Asparagus, Enhance Output & Raise Quality – Vietnam

In open-field asparagus cultivation in Vietnam, the timing of fertilisation and crop protection is essential in
ensuring optimal productivity during an entire harvesting period, which can extend to 3 years over the plant’s lifecycle. This trial
was conducted in Tien Giang Province on Thai variety asparagus over 180 days with three sprays of OCC colloidal nutrients
in conjunction with crop protection mixes that consisted of insecticides and fungicides.

The trial’s objective was to assess if
OCC colloidal nutrients can improve the yield of asparagus. Growers did not reduce dosages of the insecticides and fungicides
due to the unpredictable environmental condition. Agriculture engineers from Vinafood II, the company that exports the
asparagus, tabulated yield results after harvest.
