EFFICIENCY OF SEEDLINGS CULTIVATION OF CELERY SALAD IN THE USE OF HYDROGEL
The aim of the research. To study the influence of different forms of hydrogel on growth, development of seedlings, and also the quality of leafstalks and the total yield of celery salad in open soil. The most optimal conditions establish for the growth and development of seedlings of celery salad. The morphological and biological characteristics of celery salad determine which will determine its marketable quality; to establish the total productivity of celery salad, depending on the method of growing seedlings; to pick up the o ptimal forms of hydrogel for growing seedlings of celery salad. Methods. Field methods, laboratory-field methods, statistical methods. Results. The influence of hydrogel on growing of celery salad seedlings in the conditions of the Right Bank Forest-Steppe of Ukraine was determined for the first time. It ware found that the use of different forms of hydrogel positively affects for the growth, development, the basic phenological phases, the total and commercial yield of celery salad. Conclusions. It was proved that variants using all forms of hydrogel had better height (+ 0.2–6.0 cm to control), the thickness of the root (+ 2.0–3.8 mm to control) and mass of the aboveground part (+0.5–1.6 g to control) than the control variant without the use of hydrogel. It was establish that the use of hydrogel during the cultivation of celery salad positively influenced the biometric indices of the plant and its yield. Thus, the use of hydrogel in the form of gel in the Anita v ariety helped to obtain 23.7 t/ha of high quality commercial products, which was an additional 6.9 t/ha before control. The yield of crops of Anita variety was higher in variants using gel (23.7 t/ha) and tablets (21.9 t/ha), which was 6.9 and 5.1 t/ha more than the control version. Below was the variant without introducing hydrogel – 17.5 t/ha. In addition, the yield level indicator had a strong direct correlation with the length and thickness of the petiole, the total and mass of the product. Found that the use of hydrogel was cost effective and cost effective. The best profitability was note with the use of gel in the variety Anita – 55.3%.
