STUDY OF GROWTH AND DEVELOPMENT PROCESSES OF SEED POTATO PLANTS DEPENDING ON FERTILIZER, GROWTH REGULATOR AND EXTRA-ROOT NUTRIENTS

The article presents the results of studies influence technological methods cultivation on processes growth and development seed potato plants. highest rates linear plant height were noted in variant where regulator Emistim C was applied against background fertilizer N46P46K46, both during treatment tubers germination phase, as well two foliar fertilizing budding phase after flowering with Micro-Mineralis microfertilizer. At same time, plants 79.2 75.0 cm, which is 9.2 8.2 cm higher than control variant, number 8.5 6.5 pcs, stems per 4.8 4.5 leaf surface area 22.7 22.0 thousand m2/ha. weight tubers, marketability depended intensification cultivation. mass planting their marketability, processing microfertilizer - 84.5 75.5 g, 4.0 g 90 74%, 6 4.5% respectively, varieties Bellarosa Opillya. Potato yields primarily varietal characteristics. yield variety 29.9 t/ha, compared to Opillya 19.5 t/ha. use N46P46K46 increased level 30.3 combined C, potatoes 30.7 20.2 respectively. productivity 33.0 22.9 by 3.1 3.4
