Biological nitrogen fixation and agronomic features of soybean (Glycine max (L.) Merr.) crop under different doses of inoculant
Soybean is one of the most important crops in the world and presents great versatility. This study aims to investigate the effect of the Bradyrhizobium japonicum inoculant at 0, 600 and 1200 mL ha-1 on soybean crop, with and without 1 L ha-1 calcium (Ca 41%) + 0.4 L ha-1 boron (B 14%). Plants were grown for 90 days in plastic pots with 3 kg of sand and vermiculite (v/v) autoclaved at 121oC for 1 h. The experiment was conducted in a completely randomized design with five replications in a greenhouse. Soybean yield parameters were evaluated, such as, dry weight of shoot, root and total; plant height, nitrogen in the shoot; number and dry weight of nodules; chlorophyll index in the leaves; number of pods per plant (NPPL); number of grains per pod (NGP); and number of grains per plant (NGPL). The addition of Ca + B increased significantly NPPL, NGPL and NGP. The NPPL, NGPL were significantly increased with 600 mL ha-1 of the inoculant. The dose of 600 mL ha-1 of the inoculant combined with Ca+B significantly stimulated NPPL, NGPL and NGP. It is concluded that the productivity of soybean was increased with addition of 600 mL ha-1 inoculant, in combination with Ca and B.

La soya es uno de los cultivos más importantes del mundo y presenta una gran versatilidad. Este estudio tiene como objetivo investigar el efecto del inoculante Bradyrhizobium japonicum a 0, 600 y 1200 ml ha-1 en cultivo de soya, con y sin 1 L ha-1 calcio (Ca 41%) + 0,4 L ha-1 boro (B 14 %). Las plantas se cultivaron durante 90 días en macetas de plástico con 3 kg de arena y vermiculita (v / v) tratadas en autoclave a 121°C durante 1 h. El experimento se realizó en un diseño completamente aleatorizado con cinco repeticiones en un invernadero. Se evaluaron los parámetros de rendimiento de soja, tales como, peso seco del brote, raíz y total; altura de la planta, nitrógeno en el brote; número y peso seco de los nódulos; índice de clorofila en las hojas; cantidad de mazorcas por planta (NPPL); número de granos por pod (NGP); y número de granos por planta (NGPL). La adición de Ca + B aumentó significativamente NPPL, NGPL y NGP. El NPPL y NGPL se incrementaron significativamente con 600 mL ha-1 del inoculante. La dosis de 600 ml ha-1 del inoculante combinado con Ca + B estimuló significativamente NPPL, NGPL y NGP. Se concluye que la productividad de la soya se incrementó con la adición de 600 mL ha-1 de inoculante, en combinación con Ca y B. A soja é uma das oleaginosas mais importantes no mundo e possui grande versatilidade. O objetivo deste estudo foi estudar o efeito da inoculação de 600 e 1200 mL ha–1 de um inoculante líquido com Bradyrhizobium japonicum e com ou sem adição de 1 L de cálcio ha–1 (Ca 41%) e de 0,4 L de boro ha–1 (B 14%) na cultura da soja. As plantas foram crescidas por 90 dias em potes plásticos com 3 kg de areia: vermiculita (v:v) autoclavados (121ºC, 1 h). O experimento foi conduzido em delineamento inteiramente casualizado, com 5 repetições em casa de vegetação. Foram determinados parâmetros relacionados com o desenvolvimento e produtividade da soja, como: a massa seca da parte aérea, de raízes e total, nitrogênio da parte aérea, número e massa seca de nódulos, índice de clorofila das folhas, número de vagens por planta (NVPL), número de grãos por vagens (NGV) e número de grãos por planta (NGPL). A adição de Ca+B aumentou significantemente NVPL, NGPL e NGV. O NVPL, NGPL foram aumentados significantemente com a adição de 600 mL ha–1 inoculante. A adição de 600 mL ha–1 inoculante juntamente com a adição de Ca+B estimulou significativamente o NVPL, NGPL e NGV. Conclui- se que a produtividade da cultura da soja foi aumentada com a adição de 600 mL ha–1 inoculante juntamente com a adição de Ca e B.
