A pot culture study was conducted in 20 acidic soils of Senapati District of Manipur, India during rabi season of 2013-14 to estimate the critical limit of P in soil and pea plant for predicting the response of pea (Pisum sativum L.) to P application as well as to study the effect of P application on dry matter yield and uptake of nutrients in pea crop. The experimental soil was acidic in nature, electrical conductivity of the soil was in safe limit for crop growth. The organic carbon status was almost high and soil was clay in textural class. Pot culture studied showed that the application of phosphorus @ 60 kg P2O5 ha-1 significantly superior (85 %) of the studied soils to any other treatments and 40 kg P2O5 ha-1 was significantly (15 %) to the total soils in dry matter yield of Pea variety Arkel. The critical limit of the P concentration in the pea was found 0.42 per cent. It was revealed that the critical level of phosphorus in the soils for growing of pea plants varied with the methods of phosphorus extraction. The critical level of soils ranged from 14.30 to 25 kg P2O5 ha-1 depending upon the methods of phosphorus extraction.
