“…While tomato yield increase from reduced irrigation to normal irrigation was only 11.0%. Similar results were observed by Liu et al [8] when compared to nonirrigation, drip irrigation increased tomato fruit size by 32%. This marked influence of irrigation on tomato fruit size was also reported by others [9].…”

“…This marked influence of irrigation on tomato fruit size was also reported by others [9]. Irrigation also increased total fruit yield by 66% and marketable fruit yield by 127%, while it decreased soluble solids content by 19% [8]. The negative influence of irrigation on soluble solid levels of tomato fruit and dry matter was also observed in other experiments [10].…”

“…Liu et al [8] found that drip irrigation decreased lycopene content by 8% compared to nonirrigation, with no effects on dry biomass of stems and leaves. While according to the findings of Riggi et al [16], higher amounts of lycopene were measured in the well watered treatment, regardless of the ripening stage, or the parameter unit used (dry or fresh matter).…”

A two-year (2010 and 2011) open field experiment was conducted to study the effect of drip irrigation and seasonal variation on the yield parameters and main bioactive components, carotenoids (mainly all trans, cis lycopene, and β-carotene), polyphenols (chlorogenic acid, caffeic acid, gallic acid, quercetin, rutin, naringin, etc.), and tocopherols of processing Strombolino F1 cherry tomatoes. The irrigated plants (STI) gave a higher marketable yield (61% and 101% respectively), and rain fed plants showed a yield loss. Water supply had a strong positive (R2=0.98) effect on marketable yield in 2011, but weak (R2=0.69) in 2010. In both years, the antioxidant concentration (all carotenoids, total polyphenols, tocopherols) showed a decrease with irrigation. Water supply affected the composition of carotenoids to a considerable extent. The optimum water supply treatment gave a lower proportion of lycopene than the rain fed control (STC) treatment. We observed significant negative correlation between rutin concentration and irrigation. The α-tocopherol concentration was significantly higher in STC treatments. Irrigation negatively influenced antioxidant concentrations of cherry tomato fruits, but higher yield could account for the concentration loss of individual fruits by higher antioxidant production per unit area.

“…Otherwise, ditch depth was found to have slight effects on WUE, this was probably due to the fact that different ditch depth resulted in different profile distributions of soil moisture. Besides, the negative relationship between irrigation quota and overall tomato quality in our study agreed with the results by many early studies (Liu et al, 2011;Patanè et al, 2011).…”

Various indexes should be considered when developing a suitable irrigation and drainage scheme for crops. Our study chosen tomato as plant material and conducted a field experiment under saline soils. Nine treatments distinguished by different irrigation quotas and different drain ditch depths were used for the optimization of irrigation-drainage scheme. A flooding irrigation treatment with no surface drainage was adopted as control. The system of evaluation indexes was established in comprehensive consideration of the electrical conductivity and nutrient of soil, and the water use efficiency, nitrogen use efficiency, quality and marketable yield of tomato. Moreover, the multi-index analysis and projection pursuit (PP) model were used to evaluate the irrigation-drainage schemes according to the observed values of these six evaluation indexes. Results showed that different irrigationdrainage treatments decreased the electrical conductivity in plough layer by 24.6-51.3%, and increased the tomato water use efficiency and nitrogen use efficiency by 0.3-24.2% and 20.3-96.0%, respectively. The tomato marketable yield was increased by 14.4-31.3% with the irrigation-drainage treatments when compared to the control. As analyzed by the PP model, I3D1 (300 m 3 hm -2 of irrigation quota combined with 10 cm of ditch depth) was the treatment that possessed best comprehensive benefits due to the highest projection value of 1.6724 thus was recommended by this study as the optimal irrigation-drainage scheme.

Shortage of water or nutrient supplies can restrict the high nitrogen (N) demand of processing tomato, leaving high residual soil N resulting in negative environmental impacts. A 4-year field experiment, 2006-2009, was conducted to study the effects of water management consisting of drip irrigation (DI) and non-irrigation (NI), fertilizer phosphorus (P) rates (0, 30, 60, and 90 kg P ha -1 ), and fertilizer potassium (K) rates (0, 200, 400, and 600 kg K ha -1 ) on soil and plant N when a recommended N rate of 270 kg N ha -1 was applied. Compared with the NI treatment, DI increased fruit N removal by 101 %, plant total N uptake by 26 %, and N harvest index by 55 %. Consequently, DI decreased apparent field N balance (fertiliser N input minus plant total N uptake) by 28 % and cumulative post-harvest soil N in the 0-100 cm depth by 33 %. Post-harvest soil N concentration was not affected by water management in the 0-20 cm depth, but was significantly higher in the NI treatment in the 20-100 cm depth. Fertilizer P input had no effects on all variables except for decreasing N concentration in the stems and leaves. Fertilizer K rates significantly affected plant N utilization, with highest fruit N removal and plant total N uptake at the 200 kg K ha -1 treatment; therefore, supplementing K had the potential to decrease gross N losses during tomato growing seasons. Based on the measured apparent field N balance and spatial distribution of soil N, gross N losses during the growing season were more severe than expected in a region that is highly susceptible to post-harvest soil N losses.
