Shilpa Koushik, BL Chandrakar and Amit Kumar Shukla
The present investigation was conducted at Instructional Farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) India during the kharif season (June-October) 2006. The experiment was laid out in randomized block design comprised of eight treatments of various combinations of different herbicides viz. T1: PIH 2023 10% SC 15 g a.i/ha at 18 DAS; T2 : PIH 2023 10% SC 20 g a.i/ha at 18 DAS; T3: PIH 2023 10% SC 25 g a.i/ha at 18 DAS; T4 : PIH 2023 10% SC 30 g a.i/ha at 18 DAS; T5 : PIH 202310% SC 60 g a.i/ha at 18 DAS T6 : Almix 20% WP 4 g a.i/ha 18 DAS; T7 :Control (unweeded check) and T8 : Hand weeding at 30 DAS with three replications. Rice cultivar “IR-64” was grown as a test crop. Rice was manually sown with a seed rate of 60 kg ha-1 on 25th July, 2006 and harvested on 15th and 16th November, 2006. The crop was fertilized with 100:60: 40 kg NPK ha-1, respectively. Results revealed that almost all growth parameters, yield attributes and grain yield were maximum grain yield was produced under of PIH 2023 10% SC @ 60 g a.i ha-1 over rest of the treatments. Echinochloa colona, Cyperus spp., F. miliaceae, L. hyssopifolia were the pre-dominant weeds in experimental plot. Minimum weed density was noted under post emergence application of Almix 4 g ha-1 and PIH 2023 25 g ha-1 at 20, 40, 70 and 90 DAS. Whereas, at harvest lower dry matter of weeds and highest weed control efficiency was recorded under Almix 4 g ha-1 (T6), PIH 2023 25 g ha-1 and PIH 2023 60 g ha-1, respectively. It was found effective to control broad spectrum of weeds viz., grasses, sedges and forbs.
