Abstract
Spring onion (Allium fistulosum L.) is a popular salad vegetable produced
widely over the world, including in Vietnam. Thanks to its flavor and aroma,
it is an indispensable ingredient used to flavor soups and other dishes.
Vermicompost is a natural and environmentally friendly fertilizer used
widely to increase crop production and maintain the sustainability of
agrosystems. Consequently, this study was conducted to investigate the
efficiency of vermicompost at different application rates in promoting the
growth and yield parameters of spring onion. The results show that adding
vermicompost to spring onion production had significant positive effects on
plant height, number of leaves, number of tillers, individual plant weight,
and plot yield. Particularly, the application of vermicompost at 40 t ha-1
showed the highest performance in the observed parameters, increasing the
number of leaves, number of tillers, individual plant weight, and plot
yields to 64.78, 21.18, 302.96 g plant-1, and 4.86 kg m-2, respectively. The
plot yields in the treatments of the highest and lowest vermicompost
application increased by 49.1% and 3.9%, respectively, in comparison to the
control. Consequently, there was a strongly positive relationship between
the application rate of vermicompost and the plot yield.
