Effect of nutritional elements on the productivity of common beans (Phaseolus vulgaris L.)

Four Lithuanian and foreign cultivars of common beans were investigated at the Lithuanian Research Centre for Agriculture and Forestry during the 2019-2020 period. The experiment was carried out in the experimental field where 5 different combinations of macro-and micro-nutrients and growth regulators were applied. Yield of seeds, the number of pods plant^‑1, the number of seeds pod^‑1, and the seeds’ weight were estimated. It was determined that the productivity of the common bean is influenced by the genotype and the combination of nutritional elements applied. The tendency of a higher yield of seeds and the number of pods per plant formation was observed in the combination where nutritional elements NPK 6-16-3 + microelements and amino acids were used. Cultivar ‘Carlo’s Favorit’ distinguished the results of the highest productivity up to 5.26 t ha^‑1. Plants of the mentioned cultivar formed an average of 77 pods. Local population No.4 was distinguished with the highest weight of seeds. The weight of 100 seeds reached up to 54.8 g.
