Abstract:
An investivation was carried out to evaluate the effect of P levels on root
growth, dry matter accumulation, nutrient uptake pattern and yield of mnungbean
varieties at the research held of Shcr-c-Bangla Agricultural University. Slier-c liangla
Nagar. Dhaka during kharif IL season of 2006. Four varieties of mungbean (BAR!
mung-2. BARI mung-6. BU mung-4 and I3LN.A rnung-5) and four levels of
phosphortts (0. 9. IS and 27 kg P ha
4
) were the treatment variables. i'he experiment
was laid out in a split plot design with 3 replications. Varieties were randoml
arranged to the main plot and phosphorus levels in the sub plot. Plant growth. yield
and yield attributes were signihicantly influenced by dilièrent varieties. The highest
root growth, unal dry matter production, nodule number and dry weight were obtained
from the variety BU mung-4. higher pod length. pods plant''.
seeds
pod" and 1000
seed weight were also recorded lbr BU mung-4. [he highest seed yield was found in
131-1 mung-4. Over all performance of BU mung-4 was better than other three varieties
indicating the genetic superiority. The growth. yield and yield attributes increased
with increasing levels of P up to 27 kg
Application of 27 kg P ha'' gave the
highest yield and yield attributes which was similar to 18 kg I' ha''. The contents of
NPK in munabean stem. leal and seed varied significantly due to the variations in P
rates. Application of 27 kg P ha"
I
also gave the highest content of NPK. Variety l3L
mung-4 responded favorably to P I'ertilization upto 27 kg P ha" in terms of root
growth, dry matter. yield and yield attributes and it was statistically identical with 18
kg P ha". The experimental results suggest that application of 18-27 kg P ha" lbr RI.)
mung-4 would he needed for obtaining moderate yield on Grey Terrace Soil of ALL-
