In India, about 6.74 M ha area is salt-affected, out of which saline and sodic soils account for approximately 2.95 and 3.79 M ha, respectively. About 5.5 M ha area also suffers from problem of waterlogging in the country. The management of saline soils often requires higher drainage intensity for quick leaching of salts from the soil profile; however, the existing drainage techniques involve heavy machinery and higher cost. Cut-soiler is a tractor-mounted, easy to use farm implement that constructs residue filled sub-surface drains. It uses surface scattered crop residue as filling material for preferential water flow to drain out excess water and salts from the operated area. This semi-controlled lysimeter study was conducted at ICAR-Central Soil Salinity Research Institute (CSSRI) in collaboration with 3) Japan International Research Center for Agricultural Sciences (JIRCAS) during 2019-2021. The simulated Cut-soiler drains were constructed in 12 lysimeters along with 12 control (without Cut-soiler) as main plots. The two soil types i.e. saline (light textured sandy loam) and non-saline (heavy textured silty clay loam) were laid as sub plot treatments and three irrigation water salinity (4, 8, 12 dS m-1) were applied in sub-sub plots in two replications. The Cut-soiler resulted in higher outflow of free water and salts with drainage during events of irrigation and rainfall. Hence, Cut-soiler reduced ~60% soil salinity after two years and improved mustard yield of successive crops. The Cut-soiler treatment significantly increased mustard seed yield by 31.5% over control. The Cut-soiler could be an effective technique for salinity, it can even be applied at individual farm level in a single operation. [ABSTRACT FROM AUTHOR] |
