Attempts to improve Post Harvest Management of Rice in Delta
WHH & GRET LIFT Workshop - Yangon - 29 November 2012
Slide 2
Overall approach To improve post harvest management in Delta,
WHH and GRET intervention at different levels: Spreading
comprehensive technical knowledge in reducing post harvest loss
through Farmers Field Schools process Providing access to
facilities regarding better management in harvesting and storage of
paddy at village level Improving linkages with technical institutes
and service providers
Slide 3
On Quality Seed Production GRET and WHH projects intend at
supporting good quality paddy seed production and storage.
Dedicated technical support has been provided to 255 (GRET 135, WHH
120) local seed growers including individual technical guidance
follow up and collective extension activities Besides, it was also
decided to provide different low cost and improved post harvest
management facilities (storage, seed drying kits). The objective is
to enhance production and preservation / storage of good quality
seeds, and make them available timely.

Slide 6
Dissemination strategy for seed storage The main strategy
followed in order to disseminate such new facilities can be summed
up in 3 steps: Identification of low cost technologies /
innovations, Test (at project level) and confirmation of
appropriateness and impact (at contact farmer level), Facilitation
of linkages between private sector (blacksmith for silo, Companies
for air tight bags) and farmers for accessing such facilities
Slide 7
1. Identification GRET has decided to test 2 main facilities
with different objectives and target population: 1.Household Metal
seed silo (capacity of 25 baskets) 2.Air tight bags (capacity of 2
baskets)
Slide 8
Household Metal silo Technical Facts and Manual for silo making
is provided by FAO

Slide 10
Slide 11
Selection of size of the silo height= 4 ft diameter (d)= 3.5
ft, so radius (r) = 1.75 ft Then cu ft= r h = 38.499 cu ft capacity
in gallon = 38.499 x 6.228833 = 239.81 gallons capacity in basket =
239.81 / 9 = 26.6455 baskets (need 20' x 4 ' metal sheet with 0.5
mm thickness)
Slide 12
Identification of Air Tight Bags Air tight bags have been
developed by Pioneer Post Harvest Development Group and are based
on the same IRRI design (commercialized by GrainPro company under
the name of Super Bags from the Philippines). On the 10 th of March
2010, a seminar on private sector initiatives in development of
postharvest technology in Myanmar was organized by the FSWG along
with support from GRET. Such workshop enabled GRET to assess the
seriousness and the reliability of the storage facilities presented
by Pioneer PHD Group. Taking into consideration local availability,
low cost and appropriateness criteria, PPHD have been selected over
GrainPro. Cost price for GrainPro bag= 2 USD per air tight bag +
import cost Cost price for PPHD bag = 750 MMK per air tight bag +
250 MMK per vinyl bag to cover with logos printed as we
demanded

Slide 14
2 A.Test (at project level) of appropriateness and impact It
has been decided by the project to compare the effectiveness and
the impact of improved storage facilities over the rainy season
2010. Thee Dat Yin paddy seeds harvested in 2009 RS were collected
from same farmer and sun dried uniformly to reach 13%
moisture.
Slide 15
Then, the paddy seeds were kept in different storage facilities
as follows; 3 baskets in a local type small bamboo bin covered with
mud copying conventional practice 1.5 baskets in a vinyl bag as
conventional ways 1.5 baskets in an Air Tight Bag by PPHD group
Date of storage= 08 th of July 2010 Moisture % of seed= 13.2% Date
of opening storage and germination tests= 18 th of November
2010
Slide 16
3 different storage types (8 July 2010)

18 th November 2010 0% after 3 days (< 30% after 1 week) 55%

Slide 26
Early Responses from the farmers Harvest of Thee Dat Yin were
put into silos in early November by some farmers. There are
condensation formed at the top of silo. Drying and air cooling
after drying is necessary to avoid condensation. Most of the Thee
Dat Yin seed were sold in short time for summer rice. Only seed for
own use were stored in silo. They feel safe with their seed kept in
silo. Most of the seed harvested from medium term rice were still
in the process of threshing and drying in December. It has been
observed that the air tight bags were untouched by rodents compared
to storage in PVC bags in random. It could be that the Air Tight
bags prevent the rodent to smell the paddy grains. Feedback after 2
seasons by user farmers and seed growers
Slide 27
3.Facilitation of linkages between private sector (blacksmith
for silo, Companies for air tight bags) and farmers In case
feedbacks from farmers show a very positive answer, the way forward
would be to facilitate linkages between private sector and
interested farmers. The project did not reach yet this stage but is
already working toward this direction. We have local blacksmiths
who have gained experience in making household metal silo. Some
farmers started to inquire the cost of silo and place to order for
their own use. PPHD is in line of producing Air Tight Bags to
respond orders.
