Water is very important to the input sector in agriculture as it is responsible for the growth and development of plants as plants perform the various biological and physiological and chemical activity for the development and life process with help of water and the nutrients from soil when irrigation is done the plant absorb the nutrient from the soil. Water act as transfer agent for the transport of nutrient to the plant. In Agriculture water is as important as water required for survival of human being.
What is agricultural water used for?
Agricultural water is used for irrigation, pesticides, fertilizers and frost control. Because plants are about 80 or 90% water and animals and humans needs plants in order to live. No water means no plants and no plants means no animals or humans. Where there is no water, there are no plants.
Why does irrigation water evaporate?
When crops are irrigated, the irrigation water contains small amount of dissolved minerals and salt. Without drainage, the water evaporates from the soil, leaving the salt behind. When salt cncentrations become high enough, the salts damage plant roots. This process is a kind of chemical burn.

Why is water important to life?
As a solvent, it also serves as a transport medium for mineral nutrients from the soil, as well as in the translocation of organic substances within the plant. It is a chemical reactant in photosynthesis hen ce vital to life. It is a product of respiration. It is also believed responsible, or at least contributing, to the cooling of plants through the process of transpiration. In addition, it serves as a growth medium in hydroponics, the culture of plants in soilless nutrient solutions.
Why do plants get leggy?
Excess water within the plant can also cause injury. Edmond, et al. (1978) explained that under conditions that favor high absorption and low transpiration rates , there is a build-up of high turgor pressure in the region of cell elongation which causes maximum swelling of the cells. This results in the development of leggy seedlings. Likewise, under similar conditions, growth cracks occur as exemplified by bursting heads of cabbage and cracked fruits of tomato and roots of carrot and sweet potato.
Is water a solid or a liquid?
As a liquid, it is clear, colorless, and odorless. In such a state of matter, it has been described as a fluid, a substance that flows freely without a fixed shape. It melts and freezes at 0°C (32°F) and boils at 100°C (212°F) under normal atmospheric pressure.

Does water affect plants?
As with other climatic factors, water can possibly cause unfavorable effects on plant growth and development . Excess water in the soil can injure flood-prone plants, like corn (maize), due to lack of oxygen. In this case, water stress due to flooding means oxygen stress by deficiency (hypoxia) or total absence (anoxia).
Do plants need water?
But plant responses differ and the importance of water likewise differs depending on plant species. Most plants are mesophytes, that is, they are adapted to conditions with a moderate supply of water. But some, called hydrophytes, require watery or water-logged habitats while others, called xerophytes, are more tolerant to dry conditions. The resurrection plants are in fact capable of surviving near complete desiccation. They are capable of losing 90% or more of cellular water in their vegetative tissues and still remain alive. They can remain dry and appear somewhat dead for several years but, when rehydrated, they suddenly spring back to life (Le and McQueen-Mason 2006).
