Phophorous - Nutrient management in Rice


Deficiency Symptom

The major visual deficiency symptom is that the plants are dwarfed or stunted. Under severe deficiency conditions there is also a tendency for leaves to develop a blue-gray luster. In older leaves, a brown netted veining of the leaves may develop.


Growing of green manures or application of FYM @15-20 t/ha repeatedly for several years may meet out the phosphorus requirement of the organic rice crop. In case of acute  P deficiency as in hills, application of Rock Phosphate @ 5q/ha once in three years may take care of phosphorus nutrition of the organic rice in addition to application of FYM.
