Title: Micro-irrigation de la tomate sous serre
Keywords: tomato
water requirement
Issue Date: 30-Dec-2013
Abstract: The agriculture in green house is one of the intensive production models, so factors of production must be maximized in order to warrant net profit. The present work consists on an example of optimal design set up of the micro-irrigation network of cultivated greenhouses of tomato. Obtained results by using a theoretical model of design showed that 157.5 litres per plantation are necessary for the irrigation during 78 h 42. One greenhouse requires 157.5 m3 and a hectare 4 000 m3. The water capacity of the network head for one hectare is 27 m3/h, if we irrigated an hectare in two times, it require 54 m3/h and 2 bars of a global pressure for the total area. From the previews observations, the equipment economic aspect of the project suggest that an amount of 13,9 millions DA per hectare and the relative expense per year is evaluated of 50 % of the global cost.
