Inoculation in the planting furrow for grain crops in the lowlands of Rio Grande do Sul

Benefits of inoculation technology in the planting furrow for grain crops in the lowlands of Rio Grande do Sul was the theme of one of the technical lectures on the schedule of the 96th Expofeira de Pelotas on the afternoon of last Tuesday (04/10). Researcher Maria Laura Turino Mattos, from Embrapa Clima Temperado, spoke about the benefits and challenges of inoculation technology, a technological innovation in the lowlands of Rio Grande do Sul. Especially for rice and soybeans, research has already been carried out to validate inoculation technology in the planting furrow at the Terras Baixas Experimental Station of Embrapa Clima Temperado, Pelotas, RS. The research proved that there is no harmful effect of the inoculant application technology in the rice and soybean planting furrow on the survival of bacteria, that there is viability of bacteria to multiply and to remain alive in lowland soil and colonize the rhizosphere of plants. rice and nodule formation in soybeans. Among the advantages of inoculation technology in the rice furrow with diazotrophic and growth-promoting bacteria, the following can be highlighted: promotion of root growth resulting in greater absorption of water and nutrients from the soil, greater production of dry matter from the aerial part, greater plant population, number of tillers and panicles, greater productive performance of rice cultivars. In relation to the inoculation technology in the soybean planting furrow, we highlight the greater nodulation and growth of soybean roots, which promotes greater resilience of the crop in the face of stress due to lack of rain.

The inoculation technology in the planting furrow allows:
- Protection of inoculated seeds and reduction of bacterial death;
- Elimination of mechanical damage to the seed resulting from inoculation treatments;
- Operational reduction in the treatment of seeds with inoculants;
- Reduction of costs with inoculant losses in eventual seed re-inoculations;
- Application of biological products with efficiency and precision.

The November edition of Revista Cultivar will feature an exclusive article about the technology applied in areas cultivated with rice and soybeans.
