Mild deficiency of P are usually characterized by stunted growth of plants with no very clear-cut leaf symptoms
Most severe deficiencies result in dark green leaves with a leathery texture, and reddish purple leaf and margins
About 25-50 kg P2O5/ha has been recommended for different groundnut-growing regions in the country.
It has been found that single super phosphate is the best source of phosphorus as it contains calcium (19.5%), sulphur (12.5%) and phosphorus (16%)

Phosphorus deficiency is a kind of disorderalong with inadequate supply of phosphorus. Phosphorus refers here means different salts of phosphates (PO43−), nonhydrogen phosphate (HPO42−), and dihydrogen phosphate (H2PO4−).
These anions readily internally react , and the predominant species is determined by the pH of the solution or soil. Phosphates are required for the biosynthesis and ATP, essential for life.
Phosphorus deficiency is controllable .It can be done byadministering sources of phosphorus such as :bone meal, rock phosphate, manure, and phosphate-fertilizers.
