GROWTH INDICES, YIELD, BIOCHEMICAL COMPOSITION AND QUALITY OF DRIED MELON PRODUCTS UNDER VARIOUS BACKGROUNDS OF FERTILIZERS

The article presents the results of a study to identify the effects on growth, plant formation, and yield, yield of dried products and quality indicators of summer melon varieties for various backgrounds of fertilizers. Using organic fertilizers at a rate of 30 t/ha of manure + N150P150K60 kg/ha, an extension of the vegetation period by 3-5 days was revealed, the longest stems were formed (251.0-275.3 cm), the largest number of stems (4.0 -5.3 pieces), leaf surface area (2618-2791 dm2 ), bush thickness (1902-2093 g), root mass (134-177 g) and plant productivity (10.2-12.1 kg). The highest yield (28.5-34.0 t/ha) was obtained from the melon varieties when grown against organic fertilizers (30 t/ha of manure + N150P150K60 kg/ha), with a commodity yield of 27.4- 32 8 t/ha or 96.1-97.3%. The yield increase was 4.9-5.6 tons or 119.1-123.4%. And in the composition of the grown fruits was the largest amount of dry matter (12.2-13.4%), sugars (9.4-10.7%), vitamin “C” (15.30-23.16 mg/%), the nitrate content was 42.16-53.65 mg/kg, which is 1.8-2.0 times lower than the maximum permissible norms. With the artificial method of drying the fruits of selected varieties of melon the highest yield (10.0-13.6%) and yield (3.22-4.16 t/ha) of dried products with a high dry content were obtained substances (81.4-84.0%), total sugar (65.3-68.1%), vitamin “C” (23.4-42.5 mg/%), with a qualitative assessment of 9.4- 10.0 points, with the gelability of drying, the quality of dried products was estimated at 8.2-9.3 points.
