Nitrogen deficiency vs. optimum-Rice

Change crop

Nutrients

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.

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
