and are perfect for chickpea production. More areas under the marginal zone
were rainfall is between 300-350 mm could be added to this area, Also, areas with
a slope between 9 and 15% could be used for chickpea production (but the
statistics in the tables do not consider these areas).
The crop rotation for rainfed areas which receive rainfall exceeding 300 ram, is
