Abstract:
A field experiment was conducted at the Sher-e-Bangla Agricultural University Farm, Dhaka
1207, during the khari I' season of 2012 to study the" Effects of Phosphorus and Zinc on the
growth, yield and yield contributing characters of Mungbean (BAR! Mung-6)". The
experimental soil was loam in texture having pF! 5.71 and organic carbon content was 0.68%.
Four levels of phosphorus (0, 15, 20 and 25 kg P ha") and three levels of zinc (0, 1.5 and 3.0
kg Zn ha") were used in the study. Levels of these two nutrient elements made 12 treatment
combinations. The experiment was carried out in Randomized complete block design
(RCBD) with three replications. The results revealed that seed and stover yield of mungbean
increased with increasing levels of phosphorus and zinc up to certain level. Inease of P the
maximum significant seed yield (1.5 t hi') and stover yield (2.47 t ha") were obtained with
(25 kg P ha") and the minimum significant seed yield (1.11 t ha
1
) and stover
yield (2.06 t ha)
were obtained with the treatment P
0
(0 kg P ha"). Incase of Zn the
the treatment
p3
maximum significant seed yield (1.45 t ha") and stover yield (2.42 t ha") were obtained with
the treatment Zn
2
(3 kg Zn ha") and the mhimuni significant seed yield (1.27 t ha") and
stover yield (2.21 t ha") were obtained with the treatment Zn0 (0 kg Zn ha"'). The maximum
significant plant height (52.05 cm). number of branch plant" (2.87), seed yield (1.68 t ha"),
yield contributing factors like number of pods plant" (20.86), number of seeds pod" (12.65)
and weight of 1000-seeds (45.11 g) were obtained with the treatment combination P
2Zn 2 (20
kg P ha
-1
± 3 kg Zn ha"). On the other hand minimum seed and stover yields were obtained
with P0Zn9
(No P and No Zn) treatment combination. The N, P. K and S concentration of
(20 kg P ha" + 3 kg Zn ha")
treatment combination and again decreased with increasing phosphorus more than 20 kg P
mungbean plant increased significantly from control to P2Zn
2
S status of
postharvest soil significantly.
