Rice - Chlorosis

Symptoms
Starting from the tips, emerging leaves show progressing chlorosis. Plant size is reduced. Often the leaf tips are white and rolled. Severe deficiency results in necrosis and subsequent death of the growing point. If rice is affected by B deficiency during panicel formation, the plants may fail to produce panicels.

Reasons
Boron deficiency

Rice - Growth retardation

Symptoms
The complete root system is stunted and looks darker, less vigorous compared to the healthy variant.

Reasons
Boron deficiency on roots

Boron deficiency vs. optimum made worse by

  • Sandy soils
  • Alkaline soils
  • Soils low in organic matter
  • High levels of nitrogen
  • High levels of calcium
  • Cold wet weather
  • Periods of drought

Boron is important for

  • Strong tillering
  • Good grain set
  • Good grain fill
  • Improved yield
  • Healthy root system
