Seed distribution by punch seeder in family farming

ABSTRACT Family farming seeks to use less-aggressive agricultural practices, however, there is little machinery available that is suitable for the reality of this sector. This has led to the use of technically incorrect practices, which have contributed to the impoverishment, compaction and desertification of agricultural soils. Punch seeders are seen as a promising alternative for carrying out sowing in family farming, as they employ localised seed distribution with less disturbance of the soil and the consequent preservation and conservation of its structure. The aim of this study was to evaluate the quality of seed distribution by a punch seeder used in family farming. The experiment was carried out in a soil classified as a Red-Yellow Argisol. Descriptive statistics were used to evaluate the quality of seed distribution by the punch system. Statistical Process Control was adopted to evaluate quality control in the seed distribution process. The results showed that the performance of the punch seeder was similar to that of the precision pneumatic seeder, with 90.2% acceptable spacing. As demonstrated by the SPC study that showed the process to be compatible with quality standards, the punch seeder is therefore a viable alternative in the sowing process for family farming, since an improvement in sowing quality, with a precision of 88.4% was obtained. The punch system resulted in less soil disturbance when compared to the disc harrow and manual seeder, and proved to be an effective solution for conservation agriculture.
