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 (KNO<sub>3</sub>) or growth regulators (gibberelic acid; GA<sub>3</sub>) improved the rate of germination of endive and chicory and reduced the mean germination time needed. 30 min pre-sowing treatment with NaHClO<sub>3</sub>, 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 NaHClO<sub>3</sub> treatment reduced plant growth of both species. The present study suggests that KNO<sub>3</sub> and secondly GA<sub>3</sub> 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:

Food is crucial for all life on the planet, however food security is a problem in many parts of the world (Van Straaten, 2006). In the last decade the number of undernourished grew to 1.02 billion (FAO, 2009). Shapouri et al. (2010) estimates by 2020 food insecurity will reach 500 million in SSA. In a world with limited resources, the only solution to meet food demand is by maximizing yield per unit of land (Van Straaten, 2006). Large-scale intensive farming is widely practiced in the US as a solution to this growing problem (Fyfe et al., 2006). Current food production practices are driven by mass production, which is highlighted by large inputs including pesticides, fertilizers, and irrigation. Although these techniques have revolutionized agriculture and helped combat world hunger, ill effects have been reported such as soil degradation and loss of biodiversity (Tilman et al., 2002). Alternative techniques can be introduced which increase plant production and are environmentally friendly, less costly, and less intensive (Theodoro & Leonardos, 2006). Two of these methods are magnetic fields and radiation (Aladjadjiyan, 2012). Magnetic fields were confirmed to affect plant growth, germination, metabolism, and vigor (Celik et al., 2009; Zuniga et al., 2016). Literature suggests pyramidal shapes harness the magnetic field of the earth to generate para magnetism within their structure (Van Doorne, 2013). Although pyramids have produced documented improvements in plant growth and germination (Kumar et al., 2010), the use of pyramids to incubate seeds before planting has not been tested. The purpose of this research was to describe the impacts of pre-sowing incubation within a pyramid on germination characteristics, seedling growth, seed desiccation, and soil condition, as well as describe any relationships existing between independent and dependent variables. Both wooden and copper pyramids were used, and seeds were incubated for periods of 5, 10, 35, and 45 days. A total of 1,800 seeds were tested. Data were analyzed in SPSS using one-way ANOVA?s at p<.05 significance level. Pyramids negatively affected germination frequency, percentage, time, and rate, but positively affected uniformity (synchrony, uncertainty, variation of germination time). Conclusions indicate longer incubation periods are beneficial for germination and uniformity, while shorter incubation periods increased vegetative growth. Copper pyramids exceled over wooden pyramids when examining seedling growth. Copper pyramids paired with longer incubation periods saw the highest increase in seed weight. The highest average soil temperature was recorded in the wooden pyramid, and soil pH remained unchanged.

Since in the 1994/1995 crop, occured an linear growth in area planted in system no tillage (NT), totaled in the 2010/11 crop 31.5 million hectares, accounting for 68% of the cultivated area. However, it is estimated that the loss of N applied in NT, can reach 78%. However, the application of N pre-sowing date has provided a result similar to traditionally applied. The experiment was conducted on the farm named of "Ilha de Cima" in Porto Firme, Minas Gerais, the forest region's, in a Red – Yellow Ultisol. Aimed to evaluate the efficiency of nitrogen fertilization with urea and granulated pearly in pre-sowing in the tillage system maize, with the desiccation of weeds. We evaluated the nitrogen fertilization (0, 40, 75, 110 and 150 kg ha-1) applied to the total area in the pre-seeding maize with the desiccation of weeds, time of nitrogen fertilizer in the pre-sowing in relation to desiccation (150 kg ha-1 N, 8 days before desiccation, even day, and 13 and 23 days after desiccation), the coverage nitrogen fertilization (0, 50, 100, 150 and 200 kg ha-1) in the V4 stage of development of the maize and yet forms of urea (pearly urea PETROBRAS - UPP, granulated urea PETROBRAS - UGT and granulated urea special - UGE). Thus the experiment consists of 28 treatments in an incomplete factorial, with the structure of a matrix Bacon, in a randomized block design with four replications. Weeds were collected in this area and they analyzed the contents of N and C. was planted maize bt (simple hybrid DKB 390 YG, early) with spacing of 0.9 m for a population of 50,000 plants per hactare. Were performed the quantification of the productivity, of the N absorbed by the shoot (Nab), of the recovery of N (RAN) and of the loss by volatilization of N. For productivity, we obtained a significant linear equation with a rate about 15 kg kg-1 N applied in coverage. There was also a linear response to the Nabs. And for the RAN was a decrease with increasing dose. In relation to the dose in pre-sowing there was a decline in productivity with increasing dose to the UPP, UGP and there was no significant difference to UGE. To the Nab and RAN there was no significant difference in UPP and UGP. However, for UGE an increase in the Nabs and RAN with increasing dose. How much the application time was difference significant only for productivity when used the UPP between 13 and 23 days after desiccation and to UGE between 8 days before with the other time. How much The N loss by volatilization was no significant difference for the different forms of urea. However in relation to the time we obtained the smallest loss when applied to 8 days before desiccation . Nitrogen fertilization in pre-sowing of corn in no-tillage system with the desiccation of weeds is effective. The UPP is more effective with the application before the desiccation of weeds, or in the maize planting. The UGP is most effective with the application in the weeds desiccation.
Desde a safra brasileira de 1994/95 ocorreu crescimento linear da área manejada com o sistema plantio direto (SPD), totalizando na safra 2010/11 31,5 milhões de hectares, correspondendo a 68 % da área cultivada. No entanto, estima-se que a perda de N aplicado no SPD, pode atingir 78 %. Porém, a aplicação do N na pré-semeadura da cultura tem proporcionado resultado semelhante ao aplicado tradicionalmente. O experimento foi realizado na propriedade “Ilha de Cima”, no município de Porto Firme-MG, região da zona da mata, em um Argissolo Vermelho - Amarelo. Objetivou avaliar a eficiência da adubação nitrogenada com ureia perolada e granulada na pré- semeadura do milho em sistema plantio direto, com dessecação das plantas espontâneas. Avaliaram-se a adubação nitrogenada (0, 40, 75, 110 e 150 kg ha-1) aplicada em área total na pré-semeadura do milho com a dessecação das plantas espontâneas; a época da adubação nitrogenada na pré-semeadura em relação à dessecação (150 kg ha-1 de N aplicados 8 dias antes, na dessecação e 13 e 23 dias após dessecação); a adubação nitrogenada em cobertura (0, 50, 100, 150 e 200 kg ha-1) no estádio V4 de desenvolvimento vegetativo do milho e ainda formas de ureia (ureia perolada PETROBRAS – UPP, ureia granulada PETROBRAS – UGP e ureia granulada especial – UGE). Desta forma o experimento constitui de 28 tratamentos, em um fatorial incompleto, com a estrutura de uma matriz Baconiana, no delineamento em blocos ao acaso com quatro repetições. Foram coletadas plantas espontâneas presente na área e estas analisadas quanto ao teor de N e C. Foi plantado o milho bt (híbrido simples DKB 390 YG, precoce) com espaçamento de 0,9 m para população de 50.000 plantas por hectare. Foram realizadas a quantificação da produtividade, o N absorvido pela parte aérea (Nab), a recuperação de N (RAN) e a perda por volatilização de N. Para produtividade, obteve-se uma equação linear significativa com taxa cerca de 15 kg kg-1 de N aplicado em cobertura. Também houve reposta linear para o Nab. E para a RAN houve uma queda com aumento da dose aplicada. Em relação à dose em pré-semeadura houve uma queda da produtividade com o aumento da dose para UPP, UGP e não houve diferença significativa para UGE. Já para Nabs e o RAN não houve diferença significativa para UPP e UGP. No entanto para UGE houve um aumento do Nabs e RAN com aumento da dose. Quanto às épocas de aplicação houve diferença significativa apenas para produtividade quando utilizou-se a UPP entre 13 e 23 dias após a dessecação e para UGE entre 8 dias antes com as demais épocas. Quanto a perda de N por volatilização não houve diferença significativa para as diferentes formas da ureia. No entanto em relação à época obteve-se a menor perda quando aplicou-se 8 dias antes a dessecação. A adubação nitrogenada na pré-semeadura do milho em sistema de plantio direto com a dessecação das plantas espontâneas é eficaz. A UPP é mais eficaz com aplicação antes da dessecação das plantas espontâneas, ou na semeadura do milho. A UGP é mais eficaz com a aplicação na dessecação das plantas espontâneas.

Abstract:
The coherent semantics of the sowing imagery (1Cor 15,36–44) suggest that heavenly bodies (v. 40–41) emerge from a process of body transformation, analogous to plants and animate beings (v. 37–39). The idea that the deceased are transformed into stars and thereby obtain a particular form of existence is widely attested in the mythography and in epitaphs of antiquity. In contrast to pagan conceptions about the dead permanently returning into celestial spheres, the heavenly bodies according to Paul represent a postmortem, albeit a pre-resurrection, stage in the development of human bodies. Accordingly, the heavenly body represents an intermediary ontological mode between the animated body of earthly creatures and the spiritual body of resurrection.

Abstract:
Variants of seed response to external disturbances were studied to determine the principles that should be followed during pre-sowing treatment. The approach that involves analysis of seeds' adaptive response has been applied. The basic organizational rules have been specified for external disturbance application to seeds. The use of informational method for studying the biological response of seeds on external actions made it possible to find the rules that have to be followed when pre-sawing treatment is performed with the use of electrophysical excitation. The essence of these rules is that the following sequence of operations shall be carried out in the process of pre-sowing treatment: to define the lowest energy level of external disturbance corresponding to the seed's sensitivity threshold, to organize cyclic action of external factors on seeds, to vary the amplitude of external factor within cycles, to vary the mode of external disturbance. The field experiments were carried out for several years, during which the pre-sowing treatment of seeds was determined.

Abstract:
The purpose of the research was to establish the mechanism of the magnetic field impact on seeds to determine the most effective mode of pre-sowing treatment of seeds in a magnetic field and design parameters of the device for magnetic treatment of seeds. It is established that under the influence of a magnetic field the rate of chemical reactions occurring in plant cells is accelerated, solubility of salts and acids increases, and permeability of cell membranes accelerates the diffusion of molecules and ions through them. This leads to an increase in the concentration of ions in the cell and oxygen molecules and the growth of water absorption of seeds. Pre-sowing seed treatment promotes increased germination by 25-40%, and germination by 30 - 35%. The most effective pre-sowing treatment of seeds in a magnetic field is a magnetic induction of 0.065 Tl with four reversal magnetization, a pole division of 0.23 m and a seed movement speed of 0.4 m/s. With this mode of treatment, crop yields increase by 20–25%.

Abstract:
Solving the problem of increasing plant resistance, the development of environmentally-friendly technologies is particularly important, which also contribute to the reduction of resource costs for production and load on the environment. The research results indicate a positive effect from the treatment of plants and seeds with electrochemically activated (ECA) water, electric fields, and impulse pressure (IP). Pre-sowing treatment of seeds with ECA water increases the germination rate and seed germination energy, improves the development of plants, improves morphological parameters, etc. The reactions of economically dangerous pests and causative agents of infectious plant diseases to the use of ECA water are identified. The combination of pre-sowing seed treatment with the treatment of vegetative plants provides the highest possible result.

Abstract:
To study the possibilities of pre-sowing seed activation, irradiation with LEDs emitting in the visible, violet, and near-ultraviolet ranges with a maximum of 405 nm was carried out. As a result of the growing experience, it was found that the height of wheat plants grown from the treated seeds significantly exceeds the control indicators except for the period of 45-55 days. To implement the flow, technology of seed activation with LEDs optoelectronic irradiation unit was developed. The advantages of the given installation are the energy efficiency and of seed treatment efficiency, due to of the optimal radiation spectrum selection and treatment doses.

Abstract:
Declining land and water productivity, rising global temperature, underground water availability, energy, labour availability, increasing cost of production, burning of crop residues and changing climatic conditions are major challenges faced by both scientists and farmers in South Asia. To address these challenges, different resource conservation technologies were promoted in the South Asia. Zero tillage was generally practiced in the region, which retains the previous crop residues on the soil surface while establishing main crop viz. wheat seeds directly drilled in standing anchored rice straw. Further such tillage systems required no pre-sowing irrigation which further improves the irrigation water productivity. The current chapter reviews the consequences of zero tillage on soil physical, chemical and biological properties, land and water productivity and in mitigating global warming potential in texturally divergent soils under different agro-climatic regions. Our review revealed that positive effects of zero tillage are visible only after 4-5 years up to which farmer might have to sacrifice some yields. Thus, there is need to recommend an integrated climate smart agriculture package/approach, which effectively solves weed pressure problems, helps in improving land and water productivity, mitigates global warming consequences and uplifts livelihoods in South Asia.

Abstract:
The influence of pre-sowing seed treatment of spring wheat varieties ‘Ester’ and ‘Leningradskaya 6’ with silicon-containing chelate microfertilizer (SCM) on the seedlings’ growth and development was studied. Varietal differences of spring wheat in response to pre-sowing seed treatment with SCM were revealed. For both wheat varieties, this fertilizer stimulates the germination energy and germination itself. Thus, after SCM treatment at a concentration of 5 mg/l, there was a significant increase in ‘Ester’ seed germination energy (by 19 %) compared to control, as well as by 20–27 % in ‘Leningradskaya 6’ variety. More pronounced stimulating effect of SCM was observed for ‘Ester’ at a concentration of 1.0 mg/l; the same for ‘Leningradskaya 6’ – at a concentration of 3.0 and 5.0 mg/l.

Abstract:
Three-year research, in the impact of microbial preparations and Gunatito on bean-root-nodule number and mass in organic production, was published. The highest nodule number and mass was in the year with a more favorable weather conditions, with a higher humidity. The lowest nodule number was in the method with a direct Tiffi application on the pre-sowing seed, whereas the lowest nodule mass was in the control variety. A positive insignificant correlation was determined between nodule number and mass, and yield. Nodulation was variety dependant. EM application 7 days before sowing, and the combination of Guanito before sowing with EM in flowering, showed a positive impact on nodule number and mass.
