Rice - Chlorosis
Symptoms
Starting from the tips, older leaves show progressing yellowing and subsequent light brown necrosis. Plant growth is sparse compared to the healthy variant.
Reasons
Nitrogen deficiency
Rice - Growth retardation
Symptoms
Starting from the tips, older leaves show progressing yellowing and subsequent light brown necrosis. Aerial plant growth is sparse compared to the healthy variant.
The root system is also less voluminous than normal, but longer.
Reasons
Nitrogen deficiency
Rice - Chlorosis
Symptoms
Starting from the tips, older leaves show progressing yellowing and subsequent light brown necrosis.
Reasons
Nitrogen deficiency
Nitrogen deficiency vs. optimum made worse by
- Low or high pH soils
- Sandy or light soils (leaching
- ) Low organic matter
- Drought conditions
- High rainfall (leaching) or heavy irrigation
- Addition or high levels of non-decomposed organic matter/manure (eg straw)
- Fast growing crops
Nitrogen is important for
- Healthy foliage
- Optimum photosynthesis
- Improves yield and quality
