    C Graded bunding Correct Answer Incorrect Answer
    D Hilly Farming Correct Answer Incorrect Answer
    E None of the above Correct Answer Incorrect Answer

    Solution

    Contour farming is one of the most commonly used agronomic measures for soil and water conservation in hilly agro-ecosystems and sloppy lands. All the agricultural operations viz. plowing, sowing, inter-culture, etc., are practiced along the contour line. The ridges and furrows formed across the slope build a continual series of small barriers to the flowing water which reduces the velocity of runoff and thus reduces soil erosion and nutrient loss.
