Abstract:

The paper deals with the effect of pre-winter sowing on earliness and yield of spinach. Sowing was conducted late in the autumn (November-December), i.e. before harsh frosts. Spring sowing served as the control. It was established that pre-winter sowing significantly increased the earliness of spinach and decreased its yield. Due to favorable effect on earliness, pre-winter sowing should be applied in the production of this vegetable. Early spinach is a commodity which is highly requested on the market and is placed on the market at a high price.

Abstract:

The effects of sowing time (autumn and spring) and technique (conventional cultivation, inverted T direct drill, triple disc direct drill and aerial seeding), on the establishment of tall fescue into a weed infested pasture on the Northern Tablelands of New South Wales were examined. A pre-sowing herbicide treatment was included in the 2 direct drilling treatments, and heavy pre-sowing grazing was used in the autumn sowing. The design used 38 plots of 0.12 ha, analysed as 2 separate, complete block experiments, with some common treatments. Tall fescue establishment, 120 days after the autumn sowing, averaged 48 seedlingslm2 on the inverted T treatment (16% establishment). Establishment was improved by 63%, to 78 seedlings/m2, with herbicide and 46%, to 70 seedlings/m2, by heavy grazing. These effects were additive, giving 105 seedlings/m2 for the combined treatments. Only 52 seedlings/m2 established on the triple disc treatment with heavy grazing and herbicide, while establishment on the cultivated seedbed was not different from the inverted T (93 seedlings/m2). There was no establishment after the aerial seeding at either sowing. Fescue establishment showed the same trends in the spring sowing, with 140 seedlings/m2 on the inverted T treatment with pre-sowing herbicide, which was higher than the establishment of 107 seedlings/m2 on the cultivated seedbed. The fescue yield, 18 months after the autumn sowing, was highest in the autumn sown, inverted T treatment with pre-sowing herbicide and heavy grazing (123 kg/ha). In the spring sowing, fescue was recorded only on the cultivated treatment (84 kg/ha) and on the inverted T treatment with pre-sowing herbicide (39 kg/ha). These results show that tall fescue can be re-established into weed dominated pastures on the Northern Tablelands with direct drilling, in either autumn or spring, and that heavy, pre-sowing grazing and herbicide increase fescue establishment.

Abstract:

Not only in the Czech Republic there is a problem with low yield of Douglas fir seedlings in forest tree nurseries. It can be caused mainly by two factors: the type of pre-sowing treatment and the temperature at the time of sowing. The aim of this study is to find out their influence on the emergence rate of Douglas fir. We have tested one specific seed lot originated from the Czech Republic subject to the following variants of pre-sowing treatment: soaking for 48 hours, stratification without a medium for 21 days and for 30 days after 48 hours of soaking and stratification for 30 days with a medium. The treated seeds were sown in a phytotron at temperatures of 13/8 °C – 10/14 hours (day/night) (simulation of early sowing season in February or March) and at temperatures of 17/13 °C – 14/10 hours (simulation of late sowing season in May). In case of the early sowing season, approximately half of the germinable seeds emerged in all treatment variants including the control variant (seeds without stratification). The late sowing season resulted in different emergence rate of the seeds that were subject to different variants of pre-sowing treatment (24–51 %). Then, 21day and 30day stratification were not sufficient for the tested conditions of the early and late sowing season. None of the combinations of pre-sowing treatment and sowing time resulted in full use of the seed potential of the tested seed lot.

Abstract:

The article describes advanced technological processes of pre-sowing of soil and sowing of sugar beet, which positively influences innovative development of beet-growing and scientific-practical project preparation of future specialists in agro-engineering in higher education institutions. In order to increase the field germination of seeds and to ensure the uniform placement of plants in rows, as well as to reduce the cost of growing sugar beets for pre-sowing soil and sowing, a new method is proposed and a device for pre-sowing tillage in the row area is developed. This method ensures that the topsoil is loosened and compacted while sowing the seed only in the row area without loosening it in the row spacing with successively positioned rotating working bodies, planar paws and rolls. According to the results of the researches, an approximate model of the optimal composition of the top soil layer in the aisles and in the row area by its fractional composition and density was developed, the parameters of the working bodies for the pre-sowing tillage were grounded. Initial data were also obtained and initial agrotechnical requirements for the unit for pre-sowing soil and sowing beet seeds were developed. Application of technological process with optimally grounded parameters of strip pre-sowing tillage in the area of rows and sowing of seeds in one pass of the unit and technical means for its execution gives the opportunity to qualitatively prepare the soil with formation of the most favorable fractional composition for seed germination. This increases the field germination of seeds and the uniform distribution of plants in rows, reducing the cost of fuel and direct operating costs of growing sugar beets. The results of the research can be used to improve and optimize zonal technologies and facilities for growing sugar beets, as well as in the educational process and scientific activities of students.

Abstract:

The use of electrophysical influences for pre-sowing treatment of seeds is an effective way to increase their sowing quality. The use of these methods is limited by the fact that their implementation requires new technological equipment in grain processing lines. This problem is solved more easily when pre-sowing processing is performed using installations for active ventilation and grain drying. (Research purpose) The research purpose is in determining the possibility of using active ventilation units and ultra-high-frequency convective grain dryers for pre-sowing grain processing and to evaluating the effectiveness of such processing using computer modeling. (Materials and methods) It is necessary to ensure the uniformity of processing with external influence the seeds placed in a dense layer. Authors carried out pre-sowing treatment of seeds on real installations. Treated seeds were sown in experimental plots and the results of treatment were evaluated. (Results and discussion) The article presents graphs of changes in grain temperature and humidity during processing. To check the feasibility of pre-sowing treatment, authors performed modeling of air-heat and ultra-high-frequency convective seed treatment processes. Based on the results of field experiments, air-heat treatment stimulates the development of secondary plant roots, contributes to an intensive increase in the green mass of plants; ultra-high-frequency convective seed treatment allows increasing the number of productive stems in plants, the number of ears in one plant. (Conclusions) Technological equipment designed for drying and active ventilation of grain can be effectively used for pre-sowing seed processing. In the course of field experiments, it was revealed the possibility of controlling the structure of the crop using different types of external influence on seeds during their pre-sowing processing.

The studies results influence of the growth regulator Vermiyodis and sowing norms on wintering of winter oilseed rape plants and Mercedes hybrid on sod podzolic soils of the experimental field of Prykarpattia of the State Agricultural Experimental Station of the NASG region are presented. Studies have shown that the variants with the pre-sowing treatment off the winter variety Cheremosh seeds was carried out, on average over the years of research, at the sowing rate of 0600000 / ha plant death during overwintering was 4.7-5.7 pcs / m2 or 9, 5-10 , 8%, at a sowing rate of 0800000 / ha of germinating seeds - 5.7- 6.2 pieces / m2 or 8.5-9.3%, at a sowing rate of 1.0 million / ha of similar seeds - 8.7-9 , 3 pcs / m2 or 10.1- 10.9%. In the variants where the pre-sowing treatment of seeds was carried out with the Vermiyodis regulator at a dose of 5 l / t at a sowing rate of 08mln / ha, the plant death was 4.6-5.6%, which is 2.8-3.0% less than the norm sowing 1.0 million / ha of germinating seeds. In the variants where the pre-sowing treatment of seeds of the winter hybrid Mercedes was carried out with the growth regulator "Vermiodis" 5 l / t, the percentage of dead plants was 4.8-5.6% at the sowing rate of 0600000 / ha of germinating seeds, at the sowing rate of 0.8 million / ha - 6.1-7.3%, with a sowing rate of 1.0 million / ha of germinating seeds 8.1-8.6%, which is significantly less than the control and options, where presowing seed treatment was carried out with the growth regulator "Vermijodis". Studies have shown that the best overwintering, on average over the years of research, was in the rapeseed variety of winter hybrid Mercedes at a sowing rate of 0600000 / ha of germinating seeds, in the variety Cheremosh at a sowing rate of 0800000 / ha of germinating seeds for pre-sowing seed treatment.

Abstract:

The influence of pre-sowing treatments using hydropriming, osmopriming and halopriming in laboratory and/or nursery tests on seedling emergence, seedling weight and plant growth of endive and chicory was examined. Halopriming (KNO3) or growth regulators (gibberelic acid; GA3) improved the rate of germination of endive and chicory and reduced the mean germination time needed. 30 min pre-sowing treatment with NaHClO3, methyl jasmonate and dictamus essential oil decreased seed germination as well as seed radicle length in vitro. In the nursery tests, pre-sowing treatments had in some extent impact on the upper part (fresh weight) of the seedling, while no major changes were observed for leaf number and root fresh weight. 6-benzylaminopurine (BAP) or NaHClO3 treatment reduced plant growth of both species. The present study suggests that KNO3 and secondly GA3 treatments may improve rapid and uniform seedling emergence and plant development in nurseries and/or in greenhouses, which is easily applicable by nursery workers with economic profits.

Abstract:

The residual phytotoxicity of 2,4-D mine and dicamba to sorghum (Sorghum bicolor L.) and sunflowers (Helianthus annuus L.) was investigated under central Queensland conditions of variable rainfall and high temperatures. Effects of soil water content, sowing depth, and leaching in clay soils were determined. Phytotoxicity, as measured by decreases in shoot dry matter in pots, increased with herbicide rate and decreased rapidly in moist soil (34% w/w) but was maintained for at least 14 days in dry soil (114% w/w). 2,4-D and dicamba were phytotoxic when leached into the soil but not when they remained on the soil surface. Seedling growth and yield were not affected by 2 kg 2,4-Dha applied at 7 or more days pre-sowing, or by 0.5 kg 2,4-D/ha and 0.14 kg dicamba/ha applied at 1 day pre-sowing, in 5 field environments. When either herbicide was applied at higher rates 1 day pre-sowing, seedling growth was reduced if 25 mm of irrigation was received within 4 days of sowing, and yields were reduced in the field environment that received 144 mm of rainfall within 14 days of sowing.

Abstract:

The studies found that the most promising is the autumn sowing with pre stratification within 30 days. This provides greater germination energy and output of seedlings for 1 ha and plants have maximum increase in height. In the average 3-year greatest output of standard seedlings compared with the control was in the autumn sowing after 30 days of pre-stratification of seeds and it was 377, 7 thousand units from 1 ha. Also, studies have shown that in the autumn seeds sowing output of standard seedlings is in 1.5…1.7 times higher than during the spring sowing. Obtained materials were processed statistically, which increases their reliability.

Abstract:

The aim of this study was to improve understanding of (1) the effect of genotypic and environmental factors on pre-anthesis development and leaf appearance traits of barley and wheat; (2) the relationship of these factors with grain yield, and (3) the differences between these two crops across different environments/sowing dates. Therefore, trials with six two-row winter barley and six winter wheat cultivars were carried out in two successive growing seasons on four sowing dates. Our study showed that the observed traits varied between species, cultivars and sowing dates. In both growing seasons, biomass at anthesis and grain yield declined almost linearly by delaying the sowing date. There was no clear advantage in grain yield of wheat over barley under conditions of later sowing dates. Generally, barley produced more leaf and had shorter phyllochron than wheat. Both wheat and barley showed a similar relationship between grain yield and different pre-anthesis traits.

Abstract:

Sunflower cultivation is relevant in the climatic conditions of Western Kazakhstan, characterized by high heat supply and a long growing season. In order to obtain a high yield of sunflower in the system of adaptive technologies, proper pre-sowing preparation of the soil and optimal sowing times are important. Weeds cause great damage to the sunflower crop. Having a powerful underground and aboveground mass, sunflower competes with weeds better than many other field crops. As the accounting data showed, in our studies of 2018-2020, the greatest contamination of sunflower crops was in the variants without the use of herbicides. So, on average for 3 years in the phase 2 of real leaves, when using the harrowing + pre-sowing cultivation (control) technology, there were 10.67 weeds per 1 m2 with a raw mass of 31.22 g/m2. According to research data, on average for 2018-2020, the highest oil harvest is set for the harrowing + pre-sowing cultivation option with roundup (2 l/ha) – 9.57 с/ha. When using 1 and 2 inter-row treatments combined with harrowing and pre-sowing cultivation, the oil harvest increased to 7.16-7.95 с/ha, which is more than the control by 0.92-1.71 с/ha.

Abstract:

The best variant of the experiment is the application of lime (1 norm per year), mineral fertilizers with pre-sowing treatment of seeds with rhizotorphin and microfertilizer Vuxal Extra CoMo, foliar fertilization in the budding phase with microfertilizer Vuxal Microplant during vegetative growth and Vuxal budding, which provided the density of standing in vegetable varieties Skinado and Somerwood at 1179.8 and 1183.1 thousand / ha. This is higher than the control by 91.3 and 90.8 thousand / ha. Field germination of seeds was higher in the variant, where against the background of mineral fertilizers carried out pre-sowing treatment of seeds with rhizotorphin and microfertilizer Vuxal Extra CoMo with the introduction of lime (1 norm per year) field germination was in vegetable varieties Skinado and Somerwood - 91.8 %, which is higher than in the control by 3.9 and 3.6%, respectively. The shortest duration of the period of germination-beginning of technical maturity was observed in the variants of the experiment, where against the background of mineral fertilizers N30P60K60, pre-sowing treatment of seeds with rhizotorphin was carried out and in pea varieties Skinado - 54 days and Somerwood - 57 days. Carrying out pre-sowing treatment of seeds with Vuxal Extra CoMo microfertilizer against the background of mineral fertilizer N30P60K60 and pre-sowing treatment of seeds with rhizotorphin led to prolongation of the period of germination-beginning of technical ripeness in Skinado pea varieties up to 55 days and 58 Somerwood. A longer period of seedlings-beginning of technical maturity was observed in the variants of the experiment, where mineral fertilizers, pre-sowing treatment of seeds with rhizotorphin and microfertilizer Vuxal Extra CoMo, foliar fertilization with microfertilizers Vuxal Microplant during vegetative growth, Wuxal and Skinado pea varieties - 58 days and Somerwood - 61 days.

Abstract:

Successful production of healthy seedlings in a forest nursery can be ensured through seed treatment to enhance germination. This study assessed the effects of pre-sowing treatments on the germination of Jatropha curcas; to provide the best treatment for enhancing seedling production. The experiment was laid in a completely randomized design with four treatments: (i) control (T1), (ii) soaking in; water at room temperature at room temperature for 16 hours (iii) cow-dung slurry for 16 hours (iv) 98% concentrated sulphuric acid for 5 minutes Each treatment received 10 seeds and was replicated 5 times giving a total of 200 seeds sown in sterilized river bank sand. Germinated seeds were counted, converted to percentages and arsine values. The data were further subjected to analysis of variance and significant means were separated using Duncan multiple range test (DMRT) at 0.05 level of significance. The results showed that seeds with no pre-sowing treatment had the highest mean germination (66%), DMRT revealed that significant difference (P<0.05) existed between seeds with no pre-sowing treatment and other treatments. The study concluded that viable Jatropha curcas seeds have no germination problem; the seeds could be germinated without pre-sowing treatment.

Abstract:

Three seedbed preparation methods were compared from 1977 to 1989 to evaluate their effects on crop production. Treatments were conventional cultivation (CC, at least 3 workings pre-sowing), reduced cultivation (RC, 1 cultivation plus knockdown herbicide pre-sowing), and direct drilling (DD, no pre- sowing cultivation, knockdown herbicide only). Wheat (Triticum aestivum) was sown for the first 8 years of the experiment and lupins in 1985 and 1988. In 9 of the 11 years wheat grain yield was significantly better with DD, averaging 15% more than CC and 10% more than RC. Weed populations were generally greater where cultivation occurred; particularly fumitory (Fumaria spp.) and eyespot lodging (Tapesia yallundae) had greater impact on wheat in the CC and RC treatments.

Abstract:

The paper shows the effect of fungicide seed pre-treatment on the productivity and infestibility of spring barley root rot which is seen as the most common and harmful disease in the Kurgan region. The authors highlight the hydrothermal conditions were favorable for spring barley cultivation within the experimental period. The hydrothermal coefficient of summer months of the vegetation period in 2017 was 1.03; 2018 - 0.89, and in 2019 - 0.95. The researchers found out that the disease progress index depended on hydrothermal conditions of the vegetation period, and was reduced by means of favorable regime of moisture, root rot development. The regression equation is as follows: y = 108.7-90.9x. The researchers observed lower disease progress, with the most effective root rot suppressed by Scarlet and Polaris specimens (the disease progress index decreased to 9.6-13.1%). At pre-sowing treatment of seeds there was The impact of seedbed preparation on the disease progress index was 37.4%. When treating seeds with specimens, spring barley yield increased by 9.3-17.3%. Spring barley productivity increased under favorable hydrothermal conditions, the effect of this factor was 23,8%, and the effect of pre-sowing treatment of seeds was 55,5%. During the research period the spring barley yield decreased while root rot infestation increased; the regression equation is as follows: y = 28.36 - 0.49x. To reduce the infestation of root rot and increase the productivity of spring barley, the paper suggests to apply pre-sowing disinfection of seeds with specimens Scarlet (rate of consumption of 0.4 l/t) and Polaris (rate of consumption of 1.5 l/t), while the disease progress rate reduced and yield increases by 13.2-17.3%.

Abstract:

The research is devoted to the study of the behavior of the generalizing magnetization vector in the seeds of agricultural crops under the action of longitudinal constant and transverse alternating magnetic fields by the method of nuclear magnetic resonance. Based on the theoretical studies, the value of the average magnetic susceptibility per unit volume of seed χ and the value of the magnetization vector were determined. For the system of microparticles of cells of plant origin, the average magnetic susceptibility per unit volume of seed is χ = 2.1 · 10-5, and the magnetization vector M=13.125 mA/m at a longitudinal constant magnetic field strength H = 625 A/m. When a weak transverse alternating magnetic field is superimposed on the frequency, the oscillation frequencies of the magnetization vectors M coincide with the field frequency, which is a condition for the occurrence of magnetic resonance. The longitudinal magnetization vector during the transition from the ground state to the excited state (resonant) describes a trajectory in the form of a spiral on the surface of the sphere. A mathematical model for a biological system taking into account the Earth's magnetic field is built. It is established that for the technology of pre-sowing treatment of seeds of agricultural crops, the inductor, which creates a constant magnetic field, must be located so that the vector of the constant magnetic field of the inductor coincides with the vector of the Earth's magnetic field. Keywords: bioenergetic resonance, pre-sowing treatment of crop seeds, direct magnetic field, alternating magnetic field, longitudinal and transverse relaxation

Abstract:

Ensuring an increase in crop yields and a reduction in plant morbidity without the use of chemicals is an important task. Currently, many researchers have found a positive effect of a constant magnetic field on crop seeds during pre-sowing treatment, which is manifested in increasing crop yields, reducing plant morbidity, improving biochemical parameters and product quality. The aim of the study was to establish the influence of the magnetic field on the sowing qualities of oat seeds during pre-sowing treatment. Experimental studies of the effect of the magnetic field on the germination energy and seed germination were performed with oat seeds of the Desnyansky variety by the experimental planning method. It has been established that the rate of chemical reactions, ion transport, membrane permeability, seed water absorption and oxygen concentration in cells increase during seed treatment in a magnetic field, which contributes to the improvement of seed sowing qualities. It is established that the change of sowing qualities of seeds during their treatment in a magnetic field depends on the square of magnetic induction, the magnetic field gradient and the seed velocity. The most effective mode of pre-sowing treatment of oat seeds in a magnetic field is a magnetic induction of 0,065 T with fourfold re-magnetization, a magnetic field gradient of 0,57 T/m and a velocity of 0,4 m/s.

Abstract:

In this study, we conducted an experiment to evaluate the effect of pre-sowing seed treatment with 0.05% KCl to the yield and quality of two peanut cultivars L14 and L23 grown in Bac Ninh province, Vietnam. After careful selection, the seeds of L14 and L23 were divided into two parts. Part 1 (control) was treated with distilled water and Part 2 (experiment) was treated with 0.05% KCl. The field experiment was arranged in a Split-plot design with four replications. The results show that pre-sowing seed treatment with 0.05% KCl increased the yield components (weight of 100 pods, weight of 100 seeds, mass ratio of unshelled peanuts, number of pods per plant) and yield of both L14 and L23 when compared to the control, in which the yield of L14 is higher than that of L23. Pre-sowing seed treatment with 0.05% KCl also increased the quality of peanuts such as starch content, reducing sugar, lipid, saponification value, protein, B vitamins, total amino acids and content of some mineral elements in peanuts such as N, K, Ca, Mg. The results of this study demonstrate the importance of pre-sowing seed treatment for peanuts.

Abstract:

The importance of studying pre-sowing seed treatment lies in the possibility of regulating the rate of seed germination, the intensity of their growth and obtaining root exudates in biotechnology. The effect of three pre-sowing treatment methods was examined (control – washing with running water; the first method – washing with 0.05% sodium permanganate solution; the second method – 30 seconds in 70% ethyl alcohol (C2H5OH) and 30 minutes in 5% sodium hypochlorite (NaOCl); the third method – 5 minutes in 70% C2H5OH and 40 minutes in 5% NaOCl) on the growth rate, germination rate, excretion rate of seeds of wheat and peas and composition (of protein, carbohydrate, amino acid content) of root exudates from the first to the third day of growth in order to obtain root exudates. It was revealed that the same pre-sowing treatment of wheat and pea seeds has a different effect on the rate and variability of seedling growth from the first to the third day, as well as on the qualitative and quantitative composition of root exudates. It was shown that pre-sowing treatment of wheat and pea seeds for 5 minutes with 70% ethanol followed by treatment with sodium hypochlorite (a “hard” treatment method) accelerates seedling growth and seed germination. This method of treatment reduces the intensity of excretion of root exudates and composition in wheat, but it increases the intensity of excretion in peas. The discovered effects can be explained by hormesis. Additionally, the third method of pre-sowing seed treatment can be used in root technologies for obtaining root exudates.

Abstract:

Pre-sowing treatment of seeds in a magnetic field can increase crop yields, reduce the incidence of plants and improve product quality.Research purposeTo analyze the mechanism of the magnetic field influence on seeds, determine the most effective mode of pre-sowing treatment of leguminous crop seeds in a magnetic field and design parameters of the equipment.Materials and methodsThe authors have determined that under the influence of a magnetic field, the rate of chemical and biochemical reactions in plant cells increases, the transport of ions and molecules through the cell membrane increases, and the membrane permeability increases, so the sowing qualities of seeds improve and their yield increases. Experimental studies were carried out with seeds of "Adagumsky" peas variety and "Gribovsky" beans variety, using the experiment planning method. Magnetic induction and the velocity of seed movement in a magnetic field were taken as influencing factors.Results and discussionWith a change in the magnetic induction from 0 to 0.065 T, the germination energy, germination, biometric indicators, and the yield of peas and beans increase, while with further increase in magnetic induction they decrease. It has been revealed that the use of four-time magnetization reversal enhances the effect of magnetic seed treatment. The velocity of seeds is a less significant factor than magnetic induction. The most effective treatment mode occurred at an energy dose of 1.90 J·s/kg for peas and 1.86 J·s/kg for beans, which is provided for a pole division of 0.23 metre. The authors have designed a plant for pre-sowing treatment of seeds in a magnetic field, which consists of four pairs of magnets installed in parallel above and below the conveyor belt with variable polarity.ConclusionThe most effective pre-sowing treatment of leguminous crop seeds in a magnetic field is a magnetic induction of 0.065 T with fourfold reversal and a conveyer movement speed of 0.4 metre per seconds, which provides an increase in peas yield by 42 percent, and that of beans – by 23 percent.

Abstract:

This study addresses the need to find preemergence herbicides for the direct sowing of seeds of forest species dedicated to the establishment of energy plantations. Twelve different preemergence herbicides were evaluated on the direct sowing of two forest species with great potential for biomass production for bioenergy. One of the limiting aspects of the plantations energy is the high cost of establishment by concept of acquisition of plants, so we looked for the best options for direct sowing of pregerminated seeds of Gmelina arborea (Melina) and Gliricidia sepium (Black Madero), and offer an alternative in lowering costs. The experiment was carried out in a greenhouse (ITCR, Cartago), for 10 weeks, analyzing each species separately. A randomized complete block experimental design was used. The seeds were subjected to the best pre germination treatment and sown in pots, they were immediately atomized by the different pre-emergent herbicides following the protocol described in the methodology. At the end of the experiment it was determined that pre-emergent herbicides with the active ingredient of Linuron and Oxyfluorfen can be used in the direct sowing of Melina, as they did not cause damage to plant yields, in addition to obtaining most of the parameters with statistically superior results. In the case of black Madero the pre-emergent Linuron obtained the best results, concluding that it can be useful for use in direct sowing. The pre-emergent herbicide with the active ingredient of Pendimethalin obtained the lowest yield results in almost all the parameters analyzed; For both species it produced the total death of the weeds before week 7.

Abstract:

In modern conditions, to increase the yield of cultivated plants use pre-sowing seeds with the use of chemical and biological products. Due to the orientation of the world's leading countries on environmentally friendly agricultural production technologies, more and more attention is being paid to the development of electro-technological processing methods. The main advantage of electromagnetic technology for pre-sowing seed treatment with low-energy radiation of the EHF range is the possibility of improving their growth and development by mobilizing the internal reserves of the seed itself, accelerating the diffusion of molecules through the cell membrane, the speed of chemical reactions and causing redness plants and promotes yield without chemical or biological agents or genetic engineering methods. The technology of seed treatment EMF EHF allows to store in the seed all the nutrients, vitamins and minerals, which when processed by other methods is difficult to achieve. The study is based on the analysis of literature, theoretical and experimental studies of the energy and spectral characteristics of the diode generator in the EHF wavelength range, which can be concluded that the increase in plant yields is possible based on the use of millimeter-wave electromagnetic radiation for pre-sowing seed treatment. The article proposes a technique for investigating the energy characteristics of a semiconductor six-diode generator on avalanche-spanning diodes for pre-sowing seed treatment of cultivated plants. The result of the developed technique is that one of the main elements of the plant for pre-sowing seed treatment is the emitter of EM energy, which should form the necessary radiation pattern and provide a sufficient level of power flow density on the grain.

The article presents the results of scientific research on the growth-stimulating preparations in the pre-sowing treatment of soybean seeds and crops according to the development phases in the foreststeppe zone of the Middle Volga. It contains the results of the 2016-2018 research with an assessment of indicators of plant safety, photosynthetic activity and soybean yield in different treatment options by growth factors. The two-component preparations in pre-sowing seed treatment contribute to better soybean germination up to 78.12%. The pre-sowing treatment of seeds with Risotorphine and Raykat Start preparations forms the maximum leaf area. Comparing three years, we can say that the leaves work more productively in the variants with the use of Risotorphine and Raykat Start in pre-sowing treatment. Weather conditions in 2018 allowed soybean crops to form a high yield. The yield level was in the range of 1.48 - 1.98 t / ha. Inoculation of seeds with Raykat Start followed by crops treatment in the phase of 3-5 leaves and budding allowed achieving maximum yield for all years of research. After treating the seeds with Raykat Start, the maximum grain yield was 1.40 t/ha with a double-treatment of crops by microfertilizing mixture Megamix Profi in a phase of 3-5 leaves and budding.

This study aimed to analyze the seasonal dynamics of sugar beet leaf and root yield and quality in different plant populations and the nitrogen fertilization rate. The field trials were set as four different planting densities (60,000 to 140,000 plants ha−1) and three different spring nitrogen fertilization rates: no fertilization, pre-sowing (45 kg ha−1 N), and pre-sowing with top dressing (99 kg ha−1 N in 2014 and 85.5 kg ha−1 N in 2015. The changes of leaf growth were done measuring leaf area (LA), leaf area index (LAI), specific leaf area (SLA), and leaf area ratio (LAR). The highest LAI in 2014 was determined on 30 July at 140,000 plants ha−1 (9.35 m2 m−1) and in 2015 on 20 June at 100,000 plants ha−1 (4.83 m2 m−2). In both years, the SLA and LAR was highest at the end of May. In relation to plant density, higher plant densities had on average the highest root yield, sucrose content, and white sugar yield. In both years, pre-sowing with top dressing spring nitrogen fertilization resulted in the highest root (95.0 t ha−1) and white sugar yield (11.4 t ha−1), whereas the highest sucrose content was after pre-sowing fertilization (14.9%).

The article provides the results of three year (2017-2019) study of the effect of pre-sowing treatment of seeds and foliar fertilizing on productivity and seed qualities of winter triticale varieties (×Triticosecale Wittmack.) Izhevskaya 2 and Zimogor. The research was carried out in the conditions of the Udmurt Republic. Pre-sowing seed treatment was done with fungicide Vial TT, compound fertilizer Agree’s Forsazh and plant growth stimulant Mival-Agro in their pure form, with tank mixtures containing Vial TT fungicide, and with mineral fertilizer Emix. Foliar feeding with Agree’s Nitrogen Potassi-um compound fertilizer was done once during the phase of spring tillering and twice - during the phases of spring tillering and full heading. Pre-sowing seed treatment combined with foliar fertilizing provided an increase in yield productivity of Izhevskaya 2 variety seeds by 0.07-0.55 t/ha (or 3-24 %), of Zimogor variety – up to 0.27 t/ha (or up to 11 %). The techno-logical practices promoted the increase in the laboratory germination of seeds by varieties – 1-2 % (control 91 %) and 2-3 % (control 88 %), respectively, germinative power – 2-4 and 1-2 % (control 93 %), respectively, degree of seedling development in both varieties – by 0.1-0.3 points (control – 4.5 and 3.7 points). The highest productivity of Izhevskaya 2 variety seeds (2.85 t/ha for 3 years on the average) has been obtained by pre-sowing treatment of seeds with Agree’s Forsazh and foliar fertilizing during the phase of spring tillering that is higher than in the control variant by 0.55t/ha (or 24 %). The increase in yield productivity of winter triticale Zimigor seeds up to 2.81 % (addition to the control is 0.24t/ha or 11 %) was promoted by pre-sowing treatment of seeds with Agree’s Forsazh regardless of multiplicity of foliar fertilizing. The seeds obtained were characterized by high sowing qualities of seeds: the germinating energy of Izhevskaya 2 variety seeds was 85 %, of Zimogor variety – 82 %, the laboratory germination – 93 % and 92 % , respectively, the germinative power – 97 % and 94-95 %. Double foliar fertilizing with Agree’s Nitrogen Potassium combined with pre-sowing treatment with Vial TT, Mival-Agro and their tank mixtures showed high effectiveness in Zimogor variety. Seed productivity in both of these variants was at the same level (2.73 t/ha). The above-mentioned practices can be successfully used when producing winter triticale seeds.

Abstract:

The results of the influence of pre-sowing seed treatment, the main application of mineral fertilizers and foliar fertilizing with ammonium nitrate, urea, organo-mineral fertilizer D2 or bacterial preparation Escort-bio on the formation of productivity and quality of spring wheat of the Elegia mironovskaya variety are presented. Experimental investigations were carried out on the Chernozem of the South during 2014-2016. In the conditions of the educational, scientific and practical center of the Nikolaev NAU. The results of research showed that the introduction of nitrogen-phosphorus fertilizers before sowing and foliar fertilizing of spring wheat crops on average over three years provided an increase in grain yield by 1.00–1.58 t/ha in variants with water treatment of seeds and by 1.08–1.72 t/ha when processing seeds with microbial preparation Escort-bio. Pre-sowing treatment of escort-bio seeds contributed to the additional production of 0.14–0.28 t /ha of grain, depending on the fertilizer option. The highest grain yield was formed by applying N30P30 for pre-sowing cultivation, treating seeds with a microbial preparation and carrying out the phase of plant exit into the tube of feeding with ammonium nitrate with a dose of N30. Pre-sowing treatment of escort-bio seeds and foliar fertilizing contributed to an increase in the payback of fertilizers by increasing the yield of spring wheat. The maximum specified indicator is determined by the background of bacterial seed treatment, the main application to the sowing of N30P30 and carrying out two top-UPS with organo-mineral fertilizer D2 or Escort-bio. Application of fertilizers and foliar top-UPS on average over three years increased the protein content of spring wheat by 0.7–1.4 %, and gluten – by 1.2–1.9 %. The maximum both indicators of grain quality are determined in the version of the main application of N30P30 with making-up at the beginning of the earing phase with urea at a dose of N30 –14.9 and 28.1 %. The conditional yield of protein and gluten from a hectare of spring wheat sowing with an improvement in the background of plant nutrition grew and reached maximum values in the variants of N60P30 before sowing or N30P30 before sowing with fertilizing with ammonium nitrate at a dose of N30 in the phase of exit to the tube.

Abstract:

In the southern zone of Kazakhstan, agricultural crops are cultivated, both on irrigated and rain-fed lands. The main technology used for tillage is traditional, which accounts for 90% of all cultivated crops. This technology provides for multiple passes of machine-tractor units (MTU) across the field, which causes a large load on the soil, leading to the destruction of its structure. In the South of the Republic, combined tools supplied from neighboring countries (Russia, Belarus, Ukraine) are mainly used for pre-sowing tillage. They do not correspond to the soil and climate conditions and technologies used. To ensure the required quality of soil preparation, it is necessary to use machines adapted to zonal conditions. To develop a combined tool for pre-sowing and basic tillage, the parameters of its working bodies were justified. Based on the conducted research, a prototype of the combined OKP-4,0 machine was manufactured at the experimental plant of "SPC of agricultural engineering " LLP, and its acceptance tests were carried out during the operation of pre-sowing soil preparation for corn sowing, according to which the quality of soil treatment corresponded to agricultural requirements. There were no breakdowns or failures in operation.

The highest indicators of plant height of vegetable pea varieties were observed in the variants of the experiment, where mineral fertilizers, pre-sowing treatment of seeds with rhizotorphin and microfertilizer Vuxal Extra CoMo, foliar fertilization with microfertilizers Vuxal Microplant during vegetative growth and Wuxal Caucasus vegetable Skinado − 84.2 cm and Somerwood − 84.3 cm. However, the greater influence on the formation of plant height was provided by pre-sowing treatment of seeds with microfertilizer Vuxal Extra CoMo against the background of mineral fertilizers N30P60K60, and pre-sowing treatment of seeds with rhizotorphin and was higher in pea varieties Skinado and Somerwood by 3.2 and 3.8 cm compared to control . The largest number of seeds per plant was obtained in the variant of the experiment, which was applied foliar fertilization with microfertilizers Vuxal Microplant during vegetative growth and Vuxal Calcium, Boron during budding on the background of mineral fertilizers N30P60K60, and pre-sowing treatment of seeds with rhizotorph Skinado pea varieties − 67.41 and Somerwood − 72.48 pieces, which is 19.77 and 21.56 pieces. more than the control. The use of liming (0.5 and 1.0 norms per g. K.) Led to a moderate increase in the number of seeds per plant. The best option provided the highest number of seeds on the plant, where liming was carried out (1.0 norm per hectare) on the background of mineral fertilizers N30P60K60 and pre-sowing treatment of seeds with rhizotorphin and microfertilizer Vuxal Extra CoMo and applied foliar fertilization with microfertilizers Vuxal Micro time of growth of vegetative mass and Vuxal Calcium, Boron during budding in varieties Skinado − 67.94 and Somerwood − 73.59 pieces, which is higher than in the control by 20.3 and 22.67 pieces, respectively. Key words: peas, liming, fertilizers, foliar fertilization.

Abstract:

In this paper we analyse existing experimental data (grain yield and yield components) from seed rate experiments on wheat in Western Australia, with the aims of determining which factors most influence the optimum plant population, and advancing some practical guidelines for improving the choice of seed rate under rain-fed conditions. Experiments (32) were conducted in the rain-fed cropping zone of Western Australia between 1996 and 2001, using factorial combinations of wheat cultivars (3–25) and target plant populations (4 or 5). Some of them also contained treatments of nitrogen fertiliser (0 or 40 kg/ha of N) or sowing times (2). Each cultivar × plant population dataset (248) was considered to be a record for the sake of the subsequent analyses. Actual plant numbers were counted in each experiment and the optimum plant population was estimated when the slope of an inverse polynomial curve (choosing the most appropriate of the LDL and QDL models in GenStat) fitted to each record was 2.5 kg/ha of grain yield for each extra plant/m2. The optimum populations were initially grouped using a regression tree technique into groups with similar characteristics using pre-sowing rainfall, rainfall in the growing season, sowing date, and soil type. The variables cultivar and nitrogen fertiliser rate were later added to the regression tree analysis. Yield components available for most experiments were used as an aid to interpretation of the results. The optimum plant population varied from 35 to 175 plants/m2 and average grain yields varied from 0.42 to 3.91 t/ha. Rainfall in the growing season (sowing date to harvest date) provided the first split in the regression tree, but pre-sowing rainfall (January to sowing date), sowing date, and soil type further modified the optimum population. The addition of N fertiliser rate as a variable in the regression tree did not induce any different groupings of the optimum population sets, but cultivars were grouped into 4 response types according to pre- and post-sowing rainfall amounts. Where rainfall in the growing season was <205 mm, improved growing conditions due to more pre-sowing rainfall, earlier sowing, and more seasonal rainfall, were associated with higher optimum plant populations. Where rainfall in the growing season exceeded 205 mm, higher pre-sowing rainfall was associated with lower optimum populations. The optimum population was greater on sands than on clay loams. However, on sandy loam soils the optimum was less where rainfall in the growing season was <291 mm, or more for crops sown after 27 May at rainfall >291 mm. Increases in yield components in response to improved growing conditions above about 400 culms/m2, 300 ears/m2, 10 000 kernels/m2, and 600 g/m2 of dry matter at anthesis were not associated with higher optimum plant populations. In general, the optimum plant population increased at about 40 plants/m2 for each tonne of grain yield up to about 3.0 t/ha. The effect of cultivar on the optimum population appeared at yield levels above 2.5 t/ha, but was only detectable when the rainfall in the growing season exceeded 205 mm. Growing conditions and cultivars associated with lower weight per ear (due to fewer kernels and/or lower kernel weight) were associated with higher optimum plant population when the rainfall in the growing season exceeded 205 mm. It is suggested that farmers can make better estimates of the appropriate plant population (and hence can calculate seed rate) on the basis of pre-sowing rainfall (likely stored water), rainfall zone (probability of rainfall in the growing season), sowing date, soil type, and characteristics of individual cultivars where known.

Abstract:

AbstractPresented paper investigates the application of a line voltage changer to an installation for pre-sowing seed treatment by pulsed electric field (PEF) in order to increase the sowing quality of seeds and to suppress pathogenic microflora. The installation comprises an AC voltage regulator, a high voltage source, a voltage inverter, a working chamber for seed treatment, a control unit, and current and voltage sensors. The proposed installation differs from the existing apparatuses as it automatically provides the transformation of the pulsed electric field parameters by constant monitoring of power processes in a layer of treated seeds and feedback sending to the control unit. Seed treatment efficiency depends on the dose being determined by the parameters of electric field, namely, intensity in the seed layer, pulse duration, pulse repetition frequency, and seed treatment time. The parameters of rational treatment were determined, and the minimum treatment dose was calculated on the basis of results from the laboratory tests on the effect of pulsed electric field on sowing qualities of winter wheat seeds. It was experimentally confirmed that the proposed installation provides automatic transformation of electric field parameters depending on the changes taking place in the seed layer on the example of seeds with different moisture content maintaining the necessary treatment dose, ensuring the stability and repeatability of results.
