In this macro stage it is necessary to pay attention to the similarity of the seeds. Variety similarity at 60-80%, similarity of hybrids at 92-98%. Factors such as the selection of high-quality seed, qualitatively prepared seed bed, seeding technique, seed treatment with micronutrients and favorable weather conditions have an impact on field similarity.

Germination is the beginning of plant development. The duration of this stage starts from dormancy to the appearance of sprouts, that is, until the first leaf sheath with a shoot appears on the soil surface. During seed germination, water is absorbed by the embryo, resulting in rehydration and cell expansion. Soon after water absorption or absorption begins, the respiration rate increases, and various metabolic processes that had been suspended or greatly reduced during the resting period are restored.

These events are associated with structural changes in the organelles (membrane bodies responsible for metabolism) in the cells of the embryo. For the reason that the spare materials are partially in an insoluble form, namely in the form of starch grains, protein granules, lipid droplets, etc., in fact most of the early metabolism of seedlings is associated with the mobilization of these materials and the delivery or movement of products to active sites.

Stocks outside the embryo are digested by enzymes secreted by the embryo, and in some cases also by special endosperm cells. Active embryo growth, except that resulting from swelling, usually begins with the emergence of a primary root, known as a seed root, although in some species (e.g., coconut) a shoot or perunus emerges first. Early growth depends mainly on cell expansion, but within a short time cell division begins in the root and young shoot, and then growth and subsequent organ formation (organogenesis) are based on the usual combination of increasing cell number and increasing individual cells.

In this macro stage, development occurs from the first true leaf and continues up to nine or more true leaves. At this stage, rudimentary stem nodes and internodes are laid down. The plant needs sufficient supplies of macronutrients such as phosphorus and potassium. When exposed to environmental and anthropogenic environments, amino acids must be used to eliminate them.

Leaves originate on the sides of the shoot tip. A local concentration of cell divisions marks the very beginning of the leaf; these cells then enlarge to form a nipple-shaped structure called a leaf support. Leaf support cells can be derived from the sheath or from the sheath and the casing. After that, the leaf support becomes more and more flattened in the transverse plane due to laterally oriented cell divisions and subsequent expansion on both sides.

The zones of separation are marginal meristemas, thanks to the activity of which the leaf acquires its lamellar shape. In each meristem, the outer array of cells or marginal initials contribute to the epidermal layers by prolonged separation. The cells below, also called submarginal initials, provide the tissue of the inner part of the leaf. Usually, a certain number of cell layers are defined in a layer such as the mesophyll, it is the parenchyma between the epidermal layers of the leaves.

Cell division is not limited to the region of marginal meristems, but continues throughout the leaf in each of the layers, always in the same plane, until the final cell number is approached. Then the speed decreases, stopping in different layers at different times. Sections usually end first in the epidermis layer and then already in the lower layers of the leaf mesophyll.

In this macro stage, the formation of second-order growth cones occurs, the available number of flowers in the inflorescence with the setting of the covering flower organs, the formation of anthers (microsporogenesis) and stigmas (megasporogenesis), and the formation of a greater number of synchronously developed productive stems. There is also intensive growth of organs in length, formation of ovules and pollen grains.

Applying nitrogen and phosphorus fertilizers can increase the number of flowers in an inflorescence. Although the structural organization of the vascular plant is relatively loose, the development of different parts is well coordinated.

Control depends on the movement of chemicals, including nutrients and hormones. An example of correlation is shoot and root growth. The increase of the aerial part is accompanied by an increased demand for water, minerals and mechanical support, which are satisfied by the coordinated growth of the root system. Several factors seem to be involved in control, as the shoot and the root affect each other mutually. The root depends on the shoot for organic nutrients, just as the shoot depends on the root for water and inorganic nutrients, and thus the flow of ordinary nutrients must play a role. The more specific control can be provided by supplying the nutrients needed in very small quantities.

The root depends on the shoot for certain vitamins, and changes in supply reflecting the metabolic state of the above-ground parts can also affect root growth. In addition, hormonal factors that affect cell division pass upward from the root to the stem; although the exact role of hormones, not yet established with certainty, they may be one way in which the root system can influence the activity of the shoot apex. Secondary thickening control is another important example of growth correlation. As the size of the shoot system increases, the need for both greater mechanical support and enhanced transport of water, minerals and elements is satisfied by the increased coverage of the stem due to the activity of the vascular cambium.

As a rule, the cambium of trees in temperate zones is most active in spring, when buds are blossoming and shoots are expanding, creating the need for nutrients. Cell division begins on each shoot and then spreads out from it. The terminal bud stimulates the cambium to divide rapidly through the action of two groups of plant hormones: auxins and gibberellins. The inhibition of lateral buds, another example of a correlated growth reaction, illustrates a reaction opposite to that occurring when controlling cambial activity. Lateral buds are generally depressed, as axillary shoots grow slower or do not grow at all, while the terminal bud is active. This so-called apical dominance is responsible for the characteristic unit of trunk growth seen in many conifers and herbaceous plants, such as the mallow. Weaker dominance leads to a form with multiple branching. The fact that the lateral or axillary buds become more active when the terminal bud is removed is indicative of a factor such as hormonal control. The flow of auxin from the shoot apex is partly responsible for inhibiting the axillary buds.

The nutritional status of the plant also plays a role; vervet dominance is strong when mineral supply and light are insufficient. For the reason that axillary buds are released from inhibition when treated with substances that stimulate cell division (cytokinins), it has been suggested that these substances are also involved in the regulation of kidney activity.

The potential yield of modern sugar beet varieties is extremely high. In Europe, the yield reaches 90-100 t/ha.

Sugar beet has high nutritional needs. Accumulation of nutrients occurs in three stages, each of which is dominated by potassium over other components, even over nitrogen.

When growing sugar beet, it is necessary to use boron, copper, manganese, and zinc microfertilizers. Iron and magnesium play an important role in the production of chlorophyll; manganese and molybdenum – in the oxidizing system of photosynthesis; zinc significantly affects electron exchange reactions; copper plays a leading role in respiration and photosynthesis.

Boron is the most critical element for sugar beet. Wonder Leaf Mono B 11 (B-11%), or Wonder Leaf Mono B 120 (B-9%), or Wonder Leaf Pink (B-20%). It has a great influence on the yield and sugar content of the roots, taking an active part in the metabolism of carbohydrates and the synthesis of cell wall material. Lack of boron leads to slow growth, twisting and wilting of leaves, and its deficiency leads to rotting of the heart and hollowness of root crops. Young leaves curl, turn black and rot. Root crops have poor shelf life, are damaged by rot. For a lack of boron (less than 0.2-0.3 mg/kg of soil), which can be observed on soils with a neutral reaction of the environment, where mobility is lower, during the period of sugar beet growth from the phase of the 6th leaf to the phase of leaf closure in the rows, foliar fertilization is necessary.

Copper fertilizers, on the example of Wonder Leaf Mono Cu 6 (Cu 6% chelate) are used on peat-bog soils. On sod-podzolic, gray forest, light sandy soils, they are applied once every five years.

Zinc fertilizers, in the example of  Wonder Leaf Mono Zn 8 (Zn-8% chelate) increase yield and sugar content on black soils with a small zinc content.

Manganese in Wonder Leaf Mono Mn 11 fertilizer (Mn-11 % chelate) helps to increase the yield of root crops and their sugar content. At the beginning of the growing season, it is necessary to ensure the formation of a high-yield type of plants. Manganese deficiency is observed on soils with a neutral or alkaline reaction. Low air humidity, low soil temperature, cloudy weather and high rates of mineral fertilizers prevent its assimilation. Signs of manganese deficiency: dwarfism of plants, yellow spots appear on young leaves, holes of various sizes, and their edges curl up. Foliar fertilizing with manganese fertilizers is carried out in the phase of 4-8 leaves. It is best to use fertilizers based on chelate compounds.

Copper in Wonder Leaf Mono Cu 6 (Cu-6% chelate) increases resistance to fungal and bacterial diseases, drought and heat resistance, promotes better assimilation of nitrogen. Copper fertilizers are used on sod-podzolic and gray forest soils. Lack of copper is caused by high rates of mineral fertilizers, liming of soils, and high temperatures. A solution of copper sulfate or copper chelates is used for foliar fertilizing of sugar beet, which is carried out before closing the leaves in the interrows.

Zinc in Wonder Leaf Mono Zn 8 (Zn-8 % chelate) increases heat and drought resistance of plants, resistance to disease damage. High rates of nitrogen and phosphorus fertilizers, lime, and low temperatures prevent its assimilation. Foliar feeding of sugar beet with chelate compounds is carried out before closing the leaves in the interrows.

Sugar beet responds positively to foliar fertilizing with microfertilizers in all areas of beet sowing. Application of micro-fertilizers has a positive effect on the course of biochemical processes in the plant, which helps to reduce morbidity, increase yield and quality. Highly effective are microfertilizers on a chelate basis are, in which the coefficient of use of microelements is 90- 95%, which is ten times higher  than that of mineral salts.

It is important that foliar fertilization with microfertilizers is carried out precisely during the critical phases of plant development. On sugar beet crops, the most effective is two-time fertilization: the first in the phase of 4-6 (8) leaves , before the closure of the plants in the rows , the second 10-12 true leaves, before the closure of the rows .

In the phase of 4-6 leaves, it helps to stimulate the growth and development of plants, increase resistance to adverse weather conditions, to diseases and to compensate for the deficiency of trace elements.

At the same time, during this period it is advisable to use fertilizers with a high content of boron Wonder Leaf Pink (B-20%), which affects the yield and sugar content of root crops.

In the period of 10-12 formed leaves, the next treatment is carried out with microfertilizers such as Wonder Leaf Wonder Micro (ME complex), which contributes to the increased consumption of the main elements from the soil, increases disease and drought resistance of plants and improves the quality indicators of the harvest.

Activation of plant growth

Nutrients are assimilated by root crops throughout the growing season. At the beginning of growth, beets consume relatively little nitrogen, phosphorus and potassium. However, during this period, its root system is still poorly developed, so young plants are quite sensitive to the presence of mobile compounds of nutrients in the soil, especially phosphorus Wonder Leaf Blue (N:P:K-10:53:10 + Zn-2 chelate , w/w %), or Wonder Leaf P 30 (N:P-4:30 + B-0.5, Zn -0.5 chelate, amino acids-1, organic acids-4, w/w %). For optimal growth of sugar beets, fertilizer should be applied leaf by leaf. This method makes it possible to determine the best mode of plant nutrition in the period of 15-20 days after the emergence of seedlings and not only accelerates the growth of plants, but also increases resistance to diseases, pests and adverse weather conditions.

Prevention of hollowness and “rotten hearts”

Sugar beet is a borophilic crop that reacts very sensitively to the lack of this element. Boron promotes the growth and stretching of the cells of the main parenchyma of the roots, increases the heat resistance of plants and helps to accumulate sugar. Soils of Ukraine contain boron, but almost 90% of this element in the soil is immobile and inaccessible to plants. A lack of boron in sugar beets causes the death of the growth point, young leaves and tissues of root crops. The first signs are manifested in the wilting of the youngest leaves of the rosette of the heart, which then turn black, die and rot. This disease is called “heart rot”. With its further development, the leaves of the following tiers wither, become covered with brown spots, and then die, which can cause the death of the entire plant.

Due to the lack of boron, there is underdevelopment of the cells of the main parenchyma are underdeveloped in the form of cavities in root crops. Pathogens quickly penetrate these cavities, causing rotting of the root crop from the inside.

One of the methods of overcoming this problem is the introduction of boron-containing fertilizers, i.e. Wonder Leaf Mono B 11 (B-11%), or Wonder Leaf Mono B 120 (B-9%), or Wonder Leaf Pink (B-20%). Due to the fact that boron is a slow-moving element, it should be applied in small doses at the early stages of plant development. It is better to apply such fertilizers simultaneously with 2-3 treatments and during fungicidal treatments.

The optimal amount of boron for the normal development of root crops is 100-150 g/ha in the active substance.

Prevention and overcoming the consequences of stress

Plants are exposed to numerous stresses that often affect their performance. The most common factors that can cause stress in plants include: extreme temperatures (both low and high), lack of moisture (drought), excess water in the soil, excessive soil salinity, low or excessive light, exposure to phytopathogens (microorganisms and fungi), ultraviolet radiation, the influence of heavy metal ions. Even the use of chemicals causes stress. Scientists are working to reduce the impact of various negative factors on plants and help them prepare for extreme situations.

In most cases, the response of plants to stress factors is the inhibition of development, discoloration of leaves, falling flowers and fruits. Sugar beet often experiences stress due to incorrect calculations of herbicide doses, excessively high air and soil temperatures, etc.

One of the ways to neutralize stress factors and increase plant resistance to them is the use of Wonder Leaf Amino 43 (amino acids of vegetable origin-43%, w/w %) and Wonder Leaf Green (amino acids of plant origin – 15% + ME formula developed for the bipartite group, w/w %).

For the most part, these products are based on amino acids of different origin, phytohormones, steroids and similar compounds.

The mechanism of action of antitressants is manifested in the unblocking of enzymatic processes that were stopped by the stress factor, and the increased production of phytoalexins by the plant – substances that fight the effects of stress. Biostimulants of organic origin with a high content of amino acids and phytohormones activate plant nutrition and start biochemical processes. Also, when adding small doses of biostimulants to the tank mixture with plant protection agents, the absorption of the active substance of the plant protection agent is accelerated, which in general increases its effectiveness.

Accumulation of sugars

Sugar beet roots accumulate sugar in the last phases of the growing season. Therefore, it is very important to preserve the leaf apparatus on plants for active photosynthesis. As a rule, when applying fungicides, they try to save the leaves from being affected by diseases. During the development of root crops, the weather conditions are usually unfavorable: high temperatures and strong solar radiation negatively affect the accumulation of sugars and their flow to the root crops.

Transpiration from the leaf surfaxw can be reduced with the help of potassium. Potassium in the marginal cells of the stomata accelerates their closure at high temperatures, reducing water evaporation. Also, thanks to potassium, active synthetic processes take place and a larger amount of carbohydrates is formed, which quickly move to the main parenchyma of root crops.

The use of potassium-containing fertilizer Wonder Leaf Red (N:P:K-10:20:30 + B-2, w/w %) helps to increase the yield of root crops and significantly increases sugar content.
