There are some plants that need to be watered regularly if they are to survive and grow. If you go on a vacation for even a few days and do not make arrangements to water them, they will wither away and dry. There are other plants whose roots get damaged if you water them too often. These plants usually grow well in dry climates .

Irrigation
Saturday, May 31st, 2008Water is needed by all living things – both plants and animals. In many areas, when natural resources for supply of water are inadequate, irrigation is needed. Irrigation helps in large areas from limited water sources to attain maximum benefits especially in dry areas and where the rainfall is very less.
It also saves time.
There are different forms of irrigation used like drip irrigation, sprinkler irrigation, surface irrigation, depending on the crop and the amount of water available.
a. In drip irrigation water is allowed to pass to the roots of the plants drop by drop
b. in sprinkler irrigation water is allowed to pass to one or more locations and the water is sprinkled to the plants all round it.
c. In surface irrigation the water is allowed to pass through channels where there is slope gradient.
Agronomy vs Agriculture
Wednesday, April 16th, 2008Agronomy is limited to crop and soil science while agriculture is a more comprehensive field and covers all farming related activities. Agriculture covers crop science, soil science, animal husbandry, horticulture, floraculture, silviculture, aquaculture, sericulture and other fields as well as related activities like design and maintenance equipment used for agriculture.
One of the basic differences is that agronomy is related to plants and is usually focussed on food and cash crops like rice, wheat, corn, tobacco and methods to increase the crop output per acre. Agriculture also includes other farming related activities related to animals like rearing of cattle, goat, sheep, fish, chicken , fish and prawns. The cultivation of fruits and vegetables as well as different varieties of flowers is also not included in agronomy.
