Tomato is considered as a valuable vegetable crop all over the world. It prefers loose, well drained loamy soils rich in organic matter. In Pakistan, mostly soils are calcareous in nature. In calcareous soils, the production of tomato crop is low because of zinc deficiency. Therefore, current study was aimed to examine the potential of foliar application of zinc oxide in tomato cultivar Tiny Tim Cherry in calcareous soil conditions. In the current study, all the studied traits i.e. plant height, stem diameter, number of branches per plant, number of leaves, number of flowers per plant, fruit weight and yield per plant were significantly higher after foliar application of zinc oxide (30 ppm) and significantly lower in controlled treatment as compared to other treatments of zinc oxide. The maximum total soluble solids (TSS), chlorophyll A, chlorophyll B, vitamin C, flavonoids, carotenoids and phenolics were recorded in plants treated with 30 ppm of zinc oxide as compared to other treatments. However, the highest acidity was calculated in 10 ppm, while the lowest acidity was measured in 0 ppm (control). Conclusively, foliar application of Zn has potential to increase the nutritional components of tomato fruits.

Florida produces the most vegetables in the United States during the winter season with favorable weather conditions. However, vegetables grown on calcareous soils in Florida have no potassium (K) fertilizer recommendation. The objective of this study was to evaluate the effects of K rates on leaf tissue K concentration (LTKC), plant biomass, fruit yield, and postharvest quality of tomatoes (Solanum lycopersicum L.) grown on a calcareous soil. The experiment was conducted during the winter seasons of 2014 and 2015 in Homestead, FL. Potassium fertilizers were applied at rates of 0, 56, 93, 149, 186, and 223 kg·ha−1 of K and divided into preplant dry fertilizer and fertigation during the season. No deficiency of LTKC was found at 30 days after transplanting (DAT) in both years. Potassium rates lower than 149 kg·ha−1 resulted in deficient LTKC at 95 DAT in 2014. No significant responses to K rates were observed in plant (leaf, stem, and root combined) dry weight biomass at all the sampling dates in both years. However, at 95 DAT, fruit dry weight biomass increased with increasing K rates to 130 and 147 kg·ha−1, reaching a plateau thereafter indicated by the linear-plateau models in 2014 and 2015, respectively. Predicted from quadratic and linear-plateau models, K rates of 173 and 178 kg·ha−1 were considered as the optimum rates for total season marketable yields in 2014 and 2015, respectively. Postharvest qualities, including fruit firmness, pH, and total soluble solids (TSS) content, were not significantly affected by K rates in both years. Overall, K rate of 178 kg·ha−1 was sufficient to grow tomato during the winter season in calcareous soils with 78 to 82 mg·kg−1 of ammonium bicarbonate-diethylenetriaminepentaacetic acid (AB-DTPA)-extracted K in Florida.

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.

Micronutrients applications are effective for better crop production in calcareous soils because these soils are usually deficit in iron (Fe), zinc (Zn) and boron (B). In Pakistan, most of soils are calcareous in nature. When tuberose is grown in such soils as a cut flower, its production is negatively affected. Therefore, a study was aimed to evaluate the effects of micronutrients as foliar sprays on cut tuberose production in calcareous soil. Micronutrients (Fe, Zn and B) alone and in combinations were sprayed on the plants after 60, 90 and 120 days of planting. The mixture of all these three micronutrients increased the plant height (95.77 cm), chlorophyll content (38.13 SPAD), number of leaves (79.63), leaf length (44.73 cm), fresh (111.64 g) and dry (16.16 g) plant weights, root length (15.13 cm), number of stalks (3.73), stalk length (79.03 cm), spike length (22 cm), number of florets (51.67), floret fresh weight (11.85 g), leaf Zn concentration (53.6 mg/g) and vase life (8.4 days). Fe + Zn enhanced the number of leaves (76.60), leaf length (45.83 cm), root length (15.05 cm), spike length (22.33 cm), and leaf Fe (128.18 mg/g) and Zn concentrations (55.02 mg/g). The Fe spray increased the leaf length (44.10 cm), days to flower initiation (142.47 days) and leaf Fe concentration (130.75 mg/g) in tuberose plants. Application of Zn improved the leaf length (45.87 cm) and diameter (1.32 cm), root (15.03 cm), spike (21.77 cm) and floret lengths (4.74 cm), floret dry weight (1.49 g) and leaf Zn concentration (57.5 mg/g). Foliar spray of B increased the B concentration (21.1 mg/g) in tuberose leaves. It is concluded that foliar application of micronutrients alone and in combinations improved the plant growth, flowering, leaf minerals concentrations and vase life of tuberose spikes. However, mixture of Fe, Zn and B was more effective as compared to other treatments. Moreover, current study encourages the foliar application of micronutrients in tuberose when grown in calcareous soils.

Many trials to supply germanium to fruit have been carried out since tests have confirmed germanium's role as a medical substance. Supplying germanium in orchards by soil and foliar application was not effective because of loss from rainfall. In order to increase germanium absorption by fruit, this study carried out tree trunk injections during the growing season. Two types of germanium, GeO (inorganic type) and Ge-132 (organic type), in concentrations of 5, 10, 25, and 50 mg·L–1 were supplied to `Niitaka' pear trees by trunk injection (1.5 L/tree), four times at 15-day intervals from June 2004. The treatment with 50 mg·L–1 GeO showed decreased fruit weight, but 50 mg·L–1 Ge-132 showed no difference to the control and other treatments. Fruit lenticels were increased in size by all of the Ge treatments in comparison to control fruit. Soluble solids as well as Hunter value `a' of the fruits of all Ge treatments were higher than that of the control. Flesh browning after peeling the fruit was delayed by the germanium treatment, and polyphenoloxidase (PPO) activities were lowered. Postharvest potentials were maintained at high levels for fruit firmness, physiological disorders, and decayed fruit during cold storage at 0 to 1 °C for 2 months.

Tomato Production

Growing vegetables can be seen as a means of improving people’s livelihoods and nutritional status. Tomatoes are one of the world’s most commonly planted vegetable crops. The nutritional arrangement of the tomato depends on the quantity and type of nutrients taken from the growing medium, such assoil and foliar application; therefore, an adequate amount of macro- and micro-nutrients, including zinc (Zn) and zinc oxide nanoparticles (ZnO-NPs), are crucial for tomato production. Zinc foliar spraying is one of the effective procedures that may improve crop quality and yield. Zinc oxide nanoparticles (ZnO-NPs) are represented as a biosafety concern for biological materials. Foliar application of Zn showed better results in increasing soluble solids(TSS), firmness, titratable acidity, chlorophyll-a, chlorophyll-b, ascorbic acid, amount of lycopene. Researchers have observed the effect of nanoparticles of zinc oxide on various crops, including tomatoes. Foliar spraying of ZnO-NPs gave the most influential results in terms of best planting parameters, namely plant height, early flowering, fruit yields as well as lycopene content. Therefore, more attention should be given to improving quantity and quality as well as nutrient use efficiency of Zn and ZnO-NPs in tomato production. Recent information on the effect of zinc nutrient foliar spraying and ZnO-NPs as a nano fertilizer on tomato productivity is reviewed in this article.

ABSTRACT Currently, tomato is one of the most cultivated crops worldwide, with the highest economic value, increasing its demand and, thus, its expansion, production, and trade. The tomato crop is susceptible to attack of pathogens with devastating consequences on the decline in yields from 50 to 100%. For this reason, new production methods are proposed such as grafting in wild rootstocks, which have high genetic variability and genes responsible for resistance to fungi, bacteria, viruses, and nematodes. The aim of this study was to evaluate the effect of grafting commercial tomato cultivars onto cherry tomato genotypes on yield and fruit quality. The experiment was arranged in a completely randomized design with four replications. The experimental unit consisted of four plants. spaced at 0.9 m between rows (channels), 0.30 m between double rows, and 0.4 m between plants. The treatments consisted of the combination of the following factors: three promising rootstocks (IAC391, IAC426, and LA2076), two commercial scions (Calima and Torrano), two grafting methods (cleft and splice), and two ungrafted commercial controls. Yield components, soluble solids content, percentage of fruit quality, and average fruit weight were evaluated. IAC391 was the most promising rootstock, reaching productions similar to those of the controls. The cleft grafting method, reached a success rate of 98.3%. The commercial scion Torrano stood out for achieving the highest yields.

The agronomic performance and leaf mineral nutrition of the non-melting clingstone peach cv. ‘Catherina’ was evaluated on seven hexaploid plum rootstocks, as well as one Prunus persica seedling. They were assessed over a period of 15 years in a field trial at the Experimental Station of Aula Dei-CSIC (Zaragoza, Spain), located in the Ebro Valley (NE Spain). Growing conditions generated varying levels of tree mortality, the highest with Constantí 1, Monpol and Montizo, whereas all Adesoto, GF 655/2 and PM 105 AD trees survived well. GF 655/2 and P. Soto 67 AD proved to be the most dwarfing rootstocks, while Constantí 1 and Monpol were the most invigorating and generated greater cumulative yields. However, the highest yield efficiency was recorded on GF 655/2 and Montizo, although they did not differ significantly from Adesoto and P. Soto 67 AD. The highest average values for fruit weight were observed on PM 105 AD and the lowest on GF 655/2, but they did not differ significantly from the rest of the rootstocks. The highest average values for the soluble solids content was observed on the Pollizo rootstocks Adesoto and PM 105 AD, followed by P. Soto 67 AD. All rootstocks induced N deficiency, with the exception of Constantí 1, GF 655/2 and Montizo, and iron deficiency, except PM 105 AD. The invigorating rootstock Constantí 1 seems to induce higher SPAD values. According to the ΣDOP index, Montizo presented the most suitable balanced nutritional index, but it did not differ significantly from the rest of the rootstocks except GF 655/2 and P. Soto 67 AD.

A field experiment was conducted to study the effect of foliar application of nutrients on growth, yield and fruit quality of pomegranate (Punica granatum L.) cv. Bhagwa in the experimental farm of the Horticultural Research and Training Station and Krishi Vigyan Kendra Kandaghat, Solan, Dr YS Parmar University of Horticulture and Forestry Nauni, Solan, Himachal Pradesh (India), during the year 2016 - 2017. The experiment was laid out in Randomized Block Design (RBD) with four foliar applications of potassium nitrate, KNO3 (0.5%, 1% and 1.5%); calcium chloride, CaCl2 (0.5%, 1% and 1.5%); boric acid, H3BO3 (0.2%, 0.4% and 0.6%) and their combinations. The first spray was applied one month after fruit set, and the remaining three ones were applied at one month interval. Among the various treatments, significant increase in plant height, plant spread, plant volume, fruit size, fruit weight, fruit yield, total soluble solids, total sugars, reduction in fruit drop and fruit cracking were recorded with the application of KNO3 (1%) + CaCl2 (1%) + H3BO3 (0.4%).  Leaf N, P, K, Ca and Mg were also significantly affected by the foliar application of KNO3 (1%) + CaCl2 (1%) + H3BO3 (0.4%). Therefore, the combined foliar application of KNO3 (1%), CaCl2 (1%) and H3BO3 (0.4%) was found the best treatment for the improvement of growth, yield and fruit quality of pomegranate.
