Salah satu program penting dalam intensifikasi budidaya padi adalah pengelolaan air irigasi yang efisien. Pada subak di Bali pelaksanaan jadual tanam biasanya dilakukan secara serenpak sehingga terjadi puncak kebutuhan air yang tinggi. Akibatnya sangat berisiko terhadap kekurangan atau kelebihan air irigasai pada subak tersebut. Kondisi demikian menyebabkan efisiensi penggunaan air irigasi pada subak menjadi rendah. Salah satu solusi untuk meingkatkan efisiensi penggunaan air irigasi tersebut adalah dengan melakukan jadual tanam tidak serenpak yang pada subak dikenal dengan istilah nyorog. Dengan demikian perlu dikaji besarnya peningkatan efisiensi penggunaan air irigasi jika jadual tanam dilakukan secara nyorog Berdasarkan data yang telah dikompilasi diperoleh efisiensi penggunaan air irigasi yang dilakukan saat ini sebesar 76,52%. Saat ini pada obyek penelitian jadual tanam dibagi menjadi dua kelompok dengan beda jadual tanam antar kelompok tersebut sekitar satu bulan, dengan awal jadual tanam mulai Pebruari I.  Jika dilakukan jadual tanam secara serempak pada Pebruari II diperoleh efisiensi penggunaan air irigasi sebesar 69,05%.  Jika jadual tanam dilakukan secara nyorog dengan membagi subak menjadi empat kelompok dan setiap kelompok perbedaan jadual tanam sekitar setengah bulan serta awal jadual tanam pada Bulan Pebruari I maka diperoleh efisiensi penggunaan air irigasinya 86,52%.  Dengan demikian jadual tanam secara nyorog dapat meningkatkan efisiensi penggunaan air irigasi dari 69,05% menjadi 86,52%.    One important program in the intensification of rice cultivation is efficient irrigation water management. In subak in Bali the planting schedule is usually carried out simultaneously so that there is a high peak of water demand. As a result, it is very risky for irrigation water shortages or excess in the subak. Such conditions cause the efficiency of the use of irrigation water in subak to be low. One solution to improve the efficiency of the use of irrigation water is by not planting simultaneously which are known as nyorog in subak. Thus, it is necessary to assess the magnitude of the increase in the efficiency of the use of irrigation water if the planting schedule is carried out in a systematic manner. Based on the data that has been compiled in Subak Guama  the efficiency of the use of irrigation water is 76.52%. At present the object of the planting schedule is divided into two groups with different planting schedules between groups of about one month, with the start of the planting schedule starting in February I. If the planting schedule is simultaneously held in February II, the efficiency of irrigation water use is 69.05%. If the planting schedule is carried out systematically by dividing subak into four groups and each group different planting schedules of about half a month and the beginning of the planting schedule in February I, it is obtained that the water use efficiency of irrigation is 86.52%. Thus the planting schedule nyorog can increase the efficiency of irrigation water use through 69.05% to 86.52%.

A decrease in water resources, as well as changing environmental conditions, calls for efficient irrigation-water management in cotton-production systems. Cotton (Gossypium sp.) is an important cash crop in many countries, and it is used more than any other fiber in the world. With water shortages occurring more frequently nowadays, researchers have developed many approaches for irrigation-water management to optimize yield and water-use efficiency. This review covers different irrigation methods and their effects on cotton yield. The review first considers the cotton crop coefficient (Kc) and shows that the FAO-56 values are not appropriate for all regions, hence local Kc values need to be determined. Second, cotton water use and evapotranspiration are reviewed. Cotton is sensitive to limited water, especially during the flowering stage, and irrigation scheduling should match the crop evapotranspiration. Water use depends upon location, climatic conditions, and irrigation methods and regimes. Third, cotton water-use efficiency is reviewed, and it varies widely depending upon location, irrigation method, and cotton variety. Fourth, the effect of different irrigation methods on cotton yield and yield components is reviewed. Although yields and physiological measurements, such as photosynthetic rate, usually decrease with water stress for most crops, cotton has proven to be drought resistant and deficit irrigation can serve as an effective management practice. Fifth, the effect of plant density on cotton yield and yield components is reviewed. Yield is decreased at high and low plant populations, and an optimum population must be determined for each location. Finally, the timing of irrigation termination (IT) is reviewed. Early IT can conserve water but may not result in maximum yields, while late IT can induce yield losses due to increased damage from pests. Extra water applied with late IT may adversely affect the yield and its quality and eventually compromise the profitability of the cotton production system. The optimum time for IT needs to be determined for each geographic location. The review compiles water-management studies dealing with cotton production in different parts of the world, and it provides information for sustainable cotton production.

HighlightsAn integrated research and Extension program promoted adoption of computerized hole selection (CHS), surge irrigation, soil moisture monitoring, and multiple inlet rice irrigation (MIRI) for surface irrigators in Arkansas.Using a contest design, water use efficiency (WUE) was determined for maize, soybean, and rice fields, and report cards were provided to contest participants to provide feedback on their irrigation acumen.The highest yielding fields did not always result in the highest WUE.The contest was implemented on working commercial farms in the Arkansas Delta using flowmeters and in-field crop yield checks for the purpose of promoting adoption of irrigation water management (IWM).Abstract. The Arkansas “most crop per drop” irrigation contest is an integrated research and Extension program developed to assess water use, rainfall, and yield for the purpose of estimating water use efficiency (WUE). The irrigation contest resembles traditional yield contests, with the goal of documenting WUE and increasing adoption and awareness of irrigation water management (IWM) practices in the region. Adoption of IWM practices was greater for those who participated in the contest than their Arkansas peer average, with documented adoption increases of 33% for computerized hole selection, 28% for surge irrigation, and 51% for soil moisture monitoring. Keywords: Computerized hole selection, Soil moisture monitoring, Surge irrigation.

This study was conducted to investigate the effects of various irrigation water (W) and nitrogen (N) levels on growth, root-shoot morphology, yield, and irrigation water use efficiency of greenhouse tomatoes in spring–summer and fall–winter. The experiment consisted of three irrigation water levels (W: 100% of crop evapotranspiration (ETc), 80%, and 60% of full irrigation) and three N application levels (N: 100%, 75%, and 50% of the standard nitrogen concentration in Hoagland’s solution treatments equivalent to 15, 11.25, 7.5 mM). All the growth parameters of tomato significantly decreased (p < 0.05) with the decrease in the amount of irrigation and nitrogen application. Results depicted that a slight decrease in irrigation and an increase in N supply improved average root diameter, total root length, and root surface area, while the interaction was observed non-significant at average diameter of roots. Compared to the control, W80 N100 was statistically non-significant in photosynthesis and stomatal conductance. The W80 N100 resulted in a yield decrease of 2.90% and 8.75% but increased irrigation water use efficiency (IWUE) by 21.40% and 14.06%. Among interactions, the reduction in a single factor at W80 N100 and W100 N75 compensated the growth and yield. Hence, W80 N100 was found to be optimal regarding yield and IWUE, with 80% of irrigation water and 15 mM of N fertilization for soilless tomato production in greenhouses.

The article contains data obtained from evaluations related to irrigation water use efficiency (IWUE) and water use efficiency (WUE), for the main crops, irrigated at different stages of growth, on the basis of some findings obtained in the Research Institute in Kırklareli. Each of the experimental crops was sown and farmed following procedures applied by the farmers in the region, except of the irrigation applications which were based on the sensitivity of a certain crop to water shortage in the soil, during the specific growth stages. Similar procedures were applied and all the experimental treatments were irrigated at growth stages, as predicted in the research methodology, and water amounts required to fill the 0-90 cm soil depth to field capacity were implied. Evaluation data obtained from the field experiments with three major crops, grown on the non-coastal lands of Thrace Region showed, that the productivity of irrigation water, as well as water use efficiencies of all analysed crops, are growth stage controlled. The highest IWUE and WUE efficiencies of 0.87 and 0.92 kg da-1 m-3; and 1.08 kg da-1 m-3 and 0.81 kg da-1 m-3; were determined for wheat and sunflower crops, irrigated at booting and flowering stages, respectively. Each m3 of irrigation water, applied during the most sensitive fruit formation stage (Ff) of pumpkin crop, provided additionally 8.47 kg da-1 fruit yield, 8.09 fruit numbers and 0.28 kg da-1 seed yields, more than those of rainfed farming (R).
