An experiment was conducted in split-split plot design to study the effect of N, Zn and Fe application on N, P and K content in grain and straw and their total uptake in parmal rice crop. The results of the study showed that N and K content were significantly higher at 125% of RDN as compared to 75% of RDN both in grain and straw. Zn also had significant effect on N and K content; Zn4 and Zn2 were statistically at par with each other and were significantly higher than Zn3 and Zn1 which were also statistically at par with each other. P content was not affected by N, Zn and Fe application. Total N, P and K uptake by rice crop was significantly affected by N levels and Zn application methods but the effect of Fe on uptake of N, P and K was found to be non-significant.
