Two separate experiment were conducted at Khumaltar (mid-hill) and Parwanipur (terai)
to find out the performance of planting methods and weed management on yield and weed
dynamics and its succeeding effect on wheat and wheat weeds in rice wheat cropping
pattern. Design of the trial was split-plot replicated thrice with plot size of 2m x 3m
(Khumal) and 3m x Sm (Parwanipur). Varieties used were Khumal-4 (Khumal) and Radha-
11 (Parwanipur. The main plots comprises of 3 planting methods such as direct seeding of
on dry soil, direct seeding of sprout seeds in wet soil and transplanting while the sub-plot
consists of 5 weed management practices such as weedy check, weed free hand weeding two
pre-emergence application of butachlor @ 2 Uha, and pre-emergence of butachlor @ 1 Vha
+ one hand weeding. In Parwanipur there was a visual diffe-rences on weed dynamics in
different planting methods. Caesulitt ttxillares, Jsclwemum rugo.mm, Ecltilwcllloa sp. were
more in number in direct seeding rice while Fimhris(vlis littorttlis, Cyperus iria were more
in transplanting.
Plant height was not significantly different in both the locations showing that the varieties
could be planted in direct deeding method saving time. Tillers per method square in weed
management practices have also shown a significant difference in both the locations. But in
planting methods this was not significantly different in Khumal condition. From the result
two locations it could be summarized that significantly less gra~sy weeds (Khumal) and
broad leaf (Parwanipur) were recorded in transplanting method. In Parwanipur weeds like
Cyperus iritt, Fimbrisrylis littoralis were more in transplanting method while lsclwemum
rugosum, Ecllillocll/oa sp. Caesulitt ttxillaris were less but these weeds were more in direct
seeding method. In Khumal significantly higher number of grassy weeds were recorded in
direct seeding than in transplanting method. Regarding the grain yield, no significant
difference was recorded due different planting methods. It showed that the tested varieties
can be directly seeded which save the labor cost seed bed raising and transplanting. The rice
yield can be increased with an integrated weed management practice.
