`A technique of growing plants in nutrient solution”. Hydroponics literally means water-working or water-activation. It is a cultivation technique for growing plants in highly oxygenated, nutrient enriched water, rather than soil. The nutrient solution and its management are the cornerstone for a successful hydroponics system. The function of a hydroponics nutrient solution is to supply the plant roots with water, oxygen and essential mineral elements in soluble form. In soil, biological decomposition breaks down...

The crop surface is continuously growing. Spain and Italy are the main producers worldwide, followed by Greece, Turkey and...
It is a fruit tree of great importance worldwide, coming from china and from the rosaceous family. The countries of bigger production of peach are the United States, Spain, Italy and Greece. Spain, from the European point of view is the third producer with 900.000 tons and 78.000 hectares. Most of the production (around the 70%) is intended for the fresh consume and the rest to the industry. The main producer areas in Spain are: Valle del Ebro, Lérida y Murcia.
It is a pyramidal-shape tree, of the rosaceous family, coming from oriental Europe and Occidental Asia. The bigger producers are China, Italy, United States and Argentina (source: FAO). The multiplication is done by seed and grafting. The pear, with difference to most of the fruits coming from deciduous trees, have better quality when they are harvested slightly green.
The maize is a crop of the gamine family coming from Centro America and with thousand of years old. The approximate world production is of 790 millions of tons of grain in 158 millions of hectares. The main producers are United States, China, Brazil, having nearly the 62% of the total world production.
Alfalfa is a crop of the legume family and its scientific name is Medicago sativa. Alfalfa is a perennial plant of erect growth and is one of the most extended forage crops within temperate climate countries.
Cucumbers come from the tropical areas of South-Asia and they grow in greenhouses in different climates. They are smooth and the colour, depending on the variety, can change from light green to dark green, reaching a yellowish colour when it is completely mature. They produce good outputs in warm and cold climates. Under extreme conditions ventilation and heating systems are necessary. The bigger producers are China, Turkey, Iran, United States, Japan and Russia.
Tea plant is a shrub that develops in tropical or subtropical climates, coming from continental China, India, Sri Lanka, Taiwan, Japan, Nepal, Austria and Kenya. Tea trees are cultivated in gardens, huge forests of small trees. The bigger producers worldwide are China and India; both produce the 50% of the total. The tea production is very competitive all around the world. Not technified irrigation systems, obsolete and the lack of water are the most important factors that reduce the tea production.

The organization model of irrigation at the same level of the basin is considered one of the best ways to use efficiently the available water and the management of this resource. One of the most successful examples of this kind of Management is the Watering Communities. These communities are consortium of farmers in charge of the organization of the use of public, surface and subsurface water.
It is an irrigation system that uses a main network to distribute the filtered and pressurized water to the emitting pipes under the surface of the terrain and together the crop line. The emitters in line supply a unique flow rate by each emitting point that is among the interval of 0,6-8l/h. The volume of water supplied under the surface of the soil (nearest the plants) generates a spatial distribution of the same named “dump bulb”. The shape and size of this “dump bulb” is different from the surface localized...
Grapevine is a deciduous bush belonging to Vitaceas family. Its scientific name is Vitis vinífera. Its economic importance is due to its fruit, the grape, used so much for direct consumption as fermented to produce wine.
