“…Three irrigation treatments were surface drip irrigation (SDI), sub-surface drip irrigation (SSDI), and conventional irrigation (CI). SDI and SSDI were compared as previous studies reported an agronomic performance difference of various crops under both treatments (Martinez & Reca 2014;Umair et al 2019;Miyazaki & Arita 2020). Water in both SDI and SSDI treatment was released through drip line (emitter), and water in the CI treatment was applied through the open canal.…”

“…Overall, in Kediri, it can be known that the most positive agronomic performance was under the SSDI treatment. This may be attributed to an increase in water use efficiency due to less evaporation in the SSDI treatment than the other irrigation treatments (Hamada et al 2015;Umair et al 2019). Miyazaki and Arita (2020) observed that when the deeper the SSDI equipment is placed, the higher the root length and branching of sugarcane.…”

Abstract. Sugarcane (Saccharum officinarum 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-1, 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-1,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.Abstrak. Pertumbuhan dan produksi tebu (Saccharum officinarum 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-1, 110,33 ton ha-1 dan 69,25 ton ha-1. 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-1, 60,58 ton ha-1, dan 78,16 ton ha-1. 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.

“…The technical characteristics of SDI include small flow, local moistening, and frequent irrigation. When compared with surface irrigation methods, SDI has been found to have outstanding advantages, such as water conservation, lower amounts of required fertilizer, reducing evaporation losses, increasing crop WUE, irrigation WUE and crop yield, good adaptability to various terrain, uniform irrigation, and ease of technology integration [8][9][10][11][12][13][14][15].…”

A field experiment was conducted for the purpose of examining the effects of different combinations of water and fertilizer applications on the water consumption and yields of alfalfa under subsurface drip irrigation (SDI). The results showed that the jointing and branching stages were the key stages for alfalfa water requirement. The water consumption had varied greatly (from 130 to 170 mm) during the growth period of each alfalfa crop. The water consumption during the whole growth period was approximately 500 mm, and the maximum water consumption intensity was 3.64 mm·d-1. The overall changes in water consumption and yields during the growth period of the alfalfa displayed trends of first increasing and then decreasing. The sensitivities of the yields to water changes were much higher than that of fertilizer. The water use efficiency (WUE) of the alfalfa was determined to range from 1.68 to 3.20 kg·m-3, and the rate of growth had ranged from 4.85% to 51.77%. The WUE and rate of growth of the alfalfa indicated the following trend: second crop > third crop > first crop. The results of frequency analysis based on the water-nitrogen-yield regression equation are the following: irrigation amounts of 142~165 mm and nitrogen application of 61~80 kg·hm-2 have a 95% probability of obtaining a hay yield of alfalfa of more than 11903 kg·hm-2. These results suggest that SDI is a promising irrigation method, which can increase the WUE and hay yield of alfalfa under the condition of SDI within an appropriate amount of water and nitrogen fertilizer, and too low or too high water and nitrogen fertilizer will adversely affect the WUE and hay yield of alfalfa.

“…However, the time-lag effect was more sensitive to SWC below a certain value. This may be attributed to the fact that the water stored at W4 could not meet the demand of winter wheat transpiration during the day (Umair et al, 2019), and the stoma was only partially opened, so the peak Tc was delayed (Kaufmann, 1982). Meanwhile, LT was poorly correlated to daily SWC at W1, W2 and W3, but highly correlated at W4, indicating that the soil moisture was a determinant for the hysteresis when soil moisture was below a threshold.…”

Quantitative characterization of the time-lag effect between canopy temperature and atmospheric temperature and its controlling factors in the agricultural ecosystem may contribute to a higher inversion accuracy of soil water content using canopy-air temperature information. For this end, the canopy temperature (Tc) of winter wheat at four irrigation levels, W1 (field capacity of 95%), W2 (field capacity of 80%), W3 (field capacity of 65%) and W4 (field capacity of 50%), were continuously monitored, and the data of such environmental factors as solar radiation (Rs), atmospheric temperature (Ta), relative humidity (RH) and soil water content (SWC) were simultaneously collected. With the synchronous diurnal time series, the lag relationship between Tc and Ta was analyzed, and the lag time (LT) was calculated using time-lagged correlation analysis; multiple linear regression model was used to construct the time lag model based on factors of Rs, Ta, RH and SWC, and path analysis was used to study the interaction among the factors. The results showed: (1) hysteresis existed between Tc and Ta over the diel cycles, and different weather and irrigation levels did not change the direction of the time lag loop. (2) the key driver regulating the diel hysteresis pattern between Tc and Ta varied under different weather: on rainy days, key driver was Rs while on cloudy and sunny days, the key driver was RH. Meanwhile, SWC had some effect on hysteresis under a certain threshold.(3) the multiple regression model indicated that together Rs, Ta, RH, and SWC explained 68 ± 3, 48 ± 8, and 64 ± 3% of the variation of time-lag effect on rainy, cloudy, and sunny days, respectively. Path analysis showed that the key driver could enhance the time-lag effect through other indirect factors. These findings clearly indicated a dynamic process of time-lag effect between Tc and Ta with different weather and different irrigation levels. This study contributes to the understanding of the time-lag effect and its driving factors and this analysis provides the basis for further improvement on monitoring crop water deficit.
