Influência da velocidade de trator e semeadora de precisão na implantação e produtividade da cultura do milho verde
| Resumo: | The aim of this study was to evaluate the performance of a precision seeder on deploying and productive characters of the tillage corn. It was evaluated parameters of sower and the productivity of the culture. It was used a tractor Massey Ferguson MF 283 4x2 model TDA and precision seeder model SEED LINE. It was adjusted to 5.9 distributing seeds per meter (65.000 plants.ha-1), with 5 cm deep and 90 cm between rows. The experiment was a randomized block with three speeds and four replications, totaling 12 sampling units. For the operating speeds used were 7.0, 5.5 and 4.5 km.h-1. The results showed that the velocity affected on the peripheral speed of the dosimeter seeds, number of seeds, seed spacing, length and width of the sheet. Consequently, the fastest peripheral speed of the disc dosimeter affect the number of seeds (3.9 seeds) and seeds spacing at fastest speed. For the experimental conditions recommended to use the forward speed of 4.5 km.h-1. |
