Aim of study: We investigated water evaporation of the soil surface and the soil water distribution under different mulching techniques using subsurface drip irrigation (SDI) system.Area of study: The experiment was conducted at the Agricultural Research and Experimental Farm in Dirab, Riyadh, Saudi Arabia, locating 24.4195° N, 46.65° E, and 552 m altitude.Material and methods: The two types of soil surface mulching were black plastic film (BPF) and palm tree waste (PTW), with no mulching (NM) as control. The two drip line depths from the soil surface (DL) were 15 cm and 25 cm, and surface drip irrigation (DI) was the control.Main results: In SDI, the use of BPF or PTW mulching resulted in enhanced water retention capacity of the soil and an approximately 6% water saving, compared with NM. The amounts of water saved at DL of 15 cm (19-24 mm) were greater than those at DL of 25 cm (15-20 mm), whereas the DI used the highest amount of applied water. The distribution of soil water content for BPF and PTW were found to be more uniform than NM.Research highlights: It is advised to mulch the soil with PTW due to lower costs and through a DL of 15 cm.

The results of experimental researches on studying of features of formation of a water mode of soils, water consumption processes, and corn yield under different schemes of irrigation pipelines (IP) under subsurface drip irrigation (SDI) in the Steppe of Ukraine. The wetting zone of dark-chestnut residual-saline sandy soil (SI "SF "Brylivske") changed. There is a shift of the center relative to the drip water outlet into deeper horizons of the soil profile (up to 52 cm) with the increasing norm; soil layer 0-15 cm is almost not moistened, regardless of watering rate. At a distance of IP 1,0 m closing of wetting zones, occur at irrigation rates of 2,7 m3/100 running meter (r. m), and at a distance of IP 1,4 m does not occur even at irrigation rates of 3,7 m3/100 r. m, while the depth of wetting reaches 90 cm. The wetting zone of chernozem sandy loam on the loess species (SI "SF "Velyki Klyny") with irrigation rates of 2,7 m3/100 r. m was observed on the soil surface. The maximum depth of wetting, with irrigation norms of 3,7 m3/100 r. m, reached 70 cm with a maximum diameter of 79 cm at a depth of 25 cm. Closing of wetting zones was not observed. Studies at SI "SF "Brylivske" have confirmed that the depth of IP placement (on the soil surface or at a depth of 30 cm) influenced the formation of the soil water regime and the corn yield. The minimum total water consumption was 6271 m3/ha under drip irrigation (DI) (IP 1,4 m), 17 % more than SDI (IP 1,4 m), and 29% more than SDI (IP 1,0 m). The highest yield was obtained in the case of DI (IP 1,4 m) of 15,72 t/ha. SDI (IP 1,0 m) received 13,93 t/ha, and SDI (IP 1,4 m) received 13,50 t/ha. The distance between the IP in 1,0 m and 1.4 m of the SDI system did not significantly affect corn yield (13.93 and 13.50 t/ha, respectively), but at a distance of IP 1.4 m, the water consumption ratio was 6.8% less compared to IP 1,0 m. The value of the irrigation rate in the variants SDI (IP 1.0 m) was higher than SDI (IP 1,4 m) by 13,6 %. Therefore, in terms of irrigation water consumption and capital expenditures, the SDI (IP 1,4 m) is more economical. Experimental studies conducted in the SI "SF "Velyki Klyny" show that the depth of placement of IP (on the soil surface or at a depth of 20 cm) did not affect the corn yield. For DI (IP 1,0 m) the yield was 12,00 t/ha and for SDI (IP 1.0 m) was 12,10 t/ha, with a water consumption ratio of 533,8 m3/t, and for DI (IP 1,0 m) by 3,6 % more. The research results confirm the importance of the parameters of SDI system for the formation of soil water regime and, accordingly, the realization of the potential of varieties and hybrids of crops for their cultivation by SDI.

Subsurface Drip

In terms of water use efficiency, the traditional seepage irrigation systems commonly used in areas with high water tables are one of the most inefficient methods of irrigation, though some irrigation management practices can contribute to better soil moisture uniformity. Subsurface drip irrigation systems apply water below the soil surface by microirrigation, improving the water distribution and time required to raise the water table for seepage irrigation.

Two different irrigation systems, subsurface drip irrigation and furrow irrigation, are tested to investigate the level of viral contamination and survival when tertiary effluent is used in arid and semi-arid regions. The effluent was injected with bacteriophages of PRD1 and MS2. A greater number of PRD1 and MS2 were recovered from the lettuce in the subsurface drip-irrigated plots as compared to those in the furrow-irrigated plots. Shallow drip tape installation and preferential water paths through cracks on the soil surface appeared to be the main causes of high viral contamination in subsurface drip irrigation plots, which led to the direct contact of the lettuce stems with the irrigation water which penetrated the soil surface. The water use efficiency of the subsurface drip irrigation system was higher than that of the furrow irrigation system. Thus, subsurface drip irrigation is an efficient irrigation method for vegetable crops in arid and semi-arid regions if viral contamination can be reduced. Deeper installation of drip tapes, frequent irrigations, and timely harvests based on cumulative heat units may further reduce health risks by ensuring viral die-off under various field conditions.

MANEJO E PRODUÇÃO DE PALHADA DA CANA-DE-AÇÚCAR EM UM SISTEMA IRRIGADO POR GOTEJAMENTO SUBSUPERFICIAL PARA GERAÇÃO DE BIOETANOL   ANDERSON RAMOS DE OLIVEIRA1, WELSON LIMA SIMÕES1   1 Embrapa Semiárido, Rodovia BR-428, Km 152, s/n, Zona Rural, CEP 56302-970, Petrolina, PE, Brasil, e-mail: [email protected], [email protected]   RESUMO: Práticas agrícolas que contemplam a sustentabilidade do sistema de produção da cana-de-açúcar têm sido cada vez mais demandadas pela sociedade. A palhada disponibilizada na colheita da cana-de-açúcar, sem queima, pode ser utilizada para a cogeração de energia na forma de bioetanol. Assim, objetivou-se com este trabalho avaliar a produtividade de palhada de cana-de-açúcar e estimar o rendimento de bioetanol de segunda geração - E2G, em um sistema irrigado por gotejamento subsuperficial, sob diferentes percentuais de manutenção de palhada sobre a superfície do solo. O estudo foi desenvolvido na Usina Agrovale S.A., em Juazeiro, BA. Adotou-se o delineamento em blocos casualizados com cinco tratamentos, correspondentes aos percentuais de manutenção de palhada sobre o solo: 0, 25, 50, 75 e 100%, com quatro repetições, durante quatro ciclos de cultivo. Avaliou-se a produtividade de palhada remanescente após as colheitas e estimou-se o rendimento de bioetanol. A produtividade de palhada da cana-de-açúcar na colheita foi influenciada pela porcentagem de palhada remanescente mantida sobre o solo. A cultivar VAT90212 apresenta maior produtividade de palhada no ciclo de cana-planta. O rendimento de E2G proveniente da palhada aumenta o potencial de produtividade total de bioetanol de cana-de-açúcar por hectare.   Palavras-chave: E2G, sustentabilidade, bioenergia, Semiárido.   MANAGEMENT AND PRODUCTION OF SUGARCANE STRAW UNDER SUBSURFACE DRIP IRRIGATION FOR BIOETHANOL GENERATION   ABSTRACT: Sustainable agricultural practices in the sugarcane production system have been increasingly demanded by society. The amount of sugarcane straw available in the harvest, without burning, can be used as energy for second-generation bioethanol production. The objectives of this work were to evaluate the productivity of sugarcane straw and to estimate the yield of second-generation bioethanol, under subsurface drip irrigation, using straw at different percentages of soil surface coverage. The study was conducted at Agrovale S.A. in Juazeiro, BA, Brazil. A randomized block design with five treatments, corresponding to the levels of straw soil surface coverage was used: 0, 25, 50, 75, and 100%, with four replications, during four crop cycles. The yield of remaining straw on the soil after the harvest was evaluated and the yield of bioethanol was estimated. The yield of sugarcane straw at harvest was influenced by the percentage of remaining straw soil surface coverage. The cultivar VAT90212 shows higher straw productivity in the sugarcane plant cycle. The yield of the second generation bioethanol from the straw increases the total productivity potential of bioethanol from sugarcane per hectare.   Keywords: E2G, sustainability, bioenergy, Semi-arid.

Throughout much of the Southwestern United States, poor quality water and limited water resources require innovative methods to conserve water. No research to date has indicated whether seeded bermudagrass Cynodon dactylon can be established by using subsurface drip irrigation (SDI). In 2001 (Expt. I) and 2002 (Expt. II), seeded bermudagrass was evaluated for establishment using SDI. Treatments consisted of emitters and tubing spaced at 30, 46, and 61 cm. The control treatment consisted of pop-up sprinklers. Salinity accumulation is a concern when irrigating turfgrass in areas of poor water quality and low annual rainfall. Salinity accumulation was visible at the soil surface during establishment in 2001, but turfgrass showed no visible signs of stress due to salinity. In 2002, substantial rainfall reduced salinity accumulation during establishment as salinity was not present on the soil surface. Salinity accumulation was greater in most months at the 0-15 cm depth in both years compared to the 15-30 cm depth. Full turfgrass coverage (≥90%) for the control plots in 2001 was about 8.5 weeks and the SDI treatments had complete coverage in 10 weeks. Turfgrass coverage for all treatments in 2002 was 9 weeks. Expt. II had a slightly faster establishment rate due to greater rainfall and different soil characteristics than that of Expt. I. Root count and depth of roots for both years showed roots to 61 cm depth in all treatments. A general trend of higher salinity accumulation at the midpoint between tubing was seen in Expts. I and II. However, after significant rainfall salinity levels returned to concentrations comparable to initial soil salinity concentrations in both years. This research documents the ability to successfully establish seeded bermudagrass using SDI.
