Investigations on water use in carnations irrigated by mini-dripping and dripping at reduced rates
1993
Mor, E.
A field trial was conducted on carnations to determine the contributions to water use of mini-dripping through pulsators. This was done in winter 1991/92 under unusually severe winter conditions. We did not find this new technology to offer any advantages compared to conventional drip irrigation as far as water economy was concerned, nor was the horizontal distribution of water improved. However, concentrations of salts in the top 20 cm of soil, was lowered by mini-dripping compared with irrigation by conventional dripping. The moisture content in soil under mini-irrigation was low during the entire growing period. This finding points to a possible advantage of mini-dripping in irrigation with saline water. The moisture conditions of soil irrigated by mini-dripping markedly boosted development of moss on the soil surface, and this indicates the moisture level in the upper soil layer. These effects of mini-dripping are further studied in the 1992/93 season.
