ITEM 2.02.  RESULTS OF OPERATIONS AND FINANCIAL CONDITION.

         On October 12, 2005, Monsanto Company issued a press release announcing
its fourth quarter and fiscal year 2005 financial and operating results for the
period ended August 31, 2005. This press release, as well as the fourth quarter
and fiscal year 2005 unaudited supplemental data, are furnished as Exhibits 99.1
and 99.2 hereto, respectively, and incorporated herein by reference.

         The press release furnished herewith uses the non-GAAP financial
measure of earnings per share ("EPS") on an ongoing basis. Our ongoing EPS
financial measure excludes certain after-tax items that we do not consider part
of ongoing operations, which are identified as such in the reconciliation. We
believe that our ongoing EPS financial measure presented with these adjustments
best reflects our ongoing performance and business operations during the periods
presented and is more useful to investors for comparative purposes. In addition,
management uses the ongoing EPS financial measure as a guide in its budgeting
and long-range planning processes, and as a guide in determining incentive
compensation. The presentation of EPS on an ongoing basis is intended to
supplement investors' understanding of our operating performance. This non-GAAP
financial measure may not be comparable to similar measures used by other
companies.

         We are furnishing the information contained in this report, including
the Exhibits, pursuant to "Item 2.02 Results of Operations and Financial
Condition" of Form 8-K promulgated by the Securities and Exchange Commission
("SEC"). This information shall not be deemed to be "filed" for the purposes of
Section 18 of the Securities Exchange Act of 1934 ("Exchange Act") or otherwise
subject to the liabilities of that section, unless we specifically incorporate
it by reference in a document filed under the Securities Act of 1933 or the
Exchange Act. By filing this report on Form 8-K and furnishing this information,
we make no admission as to the materiality of any information in this report,
including the Exhibits.
