(Mishnah): If the end of a row entered into barley, it's permitted as it's apparent that it's the end of his field.
ùìå çéèéï åùì çáéøå îéï àçø îåúø ìñîåê ìå îàåúå îéï.
If he is growing wheat and his neighbor is growing another species, he may plant a row of that species at the border of his field (thereby avoiding the required separation of a Beis Rova between the fields).
ùìå çéèéí åùì çáéøå çéèéí îåúø ìñîåê ìå úìí ùì ôùúï åìà úìí ùì îéï àçø.
If he is growing wheat and his neighbor is also growing it, at the border he may make a row only of flax but not of another species.
øáé ùîòåï àåîø àçã æøò ôùúï åàçã ëì äîéðéï.
(R. Shimon): Both flax and other species are permitted.

(R. Yosi): Even in the middle of his field, he may test the soil using a row of flax.
âîøà øéù ì÷éù áùí çæ÷éä øàù úåø äáà îçåøáä îåúø.
(Reish Lakish citing Chizkiyah): If the end of a row entered another species but then the row itself became destroyed, it is still permitted.
àîø øáé éåçðï ìà ùðå àìà äéä øàù úåø äà øàù úåø äáà îçåøáä àñåø.
(R. Yochanan): The Mishnah only permitted it because the row was still in existence; otherwise it's forbidden.

(Chizkiyah): If a person has a field the size of a Beis Rova (50 by 50 Amos that is sown with barley) and any sized field next to it - that small field could act as the end of a row to plant in it any species.
àîø ø' éåçðï àéðå æåøò ìúåëå àìà îéï àçã ìáã.
(R. Yochanan): He may only plant the same species as in the large field.

(R. Zeira): R. Yochanan agrees that if it was 11/2 Beis Rova (each 1/2 Beis Rova can be viewed as a separate field and) he can plant half a Beis Rova on each side and the middle half a Beis Rova can be viewed like both. (He can plant section one with one species, section 3 with another species and the middle section is considered separate and cannot be planted with either species.)

Question (Baraisa against R. Yochanan): If a person had two fields, one sown with wheat and one with barley, it's permitted to place a furrow between them and plant one half of it wheat and one half barley, because the wheat looks like the end of the field of wheat and the barley looks like the end of the field of barley. What does R. Yochanan do with that Baraisa?
ôúø ìä ëø' ìéòæø áï éò÷á. ãø' àìéòæø áï éò÷á àîø àôéìå çéèä àçø çéèä ðëðñú ìúåê ùì ùòåøéï åùòåøä àçø ùòåøä ðëðñú ìúåê [ùì] çéèéï îåúø îôðé ùäçéèä àçø çéèä äðëðñú ìúåê ùì ùòåøéï çéèä åùòåøä [ãó é òîåã à] àçø ùòåø' ðëðñú ìúåê ùì ùòåøéï.

Answer: That Baraisa follows R. Eliezer ben Yaakov, who said that even a row of one wheat seed following after one wheat seed that enters into barley or vice-versa is permitted. But if there was just one wheat seed embedded in a field of barley or vice-versa, it is prohibited.
