Because of the difference in the physical and chemical composition between soil series, their effects on cotton yield and Et were dissimilar. The cotton yield and growth in soil series which have recolor and dry mulch on their surface were 29-49 per cent higher than those obtained in others. Cotton root growth varied according to the soil series and irrigation programmes. More than 50 per cent of root on dry basis was in the first 30cm soil layer and 25- 30 per cent of seasonal Et was also from the same soil depth. The effects of the different wetting depths on yield were statistically insignificant. Under deficit irrigation conditions, it was found that 30 per cent of the net irrigation water could be saved and by doing this, a 0.43 decar area would be opened to irrigation. For the highest yield, the irrigations must be applied when the available soil water in root depth is at 40-60 per cent level according to the soil series. Irrigation season lengths were compared in Herein plain in Southeastern Anatolia Project (GAP) area. It was determined that 80 or 90 days of season was best for optimum yield.

Measurements of yield and evapotranspiration (Et) were made under deficit irrigation conditions. In two locations, field studies were conducted for two years using two different soil textures, sowing dates and irrigation intervals. The amount of irrigation water was calculated using pan evaporation and pan coefficients which ranged from 0,40 to 1.00 increasing by 0,10 per treatment. Evapotranspiration was estimated by the water balance method. It was found that there was a strong linear relation between Et and yield. Peanut yield ranged from 170 kg/da to 667 kg/da depending on the treatments. Water production function, the relationship between relative decrease in yield, and relative Et, was also found. Yield response factors, ky, were higher in the light soil and the late sowing than in the heavy texture and early sowing. In addition it was demonstrated that the coefficients used to estimate Et and yield of peanut were not representative of the region's conditions.

(Location: IWMI-HQ Call no: 631.7 G000 RYD Record No: H07549)
The effects of trickle and other conventional irrigation methods on the yields of tomato, strawberry, citrus and banana, and water-use efficiency have been evaluated in this study. Experiments were conducted at various locations of different soil properties in ukurova. According to the results from experiments, it was defined that the highest from drip irrigation in old orange (25 years old) and lemon, however, there was no increase in yield from irrigation methods used in experiment. In commercial application, yield increased 27 per cent and the discarded yield decreased 5 per cent with drip irrigation as compared to other methods. Using the drip irrigation, 50 per cent of irrigation water was saved in banana; however, there was no increase in the yield from irrigation methods.

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.
