Quality of soybean seeds in response to nitrogen fertilization and inoculation with Bradyrhizobium japonicum 1

Abstract: Nitrogen fertilization may interfere in the quality of soybean seeds. This study aimed to determine the physiological and sanitary quality of soybean seeds, in response to levels and times of nitrogen (N) application associated with Bradyrhizobium japonicum inoculation. Treatments were arranged in a randomized block design, in a 2 × 3 × 4 factorial arrangement [two soybean cultivars (BRS 1074 IPRO and ST 797 IPRO), three application times (sowing, 30 and 50 days after emergence) and four N levels (0 kg ha-1, 2… Show more

“…Importantly, neither drought nor high air temperature is favorable for the symbiosis of soybean and B. japonicum [11]. Neither is low temperature [9], often observed in Central Europe, as it can have a negative effect on the symbiosis of Rhizobia bacteria and it can make the available Bradyrhizobium inoculation unsatisfactory [46]. Popovic et al [23] suggest, however, that mineral N fertilization can reduce the effects of drought, and thus increase the seed yield, especially when environmental conditions improve [42].…”

“…Therefore, an important procedure in soybean cultivation is the inoculation of seed with symbiotic bacteria Bradyrhizobium japonicum (Jarecki et al, 2016;Martyniuk et al, 2018). As a result of this treatment, a high seed yield can be obtained with no or limited nitrogen fertilization of soybean plants (Zuffo et al, 2018). The bacteria Bradyrhizobium japonicum are rare in Polish soils (Narożna et al, 2015).…”

“…Deste nutriente dependem os processos enzimáticos, a síntese de aminoácidos e proteínas, bem como de moléculas de hormônios vegetais (citocinina), da clorofila e de material genético (KOLLING; OZELAME., 2017; TAMAGNO et al, 2017;ZUFFO et al, 2018). O uso eficiente do nitrogênio envolve dentre outros fatores a dose, a época de aplicação e a interação bactérias mutualística que promovem a fixação biológica de nitrogênio (FBN) MERCANTE et al, 2017;AGUILAR et al, 2018;, 2018;BRAZ et al, 2018;HERNÁNDEZ-LÓPEZ et al, 2018a;2018b;LANGE et al, 2018;PERES et al, 2018;SANTANA et al, 2018 Climatograma do período correspondente ao experimento para a produção de sementes da cultivar superprecoce de feijão-comum BRS FC104 no município de Santo Antônio de Goiás, estado de Goiás, nas coordenadas geográficas 16°29'51,5" S; 49°17'03,4" W O solo da área experimental foi classificado como Latossolo Vermelho distrófico (SANTOS et al, 2013), com 348 g kg-1 de argila, 270 g kg-1 de silte e 383 g kg-1 de areia, sendo classificado como franco-argiloso.…”

“…aplicado às plantas (agricultura verde por diminuir o dano ao ambiente), mas isso não é consenso (videGOMES JÚNIOR et al, 2008). De modo geral, esses estudos negligenciam aspectos básicos da biologia de sementes -como a composição química e a cinética do processo de germinação stricto sensu -, relacionando qualidade de sementes unicamente à capacidade de formação de plântulas (videNAKAGAWA, 2012; PERES et al., 2018;ZUFFO et al, 2018; ALVES et al, 2019). Apesar de uma visão abrangente sobre as funções bioquímicas dos elementos essenciais (GENT;FORDE, 2017;MURRAY et al, 2017;NAEEM et al, 2017), ainda há falta de conhecimento sobre até que ponto a disponibilidade de nutrientes para a planta-mãe afeta a qualidade das sementes e, subsequentemente, a germinação e o estabelecimento de plântulas.…”
