“…In a study carried out by [25], a positive effect of Mo on N2 fixation was verified since there was more N accumulated per root and nodule mass, that is, greater radicular and nodular efficiency in N absorption, corroborating in part with the results obtained in the present study. Similarly, in a study conducted by [5], it was noted that the increase in the dose of mineral nitrogen fertilizer provided a reduction in N2 fixation, thus corroborating the increase in the concentration of mineral N in the soil solution, thus disfavoring the symbiosis between plant and the rhizobia. The N concentration in the soil solution is due to the accumulation of nitrite and nitrate at the root level, which can reduce the availability of the bacteroid.…”

“…Common bean (Phaseolus vulgaris L.) belongs to the Fabaceae family andis the most cultivated species of bean worldwide [1], feeding more than 300 million people across the globe, especially in Latin America, Africa, and Asia, with Brazil being the world's largest producer of the species [2,3]. The total area of common bean production globallyin 2020 was 29 million hectares, with a production of 27 million tons [4], the nutritional issue being Agronomy 2024, 14, 1368 2 of 15 one of the factors that corroborates this low level of yield, with emphasis on nitrogen (N 2 ), the nutrient most demanded by the crop [5].…”

Biological nitrogen fixation (BNF) can provide the necessary nitrogen for bean crops; however, for this to occur, important limitations involving the inoculant application technology need to be overcome.The use of co-inoculation is a management technique used to obtain benefits and increase the potential of N2 fixation from the association between bacteria from the rhizobia group, such as R. tropici, and bacteria that promote plant growth, such as A. brasilense, in association with the addition of nutrients that allow greater efficiency of bacteria fixing atmospheric N2. This study aimed to evaluate the bean response to the reinoculation of R. tropici in co-inoculation with A. brasilense in a mixture with the micronutrients Co/Mo, in the winter season of 2021, in Anápolis-GO, Brazil. A randomized block design was used, with four replications, and the following treatments (TRs) were studied: TR1—reinoculation with R. tropici; TR2—reinoculation with co-inoculation of R. tropici + A. brasilense; TR3—reinoculation of R. tropici + Mo/Co micronutrients; TR4—reinoculation with co-inoculation R. tropici + A. brasilense + Mo/Co micronutrients; TR5—inoculation via seed, without reinoculation; TR6—mineral N fertilization in the sowing furrow and topdressing; TR7—control, without any N source. At stage R6, nodulation characteristics (number and dry mass of nodules) and the morphophysiological parameters of the plants (main root length, root dry mass, plant height, shoot dry mass, leaf area, and leaf N content in the shoot) were evaluated. At harvest, the final plant stand and components (number of pods per plant, number of grains per pod, and average weight of one hundred grains) were determined, in addition to grain yield. It was concluded that inoculation followed by reinoculation in topdressing with R. tropici in co-inoculation with A. brasilense plus Mo/Co, compared to mineral nitrogen fertilization, improves the efficiency of the nodulation process and the morphophysiological characteristics of the common bean crop. Seed inoculation and topdressing application with R. tropici, associated with co-inoculation with A. brasilense + Mo and Co, have the potential to completely replace mineral nitrogen fertilization in common bean crops.

“…In a meta-analysis (99 studies) on side-dressing nitrogen fertilization in common bean in Brazil under no-tillage system, Pias et al (2022) found that organic matter content and previous crop were the main factors that affected the response of the crop to nitrogen fertilization. According to the authors, if common bean is cultivated after grasses, the N rate to be applied as side-dressing should be up to 30% higher when compared to the succession with another legume.…”

“…Nitrogen is the nutrient most extracted by common bean and one of those that most limit its yield (Ambrosano et al, 1997;Pias et al, 2022;Wutke et al, 2022). In conventional fertilization recommendations in Brazil, 90 kg ha − 1 of N is used in the phenological stage V 4 (three fully expanded trifoliate leaves) when common bean is grown in NTS after grasses and in irrigated areas (Ambrosano et al, 1997).…”

The management practices impacts on a crop succession system in newly implemented no-tillage area should be investigated to provide more accurate recommendations. A two-year experiment was conducted in Southeastern Brazil to evaluate the interactions between crop succession (grasses/legume) and nitrogen splitting fertilization in common bean in a production system with newly implemented no-tillage. The plots were formed by three crop succession schemes, with grasses cultivated in spring/summer and the legume crop (common bean) in winter.The cropping systems in spring/summer were: sole maize, maize intercropped with U. ruziziensis and sole U. ruziziensis. The subplots consisted of ten splitting schemes of side-dressing nitrogen fertilization in common bean, with applications in the phenological stages V 3 , V 4 and R 5 . The common bean grain yield (GY) was 5 to 12% lower when it was cultivated after sole U. ruziziensis compared to other successions. However, when U. ruziziensis was intercropped with maize, the GY of common bean was similar to that obtained in the succession with sole maize. In addition, the intercropping had little effect on the maize agronomic performance. Compared to the application in a single rate, the GY of common bean was on average 12% higher when nitrogen fertilization was split, and the best schemes were 45-00-45 and 45-45-00. Nitrogen fertilization in common bean did not affect the GY of maize in succession. Intercropping of maize with U. ruziziensis and nitrogen splitting fertilization in common bean in succession allows obtaining the ecosystem bene ts promoted by the forage without affecting the cash crops yield.

“…Moreover, that study found more species in the eld, likely due to the differences in drilling techniques. Dry bean growers commonly use no-tillage practices in Brazil(Pias et al 2022), so soil preparation is expected to be less intensive than for carrots and onions, which require a very ne seedbed preparation. The seedbed preparation for carrot and onion elds signi cantly reduces the structure and the availability of other food sources, which could explain the even lower number of birds observed.…”

Agricultural landscapes in Brazil provide habitat to various bird species, some of which may be exposed to pesticide-treated seeds that have not been fully incorporated into the soil during drilling. Understanding the dynamics and interactions between birds and freshly drilled fields is crucial for developing sustainable farming practices that balance agricultural food production with wildlife conservation. This study investigated the presence and abundance of birds and the availability of pesticide-treated seeds in four onion fields and seven carrot fields in the Brazilian State of Minas Gerais. Bird surveys were conducted using scan sampling and point count methods to observe diversity and behavior before and after crop drilling. For carrot and onion fields, the study found that seed incorporation rates varied according to the distance from the field edges, with close to the edge having lower rates. In carrot fields, bird monitoring showed a decrease in observed species and individuals on the day of drilling, with an increase in bird sightings after drilling. In onion fields, similar trends were observed, with the species composition changing after drilling and a significant decrease in species abundance on the day of drilling. None of the species found foraging in the field after drilling were granivorous or omnivorous. These findings indicated that carrot and onion fields offer limited food sources for granivore bird species due to high seed incorporation rates and intensive seedbed preparation. The research suggests that freshly drilled carrot and onion fields are generally unattractive to foraging birds, with low seed exposure and a reduced likelihood of contact with pesticides applied as a seed treatment.
