“…The biological N fixation does not supply an adequate amount of N to bean plants (Coelho et al, 1998;Silva et al, 2004). Furthermore, several researchers have reported that N fertilization improves nutritional and yield parameters of common bean (Silva et al, 2004;Amaral et al, 2016). However, there is still a great lack and conflict of information related to the amount of N provided on the physiological aspects of the common bean seeds.…”

Several studies have shown that cover crop can increase common bean (Phaseolus vulgaris L.) yield. However, little is known about the influence of cover crop mixtures in association with topdressing N fertilization on common bean seed quality. We, therefore, evaluated the physiological quality of common bean seeds produced under cover crop residues and N fertilized in a no-till farming system. A 5 × 4 factorial experiment (cover crops and N rates) was performed under field conditions in Mato Grosso do Sul, Brazil. Single-specie and cover crops mixtures [pearl millet (Pennisetum glaucum), pearl millet-jack bean (P. glaucum; Canavalia ensiformis), pearl millet-pigeon pea (P. glaucum; Cajanus cajan), pearl millet-sunn hemp (P. glaucum; Crotalaria juncea), and pearll millet-velvet bean (P. glaucum; Mucuna pruriens)] were grown and common bean was planted in succession. Nitrogen fertilizer (50, 100, and 150 kg N ha-1) was topdressed applied to common bean at the V4 stage. At maturity, common bean plants were harvested, and physiological quality of seeds was assessed. The first germination count, final germination, germination speed index, accelerated aging, and N and protein concentration were influenced by cover crop residues and/or N rates (main effect). A cover crop × N rate interaction was observed for seedling dry biomass after germination and accelerated aging. All treatments produced seeds with high physiological quality. Although the cover crops showed variable results, the application of 100 kg N ha-1 in topdressing slightly improved seed quality attributes compared to the other N rate treatments. We conclude that addition of N fertilizer and cover crop treatments does not affect common bean seed quality to a large extent.

“…In the experiment irrigated 2013, grain yield was increased by topdressing N fertilization up to the estimated rate of 124 kg ha -1 . Crusciol et al (2007), Kaneko et al (2010), Soratto et al (2014), Amaral et al (2016), and Soratto et al (2017) also reported increases in the grain yield of common bean due to soil-applied N fertilization, which was related to the expressive effect of this nutrient on plant growth and fruiting. The foliar application of 5.0 kg ha -1 N-SR resulted in the highest grain yield, with an increase of 395 kg ha -1 (15.7%) compared with the control and of 253 kg ha -1 (9.5%) with the treatment with 2.5 kg ha -1 N-CU.…”

“…Nitrogen is the nutrient taken up in the greatest amount by the common bean crop (Perez et al, 2013;Soratto et al, 2013); therefore, its supply at suitable rates and times is fundamental for obtaining a high grain yield (Soratto et al, 2011(Soratto et al, , 2014(Soratto et al, , 2017Amaral et al, 2016).…”

“…Soratto et al (2004) observed an increase in common bean grain yield with the application of up to 129 and 182 kg ha -1 topdressing N under conventional soil tillage and a newly established no-tillage system, respectively. Kaneko et al (2010) and Soratto et al (2017) obtained increases in common bean grain yield with the application of up to 180 kg ha -1 N. Amaral et al (2016) evaluated the cultivation of common bean under different straw mulching -corn (Zea mays L., corn + Urochloa ruziziensis (R.Germ. & C.M.Evrard) Morrone & Zuloaga, and U. ruziziensis -and found increases in grain yield with the application of up to 136 kg ha -1 N.…”

The objective of this work was to evaluate the effect of applying N sources to leaves and N rates to the soil on the growth, N uptake, and grain and crude protein yields of the common bean (Phaseolus vulgaris) crop. Three experiments -two irrigated and one rainfed -were conducted during the 2012/2013 agricultural season, in a randomized complete block design with four replicates. The treatments consisted of the application of: four N rates (0, 45, 90, and 180 kg ha -1 ) to the soil, as topdressing in the V 4 stage; and five N sources/rates -i.e., control, without foliar N application; 2.5 kg ha -1 N as conventional urea (N-CU); 5.0 kg ha -1 N-CU; 2.5 kg ha -1 N as slow-release urea-formaldehyde (N-SR); and 5.0 kg ha -1 N-SR -to leaves, in the R 5 stage. Soil N fertilization, using rates between 124 and 180 kg ha -1 , increases shoot N content and uptake, number of pods per plant, grain yield, and protein content and yield. Regardless of the growing environment and N application to the soil, the foliar supply of N as slow-release urea-formaldehyde increases grain and protein yields, whereas the greatest rate of N as conventional urea also increases grain yield. Aplicação de nitrogênio via foliar e em cobertura na cultura do feijoeiro comumResumo -O objetivo deste trabalho foi avaliar o efeito da aplicação de fontes de N via foliar e de doses de N via solo no crescimento, na absorção de N e na produtividade de grãos e de proteína bruta da cultura do feijão comum (Phaseolus vulgaris). Foram conduzidos três experimentos -dois em condição irrigada e um em sequeiro -no ano agrícola 2012/2013, em delineamento de blocos ao acaso, com quatro repetições. Os tratamentos consistiram da aplicação de: quatro doses de N via solo (0, 45, 90 e 180 kg ha -1 ), em cobertura, no estádio V 4 ; e cinco fontes/doses de N via foliar -i.e., testemunha, sem N via foliar; 2,5 kg ha -1 de N na forma de ureia convencional (N-UC); 5,0 kg ha -1 de N-UC; 2,5 kg ha -1 de N na forma de ureia-formaldeído de liberação lenta (N-LL); e 5,0 kg ha -1 de N-LL -, no estádio R 5 . A adubação nitrogenada via solo, com doses entre 124 e 180 kg ha -1 , aumenta o teor e o acúmulo de N na parte aérea, o número de vagens por planta, a produtividade de grãos, e o teor e a produtividade de proteína. Independentemente do ambiente de cultivo e da aplicação de N via solo, o fornecimento de N na forma de ureia-formaldeído de liberação lenta via foliar aumenta a produtividade de grãos e de proteína, enquanto a aplicação da maior dose de N na forma de ureia convencional também aumenta a produtividade de grãos.Termos para indexação: Phaseolus vulgaris, adubação foliar, adubação nitrogenada, liberação lenta, ureiaformaldeído.

“…De acordo com Rossi et al (2012), a rápida liberação de P no período inicial da decomposição da braquiária está relacionada com a perda de P solúvel em água acumulada nos vacúolos dos resíduos vegetais, o que contribui para aumentar a disponibilidade do P para as plantas. Amaral et al (2016), estudando o efeito de diferentes palhadas sobre a produtividade do feijoeiro, também encontram maiores valores nas parcelas com palhada de braquiária (U. ruziziensis). Os dados de produtividade apresentaram comportamento quadrático em função das doses de P 2 O 5 , cuja dose de máxima eficiência agronômica foi calculada por meio da derivada primeira da equação e correspondeu a 234,58 kg ha -1 de P 2 O 5 (Figura 2).…”

The application of phosphate fertilizer is indispensable for the achievement of sustainable bean production, and P is necessary practically in the entire cycle. Thus, cultural management alternatives have been used in the best use of this nutrient, among them the use of Brachiaria as cover crop. The objective of this research was to evaluate the dynamics of phosphorus in the soil with and without the presence of Brachiaria brizantha cv. Marandú as cover crop, and the bean response to phosphorus fertilization. We used a randomized block design with a split plot arrangement; the plots were composed of P 2 O 5 doses (0, 50, 100, 200, and 400 kg ha -1 ) via triple superphosphate; and the subplots were composed of the presence and absence of Brachiaria as previous cover crop cultivation of beans. Soil samples were taken at 15 and 30 days after sowing (DAS) bean. In the samples, phosphorus fractionation in soil was carried out by the Hedley technique. Phosphorus content was evaluated in the leaf and grain yield of bean plants. The phosphorus fertilization and cultivation of Brachiaria brizantha cv. Marandú as cover crop provided changes in the levels of labile P of soil at 15 and 30 DAS bean, and labile P of soil only at 15 DAS bean. The presence of B. brizantha cv. Marandú as cover crop increases the P content in the bean leaf with consequent grain yield gain of 18%. A aplicação de fertilizante fosfatado é indispensável para obtenção de produções sustentáveis de feijão, sendo o fósforo (P) necessário praticamente em todo seu ciclo. Por essa razão, alternativas de manejo da cultura estão sendo utilizadas, visando ao melhor aproveitamento desse nutriente, dentre elas, o uso da braquiária como planta de cobertura. Objetivou-se, com esta pesquisa, avaliar a dinâmica do fósforo no solo, com e sem a presença de Brachiaria brizantha cv. Marandu como planta de cobertura, bem como avaliar a resposta do feijoeiro à adubação fosfatada. Utilizou-se o delineamento em blocos ao acaso, com arranjo de parcelas subdivididas; as parcelas foram compostas por doses de P 2 O 5 (0; 50; 100; 200 e 400 kg ha -1 ), por via do superfosfato triplo, e as subparcelas foram compostas por presença e ausência de braquiária como planta de cobertura, anteriormente ao cultivo do feijoeiro. Foram obtidas amostras de solo, aos 15 e 30 dias após a semeadura do feijoeiro. Nas amostras coletadas, efetuou-se o fracionamento de fósforo no solo, pela técnica de Hedley. Nas plantas de feijoeiro, avaliaram-se o teor de fósforo na folha e a produtividade de grãos. A adubação fosfatada e o cultivo de Brachiaria brizantha cv. Marandu como planta de cobertura proporcionam aumentos dos teores de P-lábil do solo, aos 15 e 30 DAS do feijoeiro, e de P-plábil (P pouco lábil) do solo somente aos 15 DAS do feijoeiro. A presença da Brachiaria brizantha cv. Marandu, como planta de cobertura, aumenta os teores de P da folha do feijoeiro, com consequente ganho de 18% na produtividade de grãos.Palavras-chave: cobertura vegetal; Phaseolus vulgaris; reciclagem de fósforo.
