Abstract
[116.18.012:225:145.71]In pot experiments P32 in the form of superphosphate was applied to a calcareous red soil and to a non-calcareous red soil at rates of up to 120 kg/ha. Eleusine coracana was the test crop. "A" values maintained the same trend as soil test values for available P; they were higher at the 35th day after transplanting than at the post-harvest stage; they remained almost constant irrespective of the rate of P application. On both soils the dry matter yield at the 35th day after transplanting depended on added fertilizer P to the extent of 68 and 78% respectively. The contribution of soil available P to the dry matter yield was not significant at this stage for either soil. Nor was there a significant relationship between total yield (grain + straw) at the final stage and added P or available P
