Fertilizer application rates and recommendation for potato and root crops

  • To exact determination and calculation the required amount of fertilizer application, it is recommended to conduct soil agrochemical analysis, taking into account the planned yield indicators
  • We recommend to discuss nutritional special aspects with your regional manager

In this macro stage, you need to pay attention to the germination of the seeds. Variety similarity at 60-80%, similarity of hybrids at 92-98%. Field similarity is influenced by such qualities as the selection of high-quality seed, quality seedbed preparation, seeding technique, seed treatment with micronutrients and favorable weather conditions.

Germination is the beginning of plant development. The duration of this stage starts from dormancy to the appearance of sprouts, i.e. 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.

Since the spare materials are partially in an insoluble form, namely in the form of starch grains, protein granules, lipid droplets, etc., most of the early metabolism of seedlings is associated with the mobilization of these materials and the delivery or transfer 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 top of the shoot. 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 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, the submarginal initials, provide the tissue of the inner part of the leaf. Usually, a certain number of cell layers is defined in the mesophyll, which is the parenchyma between the epidermal layers of 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 and then in the lower layers of the leaf mesophyll.

In this macro stage, the formation of second-order growth cones, which are formed from the available number of flowers in the inflorescence with the laying down of the covering organs of the flower, also occurs the formation of anthers (microsporogenesis) and stigmas (megasporogenesis) and the creation of a greater number of synchronously developed productive stems.

Processes such as intensive organ growth, the formation of eggs and pollen grains take place. 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 in the aerial part is accompanied by an increased need 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. However, 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 affecting cell division pass upward from the root to the stem; although the exact role of hormones, is not yet established with certainty, that is, they may be one way in which the root system can influence the activity of the shoot apex. Control of secondary thickening 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 met by increased coverage of the stem through the activity of the vascular cambium. As a rule, the cambium of trees in temperate zones is most active in spring, when buds are budding and shoots are sprouting, creating a need for nutrients.

Cell division starts on each shoot and then spreads out from it. The terminal bud stimulates the cambium for rapid division through the action of two groups of plant hormones: auxins and gibberellins. 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 that is 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 evidence of 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 by treatment with substances that stimulate cell division (cytokinins), it has been suggested that these substances are also involved in the regulation of axillary bud activity.
