| Abstract: |
A long term fertility experiment in rice-wheat rotation has been in progress since more than
a decade at RARS, Parwanipur. This report addresses the results · obtained after 15th
rice/wheat (1995/96) and 16th rice (1996/97) harvest.
The results indicated that the balanced use of NPK (100:30:30 kg/ha) along with Zn (ZnS04
@ 25 kg/ha) in rice and the same amount of NPK in wheat were the best combination in
respect to grain yield of both the crops. The effect of Zn in addition to NPK was found
nominal in case of rice but, the residual Zn with NPK markedly enhanced the yield of wheat.
The combined effect of NPK was highly significant over N, N+P and N+K in both rice and
wheat. The use of FYM along with 50 kg N/ha in rice and residual FYM plus NPK in wheat
showed the significant superiority over FYM alone. Regarding the effect of imbalanced use
of fertilizers, a fluctuated yield trend was observed. The soil analysis results showed an
increased organic carbon content and maintained soil P" value due to application of FYM
and chopped straw in each year. |
