Abstract: Maize is a staple summer crop grown in the hilly areas of Nepal, where the soil is fragile and fertility is declining over years due primarily to degradation of natural resource base, high rates of soil erosion, increased cropping intensity and inadequate replenishment of soil nutrients. Forum for Rural Welfare and Agricultural Reform for Development (FORWARD) with the financial support from Hill Maize Research Program (HMRP/CYMMIT) conducted eight Integrated Plant Nutrient Systems (IPNS) trials, 16 Farm Yard Manure (FYM) improvement demonstrations and 16 conservation farming demonstrations each year through two women farmer groups since 2003 in Makawanpur District in order to raise the awareness of farmers on sustainable soil management practices through better utilization of locally available and external resources. The three years' trial results revealed that the maize crop with IPNS (15 t ha-1 FYM + 60-30-30 NPK kg ha-1) was better with respect to crop vigor and grain yields compared to the control treatment (farmers' practice with FYM and urea top dressing). The Improved cultivar with IPNS practices increased the grain yield by 64% (p
