THE INFLUENCE OF MAIZE GROWING TECHNOLOGIES ON PLANT PARAMETERS AND PRODUCTIVITY

Abstract

A two-way experiment was conducted in Jonava district, Užusaliai in 2024 in 4 repetitions in order to determine the influence of different maize growing technologies on maize plant’s biometric and yield structure indicators. Different growing technologies were selected, such as growing technology the owner of the experimental field has already been using before the start of the experiment and owner’s growing technology without use of micronutrients (factor A); growing technologies with different fertilization rates recommended by spectral reflectance sensor (factor B). 5 plants from each repetition field were randomly selected to measure plant’s height and mass, knob mass, 1000 grain mass, grain productivity. According to research data, usage of micronutrient fertilizers had significant influence on plant’s height and had a tendency to increase value of every other biometric and yield structure indicator, while best results were found using micronutrient fertilizers together with medium rate of fertilizers recommended by spectral reflectance sensor.
