Definition of the Technology:

Holistic demonstration includes integrated cultivation of Agri-Horti-Silvi technologies. Along with the Soil & water Conservation structures suitable to the site.

2.2 Detailed description of the Technology

Description:

Holistic demonstration was taken in the upper reach, middle reach and lower reach (2 hectares each) in a village in the watershed. The demonstration units includes soil & water consercvation structures also. Crop demonstration with integrated pest management, seed treatment, pitcher irrigation practices, varietal trails were implemented to increase the overall per capita income of the farmer. However, the suitable SWC was according to the site of lower reach/ upper reach or middle reach. The plot was accommodated with suitable field crops, horticultural species either on the bunds or in the fiels itself and some fodder crops, some forestry species etc.

Purpose of the Technology: The demonstration units now serve as the units of awareness brining in understanding the holistic approach and also to encourage the other farmers to replicate the same in their fields.

Establishment / maintenance activities and inputs: (1) site selection with concerned farmer, (2) design and preparation of estimates by the project staff, (3) discussion with the VWDC and community, (4) discussion regarding contribution with the farmer (5) layout and construction by the project staff with the contribution from the concerned farmers.

Natural / human environment: This technology was taken up in the semi arid condition and in the erratic rainfall condition.
