The paper investigates an innovative extension approach of generation and distribution ofLand Resource Cards, developed from Land Resource Inventory database, used for site-specific farm resource management in watersheds adopted under World Bank funded Sujala-III project. Extent of reach, satisfaction level and training status of Land Resource Cardsin 12 model micro-watersheds located in different agro-climatic regions of Karnataka witha sample size of 720 farmers was assessed. The Land Resource Cards reached only 18 percent of farmers while 22 per cent of farmers were trained for its utilization. However, 77per cent were satisfied with the information provided and 23 per cent suggested for furtherimprovement in cards for greater utility. The overall farmer’s perception on capacity buildingon land resource cards revealed that they were very useful in farm-level resourcemanagement. Hence, need for replication of similar approach in all database drivenwatersheds to be implemented in the future with adoption of modifications is suggested.

Soil and water conservation along with crop productivity improvement is indispensable for sustainable development of rainfed areas. Integration of suitable fruit trees within the cropping system can reduce risk allied with rainfed farming. The system of raising multi-height plant species with agricultural crops known as multitier agroforestry system was assessed (2007)(2008)(2009)(2010) for resource conservation and production potential in rainfed conditions of Eastern Ghats region in India. Thirty experimental plots, each of 18 9 12 m dimension with 2 % slope having different multitier agroforestry treatments were assessed for soil erosion, nutrient loss and crop yield. Results revealed that multitier plantation of drumstick (Moringa oleifera) with Gliricidia sepium hedgerow and ginger (Zingiber officinale): pigeonpea (Cajanus cajan) (8:2) intercropping enumerated minimum mean runoff (8.26 %) and soil loss (3.45 Mg ha -1 ). This treatment saved 74 % more soil organic carbon, 64 % more phosphorus and 66 % more potassium, respectively than broadcasted finger millet cultivation (traditional farmers' practice). An increase of 24-27 % drumstick fruit yield was observed in Gliricidia hedgerow based multitier agroforestry systems over non-Gliricidia systems. The findings will contribute as a technical reference for the promotion of hedgerow based multitier agroforestry for resource conservation and fertility restoration of sloping lands.
