Abstract


Test verification trials with rice-IR. 20, IR. 50, Bhavani, Co. 43, Ponni and Paiyur-1 were conducted in sixteen sites on Noyyal alluvium (Typic Haplustaff) in TNAU Farm/ farmer's holdings in Coimbatore by adopting fertiliser prescription based on the new concept of "Fertilicer Prescription Procedure for specific yield targets".. The results indicated that the fertiliser prescription based on the new concept fitted well with the yield targets up to 50 q/ha, while the fertiliser prescription for 45 g/ha of yield target. recorded the highest value cost ratios, (VCR). The post-harvest soll analysis from these plots also showed that there was no appreciable decline in the fertility status by follow- ing this approach.
