EFFECTS OF DIFFERENT TILLAGE AND SEED RATE ON BEAN CROP

Abstract

The study was conducted in 2022. In Jonava district at Kęstutis Janušaitis farm. Beans were grown in the experimental field using different tillage technology and different seed rates. One of the technologies used was minimum tillage and the second was direct seeding into the uncultivated soil. Seeding was also done using four different seed rates in both tillage technologies. After carrying out a two-way statistical analysis between different technologies, it was observed that the density of plants after germination was significantly the lowest (25.2 pcs. m^-2) when directly sowing in the uncultivated soil with a seed rate of 300 kg ha^-¹, and significantly the highest (44.7 pcs. m^-2) when sowing directly into uncultivated soil, the maximum seed rate is 450 kg ha-¹. After assessing the density, a second time before harvesting. A significantly lower bean crop density was found for direct seeding in no tillage at 300 kg ha^-¹ and significantly higher in direct seeding in no tillage at 450 kg ha-¹ compared to minimum tillage. Tillage technology applied at the seed rate of 350 and 400 kg ha^-1 did not have a significant effect. When evaluating the yield of beans, we can say that the sowing method does not have such a significant influence as a properly chosen seed rate, this is shown by the results obtained: the worst result was the bean crop in fields with minimal tillage, sown using a seed rate of 300 kg ha^-¹. By increasing the seed rate from 350 to 450 kg ha^-¹, the yield of bean seeds increased significantly (15.4-25.2%).
