“…Zucchini plants treated with the following treatments T. viride + K 2 SiO 3 , P. fluorescens + K 2 SiO 3 , T. viride + P. fluorescens + K 2 SiO 3 , E. camaldulensis LE + K 2 SiO 3 , C. sinensis LE+K 2 SiO 3 , and F. benghalensis FE + K 2 SiO 3 showed several phenolic compounds (myricetin, syringic acid, p -coumaric acid, eugenol, vanillin, caffeic acid, 4-hydroxybenzoic acid, pyrogallol, gallic acid, ascorbic acid, ferulic acid, α-tocopherol, salicylic acid, catechol, ellagic acid, and protocatechuic acid) in the methanol extract with different concentrations compared with the control treatment. These phenolic compounds or PDBs are playing the important roles in regulating plant metabolic processes (Boudet, 2007 ; Lin et al, 2016 ; Mosa et al, 2021a ). Simple phenolic acids such as hydroxybenzoic and hydroxycinnamic acids are derived from phenylpropanoid pathway (Mandal et al, 2010 ).…”

There are many technological innovations in the field of agriculture to improve the sustainability of farmed products by reducing the chemicals used. Uses of biostimulants such as plant extracts or microorganisms are a promising process that increases plant growth and the efficient use of available soil resources. To determine the effects of some biostimulants' treatments on the photosynthetic pigments and biochemicals composition of zucchini plants, two experiments were conducted in 2019 and 2020 under greenhouse conditions. In this work, the effects of beneficial microbes (Trichoderma viride and Pseudomonas fluorescens), as well as three extracts from Eucalyptus camaldulensis leaf extract (LE), Citrus sinensis LE, and Ficus benghalensis fruit extract (FE) with potassium silicate (K2SiO3) on productivity and biochemical composition of zucchini fruits, were assessed as biostimulants. The results showed that E. camaldulensis LE (4,000 mg/L) + K2SiO3 (500 mg/L) and T. viride (106 spore/ml) + K2SiO3 (500 mg/L) gave the highest significance yield of zucchini fruits. Furthermore, the total reading response of chlorophylls and carotenoids was significantly affected by biostimulants' treatments. The combination of K2SiO3 with E. camaldulensis LE increased the DPPH scavenging activity and the total phenolic content of zucchini fruits, in both experiments. However, the spraying with K2SiO3 did not observe any effects on the total flavonoid content of zucchini fruits. Several phenolic compounds were identified via high-performance liquid chromatography (HPLC) from the methanol extracts of zucchini fruits such as syringic acid, eugenol, caffeic acid, pyrogallol, gallic acid, ascorbic acid, ferulic acid, α-tocopherol, and ellagic acid. The main elemental content (C and O) analyzed via energy-dispersive X-ray spectroscopy (EDX) of leaves was affected by the application of biostimulants. The success of this work could lead to the development of cheap and easily available safe biostimulants for enhancing the productivity and biochemical of zucchini plants.

“…picual with moringa extract at 0, 2 and 4% increased leaf total chlorophyll content, and fruit set percentage. Besides Mosa et al (2021) mentioned that the foliar application of moringa at 2%, 4% and 6% on seedless grapes. The authors noticed that the application increased leaf chlorophyll, yield and fruit quality rather than control.…”

ZnSO4 on vegetative growth, fruit yield, oil yield and fruit quality of ten-year-old olive (Olea europaea) cv. Kalamata. The trees were planted at a distance of 6 × 5 m in sandy soil under a drip irrigation system. Sixty-five uniform trees of the same growth and size were randomly chosen, arranged in a randomized complete block design (RCBD), and subjected to the same applied agricultural practices in the field during the three seasons. The trees were sprayed three times i.e., at the start of the season (April), at full bloom (mid of May) and three weeks later by the following treatments Control, Moringa Leaf Aqueous (MLAE) at 2000, 4000, and 6000 ppm. The results showed that the foliar application of moringa, zinc and boron solely or in combination improved greatly the leaf chlorophyll content, the number of flowers per m 2 , fruit set % and the leaf content from nitrogen, phosphorous, potassium, zinc and boron and the most obvious effect was noticed with the spraying of combination 3 or combination 2 over control or the rest applied treatments in both experimental seasons. Additionally, it was clear from the shown data that moringa at 6000 or 4000 ppm, and zinc sulfate at 1000 were more effective in improving the same measured parameters over the rest applied treatments in both experimental seasons. The influence of 1000 ppm from zinc or born in olive trees was higher than the effect of 500 or 250 ppm from these elements during study seasons.

“…The samples were air-dried under laboratory conditions and ground using a small laboratory Wiley mill. Approximately 50 g of each of the E. camaldulensis leaves, C. sinensis leaves, and F. benghalensis fruits was extracted with distilled water by the soaking method for 24 h under room temperature [35,56].…”

Background: Natural plant extracts and microbial antagonists have the potential for use in increasing the fungal resistance and productivity of horticulture plants. Methods: The purpose of this study was to evaluate the ability of both natural plant extracts and microbial antagonists as a biotical control of some fungal pathogens, i.e., Fusarium ssp., Exserohilum ssp. and Nigrospora ssp., along with improving the growth and productivity performance of zucchini under greenhouse conditions. Eucalyptus camaldulensis leaf extract (LE), Citrus sinensis LE, Ficus benghalensis fruit extract (FE), and two microbial antagonists Pseudomonas fluorescens (accession no. MW647093) and Trichoderma viride (accession no. MW647090) were tested under in vitro and in vivo conditions. Through morphological characteristics and the internal transcribed spacer (ITS) region, Fusarium solani (accession no. MW947256), F. oxysporum (accession no. MW947254), Exserohilum rostratum (accession no. MW947255), and Nigrospora lacticolonia (accession no. MW947253) were identified. HPLC analysis was used for the identification of phenolic compounds (PCs) and flavonoid compounds (FCs) in the extracts. Results: The highest inhibition percentage of fungal growth (IPFG) against F. oxysporum was obtained with P. fluorescens, T. viride, and E. camaldulensis LE (4000 mg/L); F. solani with P. fluorescens, T. viride, and C. sinensis LE (4000 mg/L); Exserohilum rostratum with P. fluorescens, Ficus benghalensis FE (4000 mg/L) and E. camaldulensis LE (4000 mg/L), and N. lacticolonia with P. fluorescens. Using HPLC analysis, the abundant PCs in E. camaldulensis LE were pyrogallol, and caffeic acid, those in C. sinensis LE were syringic acid and ferulic acid, and those in F. benghalensis FE were gallic acid and syringic acid. In addition, the abundant FCs in E. camaldulensis LE were kaempferol, and naringin, those in C. sinensis LE were hesperidin and quercetin, and those in F. benghalensis FE were kaempferol and quercetin. Under greenhouse experiments, T. viride and E. camaldulensis LE (4000 mg/L) followed by P. fluorescens + T. viride treatments gave the best results of zucchini plants in terms of leaf area, fruits number per plant, yield per plant, and total yield (marketable and non-marketable). Conclusions: Plant extracts and bioagents can be used to control some zucchini fungal pathogens and increase the productivity performance of zucchini plants.
