Maasrot, Chapter One, Mishnah Three
This mishnah continues to teach when various types of produce become liable for tithes. Again, since it is self-explanatory, there are no comments below.
1) Carobs [are liable to] tithes after they form dark spots; similarly all black fruits after they form dark spots.
2) Pears and crustumenian pears, quinces, and medlars [are liable to tithes] after their surface begins to grow smooth; similarly all white fruits, after their surface begins to grow smooth.
3) Fenugreek [is liable to tithe] when the seeds [can be planted and] will grow.
4) Grain and olives after they are one-third ripe.
