Alteration in micro-topography and mulching are important agronomic practices to conserve the resources in situ. Turmeric is sensitive to weed infestation and soil loss. Studies were conducted during 2011–12 and 2012–13 in a silt loam soil to evaluate the weed suppression, nutrient leaching, water use and yield of turmeric under varying land configurations [broad bed and furrow (BBF), ridge and furrow (RF), and flat bed (FB)] and mulch materials [paddy straw followed by weed biomass (PS), thatch grass (Imperata cylendrica; IC), pine needle (PN) and no mulch (NM)]. Results revealed reduced weed density, dry biomass and superior weed suppression with BBF and either of mulch. Weed suppression followed the trend from higher to lower with PN > IC > PS > NM. The soil and nutrient (nitrogen, phosphorus and potassium) losses under BBF and PN mulch were the lowest, indicating better conservation of the soils. Besides, the rhizome yield, water use efficiency, economic and energy parameters were improved by following higher to lower with BBF > RF > FB and PN > IC > PS > NM. Land configuration and mulch suppress the weed growth, reduce the soil and nutrient losses, leading to higher rhizome yield, enhanced water use, superior economics and improves energy values.

维修在微地形和覆盖是很重要的农艺措施，以节省资源原位。姜黄对杂草侵染和土壤流失很敏感。在2011–12和2012–13年期间，在淤泥壤土中进行了研究，以评估不同土地结构[宽床和犁沟（BBF），垄沟和犁沟（RF）]下的杂草抑制，养分淋失，水分利用和姜黄的产量。 ，平板床（FB）]和覆盖材料[稻草，杂草生物量（PS），茅草（Imperata cylendrica）; IC），松针（PN）和无覆盖物（NM）]。结果显示，BBF和两种覆盖均可降低杂草密度，减少干生物量并抑制杂草。PN> IC> PS> NM时，杂草抑制遵循从高到低的趋势。BBF和PN覆盖下土壤和养分（氮，磷和钾）的损失最低，表明对土壤的保护更好。此外，随着BBF> RF> FB和PN> IC> PS> NM，根茎产量，水分利用效率，经济和能源参数通过从高到低依次提高。土地配置和覆盖可以抑制杂草的生长，减少土壤和养分的流失，从而使根茎产量更高，用水量增加，经济效益更高，能源价值更高。
