A field experiment was conducted at the Experimental Farm, Department of Horticulture, Assam Agricultural University, Jorhat during 2017-18 to study the weed management practices in a lawn of doob grass (Cynodon dactylon). The experiment was laid out in Randomized Block Design (RBD) with three replications. There were seven treatments viz. T1 (Control), T2 (Hand weeding at 15 days interval up to 90 days), T3 (Hand weeding at 30 days interval up to 90 days), T4 (Pendimethalin @ 1 kg ), T5 (Pendimethalin @ 1 kg followed by hand weeding at 45days, 60 days, 75 days after planting), T6 (Sulfosulfuron @ 25 g/ha) and T7 (Sulfosulfuron @ 25 g/ha followed by hand weeding at 45 days, 60 days, 75 days after planting). The weed control practices had significant effects on weed density, weed dry weight, growth characters as well as quality characters of a lawn. Pre-emergence application of pendimethalin @ 1kg followed by hand weeding at 45 days, 60 days, 75 days after planting recorded the lowest weed density and weed dry weight, while they were highest in case of T1 (Control). The growth of grass was satisfactory with the application of T5, so nutrient uptake from the soil was more. From the study, it could be inferred that application of T5 could minimize the weeds and thus it is suitable for establishment of a lawn. | Impact of different weed management practices on weed dynamics and growth parameters of Doob grass (Cynodon dactylon) in an Establishing Lawn
