  An investigation was undertaken to see the effect of added nitrogen supplied from poultry manure and urea-N on the growth, yield and nutrient uptake of BRRI Dhan 29 rice. There were eight treatments consisting of T0 (control), T1 (N100), T2 (PM5.0), T3 (N75 + PM1.25), T4 (N50 + PM2.5), T5 (N25 + PM3.75), T6 (PM7.5) and T7 (N120). Application of poultry manure alone or in combination with urea-N significantly increased the plant height, number of effective tillers hill-1, panicle length, number of grains panicle-1 and filled grains panicle-1 whereas 1000-grain weight varied insignificantly. The grain and straw yields increased significantly with different treatments and the highest yield was obtained with T6 treatment which was statistically at par with T5. The NPKS uptake was positively influenced by different treatments. Poultry manure was found the best source of N for rice. Application of poultry manure considerably increased the organic matter content, total N, available P, exchangeable K, available S and CEC of the post harvest soil and thus improved soil health.

  The field experiment was conducted in a silt loam soil to compare the effect of N, P and K fertilizers on the yield and nutrient uptake by rice and post-harvest soil properties. Seven treatments were T0 (control), T1 (Urea + Triple superphosphate + Muriate of potash), T2 (Urea + Diammonium phosphate + Muriate of potash), T3 (Urea + Triple superphosphate + Ash), T4 (Urea + Single superphosphate + Muriate of potash), T5 (Urea + Single superphosphate + Ash) and T6 (Urea + Diammonium phosphate + Ash). Application of fertilizers significantly increased the grain and straw yields of rice. Panicle length, effective tillers hill-1 and filled grains panicle-1 were also increased significantly due to application of fertilizers but the increase of 1000-grain weight was insignificant. Grain yield was highest with T3 (Urea + Triple superphosphate + Ash) treatment (5.46 t ha-1) which was followed by T1 (Urea + Triple superphosphate + Muriate of potash) treatment (5.30 t ha-1), while the lowest was in control. The grain yields were increased by 47.0 to 68.0% over control due to application of fertilizers. The results on straw yield reflected similar trend as in grain yield. Application of fertilizers caused a significant increase during NPKS uptake by rice. The application of fertilizers had a negligible influence on pH, CEC, organic matter, total N, available P, exchangeable K, and available S content of the post-harvest soils compared to their initial status.
