- Abstract
This paper aimed to determine the quality in the distribution of corn plants in the sowing line, in the Middle Plateau region of the State of Rio Grande do Sul. The study was carried out in the agricultural year 2018/19, in 23 maize cultivation areas, 14 in irrigated system and nine in rainfed system, located in 11 municipalities in the State of Rio Grande do Sul. In each area, the longitudinal distance between corn plants in the sowing line was measured, in the V3 vegetative stage. For that, 10 meters of plants were evaluated, in three repetitions. The data were tabulated and distributed between: acceptable, double and flawed spacing. According to the classification proposed in the classic literature, 56.5% of the evaluated areas are in an excellent state of distribution of plants in the line, 39.1% in good condition, and 4.4% of the areas in regular quality condition of corn sowing. When observing the two cultivation systems, the average of acceptable spacing was 87.0% for the irrigated system, and 93.8% for the rainfed one. Thus, it can be concluded that in most of the evaluated areas the quality of the corn sowing crop in the Middle Plateau region is great.
