In a pot culture experiment, the response of French bean (Phaseolus vulgaris L.), cv. Contender to phosphorus (P) was studied on 20 acidic paddy soils of Thoubal district, Manipur. All the collected soil samples were acidic in reaction varied from 4.61 to 6.26 with mean value of 5.48, organic carbon content 9.9 to 24.1 g kg-1 , CEC 9.21 to 35.71 [cmol (p+ )kg-1 ] and clay content ranged from 24.78 to 73.38 per cent. Addition of P fertilizer in the soils significantly increased the dry matter production and P uptake by the crop.
