Good technology of seed storage will give advantage for farmer and
merchant because it can increase the economic value and seed viability. The
research aims were 1) to determine the effect of seed storage and nursery methods
to the growth and yield of Japanese bunching onion and 2) to determine the
optimal seed storage and nursery methods to increase the productivity of
Japanese bunching onion. The research was composed in two activities. First, the
laboratory research was designed in completely randomized design (CRD) single
factor with three treatments, namely the seed storage methods with fumigation,
silica gel, and aluminum foil. Second, the field research was designed in
randomized complete block design (RCBD) factorial with three blocks as
replication. The first factors were the nursery methods, namely bed and polybag
nursery methods. The second factors were the seed storage methods, namely the
seed storage methods with fumigation, silica gel, and aluminum foil. The
observations were on several variables of seed germination, growth and yield of
onion leaf. Data were analyzed with Analysis of Variance (ANOVA) at 5% level,
and continued with Duncan's Multiple Range Test (DMRT). The results showed
methods of fumigation, silica gel and aluminum foil methods could be used in the
storage of Japanese bunching onion seed. Japanese bunching onion seed nursery
using polybag nursery method produced higher seedling vigor at the time of
transplanting and provided higher yield when compared to bed nursery method
