Abstract: Investigations were carried out in 2011–2012 Alexander Stulginskio University (ASU) "Food agronomic inputs and zootechnical research lab. The influence of spring wheat cultivar 'Monsun'. The study used Fertiactyl Starter liquid ferti-lizers with chemical composition: NPK (13–5–8) + a proprietary organic extract (activated humus (humic and Fulvia) acids, glycine betaine, zeatin). Vegetative experiment of spring wheat sprayed with water (control variant) and liquid complex fertilizers with organic extracts 0,025 %, 0,05 %, 0,1 % and 0,5 % concentrations. Spring wheat sown in 5 l pots. Each vegetative container grown in 25 plants. The experiment was conducted in four replications. Plants were grown in peat substrate at pH – 5,5 to 6,5, total nitrogen – 170 mg l-1, phosphorus (P2O5) – 120 mg l-1 potassium (K2O) – 150 mg l-1. Liquid NPK fertilizers with organic extracts increased the height of the young shoots of spring wheat. We found that the more intensive growth during the period was characterized by plants, the grains were sprayed with 0.05% of the solution. Liquid NPK fertilizers with organic extracts of photosynthetic pigments content and leaf area assimilation had no substantial impact. The highest chlorophyll a (1,49 mg kg-1) and chlorophyll b (0,53 mg kg-1) content determined using 0,5 % solution. Maximum assimilation leaf area (51,12 cm2), grew wheat sprayed with 0.1 % solution
