Abstract

This study investigates sustainable agricultural practices through the integration of multifunctional microorganisms and crop diversification in soybean cultivation. The experiment was conducted at Embrapa Arroz e Feijão, using a 2 × 2 × 4 factorial design with randomized blocks and four replications. The treatments involved the combination of four multifunctional microorganisms (Burkholderia sp. (BRM 32111), Serratia sp. (BRM 63523), Bacillus sp. (BRM 63524), and the control, without microorganisms), two phosphorus levels (50% and 100% of the recommended P2O5 dose), and two cropping systems (soybean/rice/common beans or soybean/corn/common beans). Soybeans were cultivated in the summer (November-January), rice or corn during the off-season (January-May), and common beans in winter (June-September). The results showed that the use of rhizobacteria BRM 32111 and BRM 63523 resulted in the highest soybean yields, offering the greatest economic returns among the treatments. Additionally, cultivating rice in the off-season, combined with the use of phosphorus-solubilizing rhizobacteria, demonstrated significant potential as a sustainable agricultural practice by reducing chemical fertilizer use and improving crop nutritional efficiency, promoting agroecological sustainability.

大豆生产力和经济可行性与根瘤菌,耕作制度和磷剂量。
本研究探讨了大豆种植中多功能微生物与作物多样化相结合的可持续农业实践。实验在巴西农业研究中心(Embrapa Arroz e feij o)进行,采用2 × 2 × 4因子设计,随机区组和4个重复。处理包括4种多功能微生物(伯克霍尔德菌sp. (BRM 32111)、沙雷氏菌sp. (BRM 63523)、芽孢杆菌sp. (BRM 63524)和对照(不含微生物)、2种磷水平(P2O5推荐剂量的50%和100%)和2种种植制度(大豆/水稻/普通豆或大豆/玉米/普通豆)的组合。夏季(11月至1月)种植大豆,淡季(1月至5月)种植水稻或玉米,冬季(6月至9月)种植普通豆类。结果表明,施用BRM 32111和BRM 63523处理大豆产量最高,经济效益最高。此外,在淡季种植水稻,结合使用溶磷根瘤菌,通过减少化肥使用和提高作物营养效率,促进农业生态可持续性,显示出巨大的可持续农业实践潜力。
