Resumo: | The use of desiccants is an alternative to anticipate the soybean harvest and keep the physiological quality of seed. The objective of this work was to assess the production performance and germination seeds in response to differents stages and desiccation chemicals products to early harvest of soybean cultivars. The experiment was conducted in Campos Novos, in two harvests, it was used a randomized complete block design disposed in split-split-plots. Two phenological stages of application (stage R7.1 and R7.3) were tested in the main plot. Five soybean cultivars (NA 5909 RG, CD 2585 RR, BMX Turbo RR, SYN 1059 RR and BENSO 1RR were evaluated in the subplots, and three desiccants ammonium glufosinate, paraquat, carfentrazone-ethyl in the 2011/12 season and one control (without the desiccant application) were evaluated in the sub-subplots. In the 2012/13 season the carfentrazone-ethyl was substituted by diquat. It were evaluated the number of the days in the early harvest, yield, number of pods per plant, number of seeds per pod, mass of 100 seeds and germination percentage. The chemical dessecation with the use of glufosinate ammonium and paraquat applied in R7.1 stage allowed to anticipate the harvest in six days (2011/12) and provided maintenance germination percentage (90% and 92%) compared to control (76%). The dessecation didn’t influence negatively on seeds productivity, but reduced the mass of seeds in the two growing seasons, and early harvest was dependent of pre-harvest rain absence, with this preamble. The use of dessicants is a possibility of early harvest in production field of soybean seeds. |

O objetivo deste trabalho foi avaliar o desempenho produtivo e a germinação de sementes em resposta a diferentes épocas e produtos químicos para dessecação e antecipação da colheita de cultivares de soja. O experimento foi conduzido em Campos Novos, em duas safras agrícolas sob o delineamento em blocos casualizados, dispostos em parcelas sub-subdivididas. Na parcela foram testados dois estádios fenológicos de aplicação (R7.1 e R7.3), nas subparcelas cinco cultivares de soja (NA 5909 RG, CD 2585 RR, BMX Turbo RR, SYN 1059 RR e BENSO 1RR e na sub-subparcela foram aplicados três dessecantes (glufosinato de amônio, paraquat e carfentrazone na safra 2011/12) e uma testemunha. Na safra 2012/13 o carfentrazone foi substituído pelo diquat. Foi avaliado o número de dias de antecipação da colheita, a produtividade de sementes, o número de vagens por planta, o número de sementes por vagem, a massa de 100 sementes e a germinação. A dessecação química com o uso de glufosinato de amônio e paraquat aplicados no estádio R7.1 permitiu antecipar a colheita em seis dias (safra 2011/12) e proporcionou a manutenção do percentual de germinação (90% e 92%) em comparação a testemunha (76%). A dessecação não influenciou negativamente a produtividade de sementes, mas reduziu a massa de sementes nas duas safras agrícolas, e a antecipação da colheita foi dependente da ausência de chuva na pré-colheita. Os dessecantes podem ser usados na antecipação de colheita em campos de produção de sementes de soja.
