“…For the longitudinal and equatorial diameter, the increase was directly proportional to the increase in the volume of water applied. The linear equation models obtained in this study are like those observed by other authors evaluating tomatoes' horticultural responses to different irrigation levels [42][43][44][45][46].…”

Precision irrigation is essential to improve water use efficiency (WUE), defined as the amount of biomass produced per unit of water used by plants. Our objective is to evaluate the effect of different soil volumetric water content (VWC) in plant growth, fruit yield, quality, and WUE of cherry tomatoes grown in a greenhouse. We tested four VWC thresholds (0.23, 0.30, 0.37, and 0.44 m3 m−3) to trigger a drip irrigation system in two tomato cultivars (‘Sweet Heaven’ and ‘Mascot F1′). The experiment was arranged in a split-plot design with four replications. We used capacitance sensors connected to an open-source, low-cost platform to monitor and control the irrigation in real-time based on demand. Plants were watered every time the soil VWC dropped below the set thresholds. The treatment with VWC 0.44 m3 m−3 resulted in the highest fruit yield, with 102.10% higher WUE when compared to the VWC 0.23 m3 m−3 in both cultivars. Fruit quality traits such as longitudinal and equatorial diameter increased asymptotically with soil water content. In contrast, treatments with deficit irrigation increased the fruit soluble solids by 15.73% in both cultivars. These results strongly suggest that accurate control of the soil VWC is essential to modulate the fruit yield and quality attributes in tomatoes produced in the greenhouse.

“…Being that cultivation in full sun influenced the closure of the stomata and sweating interruption. Santiago et al (2018), observed microclimatic and productive differences of cherry tomato under protected conditions in the region of Juazeiro-BA; associating the low productivity of the plants conducted in full sun to the high atmospheric demand. Which is characterized mainly by high incidence of solar radiation and low air humidity, since a high rate of evaporation, consequently reducing available water content and nutrients absorption.…”

Performance of crisphead lettuce cultivars under protected environment in different times of production 1The objective of this work was to evaluate the behavior of Crisphead lettuce as a function of production seasons under different forms of protected environment. Two experiments were carried out in the field at different times: September to December 2017 and June to August 2018, in a randomizaed blocks desing, in a 4 x 7 factorial scheme, the first one being production environments under shade nets: red screen, chromatinet ® screen, black screen and full sun, and the second, lettuce cultivars: Winslow, Irene, Balsamo, Rafaela, Iron Wood, Great Lakes and Delícia. The harvest was carried out at forty-two days after transplanting, where the following variables were analyzed: stem length (cm), total production and commercial productivity (t.ha -1 ). The data were submitted to analysis of variance, and a joint analysis was performed to analyze the treatments effect, then the means were compared by the Scott-Knott test, at 5% probability. The microclimate was altered in the shaded beds, which affected the cultivars development. The cultivation in protected environment provides higher productivity of Crisphead lettuce from September to December, at that time the cultivars Balsamo and Delicia were highlighted under chromatinet ® . In the period of mild temperatures, a better performance was observed for cv. Balsamo in full sun.

“…Tomato (Solanum lycopersicum L.) is one of the main vegetables produced in the world and among the different groups, cherry (S. lycopersicum var. cerasiforme) has the main characteristics of good productivity and higher concentration of soluble solids when compared to other groups (PÉK et al, 2014;SANTIAGO et al, 2018). Recent studies have shown the effect of B on cherry tomatoes, such as increased shelf life and vitamin C content (ISLAM et al, 2016;ISLAM et al, 2018).…”

The retranslocation of boron is influenced by the nutritional status of cherry tomato plants

Boron (B) retranslocation may confer greater tolerance to B deficiency or toxicity, resulting in plants and fruits with better nutritional quality. Most plants do not demonstrate phloem mobility for B; however, some plants have natural mobility and others express it under stress conditions, such as nutritional stress. Therefore, we investigated the phloem mobility of B in cherry tomato plants with different nutritional status. The plants were cultivated in nutrient solution with adequate and insufficient doses of Potassium (K) and B. Furthermore, the plants received foliar fertilization with B in a mature leaf (F) in a localized form. The B content and amount in leaves near F were compared with leaves of the same age and position on control plants. The experiment was carried out in a protected environment and conducted in a randomized complete block design in a subdivided plot scheme with four replicates. Re-translocation of B between neighboring leaves was observed when the plant was without K deficiency and with B deficiency. In this nutritional status, leaves next to fertilized leaf with B (F) showed higher B amount when compared to leaves of the same position of control plants. Evidence suggests that retranslocation of B over relatively short distances (between leaves) can be influenced by the nutritional status the cherry tomato plants.
