Effect of Mineral Fertilizers on Productivity and Quality of Winter False Flax

The aim of the research is to study the effect of different backgrounds of mineral nutrition on the yield and quality of oilseeds of winter false flax in different regions of cultivation. The research was conducted in two contrasting regions: the forest-steppe of the Middle Volga region (Penza Research Institute of Agriculture) and the Central steppe zone of Crimea (Crimean Research Institute of Agriculture) in 2018-2020. The object of the research was the winter false flax varietal Baron. In the experiment, the effect of nitrogen fertilizer fertilization on the productivity of winter false flax at a dose of 0 to 60 kg of active substance per hectare with a step of 15 kg has been studied. Ammonium nitrate was used as nitrogen fertilizer. In the experiments of Penza Research Institute of Agriculture, the yield increase with nitrogen fertilizer was 0.07-0.19 t/ha. The highest yield of winter false flax was obtained in the variant with the introduction of nitrogen at a dose of N30, which was 1.61 t/ha, which significantly (0.19 t/ha) exceeded the variant without fertilizers. In the conditions of the Crimea, the yield of winter false flax in the average three years was not high and ranged from 0.95-1.16 t/ha. Fertilizing false flax with nitrogen at a dose of N30 led to an increase in yield by 0.21 t/ha, the productivity of the crop was 1.16 t/ha. Nitrogen fertilizer fertilization led to a slight decrease in the oil content of the seeds. In both regions, the fat content was greatest in the variant without fertilizer and was 39.9 and 40.9 %.

Economic efficiency of oil crops cultivation in the Omsk region

We observed the production of oil crops in the Omsk region in 2016–2020. There are presented data on dynamics of sowing areas under oil crops (sunflower, soybean, oil flax, spring rapeseed, false flax, etc.). Production of oil crops is economically profitable due to sharp rise in sale prices of seeds and decrease in prime cost as a result of lowering of expenses for production. A level of profitability during a research period varied hard depending on expenses for chemicals. The most economically resulting was 2020, yields of oil flax and spring rapeseed was the highest. We studied impact of climatic conditions on yield of oil crops, namely precipitation amount in a period flowering–maturing. Increased interest to oil flax, rapeseed and soybean is conditioned with high economic efficiency of production, good adaptability to the climate of the Western Siberia, high yield and oil content, creating of favorable background for the further crops in rotation. Growth of oil crops production in the Omsk region can be reached both by intensive and extensive components of production. Intensive direction is realized by a range of factors including formation of varietal structure of crops, implementation of an intensive technology including all elements of oil crops cultivation. An extensive way proposes expansion of sowing areas involving fallow lands into sowing structure and northward expansion of early maturing crops cultivation, such as spring turnip rape, false flax and mustard.

Determination of oil content, linolenic and erucic acids contents in false flax seeds using IRspectrometry

Spectroscopy of near infrared reflection (NIRS) was used for estimation of biochemical indicators in seeds of false flax. The purpose of our work was to develop calibrating models for IR-analyzer MATRIXI for determination of weight percentage of oil, linolenic and erucic acids contents in oil of seeds in unbroken seeds of false flax (winter and spring forms). The researches were conducted in the biochemistry laboratory on false flax samples cultivated in 2016–2020 in the different environments of the Russian Federation. Oil content was determined with NMR-analyzer АМV 1006М according to the technique described in the State Standard 8.597-2010, percentage contents of linolenic and erucic acids in oil was estimated on the gas chromatograph “Chromatech – Kristal 5000” with an automatic dipper on a capillary column SolGelWax 30 m × 0.25 mm × 0.5 µcm. The best indicators of quality of the calibrating models (root mean square error of prediction, coefficient of determination, and meaning of a residual deflection of prediction for a rank reflected on a figure) were obtained by oil content (RMSEP = 0.20%, R 2 = 99.3, and RPD = 12.3), linolenic acid content (RMSEP = 0.35%, R 2 = 98.8, and RPD = 9.2) and erucic acid content (RMSEP = 0.14%, R 2 = 85.7, and RPD = 2.6). In a program OPUS LAB, we received a method “False flax 51” based on the developed calibrating models for a routine analysis for determination of oil content, linolenic and erucic acids contents in oil in the unbroken seeds of false flax in an average (9–20 g) in a cuvette with diameter of 51 mm. this method allows conducting express-estimation of false flax seeds for breeding traits with performance of more than 100 sample per seven hours.

Effect of Planting Density on Yield Components of False Flax

This research was carried out to determine the effect of population density on the performance components of false flax (Camelina sativa (L.) Crantz). This would allow to determine the effect of increasing the number of seeds of the false flaxon the yield and also the appropriate sowing distance under Konya conditions. The research was developed in the experimental field of Çumra Vocational School, Konya, Turkey. The experimental design was randomized complete blocks designwith three repetitions. Analyzes were made using the Jump statistics program.A thousand seeds were weighed and 4 different planting population densities were used: 500, 750, 1000 and 1250 seeds per square meter.On May 2, 2014 it was sown and on August 10, 2014 it was harvested. Plant height, number of plants per m2, biomass, root length, number of capsules, number of seeds per capsules, weight of a thousand seeds and other yield values were evaluated. The vegetative period of false flax under Konya ecological conditions was 100 days. The thousand-grain weight was 1.4 g (500) to 2 g (1000), plant height 58.3 cm (500) to 74 cm (750) and root length 9.6 cm (1000) to 16.3 cm (750). The number of capsules per plant and of seeds per capsule ranged from 152.6 (750) to 571.6 (500) and from 11 (1000) to 19.6 (500). In this study, It was found that applications of 1250 seeds per m2 were the most suitable sowing density for yield

The effect of herbicides on winter false flax (Camelina sativa (L.) Crantz.)

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.

Evaluation of Potential Biodiesel Feedstocks: Camelina, Turnip Rape, Oil Radish and Tyfon

Background: One of the most promising alternative biofuels, competitive with regular petrol, diesel or jet fuel is biodiesel, especially derived from plant oils. Until now, various technological approaches, as well as oil sources, have been proposed for biodiesel production, but an industrially scalable technology with high end-product quality and production efficiency has not been developed and brought to the market yet. Biodiesel is produced in Europe and North America mainly from rapeseed, or canola, sunflower and soybean oil. However, other underutilized plant species could also be considered as potential oil feedstocks for biodiesel. The great perspective holds Brassicaceae family, especially such species as false flax (Camelina sativa) and Ethiopian mustard (Brassica carinata), but many other Brassicaceae crops are still out of sight. Objectives: This research has been conducted aiming to identify and compare the productivity of several Brassicaceae crops (camelina or false flax (C. sativa), turnip rape (B. campestris), oil radish (Raphanus sativus var. oleifera) and tyfon (B. rapa ssp. oleifera f. biennis × (ssp. rapifera × ssp. pekinensis)), that are suitable for biodiesel production under conditions of temperate climate regions (Northern America, Europe); and to obtain biodiesel by transesterification of fatty acids present on these species using bioethanol. Methods and Materials: Seed oil content, yield and fatty acid profiles have been studied and analysed in different genotypes of C. sativa (10), winter (6) and spring (4) B. campestris, R. sativus var. oleifera (8) and tyfon (5). The most productive crops have been identified: false flax variety ‘Evro-12’ (1620 kg of oil per hectare) and ‘Peremoha’ (1657 kg/ha); winter turnip rape variety ‘Oriana’ (1373 kg/ha), oil radish variety ‘Kyianochka’ (1445 kg/ha) and tyfon varieties ‘Fitopal’ (1730 kg/ha) and ‘Obriy’ (1860 kg/ha). According to chromatographic analysis results, oils of winter turnip rape and tyfon contain high levels (38-42,8%) of erucic (22:1) acid, while oils from spring turnip rape, false flax and oil radish possess high amounts of short-chained fatty acids (not longer than C18) – up to 85,37% in camelina breeding line FEORZhYaFD. Fatty acid ethyl esters (FAEE) were produced from oil of best genotypes and proved to comply with all main quality requirements for diesel. Results: Moreover, a new solvent-based technology of high-yield (up to 96%) FAEE production, has been firstly proposed for C. sativa oil conversion. Conclusion: Best genotypes that can be used as a plant oil source for biodiesel production have been identified for camelina, turnip rape, oil radish and tyfon species. The data obtained on seed oil content, yield and fatty acid profiles suggested that they are: false flax – breeding form FEORZhYaFD; winter turnip rape - variety ‘Oriana’; oil radish - variety ‘Rayduha’ and tyfon hybrid - variety ‘Fitopal’. Biodiesel samples obtained from these plants fit the Ukrainian standards for diesel fuel and can be used in car engines. The proposed new technological approach to produce fatty acid ethyl esters allows to reduce reaction time and to increase esters yield and quality.

Germplasm material for false flax (Camelina sativa (L.) Crantz.) breeding in the conditions of the Astrakhan region

We studied 25 samples of false flax (Camelina sativa (L.) Crantz.) from the collection of the AllRussian Institute of Plant Genetic Resources (VIR). The study was conducted in the conditions of Astrakhan region in 2016–2017. As a result of the research, we selected 13 samples of false flax with seed yield of 1.0–1.9 t per ha in 2016, 10 samples with yield of 1.0–1.4 t per ha in 2017. The samples possess high biological yield also have the high coefficient of adaptability: 1.03–1.96 in 2016 and 1.1–1.6 in 2017. There was a significant variability in the system of correlations of traits over the years of the research. The correlation structure of variability in 2017 was significantly different from that one in 2016. The number of reliable correlations in 2016 was significantly lower than in 2017. In the factor structure of the economically valuable traits variability in 2016 three factors were identified covering a total of 88.8 % of the variability of the complex of traits. In the factor structure of variation in 2017, three factors were also identified, covering 77.1 % of the variability of the complex. Changes in climatic conditions during the false flax vegetative period effect formation of the main economically valuable traits.

Pests of oil producing cabbage crops in the Eastern Forest-Steppe of Ukraine

Today the major oil producing crops from the Brassicaceae family in the world and Ukraine are winter rape (Brassica napus oleifera bienis D. C.) and spring rape (Brassica napus oleifera annua Metzg.). At present the acreage of these crops in the world is over 40 million hectares, and in Ukraine there are more than 1 million hectares. Less common crops are white mustard (Sinapis alba L.) and Chinese mustard (Brassica juncea Gzem.). The world acreage under the mustard crops is about 3,0 million hectares (in Ukraine there are about 100 thousand hectares). Other oil producing crops from the cabbage family such as spring winter cress (Brassica campestris L.), winter rape (Brassica rapa oleifera DC), winter false flax (Camelina sativa subsp. pilosa N. Zinge), spring false flax (Camelina sativa var. Glabrata (DC.), oily radish (Raphanus sativus L. var. oleiformis Pers) and black mustard (Brassica nigra (L.) Koch) occupy only a small area, while the Abyssinian mustard (Crambe abyssinica Hosts. ex. RE Fr.) is not grown in our country at all. It is impossible to obtain high and stable yields of all agricultural crops without protection of plants from the harmful insects. The losses of the crops due to the pests are huge, especially during the mass reproduction of the insects. The entomocomplex of agroceonoses of oil producing cabbage crops is extremely rich and contains several hundred species. As a result of their vital functions more than 50% of the crops can be lost and as far as 25-55% growth increase in the yield can be reached due to the pollinating insects. Despite the short-term existence of agroceonoses of spring oil producing cabbage crops (90-120 days) their entomofauna is characterised by a considerable diversity of species composition. During the vegetation periods in 2007–2019 in the fields of the Educational, Research and Production Centre “Research Field” of Kharkiv National Agrarian University named after V.V. Dokuchaiev and the State Enterprise “Research Farm “Elitne” of the Institute of Plant Growing named after V.Ya. Yuriev of the National Academy of Agrarian Sciences of Ukraine we have found 54 species of specialised and multi-faceted pests of oil producing cabbage crops that belong to eight lines and 22 families. Among them 29 species are the specialised pests and 25 are multi-faceted ones. The frequency of the pest species occurrence on the crops is the following: eight species (15%) populate the crops on a mass scale, six species (11%) are moderately spread, and 40 species (74%) have a low population density. The cabbage bug, mustard bug, ground cabbage aphid, rose chafer, rape blossom beetle, mesographe flea beetle, flea beetle and diamond black moth belong to the species that populate the crops on a mass scale. Among them four species belong to the Coleoptera line, two species belong to the Hemiptera line, one species belong to the Homoptera line and one species belong to the Lepidoptera line. The representatives of the Coleoptera line dominate; their proportion in the entomological community structure is 48% (26 species). The economic importance of these pests is not the same and greatly depends on the population density and phenophase of the crop development as well as on weather conditions.
