When there are two containers of produce, one containing terumah and one containing ordinary produce and it is not known [which contains the ordinary produce and which contains the terumah], if [the contents of] one of these containers falls into ordinary produce, [the mixture] is not considered as miduma. [This same law applies if produce that is] terumah fell into one of two containers [of ordinary produce], but one does not know which one and afterwards, one of those containers fell into ordinary produce. Similarly, if one sowed [the grain from] one of the two containers, the produce that grows is considered as ordinary produce with regard to all matters. [The produce in] the remaining container is considered as terumah. If [the contents of] the second container fell into other produce, [the mixture] is not considered as miduma. Similarly, if another person sowed [the contents of] the second container, the produce that grows is considered as ordinary produce. If [the contents of] both containers fall into one mixture of other produce, the mixture is considered miduma according to the amount of produce in the smaller container. If one person sowed both of them, if the produce is a species where the seed decomposes, the produce that grows is considered as ordinary produce.If the seed does not decompose, the produce that grows is miduma. When does the above apply? When one sowed [the contents of] the second container before the first batch of produce was harvested. If, however, he harvested the first batch of produce before sowing the second, the produce that grows is considered as ordinary produce even when the seed does not decompose. [The rationale is that] produce that has been reaped and produce that is growing are not considered as indicators of each other's status.
