“…This result demonstrates the advantage of including this forage species in the crop succession, and plants of the genus Urochloa have great capacity to accumulate N in their tissue (Carmeis-Filho et al, 2014), that is, they increase the N cycling rate, reducing the need for reapplying mineral N fertilizer for the common bean crop Soratto et al, 2013). Mingotte et al (2020) observed that sole U. ruziziensis promotes up to 139% and 80% higher N accumulation in straw compared to the amount N accumulated in sole maize and maize intercropped with U. ruziziensis. Barbosa et al (2021), evaluating N fertilization managements in white oat crop in succession to U. brizantha, observed that the management without top-dressing N fertilization led to yield similar to that obtained with the highest dose applied (160 kg N.ha -1 ).…”

“…The cultivation of common beans after these cropping systems promoted higher values of germination, first germination count and seedling emergence speed index. The effect of crop remains on seed quality is probably related to the quantity and quality of plant residues deposited on the soil, considering that they have varying effects on its chemical properties and, consequently, on plant nutrition (Arf et al, 2011;Coelho et al, 2020;Mingotte et al, 2020).…”

“…Given the positive results of the forage for protein content in the seeds, U. ruziziensis possibly supplied a greater amount of N to the soil compared to maize residues. This fact is related to the lower C/N ratio of Urochloa straw compared to that of maize, a characteristic that confers greater cycling of N and other nutrients (Soratto et al, 2013;Mingotte et al, 2020). N plays a fundamental role in the metabolic pathways of synthesis of organic molecules, being considered a structural component of free and protein amino acids (Marschner, 1995).…”

“…Usually in irrigated areas common bean is cultivated after some grass, especially maize. Producers also often use cover crops, such as U. ruziziensis, aiming at straw production for implementing a no-tillage system or even for nutrient cycling and reducing the potential of pests and diseases (Mingotte et al, 2020). In addition, there are also producers who intercrop maize with U. ruziziensis so as not to lose the benefits of the two crops, that is, the revenue generated by maize and the benefits generated by U. ruziziensis (Carmeis-Filho et al, 2014).…”

The aim was to evaluate the effects of previous crop and top-dressing nitrogen fertilization on the yield and physiological and sanitary quality of common bean seeds. The design used was in randomized blocks in a split-plot scheme, with four replications. The plots were represented by three previous crops (sole maize, maize + Urochloa ruziziensis and sole U. ruziziensis), preceding common bean. The subplots consisted of N doses (urea) applied as top-dressing (0, 40, 80, 120 and 160 kg N.ha-1) when the common bean had four expanded leaves. Physiological quality and sanitary quality of the seeds were evaluated through germination tests, first count, emergence speed index, accelerated aging, seedling emergence in the field and pathogen incidence, in addition to crude protein content, 100-seed weight and yield. The study factors did not interfere in the sanitary quality of the seeds. Under U. ruziziensis straw, the highest seed yield was obtained with the N dose of 115 kg.ha-1, while under sole maize and intercropping straw, the increase in yield was linear. Previous crop with U. ruziziensis, whether cultivated as sole crop or intercropped with maize, promotes greater physiological quality of common bean seeds, while top-dressing nitrogen fertilization does not interfere with quality, weight and protein content of the seeds.

Determining nitrogen (N) accumulation and export by common bean as a function of straw and of the splitting of this nutrient is very important, aiming at the management and sustainability of agricultural systems. This study aimed to determine the N accumulation and export by common bean as a function of Zea mays and Urochloa ruziziensis grass straw (maize, maize/U. ruziziensis intercropping and U. ruziziensis) and splitting of top-dressing N fertilization. The experiment was conducted in Jaboticabal-SP-Brazil, during the 2012/13 crop season, in a Red Eutrophic Oxisol (Eutrudox) in no-tillage under irrigation. The experimental design was a randomized block with split plots with four replicates, totaling 120 subplots sized in 25m2 each. The plots consisted of the cropping systems prior to common bean: maize, maize/ U. ruziziensis intercropping and U. ruziziensis. The subplots were composed of ten top-dressing N fertilization splitting schemes (NS) at the phenological stages V3, V4 and R5 in different combinations. Common bean grain yield differs among cropping systems and as a function of top-dressed N split application. U. ruziziensis grass as single crop promotes greater N accumulation in common bean shoots compared to maize and its intercropping with U. ruziziensis grass. Regardless the cropping system, top-dressing N application in a single dose (90 kg ha-1) at V4 leads to similar accumulations and exports to those found in the absence of N fertilization. Splitting schemes with N application at the R5 stage increase the exports of this nutrient by common bean in succession to maize and its intercropping with U. ruziziensis grass.

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.
