Влияние биостимуляторов роста и микроэлементов на фотосинтетическую деятельность посевов и семенную продуктивность клевера гибридного

Experimental data on the influence of plant growth biostimulants and microelements on the photosynthetic activity of crops and seed productivity of hybrid clover cultivated on drained sod-podzolic gley soils in the northern part of Belarus are presented. The results of observations of leaf area, photosynthetic potential, net productivity of photosynthesis on seed crops of hybrid clover, their relationship with biostimulators under study, and seed yield are presented. The most promising biostimulants are identified.
