Effectiveness of electron beam irradiation was evaluated against Phytophthora nicotianae var. nicotianae, the causal agent of stem base and root rot of tomato. In laboratory trials, irradiation of 7-day-old Phytophthora cultures growing on potato-dextrose-agar (PDA) medium with 1 kGy resulted in the disintegration of the pathogen’s hyphae. Increasing the irradiation dose to 3 kGy caused decay of the hyphae. Irradiation of infested stonewool with 5 kGy caused decrease of the pathogen population about 5 times. Application of 20 kGy completely eliminated the pathogen from stonewool. Irradiation of substratum resulted in significant increase of tomato seedlings healthiness, especially when the dose 20 kGy was applied.

Arbuscular mycorrhizae are endogenous fungi that form symbiotic association with the vast majority of vascular plants. They help to increase the nutrient uptake, especially phosphorus and to exploit a larger area of soil. Also, they improve soil aggregation, contribute to nutrient cycling processes in plants and improve their tolerance of heavy metal contamination or drought, as well as their susceptibility to root pathogens or herbivores. These fungi colonize the root epidermis and outer cortical layers and release bioactive molecules. The transcriptome and the proteome of plants are substantially altered. They have evolved multiple mechanisms that result in improvements in plant resistance to disease and plant growth and productivity, being included in a lot of combination of biofertilizers. In order to study these mechanisms, gamma irradiation was used to create mutants that are defective in their association. Culture under in vitro conditions is presented as method for maintaining the useful mutants in pure line.

In this study, it was carried out in order to determine the amount of plant nutrients that can be obtained from the wastes of tomato plants grown with soilless agriculture technique in the greenhouse and to make suggestions for evaluation possibilities. For this purpose, cocopeat and plant samples were taken from the soilless greenhouse where tomatoes were grown at the end of production. The stem, leaf, fruit and root of the collected cocopeat and plant samples were separated and N, P, K, analyzes were made in these separated samples. According to the results obtained, the amount of N that can be added to the soil with the cocopeat wastes is determined as 10.58 kg, the amount of P 0.09 kg and the amount of K 0.52 kg for one decare area. The total N amount that can be gained from the roots, stems, leaves and fruits of the waste tomato plant per decare area was determined as 6.65-11.97 kg, P content 1.22-2.52 kg and K amount between 5.10-18.21 kg. Considering the distribution of the amount of NPK that can be added to the soil according to the plant parts. On average, 4.18 kg in root, 2.50 kg in stem, 7.58 kg in leaf and 7.46 kg in fruit were found to be wasted due to not evaluating plant wastes. The organ with the highest N content among plant parts is the leaf, and 42.73% of the total N is found in the leaf. P and K are mostly found in fruits. In addition, 41.73% of P and 36.62% of K are excreted with fruit. It will be possible to improve the soils with insufficient organic matter content throughout Turkey by composting the wastes from greenhouses. In addition, it has been determined that these wastes are very important in terms of reducing the visual pollution caused by these wastes, harmful emissions that will arise as a result of burning and bringing them into the economy.

For several decades an increase of platinum in the environment was recorded. This is connected with the release of platinum from automobile catalytic converters and pharmaceutical industries. In the conducted experiments the effect of various forms and concentrations of platinum on the germination and roots growth of different plants (oat, garden cress and tomato) was investigated. Two separate experiments were performed with lower (experiment 1st: 1, 5 and 10 mg/L) and higher (experiment 2nd: 10, 20 and 40 mg/L) [Pt(NH3)4](NO3)2 or PtCl4 dosages. There was no significant effect of dose and form of platinum on the germination of seeds (experiment 1st and 2nd). The effect of platinum containing substances dose on root growth of young seedlings was observed during experiment, dependent on the species of tested plants. The root length of oat plants was similar in all treatments in experiment 1st. The shortest tomato roots were observed in the case of a 10 mg/L of PtCl4, it was statistically shorter than the control plants (treated with water) as well. The roots of the tomato treated with [Pt(NH3)4](NO3)2 were the same length as observed for the control sample. The garden cress root growth was not affected by [Pt(NH3)4](NO3)2, but a solution containing Pt4+ stimulated the root growth. The roots of tomato and oat treated with [Pt(NH3)4](NO3)2 had similar length as the control plants in contrast to the far shorter roots treated with PtCl4 (experiment 2nd). Moreover, the treatment with [Pt(NH3)4](NO3)2 stimulated the growth of garden cress roots compared to the control, while only the lowest dose of PtCl4 stimulated the root growth.

Water shortage consider on of the main threats facing the agriculture, mainly in the Mediterranean area. So that there is a great need to apply new methods to water resource management. The crop models are used to achieve this objective. Tomato is a significant vegetable crop globally and represent an important part of horticultural production with 180 million tons produced on over five million hectares even though few studies have validated the AquaCrop model, especially in Egypt. This study was conducted in a protected cultivation experimental farm, Agricultural Research Center (ARC), Dokki, Giza, Egypt during the winter seasons of 2019/2020 and 2020/2021. Different irrigation levels (IL): 55%, 70%, 85%, 100%, and 115% of evapotranspiration (Eto) were applied on tomato. Plant growth parameters, relative chlorophyll content (SPAD), yield, fruit quality and plant nutrients (NPK) were recorded at both seasons. Also, the aforementioned irrigation levels were used to validate the AquaCrop model on different climate change scenarios on tomato productivity in 2050 and 2100. The findings revealed that the highest plant growth parameters were obtained in 85% and 100% Eto as compared to all treatments at both seasons. In contrast, the 55% of Eto obtained the lowest values of all plant growth parameters. The number of fruits/plant, early yield, and total yield of 100% Eto were ranked secondly. Fruits quality was significantly affected by the tested ILs. The highest values of TSS, firmness and vit C of tomato fruits were obtained by 55% followed by 70% Eto. The lowest proline content was recorded at 115% of Eto in both seasons. The content of proline in plants of 70% Eto ranked secondly after 55% of Eto in both seasons. The results of AquaCrop model (Version 7.0) revealed that the crop productivity decreased by 4% and 33% of RCP4.5 and RCP8.5 scenarios, respectively, of the years 2050, 14% and 44% for the same scenarios, respectively, of the year 2100.

Olive mill wastewater (effluents from olive oil extraction during harvest) is a source of environmental pollution due to its high acidity and heavy loads of polyphenols and organics. Our aim is to study the phytotoxicity of olive mill wastewater (OMW) at different concentrations on the germination and growth of tomatoes (Solanum lycopersicum L.). To assess this, we measured the percentage of germination (GP), the germination inhibition rate (GIR), the length of the main stem, the number of leaves, and the biomass of the stem, leaves, and roots. The germination test was carried out by placing 25 tomato seeds on filter paper in Petri dishes and then irrigating with different concentrations of OMW (0%, 1%, 2%, 5%, 7%, 10%). The boxes were placed in an incubator at a temperature of 25 °C for 10 days. The results obtained show that, after 10 days of germination, the GP is maximal (more than 98%) at concentrations of less than 7% (r = -0.98; p<0.000) and with an “inhibitory” effect at more than 7% (r = +0.98; p<0.000). However, the growth in length (8.514±2.612 cm) and the number of leaves (4.667±0.866 leaves) were maximum, respectively, at 2% and 1%, after a period of 30 days. However, the dry weight is maximum (0.235±0.049 g) at 5% OMW, however, there is no significant difference in the fresh and dry weights of the stems and leaves for different concentrations. In light of these results, the OMW of crushing units using the continuous three-phase process could be used as an irrigation source at concentrations below 7%, for better tomato yield.

Tomato (Solanum lycopersicum) is an economically important vegetable crop grown in tropical and sub-tropical parts of the world. The objective of this paper is to review nutritional benefits of tomato, its different bioactive components and their application in food products. Tomato and tomato products are very beneficial to our health as they decrease the risk of many diseases, such as cancer, asthma, heart disease etc. The whole fruit of tomato i.e pomace, seed and tomato solids have many nutraceutical benefits and is extensively used in food processing industry either as raw or in powder form. Many bioactive components are present in tomato, such as lycopene, oleoresin, carotenoids etc. Tomato is very popular for high content of antioxidant compounds and antioxidant activity. It is preserved mainly by drying (tray drying, freeze drying) and encapsulation process. We have tried to focus on to get the answer, which one is better in food application, lycopene supplementation or direct tomato powder fortification in food products.

Tomato fusarium wilt is considered as one of the most important diseases of tomato both in field and greenhouse - grown tomatoes worldwide. In presented research, six fungicides; benomyl, carbendazim, prochloraz, fludioxonil, bromuconazole and azoxystrobin, were evaluated for their efficacy against the disease casual agent Fusarium oxysporum f. sp. lycopersici in vitro and in vivo. Seven different concentration (0.0001, 0.001, 0.01, 0.1, 1, 10, 100 μg/ml) were used for assessment of their inhibitory activities against the pathogen through mycelial growth inhibition on potato media. Four concentrations of above mentioned fungicides (0.1, 1. 10 and 100 μg/ml) were tested for controlling Fusarium wilt on tomato plants in glasshouse. Fungal radial growth was measured and median effective concentration (EC50) values (μg/ml) determined. The result of glasshouse tests revealed a different degree of efficacy of all tested fungicides in reducing disease infestation. Prochloraz and bromuconazole were the most effective fungicides against the pathogen both in vitro and in vivo, followed by benomyl and carbendazim. All other fungicides were less effective. Conserning the application date of fungicides it was shown that they were less effective when applied 7 days after tomato plant infection, compared with 1 day prior infection. No phytotoxic symptoms were observed after the application of prochloraz, bromuconazol and benomyl when used at recommended doses, especially on seedlings. However both fungicides fludioxonil and bromuconazole were shown to be phototoxic to tomato seedlings.

Fuzaryjny uwiąd pomidora jest jedną z najgroźniejszych chorób, występujących w uprawach polowych i szklarniowych tej rośliny. Przedstawiono ocenę skuteczności sześciu fungicydów: benomyl, karbendazym, prochloraz, fludioksonil, bromukonazol i azoksystrobin przeciwko czynnikowi sprawczemu choroby Fusarium oxysporum f. sp. lycopersici, w oparciu o wyniki testów przeprowadzonych in vitro i in vivo. Siedem różnych koncentracji fungicydów (0.0001, 0.001, 0.01, 0.1, 1, 10, 100 μg/ml) wykorzystano do oceny stopnia zahamowania wzrostu grzybni patogena na pożywce agarowej, a cztery koncentracje (0.1, 1, 10, 100 μg/ml) testowano na siewkach pomidora w testach szklarniowych. Dokonano pomiaru wzrostu grzybni patogena i określono średnią wartość skutecznej koncentracji preparatów EC50 (μg/ml). Wyniki testów szklarniowych wykazały różny stopień skuteczności ograniczania nasilenia choroby dla wszystkich badanych fungicydów. Fungicydy prochloraz i bromukonazol okazały się najskuteczniejsze w zwalczaniu patogena zarówno w testach in vitro, jak też in vivo, a w dalszej kolejności wymieniono fungicydy benomyl i karbendazym. Pozostałe z badanych preparatów wykazały nieco słabsze działanie. Biorąc pod uwagę terminy stosowania fungicydów należy podkreślić, że były one mniej skuteczne gdy zastosowano je po upływie siedmiu dni od momentu zainfekowania roślin, a najlepszą skuteczność uzyskano w przypadku stosowania preparatów na dzień przed infekcją roślin. Nie obserwowano symptomów fitotoksyczności po zastosowaniu fungicydów: prochloraz, bromukonazol i benomyl, gdy opryskiwano siewki pomidora zgodnie z zalecanymi dawkami preparatów. Wyjątek stanowił fungicyd fludioksonil, który okazał się fitotoksyczny dla siewek pomidora.
