3 Types of multiple Cropping
A. The agronomist Darmpal classified it is the following ways
It is the growing of same crop in the same field in a year. e.g. rice after rice, jute after jute.
2 types of crops are grown alternately in every year in a piece of land. e.g. Jute after vegetable, Rice after vegetable.
It is the combination of more than 2 types of crops grown in sequence in a piece of land in a year.
B. Also types as
1) Pure stand multiple Cropping
It is a multiple in which the crops are grown successively in a definite period of time of the year in the unit of land, possessed by farmers. In this Practice each crop sown and harvested separately with independent land preparation for each crops. e.g. Aus paddy → T. amon → Lentil.
2) Mixed type of multiple cropping
It is that kind of multiple cropping in which two or more crops are grown concurrently and mixed together in the same season and in the same piece of land. In mixed cropping one crop is harvested after another depending on their maturity period. E.g. Aus+B. amon, Mustard+lentil, Barley+Rai.
3) Intercrop type of multiple cropping
It is a kind of multiple cropping, in which same minor crop are grown in between the space of major crops in alternate pattern. e.g. In between two rows of sugarcane, lentil can be sown.
4) Relay type of multiple cropping
In this system of multiple cropping, the second or minor crop is sown shortly before the harvest of major crops. e.g. Sowing of seeds of khesari in the field of T. amon, sowing of seeds of watermelon in Rice field.
