1. Maize farmers needed rainmaking services
from March to August. Cassava production in
Klonghad district (with the rainmaking service)
needed rainmaking services from March to August,
while Ta Phraya district (without the rainmaking
service) needed rainmaking services from March to
June. To reduce rainmaking service expenditure, the
Bureau of Royal Rainmaking and Agricultural
Aviation could provide services when farmers need
them. However, whether there is rainfall depends on
clouds and other atmospheric conditions. Local
officers and the radio were the major sources of
information for farmers and therefore, the Bureau of
Royal Rainmaking and Agricultural Aviation should
convey their information through these means
