Abstract
Abstract Fertilizers help to fill the missing nutritional elements for plants and affect their growth and the future crop. The paper presents the results of conducted studies on the effect of nutrient solution concentration on morphological and biochemical indicators of white cabbage seedlings. The seedlings of two early-ripe cabbage hybrids – Mirror F 1 and Tiara F 1 – were grown in peat substrate trays. A nutrient solution of 50 ppm (No.1) and 150 ppm (No.2) was used to feed the seedlings twice during the growing period. The obtained results showed the differences in experimental variants in terms of the height of seedling plants, the number of leaves and leaf-area duration, the weight and volume of the root system, total solids, content of sugar, ascorbic acid. The varietal reaction of cabbage seedlings to the introduction of root feeds with different concentrations was revealed. The nutrient solution No. 2 of hybrid plants Mirror F 1 stimulated the development of roots, their weight exceeded the control indicators (without fertilizers) by 37.3%, and the volume – by 37.8%, contributed to the increase of the content of solids (8.27%), general sugar (0.53%), ascorbic acid (78.79 mg%). When fed with nutrient solution No. 2 the seedlings of Tiara F1 hybrid were characterized by a large leaf-area duration, which exceeds the control by 1.3 times, and the indicators of the root system. The plants of this seedlings consisted of 49.5% of the root system. The chemical analysis of water in greenhouse farming for irrigation of plants showed that it contains various macro- and microelements that are necessary for the growth of vegetable seedlings. The concentration of the nutrient solution did not significantly affect the content of macroelements in the seedlings. When using nutrient solution No. 2, an increase in the plants of the two studied phosphorus hybrids was noted, a deficit of which is very often observed when growing seedlings.
