“…A number of studies have reported a reduction in tomato plant height especially under low rainfall (Dry, 1998). The reduction in plant height is a common phenomenon among plants that are sensitive to moisture stress, as a result of low rainfall (Shao, 2014). In tomato, the roots are severely affected by low soil moisture due to reduced root permeability and hydraulic conductivity, which in turn affects uptake and transport of nutrients supplied by fertilizers (Huang, 2000).…”

Less or no fertilizer use compromises growth and yield of cherry tomato (Solanum lycopersicum var. Cerasiforme) in Uganda. A study was conducted to determine the effect of nitrogen (N) and potassium (K) fertilizer rates on cherry tomato growth and yield. The experiment was conducted in a field during 2016B and 2017A seasons at Namulonge. The treatments included; (100, 60, 100) and (200, 60, 200) kg ha-1 of N, P, K and the control with no fertilizer application, these were laid out in a split plot design with three replications. Results revealed that tomato plants significantly (P < 0.05) responded to nitrogen and potassium fertilizer application by increasing their height and yield. The highest tomato height and yield were obtained from plots applied with 100, 60, 100 kg ha-1 of N, P and K. This rate was considered as the optimal application rate because plants applied with fertilizer above this rate were observed to have low height and yield. On the other hand, plants applied with nitrogen and potassium fertilizers below 100, 60, 100 kg ha-1, flowered and matured earlier than those in the control plots. The study showed that N and K fertilizer influenced plant height, flowering, maturity period and yield of cherry tomato. Based on these findings, use of 100, 60, 100 kg ha-1 of N, P and K is recommended for improving cherry tomato production in central Uganda, where the study was conducted, and any fertilizer rate above 100, 60, 100 kg ha-1 in the same area may be un-economical to use in cherry tomato growing.

“…Hou [70] adopted the projection pursuit model to select the best drip irrigation scheme for crop. Other methods, such as principal component analysis, entropy weight coefficient model were also used for guiding the agricultural production [71]. The essence of these models was the same, namely realizing the reduction of high-dimensional data.…”

To investigate better saline water irrigation scheme for tomatoes that scheduling with the compromise among yield (Yt), quality, irrigation water use efficiency (IWUE) and soil salt residual, an experiment with three irrigation quotas and three salinities of irrigation water was conducted under straw mulching in northern China. The irrigation quota levels were 280 mm (W1), 320 mm (W2) and 360 mm (W3), and the salinity levels were 1.0 dS/m (F), 3.0 dS/m (S1) and 5.0 dS/m (S2). Compared to freshwater, saline water irrigations decreased the maximum leaf area index (LAIm) of tomatoes, and the LAIm presented a decline tendency with higher salinity and lower irrigation quota. The best overall quality of tomato was obtained by S2W1, with the comprehensive quality index of 3.61. A higher salinity and lower irrigation quota resulted in a decrease of individual fruit weight and an increase of the blossom-end rot incidence, finally led to a reduction in the tomato Yt and marketable yield (Ym). After one growth season of tomato, the mass fraction of soil salt in plough layer under S2W1 treatment was the highest, and which presented a decline trend with an increasing irrigation quota. Moreover, compared to W1, soil salts had a tendency to move to the deeper soil layer when using W2 and W3 irrigation quota. According to the calculation results of projection pursuit model, S1W3 was the optimal treatment that possessed the best comprehensive benefit (tomato overall quality, Yt, Ym, IWUE and soil salt residual), and was recommended as the saline water irrigation scheme for tomatoes in northern China.

“…According to Nahar and Gretzmacher [1], glucose, fructose, sucrose, malic acid, ascorbic acid and citric acid content increased significantly with water stress and sweetness of tomatoes and quality enhanced. Another finding suggested as decreased level of irrigation exerted beneficial effects upon fruit quality, mostly with respect to total soluble solid and soluble sugar contents [22].…”

Tomato is one of the vegetable crops of worldwide demand because of its various purposes including nutritional and medicinal values. It produced in Ethiopia largely for domestic consumption by small scale farmers and private producers. Tomato production and productivity affected by biotic and abiotic factors. Water quality and deficit irrigation has been considered as factor in its production, yield and quality as reported by many authors worldwide. Salinity, toxicity of heavy metals, temperature, microorganisms and presence of organic matters are some concern of water quality that influence tomato yield and quality. Use of municipal waste water for irrigation enhances toxic elements that further affect human health and several reports indicated that industrial waste water has to be treated before using for irrigation. Irrigation management practices such as amount, time of application and frequency of water affect tomatoes yield and quality. Deficit irrigation with its several advantages affects negatively tomato yield but it increases fruit quality. Hence, based on reports of scientific findings, effects of these two factors reviewed in this paper for further information provision.
