Question
Following are the statements with respect to
economization of irrigation water in rice A. Rice should be cultivated on heavy soils with percolation above 5 mm per day B. Subsoil loosening to enhance water flux to soil. C. Rice should be grown in small isolated blocks to reduce seepage D. Application of tank silts to light soils E. Pudding to reduce soil permeability Choose the correct answer from the options given belowSolution
Subsoil loosening can improve water movement and infiltration in the soil profile, allowing water to reach deeper layers and reducing surface runoff. Pudding to reduce soil permeability
