| dc.description.abstract | The experiment was conducted at KRCCH, Arabhavi in 2017-18 to study the effect of different weed management methods on growth, yield and quality of transplanted turmeric (Cv. Sale m). The experiment was laid out with 13 treatments (hand weeding at 15 days interval upto 3 months, Pre-emergent application of Alachlor 50% EC @ 1 and 1.5 kg a.i ha-1, Atrazine 50% WP @ 1 and 1.5 kg a.i ha-1, Metribuzin 70% WP @ 0.7 and 1.05 kg a.i ha-1, Oxyfluorfen 23.5% EC @ 0.2 and 0.3 kg a.i ha-1 and Pendimethalin 30% EC @ 1 and 1.5 kg a.i ha-1, 30 μ silver black polythene mulch and unweeded control) according to randomized block design and replicated thrice. The weed density and dry weights were lowest in polythene mulching (3.33 m-2 and 2.67 g m-2, respectively) at 30 DAT, while, the highest was found in unweeded control (35.33 m-2 and 62 g m-2, respectively). Among the herbicides, application of Metribuzin 70% WP @ 1.05 kg a.i. ha-1 recorded significantly lower weed biomass (8.00 m-2 and 9.33 g m-2, respectively). The polythene mulching recorded highest values for growth attributes like average plant height (52.40 cm), plant spread (32.27 cm), number of tillers per plant (2.20), number of leaves (8.40), length of recently matured leaf (34.00 cm) and its area (233.67 cm2) at 180 DAT and resulted in the highest yield (11.67 t ha-1), net returns (` 1,21,019) and benefit: cost ratio (2.10). While, the same parameters were the lowest in unweeded control (38.53cm, 26.03cm, 1.13, 6.33, 22.4 cm, 110.7 cm2, 2.10 t ha-1, ` 57,963 and 0.42, respectively). Among the herbicides, application of Oxyflourfen 23.5% EC @ 0.3 kg a.i. ha-1 recorded higher values (50.93 cm, 31.90 cm, 1.80, 8.13, 33.00 cm, 222.86 cm2, 7.44 t ha-1, ` 45,489 and 1.43, respectively). Whereas, Metribuzin 70% WP @ 1.05 kg a.i. ha-1 recorded lower values for these parameters (41.07 cm, 26.23 cm, 1.27, 6.40, 20.33 cm, 116.82 cm2, 2.36 t ha-1, ` 55,987 and 0.46, respectively) and found to be toxic to the transplanted turmeric. | en_US |
