الوصف: | Potatoes are an extremely important crop for the nutrition of the population in Ukraine. Its potential is high-up to 100 t/ha of tubers, but the average yield reaches 14-16 t/ha. To obtain significantly higher productivity, it is necessary to improve the main elements of cultivation technology. The main factor of potato production on drip irrigation is the optimisation of plant nutrition, which the authors have taken to study with three varieties of early maturing potatoes. Studies have established that providing plants with nutrients with the selection of varieties can increase the productivity of tubers up to 37-39 t/ha, or increase its level compared to the control to 64.7%. It was determined that the maximum yield is provided by the main application from autumn N32P32K32, before planting N48P48K48 and carrying out three top dressings during the growing season simultaneously with watering with a total rate of N33 and Plantafol 6 kg/ha, starting from the beginning of budding with an interval of 8-10 days. At the same time, tubers are formed with high-quality indicators as they contain a sufficient number of dry substances, ascorbic acid (vitamin C), and starch. It should be noted that when optimising nutrition, the intake of all the main indicators of potato tubers compared to the control slightly decreased, namely dry substances and starch. On the contrary, the amount of ascorbic acid increased, especially with top dressing with Plantafol. Varietal features regarding the impact on the quality of tubers are also determined. Significantly more dry substances were found in tubers of the Riviera and Prada varieties, and more starch content was found in Prada and Minerva varieties. Slightly less dry matter and ascorbic acid were detected in Minerva potato tubers compared to other varieties. From the grown crop of tubers of the studied potato varieties, it is possible to obtain up to 4.0 t/ha of bioethanol or alcohol if they are processed |
