Mapeamento da qualidade de semeadura da cultura do milho

Abstract

The increase in the technology field by sowing and modern tractors, allows much cases the higher seeding speed. However, this advance should benefit from seeding, so as to deposit the seed in the soil in an appropriate manner, both in depth and in quantity. Thus, the aim was to map and assess the quality of sowing of maize. Data collection was carried out in a commercial area in which they were allocated 84 sampling points, and collection at each point with three replications. They evaluated the plant stand and longitudinal distribution of plants. Data were analyzed using descriptive statistics, geostatistics and statistical quality control (SQC). Normal longitudinal distribution has not reached the target of 90% of normal spacing for precision seeder. The SQC has shown instability for plant stand and control of spacings. The SQC and the spatial dependence for spacings classes indicates regularity in the distribution of seeder, distance and number of satisfactory samples for future evaluations of the longitudinal distribution of maize plants in the area.
