 ABSTRACT

The present study entitled Impact of Stale Seedbed and Herbicides on Crop Growth, Yield Attributes and Weed Indices in Transplanted Rice was carried out during the Late samba season (September 2022 - February 2023) at Annamalai University Experimental Farm, Chidambaram, Tamil Nadu, India. The nine treatments comprised different weed management practices viz., Unweeded control (T1), weed-free check (T2), Stale seed bed technique (SSBT) alone (T3), SSBT followed by one hand weeding at 25 DAT (T4), SSBT followed by Pretilachlor 6.0 % + pyrazosulfuron ethyl 0.15 % GR @ 660 g ha-1 at 3 DAT (T5), SSBT followed by Triafamone 20 % + ethoxysulfuron 10 % WG @ 220 g ha-1 at 8 DAT (T6), SSBT Followed by 2,4-D sodium salt @ 1560 g ha-1 at 35 DAT (T7), Pretilachlor 6.0 % + pyrazosulfuron ethyl 0.15 % GR @ 660 g ha-1 followed by hand weeding at 35 DAT (T8), Pretilachlor 6.0 % + pyrazosulfuron ethyl 0.15 % GR @ 660 g ha-1 Followed by 2,4-D sodium salt @ 1560 g ha-1 at 35 DAT (T9). The results revealed that the treatment SSBT followed by One Hand Weeding at 25 DAT (T4) which was statistically on par with SSBT followed by Triafamone 20 % + ethoxysulfuron 10 % WG @ 220 g ha-1 at 8 DAT (T6) recorded the lower weed biometrics, lower weed index, higher crop growth, yield and weed indices in transplanted rice.

Keywords: SSBT, Triafamone, ethoxysulfuron, Hand weeding, weed biometrics, Weed indices, Crop growth and yield.
