Q1. Which of the following is/are the advantage/ advantages of practicing drip irrigation? 1. Reduction in weed 2. Reduction in soil salinity 3. Reduction in-soil erosion Select the correct answer using the code given below.
Explanation
Drip irrigation is a type of micro-irrigation system that applies small amounts of water and fertilizer uniformly across a specific area. Examples of drip irrigation methods include surface drip irrigation, subsurface drip irrigation (SDI), drip tape, and micro-sprinklers.
Option 1 is correct: Drip irrigation delivers water directly to the plant’s root zone, reducing water availability for weeds, which helps in minimizing weed growth.
Option 2 is incorrect: Some of the disadvantages of Drip Irrigation are sensitivity to clogging, problem of moisture distribution, salinity hazards and high cost compared to furrow.
Option 3 is correct: Drip irrigation generally doesn’t contribute to significant erosion since water is delivered at low pressures and in controlled amounts, unlike surface irrigation where water flow can lead to erosion.
