Assim o objetivo do trabalho foi produzir sementes de soja enriquecidas com diferentes doses de Mo e verificar o comportamento destas sementes quanto à qualidade fisiológica e nutricional, além de utilizar estas sementes de soja enriquecida com molibdênio para a semeadura na próxima safra, e analisar seu comportamento quanto à presença e ausência de molibdênio no início da cultura. O experimento foi desenvolvido na Fazenda de Ensino, Pesquisa e Extensão/UNESP - Campus de Ilha Solteira, localizada no município de Selvíria - MS, em um Latossolo Vermelho distrófico de textura argilosa. O experimento foi realizado em dois anos, sendo o cultivar utilizado BRS Valiosa RR. No primeiro ano foram utilizadas três doses de molibdênio (0, 400 e 800 g ha -1 de Mo), com quatro repetições, aplicadas via foliar, metade da dose nos estádios R 3 e outra metade em R 6 . No segundo ano as sementes obtidas no primeiro ano foram semeadas para formação de dois experimentos conduzidos paralelamente, sendo que um experimento foi realizado em blocos casualizados com esquema fatorial 3x3, com três métodos de aplicação (sem aplicação de molibdênio, aplicação de molibdênio no momento da semeadura na dose de 25 g ha -1 de Mo, e aplicação via foliar no estádio V 4 na dose de 25 g ha -1 de Mo) e sementes com três teores de Mo obtidas no ano anterior. O segundo experimento foi em blocos casualizados em esquema fatorial 4 x 4 x 3 (épocas de aplicação x doses x sementes com teores de Mo diferentes), com quatro repetições. As quatro épocas de aplicação foram: V4, no pré florescimento, em R3... / Studies have shown the importance of using molybdenum (Mo) in soybean worships taking this micronutrient great importance in the nitrogen fixation process, especially for being part of the nitrogenase enzyme, which is responsible for supplying nitrogen to the soybean plants. The objective of this study was to produce soybean seeds enriched with different doses of Mo and verify the behavior of these seeds by physiological and nutritional quality, and using these soybeans enriched with molybdenum for sowing next season, and analyze their behavior for the presence or absence of molybdenum at the beginning of the crop. The experiment was conducted at Experimental Station belongs to UNESP - Ilha Solteira, located in Selvíria - MS, in a clayey Oxisol. The experiment was conducted in two years using BRS Valiosa RR cultivar. The first year was used three molybdenum doses (0, 400 and 800 g ha -1 ), with four replicates, applied to the leaves, half the dose in stages R3 and the other half in R6 stage. In the second year the seeds obtained in the first year were sown for the formation of two experiments conducted in parallel. The first experiment was conducted in a randomized block design in a x3 factorial scheme: three application methods (without application of molybdenum, molybdenum application at the time of seeding in a dose of 25 g ha -1 Mo, and foliar application at V4 stage in a dose of 25 g ha -1 Mo) and seeds with three Mo contents obtained in the previous year. To second experiment was used a randomized block design in a factorial scheme 4 x 4 x 3: 4 application times x 4 doses of Mo x seeds with 3 different Mo content, with four replications. The application times were: V4 stage, pre flowering, R3 and R5 stage, and the doses: 0, 25, 50 and 100 g ha -1 Mo, and seeds with three levels of Mo obtained in the previous year. There enrichment of seeds already in the first year at a dose of 400 g ha -1 ...
