Correct Answer: 1 and 3 only. ● Drip irrigation is a type of micro-irrigation that has the potential to save water and nutrients by allowing water to drip slowly to the roots of plants. ● Weeds, in order to grow, require water in fields. However, drip irrigation provides water mostly to plants and water is not spread on the field. This inhibits growth of weed. ● Flooding of fields lead to salinity. Drip irrigation may reduce soil salinity since it does not spread water on fields. ● Drip irrigation may reduce soil erosion since water is sprayed slowly to roots of plants. ● Hence all the three options are correct. However there is no option of 1,2 and 3. Hence, the next best answer is 1 and 3.
