Survey Results

Aim of study: Trait prioritization of potential olive (Olea europaea L.) breeding objectives has been evaluated in this work from two surveys to researchers working on olive and olive producers / orchard managers. Area of study: Olive growing area in Andalusia (South of Spain) Material and methods: Twenty-five breeding objectives were associated to plant growth, fructification, oil content and composition, resistance to pest and disease and tolerance to soil and climatic conditions. Two assessment methods were applied (ranking and rating), showing similar results in both the researchers and producers surveys. Main results: Higher productivity was the objective with the highest score, followed by Verticillium wilt resistance and higher oil content. After them, tolerance to water stress and resistance to Xylella fastidiosa were among the preferred objectives. Conversely, the least preferred objectives were late harvesting, high fruit size and tolerance to water lodging and calcareous soils. In the producers’ survey, results have been consistent among the different types of orchards and farmers’ characteristics. It is also interesting to notice that more than 50% of the producers expressed their willingness to orchard enlargement or renewal in the three coming years and 25% of them would change the olive cultivar. They would be willing to pay an average 43% overprice for new cultivar fulfilling their requirements and 75% would support the use of genetic modified olives. Research highlights: These results should be considered to analyze the scope of current breeding programs and define the main criteria to be considered for future works aiming at developing new olive cultivars.

The purpose of the research was to determine the effect of herbicides on winter false flax and to identify the preparation that does not effect negatively on crop plants. The research was carried out in 20182020 at V.S. Pustovoit All-Russian Research Institute of Oil Crops. The experiment scheme included herbicides with active ingredients (a.i.), which effectively decreased the number of weeds on the plots. The effectiveness of the preparations was more than 70% for different types of weeds. However, the variants with the application of preparations with a.i. clopyralid 300 g/l, S-Metolachlor 960 g/l, ethametsulfuronmethyl 750 g/kg significantly decreased the plant density (by 18-32 pcs/m2) and seed yield (by 0.33-0.52 t/ha) of false flax in comparison with the control. The oil content of seeds was significantly decreased in the variants with the herbicides with a.i. S-Metolachlor 960 g/l with the application rate of 1.6 l/ha and ethametsulfuron-methyl 750 g/kg (by 1.2-1.5 %). In other variants, the oil content of false flax seeds differed from the control insignificantly (by 0.3-0.4 %). It has been established that the preparation with a.i. quinmerac 83 g/l + metazachlor 333 g/l with the application rate of 2.0 or 2.5 l/ha should be applied to decrease the number of weeds in the sowings of winter false flax in the central zone of the Krasnodar region. This preparation, without having a toxic effect, increases the yield by 0.15-0.17 t/ha and does not decrease the plant density and oil content of false flax seeds.

According to the characteristics of oily wastewater, microwave technology was introduced to separate aviation kerosene from oily water. The uniform design with mixed level including main influence factors was applied to design the experimental scheme. The influence factors such as oil content, radiation power, radiation time length and standing time after radiation were considered. The influence of these factors on separation of oil from oily water was investigated through experiments, and deoiling amount formula was regressed. The results show that these four factors are positive to the separation of oily wastewater, of which oil content is the most important to the separation, the product of radiation power and radiation time is the second, and standing time is the third. Treatment of oily wastewater using microwave benefits to the efficiency of discharging sewage and the recovery of oil product to meet the relative standards.

ABSTRACT Basil (Ocimum basilicum L.) is an annual plant that belongs to the Lamiaceae family. It is used as an aromatic and medicinal plant. Basil is grown in different regions with varying climates; the productivity and quality are influenced by both abiotic and biotic factors. This study was aimed to determine the impact of the application of different types of fertilizers on the yield and contents of some bioactive components in basil. The treatments consisted of three different types of fertilizers (mineral, organomineral, and organic) and control (without fertilization). The yield per plant and the essential oil content with fertilizer treatment were better than that in control. The highest fresh yield (450.9 g per plant) and oil content (0.94 mL 100 g-1) were recorded in basil cultivated using mineral fertilizers. Furthermore, the fresh yield (333.9 and 327.8 g per plant) and oil content (0.87 and 0.85 mL 100 g-1) were higher after the application of organic and organomineral fertilizers compared to that in the control treatment. There was no significant effect of fertilizer application on the total phenolics, total flavonoids, and antioxidant capacity. This study demonstrated a suitable practical application of organomineral fertilizers as a nutrient source in basil crop production in areas where the use of mineral and organic fertilizers is limited.

The study focuses on investigating kapok fiber as an adsorbent for oily industrial wastewater. Kapok fiber, KF (Ceiba Pentandra) is a natural plant fiber that poses excellent hydrophobic-oleophilic characteristics, due to the presence of penetrable   hollow   lumen   structure   and   waxy   material on its surface. The objectives of this study are to investigate the morphology of raw and treated kapok fiber (KF) before and after adsorption of wastewater as well as to study the sorption capacity of KF (including raw KF, ethanol-treated KF and chloroform-treated KF) in wastewater. Hence, the morphology of raw KF and KF treated with oil are analysed using scanning electron microscopy (SEM). Besides, the sorption condition of different types of wastewater including emulsified wastewater, immiscible oil-and-liquid wastewater and non-oily wastewater on raw KF are studied in this experiment. From the study, the raw KF shows the best sorption capacity of oil (29.00g/g) compared to the ethanol-treated KF (18.22g/g) and Chloroform-treated KF (16.58g/g) as the treated KF has larger amount of cellulosic content (hydroxyl group) present on the wall of kapok, making it less oleophilic. On the other hand, raw KF has the lowest sorption capacity of water (0.59g/g) followed by ethanol-treated KF (3.05g/g) and chloroform-treated KF (3.20g/g) on non-oily wastewater. Kapok fiber shows great potential as oil sorbent on any type of oil owing to its excellent hydrophobicity-oleophilicity characteristic. In conclusion, the raw KF shows the best sorption capacity of oil compared to the ethanol-treated KF and chloroform-treated KF because the effectiveness is resulted from the hydrophobic waxy coating on the kapok surface. Besides that, the lower sorption capacity of water than oil is due to the incomplete removal of wax from the wall of kapok, making it a little hydrophilic (likes water) as compared to oleophilic (likes oil).

A simulation method was presented based on the theory analysis and ozone reaction equation. The preliminary mathematical models of ozonation correlative to oily pollutant removal were set up by numerical simulation. The ozonation models implied removal ratio of oil related to reaction time, ozone dosage and initial oil content. The simulation results were consistent with the experimental data.
