The fertilizer adjustment equation developed for cotton has been test verified to give rationalised fertilizer recommendation for getting maximum profit. The experiment has been conducted on typic chromustert with cotton MCU 5 and MCU 9. The treat- ments consisted of an absoluta control, blanket recommendation and fertilizer recom- mendation for yield targets 20, 25 and 30 q/ha based on soil test value. Cent per cent achievement was obtained up to 25 q/ha yield target. The 't test revealed that the equa tion holds good for yield targets up to 25 q/ha. Both yield and profit were maximum for 25 q/ha in both the varieties. The quality parameters except ginning percentage did not vary significantly. The post-harvest soil analysis showed a considerable reduc tion in available K compared to available N and P.
