“…The main abiotic factors limiting bean growth and productivity are drought (Androcioli et al., 2020; Arruda et al., 2019), high temperatures (Chavez‐Arias et al., 2018), aluminum toxicity (Santos Neto et al., 2020), and soils with low phosphorus (Tembo et al., 2019) and nitrogen (N) contents (Zeffa et al., 2020; Zeffa, Moda‐Cirino, Delfini, et al., 2021; Zeffa, Moda‐Cirino, Nogueira, et al., 2021). Although beans can fix atmospheric‐N (N 2 ) in symbiosis with bacteria of the genus Rhizobium , the fixation is less efficient than that of other legumes (Appelbaum, 2018).…”

Common bean (Phaseolus vulgaris L.) cultivars with higher nitrogen-use efficiency (NUsE) are considered to be the main strategy to reduce the dependence on nitrogen (N) fertilizers. In this sense, the objective of this study was to identify key traits and common bean cultivars with higher NUsE using multivariate statistical approaches.Forty carioca common bean cultivars were analyzed in four environments under absence-(0 kg N ha −1 ) and presence N (40 kg N ha −1 ) applied as top-dressing. A total of 15 NUsE-related traits were evaluated. Multivariate analyses of variance identified the presence of a three-way interaction of genotype, N level, and environment, showing that the differential behavior of cultivars depended on the N level and environment evaluated. Strong multicollinearity was observed among the total set of traits studied; however, after removal criteria used, a collection of eight traits remained for subsequent analyses. The path analysis indicated that the dry matter biomass could be used for the indirect determination of NUsE in contrasting N conditions. The cultivars IAC-Alvorada, IPR Sabiá, and IPR Saracura performed the best from those selected in both N conditions by factor analysis. The cultivars that stood out positively in this study can be used as parents in breeding programs aimed at developing cultivar with higher NUsE and less dependence on N fertilizers.

“…In addition to cultivars' adaptability and stability Zeffa et al, 2021), the management practices may favor or limit the plant's genetic potential due to factors such as nutrient use efficiency (Leal et al, 2019;Zeffa et al, 2020;2021) and water use efficiency (Fatumah et al, 2021).…”

In irrigated production systems, the common bean grain yield must reach high levels to maintain economic viability. In this context, management, like the selection of the most adapted cultivars, may be effective in obtaining high yields. Through a three-year experiment, it was aimed to select the common bean cultivars with the highest agronomic and technological performance in an irrigated production system and to determine the yield component that most interfered with common bean yield. The treatments consisted of eight common bean cultivars with indeterminate growth habit and from the pinto bean variety (carioca): ANFc 9, BRS Estilo, BRSMG Madrepérola, Pérola, IAC Alvorada, IAC Milênio, TAA Bola Cheia, and TAA Dama. IAC Milênio and IAC Alvorada had the highest agronomic performance for irrigated production systems, with grain yields up to 17% higher than other cultivars. The cultivars show little variation in the grain technological quality, meeting the culinary and nutritional qualities recommended for common bean. The ANFc 9 cultivar showed the highest crude protein content in grains (19%). The number of pods per plant is the yield component that most interferes with common bean grain yield, generating 86 kg ha-1 increments for each unitary increase. Therefore, the common bean cultivars selection in the irrigated production system is an effective management practice to increase common bean agronomic and quality performance.

The current recommendations for nitrogen (N) doses may not contemplate the complex dynamics of N in the soil, what may imply in insufficiency to the crop demand. This study aimed to evaluate the use of two portable chlorophyll meters (Minolta SPAD 502 and ClorofiLOG model CFL 1030), after defining the nitrogen sufficiency index (NSI), to estimate the nitrogen fertilization factor in modern bean genotypes. A block design was used, with four replications. Each experiment consisted of four treatments, with doses of 0, 5, 10 and 20 kg ha-1 of N for each 1 % considered below the NSI defined as adequate for each cultivar. At the end of the cycle, the production components and yield were evaluated. It was not possible to obtain precise adjustments in the methodology for the TAA Gol cultivar. The fertilization factor of 12.5 kg ha-1 of N for each 1 % below the NSI of 90 % proved to be efficient for the Pérola cultivar, when the SPAD-502 chlorophyll meter was used. In genotypes with size and cycle characteristics similar to those of the BRSMG Uai cultivar and the VR 20 strain, using a fertilization factor between 14 and 16 kg ha-1 of N, the NSI of 95 % must be reduced, in order to increase the efficiency of the nitrogen fertilization.
