The use of phosphate-solubilizing bacteria (PSB) can be a sustainable strategy to increase phosphorus availability and promote satisfactory crop yields. The objective of this study was to evaluate whether inoculation with PSB in common bean increases (i) growth, (ii) nutrition, (iii) yield, and (iv) grain quality, and (v) reduces the chemical phosphorus application dose to obtain maximum yields. The experiment was conducted in an Oxisol using a randomized block design in a 4 × 4 factorial scheme, with four replicates, using the cultivar IAC 2051. The first factor was four doses of P₂O₅ (0, 20, 40 and 60 kg ha⁻¹), and the second factor was four doses of PSB (0, 100, 200 and 300 mL ha⁻¹). For leaf area and leaf chlorophyll content, the association of PSB inoculation with a P₂O₅ dose of 40 kg ha⁻¹ promoted the best conditions for the common bean. P₂O₅ application increased yield by 79 kg ha⁻¹ for each 10 kg ha⁻¹ added. PSB inoculation at a dose of 192 mL ha⁻¹ promoted P export of 15.3 kg ha⁻¹, and the PSB dose of 159 mL ha⁻¹ increased yield by 389 kg ha⁻¹ (12%) compared to the control. Grain quality remained within the standards required by the consumer market, being little affected by the treatments. Improvements in common bean growth and nutritional and physiological status promoted by P₂O₅ application and PSB were essential in increasing yield, so these are sustainable production strategies.

Proper nitrogen management helps to optimize the use of chemical fertilizers, making it necessary to identify optimal rates and methods of application to obtain high yield. The aim was to evaluate the effect of application methods of nitrogen rates in top-dressing on the agronomic and qualitative characteristics of common bean. The experiment was conducted in the autumn-winter 2022 harvest, using the early cycle common bean cultivar IAC Polaco1849. A randomized block design was used, in a 2x3 + 1 factorial scheme with 4 replications. The treatments consisted of two N application methods (top-dressing and in line) and 4 top dressing rates (0, 50, 100 and 150 kg ha-1), with rate 0 being the additional treatment. Increasing rates of N of up to 100 kg ha-1 in top-dressing promoted higher yield values, mass of one hundred grains and sieve yield (RP) ≥12. The method of continuous application of N promoted an increase of 85 kg ha-1 in yield compared to top-dressing application. The application of N to common beans in line is an alternative management practice to increase legume yield by more than 3%.
