(1)A perfected security right in crops or their proceeds given not more than six months prior to such crops becoming growing crops by planting or otherwise in order to enable the debtor to produce the crops during the production season, shall have priority over an earlier perfected security right in the same collateral, to the extent that the earlier interest secures obligations that were due more than six months prior to the crops becoming growing crops by planting or otherwise, even though the person giving value had notice of the earlier security right.
