Variability of the yield in soybean cultivars (Glycine max L.). Part I. Time of cold
Main Article Content
Abstract
The research was developed in the areas of the Base Technological Science Unit, Los Palacios, Pinar del Río, belonging to the National Institute of Agricultural Sciences. Four soybean cultivars were used (DV-5, DVN-6, DT-84, D-2101), which were sown on three different sowing dates (December 2011, January 2012 and December 2012), corresponding to the cold season, on a Hydromorphic Gley Nodular Ferruginous Petroferric soil. The objective was to evaluate the variability of yield in soybean cultivars (Glycine max (L.) Merrill), associated to meteorological variables according to date of sowing in the cold season. A randomized block experimental design with three replications was used, and the agricultural yield and its components were evaluated, as well as meteorological variables (temperatures, solar radiation, relative humidity), in different phenological stages of the crop cycle. Taking into account the results obtained, the highest values of agricultural yield correspond to the highest values of temperature and solar radiation (December 2012), reaching a better result the cultivar D-2101 with a value of 2.31 t ha-1. The components most associated with yield were the number of pods / plants and the number of grains / plants for the three planting dates in general. Of the climatic variables evaluated, the ones that most influenced the different phases were temperature and solar radiation.
