Variabilidade espacial dos componentes de produção da soja e perdas na colheita

Abstract

Precision agriculture is an important tool to maximize production, and consequently it is possible to make maps that indicate the location of critical areas, the rural producer to carry out localized interventions in order to increase productivity and consequently profitability. . In this context, the objective was to evaluate the spatial variability of soybean production and harvest components. The study was carried out in a commercial farm with data collection in two plots, being 70.46 (T1) and 63.14 ha (T2), coming from harvest corn and Brachiaria, respectively. They were: the plant stand, longitudinal distribution, plant NDVI and insertion of the first cow, productivity and the quantification of the pre-harvest and post-harvest heights of the machine, in each point of the sampling grid. The spatial analysis was carried out from the perspective of geostatistics, and later the maps of the variables were built. Spatial variability of soybean yield was confirmed in both lugs, accompanied by plant stand data, longitudinal distribution, yield components and NDVI. The losses of harvested soybeans are during the harvesting process, being greater during the harvest. Losses were well above 60 kg ha-¹, which in the literature.
