Spinach cultivation

Dear Members,

Good Morning!!!

I am cultivating spinach at around 0.5 acres. The problem I am getting is late produce of spinach. It takes 22-25 days to produce.
The method I am applying: FYM+DAP+MOP during preparation of bed.
After 7-8 days I apply urea.

Please let me know if I can get production in 15 days to get profitable.
Shall I apply any micro-nuetrients?
