Manure: Apply 5 tones FYM or Compost or 5 quintal Karanj or Neem cack per ha in direct seeded rice or before 15 days after transplanting. Karanj or Neem cack are also effective in controlling nematodes in field. Integrated Nutrient Management for Rice: INM approach is required to ensure higher yield. As for as possible, apply fertilizer as per soil test recommendation. If it is not followed, adopt blanket recommendation as follows in Jharkhand state. All P2O5 and K2O should be applied as basa

2. Medium land ecosystem
3. Low land ecosystem
1. The state is divided into the three rice sub zones. In General, the plateau region of Chotanagpur and Santhal Parganas is characterized by humid and sub humid tropical monsoon in sub zone IV, sub humid to subtropical in sub zone V and humid to sub-tropical in sub zone VI, undulating Plateau, hills and mountains, non existence of perennial rivers, initially high forest cover, which is depleting fast due to mineral and industrial exploitation and encroachment, concentration of tribal population
The state has been divided into 3 agro-climatic sub zones viz.,
Central and North eastern plateau sub zone, Western plateau sub zone and South eastern plateau sub zone. The soils are laterite, red-yellow loams, red sandy / gravelly type.
