“…Figure 11 Total soluble solids, vitamin C, and titratable acidity for the different irrigation treatments Both RDI and PRD treatments had higher TSS concentrations than the FI treatment in both years, as shown in Figure 11. This agrees with the findings of various researchers [14,37,58] . TSS increasing could be due to a higher conversion of starch to sugars under water deficit [59] .…”

“…Veit-Köhler et al [13] found that small reductions in water supply resulted in higher quality tomato due to higher concentrations of sugars, titratable acidity (TA), and vitamin C (VC). Nangare et al [14] reported that although regulated DI did not affect the yield at RDI with 80% from FI, there was a loss of approximately one fourth of the marketable fruit yield with RDI with 60% from FI compared to the FI. In addition, they concluded that the quality parameters of the tomatoes, such as hardness, total soluble solid (TSS), acidity, and color, were considerably improved by DI.…”

Water resources are subjected to ever-increasing supply constraints due to extensive agricultural water demand for irrigated lands. Therefore, water-saving irrigation strategies need to be explored. The present study was conducted to explore the possibilities of using regulated deficit irrigation (RDI) and partial root zone drying irrigation (PRD) methods as water-saving irrigation techniques for subsurface irrigation. The objective of this study are to assess the effects of RDI and PRD irrigation on the water productivity of vegetable crops (tomato) under SSD systems in arid climatic conditions, and to compare the responses of tomato crops to PRD, RDI, and FI under an SSD system in terms of productivity, crop quality, and the amount of water saved. The field experiment was conducted during the fall 2014-2015 and 2015-2016 Citation: Hashem M S, El-Abedin T Z, Al-Ghobari H M.

“…In more recent studies and under more similar conditions, i.e., tomato cultivation in pots, WUE values higher than those presented by the above-mentioned authors have also been observed, such as in the study of Reina-Sánchez, Romero-Aranda and Cuartero (2005), who obtained a WUE of 25.0 kg m -3 . In general, the irrigation depth that promotes the greatest WUE is lower than the irrigation depth that promotes maximum yield (Nangare, Singh, Kumar, & Minhas, 2016), which justifies the use of deficit irrigation aiming at better WUE. However, this pattern was not observed in the present study because WUE was calculated based on the marketable yield, which was linearly influenced by the irrigation depths due to the losses caused by the incidence of fruits with blossom-end rot.…”

ABSTRACT.Two experiments were performed to evaluate the effect of ash (40, 80, and 120 g per plant), castor cake (140 and 280 g per plant) and water depth (135, 165, 191, and 213 mm) on the growth and production of organic tomato cultivated in pots in a greenhouse. The experimental design was randomized blocks, and the irrigation was managed using an automatic irrigation device. The following variables were evaluated: plant heights, numbers of leaves, bunches, flowers and fruits, total mass of fruits, mass of marketable fruits, mass of fruits with blossom-end rot, total diameter of fruits, and diameter of marketable fruits. Most of the growth variables showed gains with the application of 140 g of ash and 280 g of cake.The dose of 280 g of castor cake was responsible for the greatest mass of marketable fruits (1.78 kg per plant), regardless of the ash dose. The water deficit reduced values of most of the variables of growth and production. The irrigation depth of 213 mm was responsible for the greatest mass of marketable fruits (4.04 kg per plant). The highest water use efficiencies, 37.00 and 37.93 kg m -3, were observed at irrigation depths of 191 and 213 mm, respectively.Keywords: Solanum lycopersicum L., organic agriculture, water management.Crescimento e produção do tomateiro adubado com cinza e torta de mamona e sob lâminas de irrigação, cultivado em vasoponia orgânica RESUMO. Foram realizados dois experimentos com objetivo de avaliar o efeito da cinza (40, 80 e 120 g por planta), da torta de mamona (140 e 280 g por planta) e de lâminas de irrigação (135, 165, 191 e 213 mm) no crescimento e produção do tomateiro orgânico, cultivado em vaso e ambiente protegido. O delineamento experimental foi em blocos casualizados e o manejo da irrigação realizado pelo acionador automático para irrigação. Foram avaliadas a altura das plantas, os números de folhas, cachos, flores e frutos, as massas de fruto total, comercial e com podridão apical, e os diâmetros de fruto total e comercial. A maioria das variáveis de crescimento obtiveram ganhos com a aplicação de 140 g de cinza e 280 g de torta. A dose de 280 g de torta proporcionou maior massa fresca comercial (1,78 kg por planta), independente da dose de cinza. O déficit hídrico reduziu os valores da maioria das variáveis de crescimento e de produção. A lâmina de 213 mm foi a responsável pela maior massa fresca comercial (4,04 kg por planta). As maiores eficiências de uso de água, 37,00 e 37,93 kg m -3 , foram encontradas para as lâminas de 191 e 213 mm, respectivamente.Palavras-chave: Solanum lycopersicum L., agricultura orgânica, manejo da irrigação.

Background The increasing concentration of atmospheric CO2 not only affects the growing environment of crops but also aggravates the global greenhouse effect and further aggravates the problem of water shortage. The combined effect of water deficit and potassium (K) application has not been widely studied. Aims A pot experiment was conducted to investigate the effect of deficit irrigation (DI) and K application at different growth stages on carbon allocation and enzyme activities related to sugar metabolism. Methods Tomatoes were transplanted and planted on April 26, 2017 and harvested on August 15, 2017. Four irrigation regimes were implemented with two water levels (full irrigation‐W and DI‐W/2) in different growth stages, and each water treatment was equally divided into two subgroups: with K (K1) and without K (K0). Fruits from the first to fourth trusses of the tomato plants were sampled. Tomato growth, carbon allocation, and related enzyme activities were measured. Results The fresh weight (FW), dry weight, and relative growth rate of dry mass were sensitive to irrigation amount under K fertilization, enhancing the promotion effect of irrigation on fruit. Meanwhile, carbon allocation was sensitive to irrigation amount under K regime. Sucrose synthase (SuSy), acid invertase (AI), and sucrose phosphate synthase (SPS) were also highly sensitive to irrigation amount under K application condition. Starch phosphorylase displayed a quadratic parabola for irrigation amount, and adenosine diphosphate glucose pyrophosphorylase (AGPase) was highly sensitive to irrigation amount without K fertilization. Carbon in the form of other carbohydrates, carbon in the form of soluble sugar (Csol), and fruit water content were the factors that had the greatest influence on the principal components. Classification by K‐means algorithm and canonical correlation analysis showed that FW, fructose, sucrose, and starch could be used as significant indicators of the dry matter components of the fruit for the treatment without K. In the case of K regime, SuSy, AGPase, AI, and Csol could be used as a significant indicator of the correlation analysis of carbon metabolism activity. Conclusions The factors related to the improvement of fruit quality and carbon allocation by deficient irrigation and K application were explored. Water stress changed the distribution of photosynthetic carbon between starch and soluble sugar. K application further changed the balance between soluble sugars and other compounds. In particular, it significantly increased the carbon content of soluble sugars and decreased that of other compounds. AI and SuSy are key enzymes affecting carbon metabolism under water‐deficient conditions.
