An experiment was conducted in wooden boxes to evaluate water use efficiency, biomass production, nitrogen and potassium uptake and yield of tomato plants (Lycopersicon esculentum) grown under flood irrigation (FI) and surface drip irrigation (SDI). Leaf area, leaf area index, biomass production and yield of tomato plants were significantly (P<0.05) higher in SDI than FI treatment. Biomass production (g/plant) was 53.3 and 42.2 and yield of tomato (kg/plant) was 1.27 and 0.99 in SDI and FI treatments, respectively. Surface drip irrigation increased water use efficiency (Kgm-3) of tomato plants by two fold (37.88) compared to flood irrigation ( 19.88). Significantly (P<0.05) higher concentrations of nitrogen in leaf (3.22%) and stem (2.62 %) were measured for tomato plants grown under SDI than FI (2.63 and 2.19 %). Potassium concentrations on the other hand, showed no significant differences. DOI: http://dx.doi.org/10.3329/jasbs.v38i2.15611 J. Asiat. Soc. Bangladesh, Sci. 38(2): 207-215, December 2012

Surface Drip Irrigation

An experiment was conducted in wooden boxes to assess flood, surface and sub-surface drip irrigation on biomass production, nutrient content and water use efficiency of maize (Zea mays L.). Four levels of irrigation treatments were applied: (i) SD1 = Drip irrigation pipe was set up on the surface of the soil ; (ii) SSD2 = Drip irrigation pipe was buried up to 5 cm depth; (iii) SSD3 = Drip irrigation pipe was buried up to 7.5 cm depth and (iv) FI = Flood irrigation was practiced without any drip irrigation pipe. Leaf area, leaf area index and biomass production of maize were significantly (p < 0.05) higher in SSD3 than SSD2 and FI treatments. Biomass production was 37.2, 41.1, 54.2 and 35.2 g in SD1, SSD2, SSD3 and FI treatments, respectively. Water use efficiency (WUE) was also significantly (p < 0.05) higher in surface and sub-surface drip irrigation than flood irrigation. Values for WUEs were 0.248, 0.298, 0.430 and 0.156 kg/m3 in SD1, SSD2, SSD3 and FI treatments, respectively. As a result, all three drip irrigation treatments enhanced water use efficiencies than flood irrigation. Comparing the three drip irrigation treatments, significantly (p < 0.05) higher nitrogen was found both in leaf and stem (3.3 and 3.8%) in sub-surface drip irrigation at 7.5 cm depth than flood irrigation (2.2 and 1.4%). Although, potassium contents in leaf and stem were not significantly different between the treatments, but had a tendency to be higher in drip irrigation treatments. Above all, drip irrigation performed better with higher water use efficiency. Dhaka Univ. J. Biol. Sci. 22(1): 47-54, 2013 (January)

Groundwater plays a major role in agro-hydrological processes in the North China Plain (NCP). The NCP is facing a water deficit, due to a rapid decline in the water table because of the double cropping system. A two crop (maize and wheat) rotation is required to balance the food supply and demand, which leads to an imbalance between evapotranspiration (ET) and precipitation. Thus, there has been a decline of about 1.35 m yr−1 of groundwater (Luancheng Agroecosystem Experimental Station (LAES), NCP) during the last 10 years. Lysimeter experiments were conducted under different irrigation treatments (flood, surface drip, and subsurface drip) to account for ET in the selection of a suitable irrigation method. Subsurface drip irrigation reduced ET by 26% compared to flood irrigation, and 15% compared to surface drip irrigation, with significant grain yield and biomass formation due to decreased evaporation losses. Grain yield, yield components, and above ground biomass were similar in subsurface drip and flood irrigation. However, these biomass parameters were lower with surface drip irrigation. Furthermore, subsurface drip irrigation increased the crop water productivity (24.95%) and irrigation water productivity (19.59%) compared to flood irrigation. The subsurface irrigated plants showed an increase in net photosynthesis (~10%), higher intrinsic water use efficiency (~36%), lower transpiration rate (~22%), and saved 80 mm of water compared to flood irrigation. Our findings indicate that subsurface drip irrigation can be adopted in the NCP to increase water use efficiency, optimize grain yield, and minimize water loss in order to address scarcity.

Tomato is one of the important vegetable crops for nutrition security. The vegetables respond very well to proper irrigation water management towards increasing yield. A study on response of tomato under subsurface drip irrigation (SDI) with laterals placed at 5 cm, 10 cm and 15 cm depth below soil surface was carried out in inceptisols at ICAR- Indian Institute of Vegetable Research, Varanasi. It was found that soil water content variation was less and more favorable within top 30 cm depth of soil profile under SDI with lateral placed at 10 cm depth below soil surface. The maximum yield of tomato 52.85 t/ha was realized under SDI with lateral placed at 10 cm depth below soil surface followed by yield under 15 cm and 5 cm depth of lateral placement. It was 14.67% higher than the surface drip irrigation. The lowest yield of tomato was recorded 46.09 t/ha with surface drip irrigation. Maximum water use efficiency 1.968 t/ha-cm was obtained with SDI lateral placed at 10 cm depth below soil surface. To realize maximum yield and water use efficiency of tomato, SDI laterals could be placed at 10 cm depth below soil surface.

Jujube tree yields in dryland saline soils are restricted by water shortages and soil salinity. Converting traditional flood irrigation to drip irrigation would solve water deficit and salt stress. The root distribution reacts primarily to the availability of water and nutrients. However, there is little information about the response of jujube roots to the change from flood irrigation to drip irrigation. In this context, a two–year experiment was carried out to reveal the effects of the change from long–term flood irrigation to drip irrigation on soil water, root distribution, fruit yield, and water use efficiency (WUE) of jujube trees. In this study, drip irrigation amounts were designed with three levels, i.e., 880 mm (W1), 660 mm (W2), 440 mm (W3), and the flood irrigation of 1100 mm was designed as the control (CK). The results showed that replacing flood irrigation with drip irrigation significantly altered soil water distribution and increased soil moisture in the topsoil (0–40 cm). In the drip irrigation treatments with high levels, soil water storage in the 0–60 cm soil layer at the flowering and fruit setting, and fruit swelling stages of jujube trees increased significantly compared with the flood irrigation. After two consecutive years of drip irrigation, the treatments with higher irrigation levels increased root length density (RLD) in 0–60 cm soil depth but decreased that in the 60–100 cm depth. In the horizontal direction, higher irrigation levels increased RLD in the distance of 0–50 cm, while reducing RLD in the distance of 50–100 cm. However, the opposite conclusion was obtained in W3 treatment. Additionally, in the second year of drip irrigation, W2 treatment (660 mm) significantly improved yield and WUE, with an increasing of 7.6% for yield and 60.3% for WUE compared to the flood irrigation. In summary, converting flood irrigation to drip irrigation is useful in regulating root distribution and improving WUE, which would be a promising method in jujube cultivation in arid regions.
