Abstract


Traditional transplanted rice production is not an economic business in Meghalaya. Hence, farmers are promoted to grow the direct seed rice organically. But the phosphorus deficiency is a major yield-limiting factor in direct-seeded upland production in Meghalaya. Hence, integrated phosphorus management must be taken into account for fetching a higher economic yield of upland rice in acidic soils of Meghalaya. Equal substitution of farmyard manure (FYM), vermicompost (VC), and poultry manure (PM) (FYM-25% + VC-25% + PM-25%) along with the Phosphorus Solubilising Bacteria is the economically feasible practice for sustainable upland rice production in Meghalaya under organic management.
