In the present investigation, it has been attempted to ascertain the impact of
Land Resource Inventory (LRI) for evaluating bio-physically viable and
economically acceptable alternate agricultural Land Use Plan (LUP) in Upper
Brahmaputra Valley eco-system of Assam, India. The study area is situated in
North West Jorhat Development Block, Jorhat district, Assam. Based on soil
survey and satellite image database, 4 landforms, 10 land use/land covers, 18
Landscape Ecological Units (LEUs), 12 soil series and 8 Land Management
Units (LMUs) were identified for management intervention in the study area.
Soil-site suitability for crops was ascertained in each land management unit
for specific crops grown in the region based on site and soil characteristics.
The studies revealed significant impact of LRI on LUP in terms of crop
productivity and net return. The average yield of crops, along with annual
net returns and benefit to cost ratios increased by 108, 85.9 and 33% when LRI
based LUP was employed with respect to traditional system of cultivation.
The same were increased by 304, 249 and 87.9% when LRI based LUP was
adopted with crop specific Customized Recommended Management
Practices (CRMPs) based on the need of the local conditions. The present
investigation unfolds a novel approach of LUP using LRI base LMU as a base
and can be exercised in other parts of North Eastern states of India under
similar agro-ecological environment.
