Crop description

Green beans are vegetables with relatively high requirements, not only for the soil but also for temperatures. For proper development, they require temperatures falling within the range of 20-25°C, they do not tolerate frost. The substrate for green bean cultivations should be rich in humus, loose, deep tilled and fertile. Cultivars should be sowed in the first or second year after fertilization with manure or compost. Green beans belong to legumes – plants from this family grow in symbiosis with Rhizobium bacteria due to the properties of binding nitrogen from the air. Green beans have a higher demand for micronutrients such as: molybdenum, iron, copper and boron. As green beans are sensitive to root damage, soil loosening and weeding, these treatments need to be performed with care. Green beans have the highest demand for potassium and phosphorus and a lower demand for nitrogen. They are also sensitive to chloride, therefore, fertilizers which contain potassium only in the form of sulphate need to be chosen. They also have high nutritional requirements as regards iron and phosphorus but, as other legumes, they have the ability to use this element from phosphates in the soil. A low soil pH reduces its availability for plants. Green bean yields, just as those of other plants, depend on fertilization – both with macronutrients and micronutrients. Micronutrients have a positive influence on nutrients taken up by the plants. The absence of a nutritional balance may cause the leaves to fall. The use of a compound fertilizer changes the morphological features of plants. This promotes pod formation and distinctly increases their number on the plant, thus also increasing the number and mass of seeds from the plant. Green beans respond the most to the lack of micronutrients such as manganese, molybdenum and zinc. The ProFit fertilizer was used in the foliar fertilization programme — the treatment is performed when plants have developed three leaves. It is foliar fertilization that ensures the good condition of plants by providing them with nutrients needed during a drought when the activity of the root system can be poor. The pod quality can also be poor due to water consumption disorders (crooked pods) and overly fast seed formation. The provision of phosphorus and boron in this period stimulates the improvement in pod and seed formation.
