Water use in the country depends very much on it’s efficiency in water use. Even in most technologically
advanced country, the efficiency of irrigation is only thirty percent. As the people of California, in the United
States of America, and Israel use water ethically and with enormous care the efficiency in use is high. They are also
good in water management activities. For example drip irrigation has been used in Israel as well as California to
best effect. The formers and horticulturists make the water drip drop by drop at the roots of the crop plants. This
system of irrigation has now come into use in India. With this method of irrigation a high output of crops is being
harvested with small amount of water. In this way salivation of the lands is also averted to a great extent.

Answer:
a) Why is the efficiency in water use high in some countries?
answer:The efficiency of irrigation is only thirty percent. As the people of California, in the United States of America, and Israel use water ethically and with enormous care the efficiency in use is high. They are alsogood in water management activities.

All in all, further developing water use effectiveness implies expanding water "efficiency".)
b) Explain drip irrigation.
answer:The formers and horticulturists make the water drip drop by drop at the roots of the crop plants. This system of irrigation has now come into use in India.
explanation:(Drip irrigation is once in a while called trickle irrigation and includes trickling water onto the dirt at exceptionally low rates (2-20 liters/hour) from an arrangement of little breadth plastic lines fitted with outlets called producers or drippers. Water is applied near plants with the goal that main piece of the dirt in which the roots develop is wetted (Figure 60), dissimilar to surface and sprinkler water system, which includes wetting the entire soil profile. With trickle water system water, applications are more continuous (typically every 1-3 days) than with different strategies and this gives a truly good high dampness level in the dirt in which plants can thrive.)
c) What is the result of the use of drip irrigation?
answer:With this method of irrigation a high output of crops is being harvested with small amount of water. In this way salivation of the lands is also averted to a great extent.
explanation:(The producers gradually trickle water into the dirt at the root zone. Since dampness levels are kept at an ideal reach, plant efficiency and quality move along. Also, dribble water system: Prevents infection by limiting water contact with the leaves, stems, and product of plants)
