Effect of Nitrogen Supplied from Manure and Fertilizer on the Growth, Yield and Nutrient Uptake of Rice

ABSTRACT

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.
