Nutritive Solution

Tomato fruits are a unique functional food and a natural reservoir of nutrients, antioxidants, vitamins and bioactive compounds that improve nutrition and human health. As an important vegetable throughout the world, tomatoes have attracted the attention of researchers to carry out various strategies to improve the functionality of this food aimed at the prevention of diseases, health and global well-being. An agronomic strategy in this study was to evaluate the influence of the application of "salicylic acid (SA)" on the yield and nutraceutical quality of the tomato crop, produced under hydroponic conditions. A completely randomized experimental design with six repetitions was used. SA at five doses (0.025, 0.05, 0.075, 0.1 and 0.125 mM) and one control were applied every 15 days in the nutritive solution under a hydroponic system on tomato plants. The evaluated variables were yield (total fruit weight per plant), fruit parameters (weight, diameter, firmness, and total soluble solids), percentage of weight loss and nutraceutical quality of tomato. The results obtained indicate that the addition of salicylic acid in nutritive solution increased the yield and biosynthesis of phytochemical compounds in tomato fruits, in relation to the control without application. In conclusion, to obtain a higher nutraceutical quality without affecting the tomato fruit yield, it is recommended to use the average concentration (0.125 mM) of SA.

The use of elicitors or biostimulants such as salicylic acid (SA) is an emerging novel practice to improve the yield and quality of crops since it plays an important role in the regulation of various physiological and metabolic processes. The objective of this research was to study the effect of the foliar application of SA on the nutraceutical quality and yield of tomato fruits. A completely randomized experimental design with 10 repetitions was used. SA was applied at five doses (0.025 mM, 0.05 mM, 0.075 mM, 0.1 mM, and 0.125 mM) every 15 days through foliar sprays after transplantation, accumulating seven applications through the cycle. The response variables were yield (total fruit weight per plant), fruit parameters (weight, diameter, firmness, and total soluble solids), percentage of weight loss, and nutraceutical quality. The obtained results suggest that the foliar spraying of SA improves the yield and biosynthesis of phytochemical compounds in tomato fruits, compared to control plants. According to the results, it is advisable to use the dose of 0.125 mM of SA since it has a higher content of bioactive compounds without compromising yield.

The present work had as objective to evaluate the physical-chemical characteristics of commercial tomato fruits grafted on different solanaceous species. The experiment was conducted in a greenhouse, in a randomized complete block design, with four blocks and six treatments, being the rootstocks: cocona (Solanum sessiliflorum); two cultivars of eggplant (Solanum aethiopicum), Long Light Green and Big Hill; jurubebão (Solanum lycocarpum) and jurubeba juna (Solanum stramonifolium), grafted with the tomato cultivar Santa Cruz Kada, and the control treatment was represented by the self-grafted tomato. Three consecutive harvests were spaced seven days after the production stabilization, and the characteristics fruits analyzed were Total Soluble Solids (ºBrix), pH, Titratable Acidity (percentage of citric acid) and TSS/TA. A statistically significant difference was found in the Tukey’s test at 5% probability in the titratable acidity, pH and fruit pulp flavor, among the evaluated treatments, while the soluble solids content did not differ between treatments in any of the harvests, but the values remained within the considered adequate for the tomato in natura in the current literature. There was a decrease in fruit flavor in all treatments, and fruit pH drop in all treatments with the exception of jurubebão, with the advancement of plant age, while the titratable acidity had an inverse behavior. The evaluated rootstocks can be used in the tomato crop, without prejudice to the quality of the tomato fruit produced.

The effect of a saline nutritional regime on tomato (Lycopersicon esculentum Mill.) fruit yield and fruit quality enhancement for five cultivars (CLN 425, Pearson, Napoli, Hymar, and Sierra) was studied. The saline nutrient treatment consisted of (i) a control. Hoagland's solution (EC=2.5 mScm -1), (ii) Hoagland's solution + 50 mM NaCl (EC=7.46 mScm-1), (iii) Hoagland's solution + 50 mM NaCl + 4 mM K2SO4 + 2 mM H3PO4 (EC=8.31mScm-1), (iv) same as in (iii)3 but applied when plants were at 50% flowering, then the plants were irrigated with Hoagland’s solution as in the control, and (v) same as in (iii) until the plans were at 5096 flowering, thereafter NaCl concentration was reduced to 25mM (EC=5.87 mscm-1). Plans were seven weeks old at the start of the saline treatments. Each plant was in PVC cylindrical pots (15 cm diameter and 27 cm height) containing washed quartz sand. Fruits were harvested once weekly for ten weeks at incipient red. The control gave a higher fruit  yield than the saline treatments. However, the tomato fruits from thesaline treatments had higher titratable acidity, higher total soluble solids, and higher total solid indicating better quality of the fruits than those from the control. Of the five cultivars studied, Hymar had the highest fruit yield followed by Pearson. Hymar’s quality was also highest, followed by CLN 425. Napoli was the most susceptible to salinity and Sierra had the lowest quality.

ABSTRACT The tomato crop plays an important environmental, economic and even social role, especially for creating employment and income. The present work aims to evaluate the effects of potassium (K) drip fertigation and of conventional K fertilization on the tomato crop quality. The experiment was conducted under field conditions, in the period between August 2011 and December 2011, in Fortaleza, CE, Brazil. The experimental design was in randomized blocks in a factorial arrangement and the treatments corresponded to doses (D1 = 200, D2 = 400 and D3 = 800 kg K2O ha-1) and K fertilizing methods (F1 - Fertigation and F2 - Conventional fertilization), plus an additional control (without K fertilization) for each fertilizing method, with four replicates. The following variables were analyzed: fruit firmness (FF), soluble solids content (SS), titratable acidity (TA), pH and SS/TA ratio. K fertilization through fertigation (400 kg K2O ha-1) increases SS and the SS/TA ratio of the tomato fruits. Thus, K fertigation is the most promising method, since it allows the use of a lower K dose.

The aim of this research is to evaluate the effect of foliar application of salicylic acid (SA) on the yield and phytochemical content in hydroponically grown cucumber (Cucumis sativus L.). (1) Background: The importance of Mexico’s cucumber production is based on its cultivation in recent decades as one of the major winter crops; in addition, the production of vegetables under hydroponic systems has increased significantly during the last few years, with cucumber being one of the vegetables with a high economic potential. (2) Methods: A completely randomized experimental design with 15 repetitions was used. SA at five doses (0.075, 0.1, 0.15, 0.25, and 0.5 mM) and one control (distilled water) was sprinkled weekly on cucumber plants. The evaluated variables were yield (total fruit weight per plant), fruit parameters (length, size and firmness), and nutraceutical quality of cucumber. (3) Results: Low concentrations of SA improve the yield and high concentrations decrease it, but the nutraceutical quality of fruits is improved, as compared to the control treatment. (4) Conclusions: In order to obtain a higher content of bioactive compounds without affecting the yield and commercial quality of cucumber fruits, it is advisable to use the average concentration (0.15 mM) of SA.

The Impact

ABSTRACT Five experiments were conducted to evaluate the hypothesis that Solanum americanum density and time of coexistence affect the quality of processing tomato fruit. The tomato crop was established using either the direct drilling or the transplanting technique. The factors evaluated consisted of weed density (from 0 up to 6 plants m-2) and time of weed interference (early bloom stage, full flowering stage, fruit filling, and harvest time). The effects of competition on tomato fruit quality were analysed using a multiple model. Tomato variables evaluated included industrial fruit types (which depended on ripeness and disease infection) and soluble solids level(obrix). Tomato fruit quality is dependent on the factors tested. Under low densities (< 6 plants m-2) of S. americanum there was a small impact on the quality of the tomato fruits. The percentage of grade A (mature fruit with red color and without pathogen infection) tomato fruits is the variable most affect by the independent variables. The impact of these independent variables on the percentage of grade C (green and/or with more than 15% disease infection) tomato yield was of smaller magnitude and in an inverse trend as the observed for grade A. The level of soluble solids was influenced by the weed interference on only two experiments, but the impact was of small magnitude. The impact of the results on current and future crop management practices is discussed.

The study was conducted to assess the effect of different waxing materials on the quality attributes of tomato fruits. A 2 x8 factorial experiment layout in complete randomized design with 16 treatment combinations and 3 replication was adopted.The materials that were used for the experiment are two (2) varieties of tomatoes (Pectomech and Power Rano) and seven(7) waxing material (shea butter, cassava starch, beeswax, and a combination of shea butter + cassava starch, shea butter + beeswax, cassava starch + beeswax, shea butter + cassava starch + beeswax) and a control. Results from the experiment indicated that all waxing treatments delayed the development of weight loss, firmness, pH, total soluble solids, and total titrable acidity. The results also suggested that edible wax coatings delayed the ripening process and colour development of tomato fruits during the storage period and extended the shelf life. However Beewax treatment and its combinations performed better than the other treatments. It was therefore recommended that locally produced wax such as Beewax, Shea butter, Cassava Starch treatments and their combinations could be a good technology for preserving the quality and extending the shelf life of fresh tomato fruit as well as maintaining the physical and chemical properties.

In agricultural production, nitrogen loss leads to economic loss and is a high environmental risk affecting plant growth, yield, and quality. Use of the N fertilizer with a urease inhibitor is thus necessary to minimize N losses and increase the efficiency of N. This study aimed to evaluate the effects of N-(n-butyl) Thiophosphoric Triamide (NBPT) on the growth, yield, and quality of pineapple. The experiment involved two foliar fertilizer treatments: 1% (w/v) urea solution with NBPT (2.25 mL kg−1 urea) was treated as NLU (NBPT Liquid Urea), and the same concentration of urea without NBPT served as the control. Both were applied 12 times, starting 1 month after planting (MAP) and continuing once a month for 12 months. The application of urea with NBPT notably increased the above-ground dry biomass per plant (20% and 10% at 8 and 12 MAP, respectively), leaf area per plant (23% and 15% at 8 and 12 MAP, respectively), N accumulation per plant (10%), PFPN (Partial Factor Productivity) (13%), and average fruit weight (15%) compared to the treatment with urea alone (control). The analysis of quality parameters indicated that urea with NBPT improves TSS (Total Soluble Solids) (19%), ascorbic acid (10%), and sucrose (14%) but reduces the total organic acid content (21%) in pineapple. When using urea with a urease inhibitor (NBPT), there was a significant improvement in growth, yield, quality, and nitrogen use efficiency, with the additional benefit of reduced nitrogen losses, in combination with easy handling. Hence, urea with a urease inhibitor can be used as a viable alternative for increasing pineapple yield by boosting growth with better fruit quality.

The strawberry cultivation is an important economic activity in the Rio Grande do Sul State, Brazil, however the number of offered cultivars to the growers is reduced. The yield and quality of strawberry (Fragaria x ananassa Duch.) cultivars Camarosa, Galexia, Earlibrite, Festival, Plarionfre and Sabrosa was evaluated under the climatic conditions of Pelotas, Rio Grande do Sul State. We determined the number, mass, total soluble solids (TSS ºBrix), total titratable acidity (TTA), antocianin level and fresh fruits produced in an experimental unit. We also determined the production of fruits per hectare and per plant. The statistical design used in the experiment was of completely randomized blocks with 6 treatments (cultivars) and 4 replicates where the experimental unit was composed of 8 plants. The harvest began in the first half of August, extending to the second half of December, totalling 20 weeks. Plarionfre, Earlibrite and Festival cultivars showed higher production from the first half of October until the end of the first half of November. Camarosa reached higher productivity, mass of plants and fruit weight. There were no differences between the evaluated cultivars in the levels of TSS, antocianin, ATT and pH during the period of evaluation.

Soils under intensive and successive cropping with central pivot irrigation tend to present high nutrient contents, especially phosphorus (P), which is a nutrient with a great impact on the yield and quality of agricultural products. Among the rotating crops, the application of high P rates is common in processing tomato, although not supported by research. This work evaluates the effect of phosphate fertilization (0, 200, 400, 600, 800, and 1000 kg ha-1 P2O5) on the yield and quality of industrial tomato ‘Heinz 9553’ grown in a soil with high available P content (145 mg dm-3) resulting of an intensive vegetables cultivation, which have high demand by P. The highest total (127.4 t ha-1) and commercial (108.6 t ha-1) yields were obtained with 413.9 and 384 kg ha-1 P2O5, respectively. The results showed that pH of tomato juice, the percentages of green, red, and commercial fruits were not influenced by the applied P rates. However, nutrient delivery increased the soluble solids content up to 356 kg ha-1 P2O5, which is interesting for tomato processing. After harvesting the fruits, the available soil P content was increased with P supply to the plants. For improvement of commercial yield and soluble solids characteristics, the tomato crop shall be fertilised with P even though the soil has high P content.
