Nutrient Management :

• Soil fertility status and proper nutrient management for maximum yield per unit area.
• Low soil fertility is a major limitation of rice production.
• Major minerals nutrients for rice plants are N , P₂O_5, and K₂
• The main problem of fertility degradation is due to N loss. Only 25-50 % N is used by crops.
• INM to maintain soil health.

Manure and fertilizer recommendation :

• Depends upon fertility strains of soil, previous crop growth, planting time, variety used, etc.
• Recommendation is done after lab test.
• For improved variety: 100:30:30
• For local variety: 40:30:30
• Organic manure 6-10 tons per ha. Is generally recommended for improved as well as local variety.

Application time :

• Organic manure is applied and incorporated in the soil 15-30 days before planting.
• All phosphorus, potassium, and half dose of N recommended for rice should be applied and incorporated in the soil before planting or
• The other half dose of N is split into 2 doses.
• ¼ this applied as a top dressing 20-30 days after planting or
• ¼ th is applied 40-50 days after planting or transplanting. The early tillering stages and panicle initiation stage are the best time for applying N fertilizer.
