I have grown these sunflower seedling in bubble tray and I want to get suggestions, at how many days after showing, I need to transplant them in the field.
Your seedlings suffer from etiolation, you can start transplanting now or two days later. Wish you luck.
Any time as long as they are protected from predators and adverse environmental conditions :)
In Iraq, it is sown in mid-February in spring and mid-June in autumn, It is also possible to transfer seedlings on an experimental level according to the researcher's need.
in algeria at the end of september beginning of october when the temperature drops in the north, transplantation is done. Since it is cells, the roots remain intact, the transplantation, whether on the ground or in plots, is done without risk.
I think, the transfer of sunflower plants is considered an uneconomical method at the production level. As for the transfer at the level of a field experiment, it is usually 15-20 days after germination.
Direct sowing is the general practice. Next time try to sow directly rather than transplanting. Transplant after 20 days after sowing. Plant should grow atleast 10- 15 cm. Plant will be in shock after transplantation. Water the plant immediately after transplantation.
generally, 2 to 3-leaf stage is suitable for transplanting. Small seedlings are more susceptible.
