MOLINET-SALAS, Dariel  and  LESCAY-BATISTA, Elio. Phenological phases and yield components in nine soybean cultivars (Glycine max L.) in Granma province. cultrop [online]. 2021, vol.42, n.3, e02.  Epub Sep 30, 2021. ISSN 0258-5936.

In order to evaluate the phenological phases and yield components in nine soybean cultivars, in the dry season, on a soft fluvisol soil, an investigation was carried out in areas of the “Jucaibama” Agricultural Experimental Station, belonging to the Institute of Agricultural Investigations "Jorge Dimitrov", located on the Bayamo-Mabay highway km 13½, Bayamo municipality, Granma province. The sowing was carried out in the month of December 2016, with a sowing frame of 0.70 m between rows and 0.05 m between plants, in plots of four rows of five meters long, for a total area of 14 m2, in a randomized block design with four replications. A double classification analysis of variance was performed and the multiple comparison of means was performed using the Tukey test for p≤0.05. Different responses were observed between varieties in all the variables evaluated, except at full physiological maturity. The Vencedor and Brillante varieties expressed yields of 1.86 and 1.85 t ha-1, respectively, without significant differences with the varieties IS-24, IS-1, IS-36, William-82 and IS-27, which showed yields between 1.46 and 1.67 t ha-1.

Keywords : phases; flowering; fruiting; maturity; variables.
