In recent years, there has been a rapid expansion of greenhouse grown crops in the Mediterranean region of Turkey. Additionally, new irrigation techniques have also been introduced in greenhouses. The latest irrigation technology introduced in greenhouses is drip or trickle irrigation. Additionally, tensiometers have also been introduced and now widely used for irrigation timing in vegetables. Although tensiometers are not suitable for direct measurement of soil water content, they measure matrix pressure (i.e., energy status of soil water) and therefore, they are most reliable for irrigation timing, particularly in vegetables. Irrigation scheduling of conventional soil-grown greenhouse crops depends on evapotranspiration (ET) rates and readily available soil water content (about 50% of total available water within the top 30 cm soil, most active root zone under localized irrigation systems). The tensiometer readings in the range of 0-75 cb is adequate for drip irrigated crops and in most soils under greenhouse production, as non-stress conditions are usually required for high yields. Results of some case studies of drip irrigation under greenhouse conditions are discussed.
