Shabbat 85: Circle and Square Models to Plant Vegetables in Fields

The rabbis continue to discuss how fields should be treated regarding different crops.  They recommend different measures between seeds when they are planted.  Beyond that, they recommend that the same kind should be planed at east the width of a foot apart.  The rabbis also consider the shape of the land being planted.  

We are told about the many ways that crops can be planted within the given shape of the land. Within rows, circles, squares of different sizes can be allotted to one's field.  The rabbis even come up with a creative way to use as much space as possible in the field through imposing 'circles' upon square-shaped beds of at least six by six handbreadths.  Different rabbis believe that different numbers of vegetable varieties are permitted in each set field.
