Abstract
Though Pea is considered as one of the most important winter vegetable belonging to leguminoseae family is also very much
prune to weed infestation. A study was conducted to observe the effect of various weed management techniques on weed
density, plant growth, yield and yield contributing traits of pea. The experiments were laid out in Randomized Complete
Block Design with six treatments replicated thrice. During 2011-12, the earliest germination (5.33 days) took place in plots
where black plastic and transparent plastic were laid out as mulch, followed by control and hand weeding plots (6.33 days).
The significantly tallest plants (65.57 cm), lowest weed density (13.43 m2
), minimum fresh weed biomass (35.72 g/ m2
),
lowest dry weed biomass (12.54 g/ m2
), maximum number of pod per plant (21.03), the longest pods (7.54 cm), the highest
weight of fresh pods per plant (44.17 g), number of gains per pod (8.02) and 100-grains weight (50.73 g) were recorded in
hand weeded plots. Hand weeding recorded substantial increase in pod yield (8.63 t ha-1
) which was significantly the highest
from all other treatments. In 2012-13, the significantly highest number of days taken to 50% flowering (65.33) was recorded
in plots covered with white plastic. The lowest weed density (14.20 g/m2
), least fresh weed biomass (42.32 g/ m2
), the
lowest dry weed biomass (15.19 g/ m2
), maximum number of pod per plant (14.76), the highest weight of fresh pods per
plant (44.17 g), the longest pods (6.97 cm), maximum number of gains per pod (6.43) and the highest 100-grains weight
(52.06 g) were recorded in hand weeded plots. Significantly the highest pod yield (7.66 t ha-1
) was also recorded in hand
weeding. It was concluded that during both the years, hand weeding surpassed all other techniques in minimizing weeds
density, weeds fresh and dry biomass enhancing all other growth and yield parameters followed by transparent plastic mulch,
black plastic mulch, Dual Gold and Stomp
