Major Cropping Systems
and Their Management

nsertion of an additional crop before, after or during the main
kharif rice or together with it, with the attendant management
schemes appropriate to specific cropping patterns and management
capabilities of farmers is expected to result in crop intensification and
increased farm profit. Current work in eastern India focuses on identifying
better crop genotypes for the existing cropping patterns as a whole rather
than dealing with each crop separately. Likewise, different crop
combinations and their management practices are also being investigated to
compare their economic viabilities.
Cropping systems
Mixed cropping
The surveys reveal that the most common rice-
based mixed cropping combinations farmers use
are wheat + mustard, gram + mustard, wheat +
barley, wheat + linseed after rice in lowland
situations, and rice + pigeonpea, rice + green
gram, rice + black gram, rice + sesamum, pigeon-
pea + black gram, pigeonpea + sorghum, and
pigeonpea + sunhemp in upland situations. Early
rice + maize, or moong, or sesamum before flood
and jute + rice mixed cropping during flood are
common in deepwater areas.
