per cent area is grown with quality/certified seeds
(Meena Kumari et al., 2009),
Non availability of adequate quality seed forces
the farmers to use their own saved seed.
Farmers often use seed that have impurities and
contaminants which are infected with pathogens many
a times (Fujisaka et al., 1993).

6. Farmers rely on and use farm saved seeds to the extent
of 80 to 85%. Farm saved seeds is of poor quality interms of
germination, vigour, purity (physical & genetic), health etc.
Their continuous use affect the crop yield and quality.
Source: National Conference on Agriculture for Kharif Campaign , 2007-08.
In Andhra Pradesh, 85 per cent of the seed is being used
by the farmers of their own saved seeds or the seed that
bartered or exchanged with other farmers. (Meena Kumari et
al., 2009).
It has also been reported that farmers saved seed had the
maximum percentage of ‘off-type’ plants compared to that
produced by certified seed samples of rice, green gram and
wheat (Murali et al ., 2000).
For achieving higher productivity, use of quality seed
leading to highest germination is essential

A Case study in karnataka (Ground nut)
In Karnataka, 73 per cent of farmers use their own saved seeds
24 per cent of farmers exchange the seeds or buy the
seeds from other farmers
03 per cent of farmers buy the seeds from either public
or private companies

What makes farmers to use saved seeds
of previous crop harvest?
It’s the lack of awareness on the use of
“Quality Seeds” and source of
availability of the “Quality Seeds”.
(Meena Kumari et al.,2009)
Timely availability of quality seeds (???)
16. 16
Which seeds can be saved?
Seeds can be saved to sow new crops in the future, but not
all seeds are suitable for saving.
Varieties suitable for seed saving include local varieties that
have been grown in one region for a very long time.
Self-pollinating crops (e.g., beans and peas)
Open-pollinated varieties of some cross-pollinating crops
(e.g., pepper, cucumber and carrot).
(AVRDC, 2005)
17. 17
How to keep seeds pure?
Isolation in distance
Bagging
Caging
18. 18
What is the best way to store seeds?
Seeds stored in air-tight containers to prevent them from
absorbing moisture
19. 19
Impact of use of farm saved seeds
Increase in disease incidence
Pest (insect and microorganisms) attack during
storage which hinders the crop growth upon planting
Transmission of weed seeds which suppress the crop
growth
Lower yields/crop productivity
Decline of physical purity after harvest by admixtures
and in turn lowers the germination and vigour
21. 21
Red gram storage with common
salt
In this practice, about 200 gm of salt was
mixed for a kg of red gram grains manually.
These treated grains should be stored in
jute gunny bags after stitching.
As salt has abrasive action on insect skin
prevents its movement inside the storage
containers.
Farmers opinion: This practice stored red
gram grains for short-term duration of 6-8
months. Farmers perceived this practice to be
moderately effective and affordable in cost.
22. 22
Ash seed treatment in sorghum
Ash, mixed with the sorghum (Sorghum
bicolor) seeds at the ratio of 1:4.
After the ash treatment, sorghum seeds
should be tied airtight in the jute gunny bags.
During storage, grains losses were reduced
by various insects, e.g. rice weevil(Sitophilus
oryzae), rodents,(Tatera indica) and mite
(Oligonychus indicus).
Farmers strongly believed that ash application controlled
these losses considerably up to an extent of 80%. Farmers
using this technology stored the sorghum grains for 6
months without any storage pest problems.
23. 23
Ragi storage with neem leaves
The strong odour of neem
(Azadirachta indica) leaves keep the
storage pests like lesser grain
borers (Rhyzopertha dominica), saw
toothed beetle (Oryzaephilus
surinamemsis) and flat grain beetle
(Cryptolestes minutus) away by
repellent mechanism.
Being very cheap and simple most of
the farmer followed this technology to
get rid of storage pest than to relay on
costlier chemical treatments.
24. 24
Storage of grains using
camphor
Farmers indigenously practiced
this simple method in grain storage.
In this practice, about 1gm of
camphor piece per 5 kg of grains was
placed as such in the jute gunny
bags.
A short-term storage of grains up to 3
months was possible with this traditional
storage method and after that the grains
were to be sun-dried and then kept
with fresh camphor pieces for
subsequent storage.
25. 25
Storage of seeds with lime
Farmers traditionally followed a
practice of storing pulse grains along
with lime powder.
In this practice, dusting about 10
gm of lime per kg of grains. After
thorough mixing , storing in jute gunny
bags were followed.
The lime had a property of emitting
irritating odour that repells insects and
preventing the grains from damage. By
this way, grains could be stored for even
one year.
26. 26
Storage of vegetable seeds with cow dung
Vegetable seeds such as ash gourd
(Benincasa hispida), bitter gourd
(Momordica charantia), bottle gourd
(Lagenaria siceraria), etc. are embedded in
cow dung and then dried under sun for 2-3
days.
After drying, the seeds are got to be
sticked on to the Varati. These Varaties then
stored in open / inside wooden boxes.
Farmers opinion: Vegetable seeds can be
stored by this method even up to one year.
Farmers believed that cow dung has
pesticidal property and immunostimulant
properties which could increase germination
and viability .
27. 27
This practice was being followed from more than 35 yrs,
farmers store
the tamarind (Tamarindus indica) by mixing salt with it.
After harvest, tamarind was removed from its pods and then
stored in
earthen pots in layers and spreading of salt in between the
tamarind
layers.
For this practice, about 10 gm of salt was used for per kg of
tamarind
By this way of storage, storage pests like beetles and Indian
meal moth
(Plodia cautella) were prevented.
Storage of tamarind with common salt
28. 28
Storage of grains with sweet
flag
This method was being practiced for
more than 40 yrs. Farmers practiced an
indigenous way of storing grains with
sweet flag (Acorus calamus.)
For treating 1 kg of grains, about 10
gm of sweet flag powder was used.
The grains could be stored
effectively for 6 months without any pest
attack. The strong odour emitted from
sweet flag acted as a repellant against all
the storage pests.
29. 29
Seed village
A village, wherein trained group of farmers are involved in production 'of
seeds of various crops and cater to the needs of themselves, fellow farmers
of the village and farmers of neighboring villages in appropriate time and
at affordable cost is called "a seed village“.
Concept:
Organizing seed production in cluster (or) compact area
Replacing existing local varieties with new high yielding varieties.
Increasing the seed production
To meet the local demand, timely supply and at reasonable cost
Self sufficiency and self reliance of the village
Increasing the seed replacement rate
30. 30
Features of seed village
Seed is available at the door steps of farms at an
appropriate time
Seed availability at affordable cost even lesser than
market price
Increased confidence among the farmers about the
quality because of known source of production
Producer and consumer are mutually benefited
Facilitates fast spread of new cultivars of different kinds
31. 31
Advantages of Seed Village Concept
1. Solve the problem of isolation. Mainly in cross pollinated crops like
maize, sunflower where it required more Isolation distance the problem
will be solved by raising a single variety in a large area.
2. Mechanization is possible from sowing to harvesting
3. Post harvest handling of seed will be easy
.
4. Because of a single variety, the problem of varietal admixture during
processing, drying will be avoided
5. Seed certification official will cover large area per unit time
6. Totally , it reduces the cost of cultivation
7. Seeds produced will be with high genetic, physical purity
32. 32
Recommendations of National Conference on Agriculture for
Kharif Campaign 2007-08
Farm saved seeds is of poor quality and their continuous use
affects their quality and consequently their yield. Therefore, need for
promoting and encouraging higher seed replacement rate is very much
essential by following ways:
(a) Training of farmers in seed production technologies, particularly hybrid
seeds.
(b) Supply of inputs like better quality seeds and parental lines to farmers
at subsidized rates and on easy terms.
(c) Support for creating infrastructure including irrigation facilities for
seed production.
(d) Support for acquisition of storage and seed processing facilities.

Firew Mekbib
(2008)
Noticed that in sorghum average germination for the three varieties tested was
82.8% in ethopian farmer saved seeds. The conventional purity (varietal) level of
98% was not met due to the dominant practice of varietal mixture in the region.
The dominant storage methods for seed were panicles form hung in the house
(74.4%) or as threshed seed stored in sacks (83.7%). Smoking of panicles (33.8%)
and chemicals (22.6%) for threshed seed were commonly used seed protection
measures.

Conclusion
Farmer saved seeds are of poor quality, therefore
farmers need to have knowledge on seed borne pathogens,
storage structure and their importance, and also farmer
should be aware of difference between seed and grain.
If farmers are educated to take proper measures to
keep the seeds in good conditions including the health
status, the yield of such seeds can certainly be enhanced
further undoubtedly.
Simultaneously farmers must be advised by
institutions to use the processed certified seed for getting
maximum yield benefits.
