Irrigation is the artificial application of water to the land or soil. It is used to assist in the growing of agricultural crops, maintenance of landscapes, and revegetation of disturbed soils in dry areas and during periods of inadequate rainfall. Additionally, irrigation also has a few other uses in crop production, which include protecting plants against frost, suppressing weed growth in grain fields and preventing soil consolidation. In contrast, agriculture that relies only on direct rainfall is referred to as rain-fed or dryland farming.
Irrigation systems are also used for dust suppression, disposal of sewage, and in mining. Irrigation is often studied together with drainage, which is the natural or artificial removal of surface and sub-surface water from a given area.
Irrigation has been a central feature of agriculture for over 5,000 years and is the product of many cultures. Historically, it was the basis for economies and societies across the globe, from Asia to the Southwestern United States.
Irrigation in viticulture is the process of applying extra water in the cultivation of grapevines. It is considered both controversial and essential to wine production. In the physiology of the grapevine, the amount of available water affects photosynthesis and hence growth, as well as the development of grape berries. While climate and humidity play important roles, a typical grape vine needs 25-35 inches (635-890 millimeters) of water a year, occurring during the spring and summer months of the growing season, to avoid stress. A vine that does not receive the necessary amount of water will have its growth altered in a number of ways; some effects of water stress (particularly, smaller berry size and somewhat higher sugar content) are considered desirable by wine grape growers.
In many Old World wine regions, natural rainfall is considered the only source for water that will still allow the vineyard to maintain its terroir characteristics. The practice of irrigation is viewed by some critics as unduly manipulative with the potential for detrimental wine quality due to high yields that can be artificially increased with irrigation. It has been historically banned by the European Union's wine laws, though in recent years individual countries (such as Spain) have been loosening their regulations and France's wine governing body, the Institut National des Appellations d'Origine (INAO), has also been reviewing the issue.

A budget is a quantitative expression of a plan for a defined period of time. It may include planned sales volumes and revenues, resource quantities, costs and expenses, assets, liabilities and cash flows. It expresses strategic plans of business units, organizations, activities or events in measurable terms. International Budget Partnership regularly monitors global budget information for the civil society.
A budget (derived from old French word bougette, purse) is a quantified financial plan for a forthcoming accounting period.
A budget is an important concept in microeconomics, which uses a budget line to illustrate the trade-offs between two or more goods. In other terms, a budget is an organizational plan stated in monetary terms.
Budget helps to aid the planning of actual operations by forcing managers to consider how the conditions might change and what steps should be taken now and by encouraging managers to consider problems before they arise. It also helps co-ordinate the activities of the organization by compelling managers to examine relationships between their own operation and those of other departments. Other essentials of budget include:
Budget Rent a Car System, Inc. is an American car rental company that was founded in 1958 in Los Angeles, California by Morris Mirkin. Budget's operations are headquartered in Parsippany-Troy Hills, New Jersey.
With its original fleet of 10 cars, the company lived up to the 'Budget' name by undercutting the daily and per mile rental rates of the established airport based car rental companies. Mirkin was joined in 1959 by Julius Lederer (husband of columnist Ann Landers) who built the company, and made it an international company. In 1960, the headquarters moved to Chicago, Illinois and the rental fleet expanded with franchised and wholly owned rental outlets.
The company was eventually acquired by Transamerica Corporation, and then sold in 1986 in a leveraged buyout by Gibbons, Green and van Amerongen Ltd., along with management (led by CEO Clifton E. Haley) and selected investors. The company made its first public stock offering in 1987.
Team Rental Group purchased the public company in 1997 and took the name Budget Group. In 2002, it sold the company's assets to Cendant Corporation, which also owned Avis and in September 2006, Cendant Corporation separated into four independent companies. The real estate division became Realogy, Inc., its hospitality services division became Wyndham Worldwide, and the travel distribution services division became Travelport, Inc., an affiliate of The Blackstone Group. In 2006, following the Travelport sale, Cendant, now composed solely of its vehicle rental services businesses, renamed itself Avis Budget Group.
