2) The decisions related to Jasmine rice storage and participation in the barn-
pledging scheme of farmers.
There are three main objectives of rice storage: household consumption and seeds
(52.57%), selling (23.26%), and participation in the barn-pledging scheme (24.17%). Most farmers
who keep rice for sale and that participate in the barn-pledging scheme have more than 30 rais
of Jasmine rice paddy area. Moreover, it is also found that most irrigation area farmers sell their
rice immediately after harvest due to the necessity of investing in dry-season rice growing. Some
of the farmers have to prepare their dry season rice field and have insufficient labor to dry rice.
Meanwhile, rainfed areas have a higher proportion of farmers who stored their rice for a higher
price than irrigation areas. The southern part of the northeastern region has the most farmers
who stored their rice for a higher price and participated in the barn-pledging scheme.

The study result of factors that affect the farmers’ decision to store Jasmine rice
storage found that the independent variable in the model explains 44.91% of farmers’ decision
to store Jasmine rice. These factors which had a statistically significant influence include:
households which have a majority of female labor, the region (upper-northeastern, central-
northeastern, and lower-northeastern region), rice production pattern, Jasmine rice yields, barn
availability, and farmers who had participated in barn-pledging schemes. The households whose
labor force is made up mostly of women would more likely decide to keep rice stored for a
higher price due to the management process after harvesting requiring detailed and constant
operation. The income of households with a negative coefficient reflects that household income
is higher than the probability of selling rice immediately after harvesting. The income proportion
from the non-agricultural sector is approximately 80% of current farmer household income;
therefore, higher income households need to spend more time on non-agricultural sector
activities. In the high-income farmer group, farmers choose to sell rice immediately irrespective to
the price. Moreover, the probability of rice storage for sale by rainfed area farmers was the
highest, while it was the lowest for farmers in an irrigation area. Moreover, farmers who grow
organic Jasmine rice in rainfed areas have the option of storing Jasmine rice to sell at a lower
price than conventional Jasmine rice growing farmers. For the region variable, Jasmine rice yields
and barn availability are positively correlated with the decision of farmers to store Jasmine rice,
while the cost of rice drying, cash cost of rice production, the price of Jasmine rice during harvest
period, Jasmine rice cultivated area, rice storage volume, harvesting method, and labor used for
rice drying have no statistically significantly relationship with the decision to store rice.

It was found that farmers in rainfed areas demonstrated the highest participation in
the barn pledging project, while farmers in irrigation areas have the lowest project participation
rate. Most participating farmers are large-scale farmers with more than 30 rais of Jasmine rice
paddy production. The estimation result derived from the Binomial logistic regression model
found that the rice-drying cost, barn availability, southern part of northeastern region, number of
household labor members, plantation area, and production type have a statistically significant
influence on the decision of farmers to participate in the project. The more household labor
members one has, the possibility of participating in the project increases. Moreover, farmers who
have their own barn have a higher probability of participating in the project because to
participate they must have a durable barn that is able to store rice during the project. For the
factor of the region, it is found that the lower-northeastern region has a greater probability of
participating in the project than other areas, and farmers who have a large Jasmine rice paddy
area (more than 30 rais of Jasmine rice cultivated area) or a medium area (10-30 rais of Jasmine
