| Abstract | This study aims to determine whether or not the seed distribution
system for leafy vegetables in Pathum Thani, Thailand, is effective. Using
a structured questionnaire, information was collected from vegetable growers
who have grown leafy vegetable on at least 2 rai (0.3 ha) of land year-round
for commercial purposes. Seed samples were collected during interviews with
respondents. Seed testing was done in laboratory following the rules of The
International Seed Testing Association (ISTA). The data was analysed by using
the Statistic Package for Social Science (SPSS).
High competition among vegetable seed companies is indicated revealing
seed distribution system that can provide seed to vegetable growers at the
time they need it. However, they use brands which they realized were of good
varietal quality. Most leafy vegetable seeds are imported except for water
convolvulus which can be produced domestically and even for export. Most of
vegetable growers get seed from seed dealer shops which are closest to their
farms at prices which are not significantly different from other dealers
within the province.
The seed quality testing results show that leafy vegetable seeds are
of good quality meeting the minimum standard for seed required by the
National Seed Laws of Thailand. Most seeds are sold in can containers.
Labeling is incomplete and unclear; vegetable growers cannot determine either
variety name or testing date. About half of total respondents checked expiry
date before buying seed. However, few vegetable growers check germination
percentage of seed before sowing. |
