EFFECT OF ZINC AND MOLYBDENUM ON THE GROWTH AND YIELD OF GARDEN PEA

Abstract

The experiment was conducted at the farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka, Bangladesh during the period from December, 2015 to March 2016 to study the effect of zinc and molybdenum on the growth and yield of garden pea. The variety BARI Motorshuti-1 was used as the test crop. The experiment comprised of two factors as, Factor A: Levels of zinc (3 levels)- Zn 0 : 0 kg Zn/ha (control), Zn 1.5 : 1.5 kg Zn/ha, Zn : 3.0 kg Zn/ha and Factors B: Levels of molybdenum (3 levels)- Mo 0 3.0 : 0 kg Mo/ha (control), Mo 0.3 : 0.3 kg Mo/ha, Mo : 0.6 kg Mo/ha. The two factors experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. In case of different levels of zinc, the tallest plant (62.08 cm), maximum number of pods/plant (19.96), the highest green pod yield (8.41 t/ha), the highest stover yield (9.79 t/ha) was recorded from Zn 0.6 , whereas the shortest plant (56.76 cm), the lowest green pod yield (7.39 t/ha), the lowest stover yield (8.49 t/ha) was found from Zn 0 3.0 . For different levels of molybdenum, the tallest plant (61.41 cm), the highest green pod yield (8.31 t/ha), the highest stover yield (9.69 t/ha) was found from Mo , while the shortest plant (57.18 cm), the minimum number of pods/plant (17.29), the lowest green pod yield (7.59 t/ha), the lowest stover yield (8.69 t/ha) was recorded from Mo 0.6 . Due to the interaction effect of different levels of zinc and molybdenum, the tallest plant (65.50 cm), the highest green pod yield (8.91 t/ha) and the highest stover yield (10.65 t/ha) was found from Zn 3.0 Mo 0.6 0 and the shortest plant (53.85 cm), the minimum number of pods/plant (14.20), the lowest green pod yield (6.68 t/ha) and the lowest stover yield (8.18 t/ha) was found from Zn 0 Mo . Application of 3.0 kg Zn/ha & 0.6 kg Mo/ha and 1.5 kg Zn/ha & 0.3 kg Mo/ha showed statistically same green pod yield. So, 0 combination of 1.5 kg Zn/ha & 0.3 kg Mo/ha can be more beneficial for the farmers to get better yield from the cultivation of garden pea.
