Effect of different weed management practices on growth attributes of onion (Allium cepa L.)

Abstract

The field experiment was conducted during Rabi season of 2016-17 at the Horticulture Research cum Instructional farm, BTC CARS, Bilaspur (C.G.). The treatments consisted of ten combination of different agro input management practices viz., T1 (control weedy check),T2 (weed free),T3 (Pendimethalin @ 1.75 kg/ha (pre-emergence)),T4 (Oxyfluorfen @ 1 kg/ha (pre-emergence)), T5 (Quizalofop-ethyl @1 kg/ha (Post-emergence)), T6 (Pendimethalin @ 1.750 kg/ha (Pre emergence) + Quizalofop-ethyl @ 1 kg/ha (Post-emergence)), T7 (Oxyfluorfen @ 1 kg/ha (Pre-emergence) + Quizalofop-ethyl @ 1 kg/ha (Post-emergence)), T8 (Two hand weeding at 25 and 45 DAT), T9 (Black polythene mulch), T10 (Organic mulch with paddy straw @ 20 q/ha).The significantly maximum plant height (cm) was recorded 34.44 cm (T2), 65.89 cm (T2), 68.58 cm (T2), and 67.38 cm (T2) and minimum plant height (cm) was recorded 26.33 cm (T1), 50.80 cm (T1), 51.71 cm (T1), and 50.70 cm (T1) Was recorded 30, 60, 90 DAT and at harvest. The significantly maximum number of leaves was recorded 5.60 (T7), 8.30 (T2), 10.00 (T2), and 9.80 (T2) and minimum number of leaves was recorded 4.67 (T1), 5.47 (T1), 6.48 (T2), and 6.13 (T2) Was recorded 30, 60, 90 DAT and at harvest.
