Abstract:
Seven different fertilizer combinations on cropping system basis were studied to develop a fertilizer package for mustard-boro rice-transplant aman rice cropping system. Significantly higher grain yield of mustard, boro rice and transplant aman rice were obtained when the recommended rate of fertilizer was applied. When P or K was not applied in boro rice after full NPKS application in the preceding mustard, gave similar yield to when received its recommended dose but when P or K was not applied for two consecutive boro (spring rice) and transplant aman rice (monsoon rice) it significantly reduced the transplant aman rice yield indicating that P or K had residual effect up to one succeeding crop. On the other hand, transplant aman need an extra application of both P and K fertilizer. Sulfur had a residual effect up to two succeeding crops if applied in full dose along with NPK in the preceding mustard. After application of full recommended dose of NPKS in the preceding mustard, a reduced (50%) dose of P + K along with a full N in the succeeding boro and transplant aman rice gave a similar yield to when recommended NPKS or NPK was used. To maintain soil fertility and to sustain crop yield this fertilizer practice may be considered as a good alternative compared to recommended fertilizer dose.
