ການກຳໜົດຄວາມໝາຍ ຂອງເຕັກໂນໂລຢີ:

Growing of crops for food, fodder trees and fibre forest in a compact patch.

2.2 ການອະທິບາຍ ລາຍລະອຽດ ຂອງເຕັກໂນໂລຢີ

ການພັນລະນາ:

This technology has mainly to be applied on 5 Ha.of private waste land of poor farmers to increase production. This technology focuses on life fencing, planting of trees for both timber and food varieties, land development, water availability and green manuring. Three line bamboo plantation has been done by laying method at all along the boundary line. Agave also planted at boundary line to give additional protection. Then proper compartmentation has been done keeping intact the total area of individual land holders. Here 'V' ditches has been provided accross the slope of total land. Some fruit and fodder, forest trees were planted all along the bunds and inside the field. The density of tree plantation at crop field is less. So as to facilitate crop cultivation. Gullies has also been arrested by construction of gully control structures. One waterhole has been excavated for life saving irrigation. To manage field waste and to get green manure three compost pits also established.

Establishment / maintenance activities and inputs: After several meeting and interaction with village people, this technology has been established. All the land users where technology is applied were fully engaged for every construction work. So as to have a clear understaing of each small intervention. As this technology uses locally available materials, its maintenance by land users become easy.

Natural / human environment: Here Soil & Water Conservation has been given importance, hence more vegetative cover has been noticed in and around technology area. Increase of soil fertility has also been noticed. Complete barren land conveted in to crop land. So the technology has positive impact on the environment undoubtedly.

Major land use problems (compiler’s opinion): Due to slope and lack of vegetation cover, majority top soil were lost and many gullies also formed as a result there was no scope for cultivation.

Major land use problems (land users’ perception): The soil was hard, no fertility, land is slopy. So there was no scope for any kind of cultivation in the same patch of land.
