ABSTRACT
Automated computerized irrigation is a relatively new concept that emerged recently from the increased demand for better irrigation. The need for higher production in agriculture and the restrictions on availability of water quantities are the main reasons behind the need for better controlled and automatic irrigation. Studies of plant growth have shown that optimal yields are not necessarily a result of greater water quantities but of proper application scheduling (correct intervals and quantities). With the sophisticated irrigation systems and the associated accessories (fertilizer injectors, filters, pressure valves, etc.), control and automation is a required procedure for proper operation and management.
