Surface Drip Irrigation

The objective of this study was to reveal the regulatory mechanisms underlying the soil bacterial community of subsurface drip irrigation (SDI). The effect of different buried depths of drip tape (0, 10, 20, 30 cm) on the soil bacterial community in a tomato root-zone was investigated using high-throughput technology. Furthermore, the mutual effects of root growth, tomato yield and soil bacterial community were also analyzed to explore the response of root-soil interaction to the buried depth of drip tape. The results indicated that SDI (i.e., 10, 20 and 30 cm buried depths of drip tape) changed the soil bacterial community structure compared to surface drip irrigation (a 0 cm buried depth of drip tape). SDI with a 10 cm buried depth of drip tape significantly reduced the relative abundances of Proteobacteria, Chloroflexi, Gemmatimonadetes, Acidobacteria, Firmicutes and Planctomycetes, but significantly increased the relative abundances of Actinobacteria, Candidate_division_TM7 and Bacteroidetes. SDI of 20 and 30 cm buried depth significantly decreased the relative abundances of Roteobacteri, Actinobacteria and Planctomycetes, however, increased the relative abundances of Chloroflexi, Gemmatimonadetes, Acidobacteria, Firmicutes, Candidate_division_TM7 and especially some trace bacteria (for example Nitrospirae). Furthermore, under 20 cm or 30 cm of buried depth, the abundances of nitrogen metabolism and phosphonate and phosphinate metabolism based on the PICRUSt (Reconstruction of Unobserved States) method were significantly improved as well as soil porosity and root forks at 0-10 cm. These changes strengthened root-soil interaction and improved tomato yield per plant by 22.47% and 19.38% under 20 cm and 30 cm of buried depth, respectively, compared to surface drip irrigation. Therefore, the responses of bacterial community and root-soil interaction to drip tape buried depth of 20 cm and 30 cm are proven to be beneficial for the increasing of tomato production.

Subsurface Drip

This study aimed to integrate the ability of organic mulching (rice straw) and subsurface irrigation with deficit irrigation to save soil moisture content (SMC) and increase water use efficiency (WUE). A field experiment was carried out during 2019 on tomato crop in sandy soil. The variables included four levels of irrigation namely 70, 80, 90, and 100% of crop evapotranspiration (ETc) with three irrigation techniques which were subsurface drip irrigation (SSD), mulched surface drip irrigation (MD), and mulched subsurface drip irrigation (MSSD). The treatments of MSSD showed earlier maturity of tomato crop and longer picking period if compared to MD and SSD treatments. MSSD showed higher ability to save (SMC) than other irrigation techniques. Reduction of applied water from 100 to 70% ETc led to a decrease in tomato yield by 23.32% at MSSD compared to 28.47%, and 26.23% for MD, and SSD respectively. The highest WUE was at MSSD70 with 5.92 kg/m3 while the least was 4.21 kg/m3 with SSD100. The highest benefit/cost ratio was 9.03 with the treatment SSD70 while the highest profit of water unit was 2.19 US$/m3 with MSSD70. MSSD can be used with 90% of ETc without any significant difference in tomato crop while it can be used with 70% ETc to obtain higher WUE. The study recommended integrating rice straw mulching and subsurface drip irrigation with deficit irrigation as a strategy to save irrigation water and obtain the maximum possible benefits of water unit whether related to tomato yield or its revenue.

Germination And Growth

A field experiment was conducted near Davis, CA, during the 2003 and 2004 summer growing seasons to compare weed control, yield, and fruit quality in different irrigation and tillage systems in processing tomato. Trial design was a subplots with the main plots as subsurface drip irrigation or furrow irrigation, subplots were standard tillage or conservation tillage, and sub-subplots were herbicide or no herbicide. The hypothesis was that subsurface drip irrigation could limit surface soil wetting and thus inhibit germination and growth of weeds equal to or better than standard tillage and/or herbicides. In both 2003 and 2004, weed densities in the subsurface drip irrigation treatments were over 98% lower than the levels in furrow irrigation treatments. In addition, weed densities were lower in the subsurface drip–conservation till–no herbicide treatment than in any of the furrow irrigation treatments, including the furrow irrigation–standard tillage–herbicide treatments. The time required for a hand-hoeing crew to remove weeds was 5 to 13 times greater in furrow irrigation treatments compared to subsurface drip irrigation treatments. Weed biomass on beds at tomato harvest was 10 to 14 times greater in the furrow systems as compared to the subsurface drip irrigation systems. These results demonstrate the effectiveness of subsurface drip irrigation in controlling weed germination and growth, compared to tillage or herbicide applications. Tomato yield was higher in the subsurface drip irrigation treatment compared to furrow irrigation in 2004. Herbicide treatment increased yield in 2004, but only in the furrow irrigation treatment in 2003. Fruit brix level was not related to treatment in 2003, but was lower in the subsurface drip irrigation plots in 2004. These results indicate that subsurface drip irrigation can reduce weed competition in conservation tillage systems, without requiring herbicide applications.
