Abstract
An experiment was conducted to evaluate the effects of NAA (0, 25, 50 ppm) at varying nitrogen levels (0, 50, 75, 100 % of the recommended dose) on nitrogen (N), phosphorus (P) and potassium (K) uptake by shoot and root and percentage of total NPK uptake by BARI Gom-26 at flowering and grain filling stage. Application of NAA at varying nitrogen levels had significant effect on P and K uptake by shoot and root at both stages, whereas, the N content of shoot at flowering stage and of root at the grain filling stage were non-significant.At both the stages, K content of root increased following all the treatments. At flowering and grain filling stage, P content of root and shoot increased and decreased due to different treatments. The maximum percentage of total NPK uptake was recorded from K followed by N and P respectively at both stages. In majority cases there was a decreasing trend in percentage uptake of N and P at grain filling stage compared with flowering stagewhereas, the trend was almost reverse in case of K. The N content of grain increased following all the treatments, the maximum being due to 25 ppm NAA in combination with 75 % N-fertilizer. Only decrease in P content of grain was recorded when 25 ppm NAA without any N-fertilizer was applied. In case of K content, 50 ppm NAA without any N-fertilizer resulted the only decrease. The highest nitrogen use efficiency (NUE) by total plant was also recorded from 50 ppm NAA in combination with 50 % N-fertilizer at flowering stage, whereas, from 25 ppm NAA in combination with 75 % N-fertilizer at grain filling stage.J.
