Question 10

Consider the following statements in connection with soil-water-crop relationship:
1) Water utilization by plants is mainly from capillary water.
2) The amount of irrigation water required to meet the evapotranspiration needs of the crop during its full growth duration is its consumptive irrigation requirement.
3) The depth of water required to bring the soil-moisture level of a given soil up to its field capacity is called hygroscopic water.
4) With continuous increase in quantity of water applied, the yield of most crops increases up to a certain limit and then is expected to be constant.
Which of the above statements are correct?
