Abstract
Soybean (Glycine max (L.) Merr.) is a plant that is gaining increasing popularity among farmers. It is valued for its high content of protein, fats, amino acids and B vitamins in the seeds, making it a versatile raw material for both the food and feed industries. Plant growth and development is greatly influenced by meteorological conditions and canopy weed infestation. During the 2024 season in Czesławice, weather conditions deviated from long-term averages – the total precipitation from March to August was 323 mm (84% of the long-term value), indicating moderately dry conditions. In addition, average air temperatures were higher than normal (e.g., by 3.7°C in March and by 3.1°C in May), which may have affected soybean pod formation. These meteorological conditions could have had a significant impact on the number of pods formed – both those with seeds and empty pods. Research was conducted in 2024 at the Experimental Farm in Czesławice, which is part of the University of Life Sciences in Lublin. The experiment was designed using a split-block method with three replicates. The study was carried out on soybean of the Viscount variety, classified as an early group (-000+). Various weed control methods were applied as the experimental factor: (i) Control treatment: plot not weeded; (ii) Mechanical method: plot mechanically weeded twice; (iii) Chemical method: plot weeded using prosulfocarb (800 g) and chizalofop-P ethyl (50 g). Soybean productivity was evaluated by determining the number of formed pods. In randomly selected plant samples, the number of full pods (with seeds), empty pods, and the total number of pods per plant were recorded. Autumn field cultivation involved deep plowing. The results were statistically analyzed using analysis of variance (ANOVA), and the significance of differences between means was assessed using Tukey’s test at a significance level of 0.05. Research showed that the chemical method of field protection had a significantly greater impact on increasing the number of formed soybean pods, which translated into higher plant productivity. Chemical field protection significantly influences the total number of formed soybean pods. Further research is needed to establish optimal cultivation conditions that take into account the variability of meteorological conditions.
