 After several collapsing, I have such a data,

 ID      Seed    Fert    x
 1       good    mamure  3
 1       good    chem.   4
 1       bad     chem.   2
 1       bad     manuure 1

 But I need to further collapse to:
 ID   x_good_maure       x_good_chem   x_bad_manure  x_bad_chem

. gen foo = Seed + "_" + subinstr(Fert,".","",.)

. drop Seed Fert

. ren x x_

. reshape wide x_, i(ID) j(foo) string
<output omitted>

. li, ab(14)

     +--------------------------------------------------------------+
     | ID   x_bad_chem   x_bad_manure   x_good_chem   x_good_manure |
     |--------------------------------------------------------------|
  1. |  1            2              1             4               3 |
