MISHNAH: m.MQ.1.3R. Eliezer b. Jacob [T2 or T4] says: water may be drawn from [one] tree to [another] tree, provided the whole field is not watered in this way. Seeds that have not had [any] drink before the festival week may not be watered during the festival week. The Sages however allow it in both the one case and the other.
GEMARA: [Not...the entire field]. Said Rab Judah [BA2], If the field has a clayey soil he may [water it]. It is likewise taught: When they said that it is forbidden to water them during the festival [week], they referred only to seeds that had not drunk before the festival; but seeds that had drunk before the festival may [again] be watered during the festival [week]; and if the field was a clayey soil, it is allowed [to water it]. And a bare field is not watered during the festival [week]; but the Sages allow it in the one case and in the other. Said Rabina [BA6]: You may infer from here that a garden plot may be sprinkled in the festival week. For in the case of a bare field, why is it [permitted]? Because it just quickens a tardy soil; here too, it just quickens a tardy soil.
Our Rabbis taught: `A white field may be sprinkled in the sabbatical year, but not during the festival [week]`. But it has been taught: It may be sprinkled either in the sabbatical year or during the festival [week]? Said R. Huna [BA2 or PA4], This [discrepancy] is not difficult [to explain]; the former [quotation] states the view of R. Eliezer b. Jacob [T2 or T4] and the latter that of the Rabbis.
Another [Baraitha] taught: A white field may be sprinkled in the pre-sabbatical year so that the greens may sprout in the sabbatical year. Nay, more, a white field may be sprinkled in the sabbatical year, so that the greens may sprout [better] in the post-sabbatical year.
