- Abstract
Crop biomass is valuable not only from a nutritional and fodder point of view, but also from an energetic point of view. The main task is to increase biomass production while maintaining low nutrient and pesticide requirements and low ecological footprint. A stationary three-year field experiment was performed at the Experimental Station of Vytautas Magnus University, Lithuania, in 2020–2022. Single crops and mixtures of maize, hemp, and faba bean were investigated in terms of their biomass productivity. Results showed that as the crop diversification increases, the productivity of maize and hemp grown in the mixture decreases, while faba bean ensures high dried biomass productivity. During the three years of the experimentation, the highest total dried biomass was found in the ternary crop: on average, 1495.4 g m−2 per year. The highest dried biomass of the ternary crop was established in the first year of experimentation: 2081.1 g m−2. A decrease in biomass yields in the second and third years of the experiment was observed in all treatment plots. The results suggest that the low fertilization level (totally N 45, P 45, K 45 kg ha−1) in the experiment should be increased if multi-crop cultivations are to be regrown during vegetative seasons.
