Manure Production Infrastructure
Since 2005, intensive efforts are being made to make agriculture in Sikkim selfsustaining and self-sufficient by mobilizing effective utilization of on-farm waste. Strategies were drawn to develop necessary infrastructure for on-farm generation of vermicompost, enriched compost and liquid manure. Farmers were supported for construction of onfarm Vermi Compost Production units and Rural Compost-cum-Urine pit. Till 2008-09, 24536 Rural Compost-cum-Urine Pit and 14487 Vermi Compost units were constructed in farmers field. Eight vermiculture hatcheries were also established to ensure steady availability of live earthworms for vermicomposting

Biofertilizer Production unit
The Department is propagating the use of biofertilizers through demonstration at the farmers’ fields. A bio-fertilizer production unit was constructed during 2009 at Mazitar using the funds provided by NEC. The Unit is ready to produce biofertilizers and it will be in a position to meet the requirement of these fertilizers for use in various crops of the State useing native strains of bacteria.
Azolla has great potential as a green manure in low land paddy cultivation and capable of providing a minimum of 30 kg N/ha to maximum of 60 kgN/ ha under field condition. Thus, incorporation of Azolla in soil increases soil organic matter content and nitrogen availability to plants. During 2009-2010, 200 units of Azolla pond have been developed at farmers field benefiting 200 farmers. This will help in supplementing nutritional requirement of plants under organic condition.
