Correct Answer - Option 1 : Sprinkler irrigation
Sprinkler Irrigation: Water is applied through spray through a network of pipes and pumps. Used when the land gradient is steeper, irregular topography, and the soil is erodible.
Furrow Irrigation: Furrow is narrow field ditches that are excavated between rows of plants to carry water through it. In this method, only one-fifth to one-half of the land is cover through the water.
Border irrigation: Land is divided into a number of strips, separated by low levees called borders. Strip size: 10 – 20 m wide and 100 – 400m long. Water is made to flow from the supply ditch into each strip.
Sub-surface irrigation: It is the practice of applying water to soils directly under the surface. Moisture reaches the plant roots through capillary action.
