Aim: The storage of clean water assets around the world has produced a requirement for their ideal use. Innovative irrigation is the advance method which can overcome the drawbacks of traditional drip irrigation. Materials: In this proposed system two soils, sandy soil with average moisture content 60% and clay soil with average moisture content 76% are taken; A total of 20 samples are taken from 2 groups. The sample size was estimated to be 5 in each group using Gpower with the input soil samples with alpha error of 0.95, threshold value of 0.05, confidence level of 95%, pretest G- power is 80%. Significance of this proposed system is 0.05. Result: Comparing the two soils, the soil which can maintain a low percentage of moisture content appears to be suitable for the irrigation. Minimum percentage of moisture can be achieved by using the smart irrigation system which appear to be better than the traditional drip irrigation. The moisture content in sandy soil is 83% and the clay soil is 63%. Since moisture content is inversely proportional to water content. Conclusion: Clay soil appears to be better than sandy soil, traditional issues in drip irrigation is overcomed by innovative irrigation system.

A computer-controlled drip irrigation system was used to implement three types of moisture regimes in the potting medium of container-grown chrysanthemum [Dendranthema × grandiflorum (Ramat.) Kitamura] plants: “constant” moisture tension treatments were maintained by setting low- and high-tension set-points to the same value; “variable” tension treatments were imposed by setting the low- and high-tension set-points to 2 and 7 kPa, respectively, “timed” irrigation consisted of irrigating once per day for a fixed (excessive) duration that resulted in fluctuations in tension ranging from O to 10 kPa. Constant moisture tension conditions in the range of 0.8 to 16 kPa showed decreasing fresh and dry weight patterns with increasing tension, decreasing average moisture content, decreasing amounts of applied irrigation solution, and, consequently, with decreasing amounts of nutrients applied. Plants grown under conditions where the moisture content fluctuated appreciably (variable and timed) tended to be larger than those grown within the narrow tension ranges (constant); for the latter, optimal plant growth occurred at the lowest tension (0.8 kpa) and highest average moisture content (71%). For fluctuating conditions, the control (with the widest fluctuations) had the highest dry weight growth. The variable tension treatments, while resulting in average moisture tensions of 4.4 to 4.9 kpa, resulted in plant growth similar to plants grown at constant low tension (0.8 to 1.6 kPa), rather than those grown at tensions between 4 and 5 kPa.

An experiment was conducted in the field of the University of Baghdad in 2015 In loamy sand  soil to study the effect drawbar and field efficiency using of a combine implement used for installation subsurface irrigation pipes and drip irrigation under different discharges. Subsurface irrigation system and drip irrigation system with three levels of discharge included 2.5,3.0 and3.5 L\hr-1 were used in this experiment. Field efficiency, drawbar, soil moisture content and soil  bulk density were measured in this stdy. Nasted design under randomized complete block design(CRBD) with three replications were used in this experiment. Least significant differences (L.S.D) at 0.05 levels were used to compare the mean of treatments. The results were showed the follows: Subsurface irrigation got 12.7 kw drawbar and 29.45% moisture content and 1.43g/cm3 bulk density g/cm3 and  84% field efficiency.While Drip irrigation system got 9.73kw drawbar and 25.19% moisture content and 1.47g/cm3 bulk density and 89% field efficiency. The successful of using combine implement to install subsurface irrigation pipes with tillage at the same time.

A study was carried out on the root distribution of mature olive trees (olea europaea, L., var. manzanillo) grown on a sandy soil, irrigated by means of drip irrigation, and on the nutrient distribution in the soil and plants. Soil was sampled at a distance of 20-160 cm from the tree trunks at depths of 0-80 cm. Leaves were also analysed for nutrient content. The roots were concentrated in the area 80-140 cm from the trunk at a soil depth of 20-60 cm, i.e. in the zone with the highest soil water content. In the horizontal layer, magnesium, iron, manganese, zinc and copper mostly decreased at the ends of the wet area, while in the vertical layer, the 0-20 cm surface soil layer was the richest in potassium, calcium, manganese, zinc and copper. Phosphorus concentrations fluctuated. The average values of potassium, magnesium, iron, manganese, zinc and copper concentrations in olive leaves were significantly higher in bearing years than in non-bearing ones. For this reason it is important to increase the doses of fertilizers containing these elements after bearing years to replace the high removal.

<p class="teksabst"><strong>Abstract.</strong><em> </em>Sugarcane (<em>Saccharum officinarum</em> L.) growth and production are greatly affected by water availability. The lack of water availability in sugarcane cultivation can be surmounted by irrigation. In performing irrigation, it is essential to understand the sugarcane crop water requirement and soil texture as they influence the irrigation efficiency. To date, drip irrigation is considered as the most efficient type of irrigation. This study aimed to investigate both agronomic performance and economic benefits of different irrigation methods for sugarcane grown in sandy (in Kediri) and clay (in Pasuruan) soils. The irrigation treatments were surface drip irrigation, sub-surface drip irrigation, and conventional irrigation, while the conventional irrigation through drains was the control treatment. The experimental design was a Randomized Complete Block Design with three replications. In sandy soil, both surface and sub-surface drip irrigation led to better agronomical performance yet the conventional irrigation showed a contrasting result. Sugarcane productivity under surface drip irrigation, sub-surface drip irrigation, and conventional irrigation were 81.29, 110.33, and 69.25 tons ha<sup>-1</sup>, respectively. Meanwhile, in clay soil, there were no prominent differences of agronomic parameters between all irrigation treatments. Sugarcane productivity under surface drip irrigation, sub-surface drip irrigation, and conventional irrigation were 79.03, 60.58, and 78.16 tons ha<sup>-1</sup>,respectively. The water cost used to produce one kg of sugarcane biomass under conventional irrigation, surface drip irrigation, and sub-surface drip irrigation in sandy soil were IDR 169, IDR 103, and IDR 87, while the cost in clay soil were IDR 443, IDR 218, and IDR 293, respectively.<strong></strong></p><strong><em>Abstrak</em>. </strong>Pertumbuhan dan produksi tebu (<em>Saccharum officinarum</em> L.) dipengaruhi oleh ketersediaan air. Kekurangan air dalam budidaya tebu dapat dipenuhi melalui irigasi. Dalam melakukan irigasi, penting untuk mengetahui kebutuhan air tebu dan tekstur tanah karena kedua faktor tersebut mempengaruhi efisiensi irigasi. Hingga saat ini, irigasi tetes merupakan salah satu jenis irigasi yang paling efisien dalam pertanian. Studi ini bertujuan untuk mengetahui performa agronomis serta keuntungan ekonomis berbagai metode irigasi pada tanaman tebu yang ditanam di tanah bertekstur pasir (di Kediri) dan lempung (di Pasuruan). Perlakuan irigasi pada penelitian ini yaitu irigasi tetes permukaan, irigasi tetes bawah permukaan, dan irigasi konvensional, dimana irigasi konvensional yang diberikan melalui parit menjadi perlakuan kontrol. Desain percobaan menggunakan Rancangan Acak Kelompok Lengkap, dengan tiga ulangan. Pada tanah pasir, performa agronomis tebu pada perlakuan irigasi tetes permukaan dan bawah permukaan lebih baik daripada irigasi konvensional. Produktivitas tebu pada irigasi tetes permukaan, irigasi tetes bawah permukaan, dan konvensional di tanah pasir masing-masing sebesar 81,29 ton ha<sup>-1</sup>, 110,33 ton ha<sup>-1</sup> dan 69,25 ton ha<sup>-1</sup>. Pada lokasi percobaan di tanah lempung, tidak ada perbedaan agronomis tebu yang signifikan antar perlakuan irigasi. Produktivitas tebu pada irigasi tetes permukaan, irigasi tetes bawah permukaan, dan konvensional di tanah lempung masing-masing sebesar 79,03 ton ha<sup>-1</sup>, 60,58 ton ha<sup>-1</sup>, dan 78,16 ton ha<sup>-1</sup>. Biaya air yang digunakan untuk memproduksi satu kilogram tebu dengan perlakuan irigasi konvensional, irigasi tetes permukaan, dan irigasi tetes bawah permukaan di tanah pasir masing-masing sebesar IDR 169, IDR 103, dan IDR 87, sedangkan di tanah lempung masing-masing sebesar IDR 443, IDR 218, dan IDR 293.
