Abstract: In-situ conservation of resources in ginger is much influenced by alteration in surface topography and placement of mulches. Ginger (Zingibar officinale Roscoe.) is long duration crop and sensitive to excess water and prolonged dry spells, therefore experiment was conducted during 2011-12 and 2012-13 at ICAR Research Complex for NEH Region, Arunachal Pradesh, India to know the effect of alteration in land topography and mulching on water, crop and energy productivity. Surface land topography alterations viz. broad bed furrow (BBF), ridges and furrow (R&F) and flatbed (FB) and mulches with Imperata cylendrica (IC), pine needle (PN); double mulching of paddy straw followed by weed biomass (PS) and bare land (BL) were assessed on ginger. Results revealed that both the years the runoff in BBF was reduced by 23.5%, and contributed 50.3-56.5% lower soil moisture over FB plots. Among the placed mulches, the runoff was lowered in PN by 30.3-32.0% over BL, whereas, water use efficiency was 26.5-26.7 kg/ha/mm with PS and lowest with BL plots. The rhizome yields were improved with BBF (39.3-47.3%) and PS (35.8-42.2%) than FB and BL, respectively. BBF altered plots recorded 24.6-32.1% higher harvest monetary benefit (HMB), with better energy indices, similarly, the application of PS was observed with the highest energy values. Therefore, alteration in land topography and the use of available crop residues and tree leaf litter as mulch are promising resource conserving sustainable production technologies.
