Photosynthetic and biological productivity of sugar beets depending on the fertilization system

Aim. To study the impact of an alternative organic-mineral fertilization on photosynthetic and biological productivity sugar beet under modernizing it with latest agrochemical means. Меthods. Short-term field analytical. Results. The results research different saturation agrochemicals beets are presented. It was established that development leaf surface, content chlorophyll in leaves, increased significantly when foliar fertilizing carried out against background fertilization. Conclusions. Application N30 + «Folcrop Combi» Amin» for 5 t/ha straw P90K90 plowing N90 pre-sowing cultivation formed maximum surface: July – 1920 cm2/plant, August 2566, September 1790 cm2/plant. specified ensured leaves 2.01%, 1.94%, 1.80%. net photosynthesis plants application mineral fertilizers compared to control without 1.60 times, additional 1.77-1.93 times. most intensive processes occurred combined − 11.08 g/m2 per day. use a modernized (5 undern Amin») highest beet: yield roots 60.3 t/ha, harvest 10.37 exceeding by 19.1 3.20 t/ha.
