“…An eco-product (EP; named as ''Agriculture Green-tech E", Meydan Solution Ltd, Larnaca, Cyprus) based on rosemary (R. officinalis L. synonym of Salvia rosmarinus L.) and eucalyptus (E. globulus L.) essential oils was used. The main constituents of rosemary oil were 1,8-cineole (32.94%), α-pinene (12.01%), and camphor (20.86%) [32] and eucalyptus oil were 1,8-cineole (74.3%) and α-terpineol (10.3%) [33]. This product was a mixture of these two essential oils (eucalyptus: rosemary in approximately 2:1 v/v ratio) and it also contained vinegar <5% w/w as well as emulsifier-treated water (<80%).…”

“…Leaves were incubated in the dark for 20 min prior to F v /F m measurements. Leaf stomatal conductance was measured on the 4th-5th leaf from the top of the plant (2 measurements per leaf in each plant), by using a ∆T-Porometer AP4 (Delta-T Devices-Cambridge, UK) according to the manufacturer's instructions [32]. All leaves were fully mature and sun-exposed in different individual plants (4 plants/treatment).…”

“…The nutrient content in leaves (four replications per treatment; each replicate consisted of a pool of 2-3 different plant tissue samples) was determined. Leaves were collected, dried at 65 • C for 4 d, weighed, and ground in a Wiley mill to pass through 40 mesh screens as described in Chrysargyris et al [32]. Nitrogen (N) content was determined by the Kjeldahl method (BUCHI, Digest automat K-439 and Distillation Kjelflex K-360, Flawil, Switzerland) [37].…”

The aim of this research was to evaluate the biostimulant effects of an eco-product (EP) containing essential oils of rosemary and eucalyptus on tomato crop. Experiments were conducted to evaluate EP effects on plant growth and physiological parameters (e.g., chlorophyll content), total phenols and antioxidant activity, enzyme activities (e.g., catalase), plant macronutrient content and fresh tomato fruit quality. The application of an EP once (EP-1x) increased tomato plant height by 19%, stomatal conductance, and chlorophyll content compared to the control (sprayed with water). EP triplicate (EP-3x) application significantly increased yield (0.79 kg plant−1) compared to the control (0.58 kg plant−1). However, application of EP-3x was associated with a higher percentage of fruit cracking in comparison to the control. Total phenols and antioxidant activity were affected from both the use of EP and application frequency. EP application decreased by 27.3% the leaf damage index in comparison to the control. Nutrient content in leaves (N, Mg) was significantly decreased in the case of EP-3x treatment. Fruit firmness was decreased by 19.9% in the case of EP-1x application. Fruit marketability and tomato-like aroma, fresh weight and soluble solids did not differ among the treatments. Further research is required to examine the potential use of essential oils as biostimulants.

“…Selection of the most suitable substrate or media has a profound role in the success of hydroponics. Mustard was successfully grown in ferns, coconut husk, burning husk, sawdust, and rockwool media with 3 and 5 h interval water application in and open system; cucumber with different soilless media of tuff, perlite, and sawdust in different proportions was grown in a greenhouse . Quality growth and yield of broccoli, cauliflower, and cabbage were produced using different media like commercial peat and paper waste through pot culture under a plastic greenhouse…”

Soilless culture is emerging as a popular tool to grow agricultural and horticultural crops in open systems, closed systems, protected cultivation, vertical farming, and soil affected or stress-affected areas. The climatic factors and biometabolism are integrated in stimulating quality phenological growth and biochemical and physiological processes in soilless crop production. Soilless crop production (SCP) has immense potential to build a soilless green revolution and for sustaining crop production. Information on substrate and water based culture collected for the period from 1996 to 2022 is reviewed and analyzed in this work. The performance of crops in soilless culture improves morphological and physiological parameters compared with soil based cultivation. The distinct environmental factors positively influence soilless culture to exhibit cellular processes, biological processes, molecular processes, and the ecosystem in the crop. The impacts of ecological factors are more efficient in closed systems compared with open systems. The salient features of metabolites and biometabolism in substrate based media were identified with transcriptome analysis and found to be different compared with soil based cultivation. Developing simple nutrient formulations suited for soilless culture is essential to popularize this technology among marginal farmers.

Effects of Selenium and/or Arbuscular Mycorrhizal Fungal Inoculation on Strawberry Grown in Hydroponic Trial

Strawberry is considered as a fruit of high nutritional value, with appreciated benefits on human health. Arbuscular mycorrhizal fungi (AMF) are commonly used plant symbionts that affect plant growth and its effectiveness is plant species specific. Additionally, selenium (Se) projects a special interest to humans for its antioxidant specialties, and to plants, because of the potential to make them grow faster when added to the nutrient solution. Nonetheless, the performance of arbuscular mycorrhizal fungi (AMF) in Se biofortification in strawberry is unexplored. The purpose of the present study experiment was to determine whether mycorrhizal inoculation of AMF can have a positive impact on growth and quality of strawberries, and whether Se contributes in this effort or will adversely affect the plants. Four Se concentrations (0, 1, 5 and 10 mg L−1) in the nutrient solution, with or without mycorrhizal inoculation of AMF to the root system, were evaluated. Results demonstrated that Se of 10 mg L−1 negatively affected plant growth, photosynthetic rates, decreased fruit firmness and total soluble solids, induced oxidative stress in fruits and affected nutrient accumulation in different plant organs. Mycorrhizal inoculation of AMF mainly stimulated antioxidative mechanisms of the fruits and increased nutrient accumulation for plants grown at high Se levels. Based on our observations, mycorrhizal inoculation can enhance the nutritional value of strawberry fruits and strawberry plants seem to be a strong candidate for Se biofortification, allowing the rise of Se of the consumers’ intake.
