Photosynthetic activity of narrow-leaved lupine plants with various options for fertilization and seed treatment

Target. Intensification of photosynthetic activity narrow-leaved lupine plants in order to increase the level crop grain yield by creating optimal conditions for their growth and development due combination technological process dose mineral fertilizers calculated planned foliar top dressing with during critical periods development, as well seed treatment before sowing inoculant a fungicide. Ways. Field (to study interaction research object biotic abiotic factors); morphophysiological (for biological control over performance elements at stages organogenesis); weight establish parameters indicators structure determine grain); statistical (statistical processing results). Results. The basis increasing is intensification processes plant organims. Strengthening these impossible without optimizing nutrition system each corresponding life cycle organism. One ways solve problem balance nutrients agrocenosis complex single such main fertilizer, fertilizing microelements an accessible form seeds treated symbiotic nitrogen-fixing microorganisms biofungicide. results studies effect various doses fertilizers, bioinoculant disinfectant, fertilization fertilizer chelate different organogenesis on cultivar Peremozhets are presented. timing feeding plants, need pre-sowing biofungicide, were determined. Conclusions. Such agrotechnical measures (applying (N68P48K66) variety 3.5 t/ha, (1 l/t) biofungicide 3 kg/ha) II stage plants) contributed (the maximum leaf surface area (659.9 cm2/growth) was formed VIII organogenesis, most dry matter (13.1 g/growth) accumulated X which exceeded absolute values ​​by 138.8% 61.7%, respectively.
