Part I            Registrant Information

Full Name of Registrant: SENECA FOODS CORPORATION

Former Name if Applicable: N/A

Address of Principal Executive Office:  3736 South Main Street
                                        Marion, New York 14505


Part II           Rules 12b-25(b) and (c)

If the subject report could not be filed without  unreasonable effort or expense
and the  registrant  seeks  relief  pursuant to Rule 12b- 25(b),  the  following
should be completed. (Check box if appropriate). [X]

        (a)      The reasons described in reasonable detail in Part III of this
                 form could not be eliminated without unreasonable effort or
                 expense;
        (b)      The subject annual report, semi-annual report, transition
                 report on Form 10-K, Form 20-F, 11-K or Form N-SAR, or portion
                 thereof will be filed on or before the fifteenth calendar day
                 following the prescribed due date; or the subject quarterly
                 report or transition report on Form 10-Q, or portion thereof
                 will be filed on or before the fifth calendar day following
                 the prescribed due date; and
        (c)      The accountant's statement or other exhibit required by Rule
                 12b-25(c) has been attached if applicable.

Part III          Narrative

State below in  reasonable  detail the  reasons  why Form 10-K and Form  10-KSB,
20-F,  11-K, 10-Q and N-SAR,  or the transition  report or portion thereof could
not be filed within the prescribed period.

Due to the  transition of the  registrant's  401-k  service  provider to a third
party for the  recordkeeping  purposes during the year, the  registrant's  401-k
service provider was unable, without unreasonable effort and expense, to prepare
its  accounting   records  and  schedules  in  sufficient   time  to  allow  the
registrant's   accountants  to  complete  its  review  of  the  401-k  financial
statements  for the period ended December 31, 2003,  before the required  filing
date for its Form 11-K.
