Influence of Planting Methods, Intercrop and Integrated Weed Management Practices on Yield of Turmeric (Curcuma domestica Val.)

A field experiment was conducted during 2013-14 and 2014-15 to study the effect of planting methods, intercropping and integrated weed management practices on yield of turmeric. Two planting methods of turmeric viz., paired row of 80/20 cm and paired row 70/30 cm; two intercrops viz., baby corn and greengram and three weed management practices viz., non-chemical i.e. mulching followed by four hand weeding at 35, 65, 95 and 140 days after planting (DAP), pre-emergence application of metribuzin @ 500 g ha-1 followed by five hand weeding at 35, 65, 95, 140 and 185 DAP and pre-emergence application of oxadiargyl @ 90 g ha-1 followed by five hand weeding at 35, 65, 95, 140 and 185 DAP along with one weedy check (control) were evaluated. Turmeric planting in paired row 70/30 cm and intercropping greengram in between paired rows with non-chemical weed management practice by mulching followed by four hand weeding at 35, 65, 95 and 140 DAP (M2I2W2) proved superior in most of the attributes studied, followed by paired row 70/30 cm and intercropping baby corn with non-chemical weed management practice by mulching followed by four hand weeding at 35, 65, 95 and 140 DAP (M2I1W2).
