It is a practice of land management to grow vegetables, fodder and fish
right in the center of rice fields. This
technology relies on crop rotation and nutrient management beyond restricting
pest movement from one vegetable plot to another because of the fodder and rice
in between them. The raised bed helps to reduce the salinity problem in
degraded land & water
Area Requirement for the model: One-hectare area
Enterprise and area allotment: It involves making of raised broad beds
and sunken furrow alternatively. low area is utilized for growing rice long
duration paddy cum fish (grass carp / singhi/magur) can be practiced in furrows
and the raised bed area for growing of seasonal vegetable or fodder crop during
monsoon season.
Income: Initial cost of
establishment is Rs
45000/ha, and provide net return of Rs 1.2 lakhs/ha/year and B:C ratio: 4.78.
The gross water productivity and net water productivity of the system is 8.96
Rs/m3, and 6.9 Rs/m3 Cropping
intensity: 300% in the beds and 200% in the furrows
