You need something like this:

SQL> SELECT JSON_OBJECT (
  2  'agri_Expense' VALUE
  3      JSON_OBJECT ('abc' value
  4                      JSON_OBJECT( 'input' VALUE 10, 'max' VALUE 20, 'check' VALUE 30),
  5                   'xyz' VALUE
  6                      JSON_OBJECT ( 'income' VALUE 19800 ))
  7  )
  8    FROM DUAL;

JSON_OBJECT('AGRI_EXPENSE'VALUEJSON_OBJECT('ABC'VALUEJSON_OBJECT('INPUT'VALUE10,
--------------------------------------------------------------------------------
{"agri_Expense":{"abc":{"input":10,"max":20,"check":30},"xyz":{"income":19800}}}

Update :

SQL> SELECT
  2  JSON_OBJECT ('abc' value
  3                  JSON_OBJECT( 'input' VALUE 10, 'max' VALUE 20, 'check' VALUE 30),
  4               'xyz' VALUE
  5                   JSON_OBJECT ( 'income' VALUE 19800 ))
  6    FROM DUAL;

JSON_OBJECT('ABC'VALUEJSON_OBJECT('INPUT'VALUE10,'MAX'VALUE20,'CHECK'VALUE30),'X
--------------------------------------------------------------------------------
{"abc":{"input":10,"max":20,"check":30},"xyz":{"income":19800}}
