Wheat reaches an average productivity of 3,5 tons per hectare in RS

Emater/RS-Ascar carried out the third estimate of the 2022 winter harvest, with quantitative data obtained by the 497 municipal offices in Rio Grande do Sul, after the end of the harvest.

The wheat cultivation area reached 1.474.364 hectares, around 20% higher than the previous year. The productivity obtained was evaluated at 3.508 kg/ha, 21,61% higher.

Soybean situation

The projected area for the 2022/23 harvest is 6.568.607 hectares. Productivity is 3.131 kg/ha. There was rain at two different times: the first on 27/12 and the second on 01/01.

Rainfall was in variable volumes, poorly distributed and did not reach all production areas. This prevented sowing from being completed in some regions. The implementation of the culture reached 96% of the initially planned area.

In phytosanitary terms, predominantly dry weather is favorable to the emergence of mites. Producers carry out monitoring and control.

Corn situation

The estimated corn cultivation area for the 2022/23 harvest is 831.786 hectares. The two rain events (27/12; 01/01), although irregular and poorly distributed, favored the resumption of sowing where moisture in the soil was replenished. However, the evolution was only 1%, reaching 92% implemented.

The water deficit persists in most of the state. There is consolidation of productivity losses. The indices are different, even within the same region. Only in the Northeast does productivity remain close to what was initially projected.

In phytosanitary terms, we carried out measures to control invasive plants. Fall armyworm and corn leafhopper remain monitored and chemically controlled.

Rice situation

The estimated rice area by IRGA is 862.498 hectares. Productivity was 8.226 kg/ha. The high availability of solar radiation favored crops in the vegetative development phase.

On the other hand, the rise in temperatures in the western half of the state, with records close to 40°C (31/12; 01/01), could result in sterility of spikelets in crops that are between the pre-flowering and emission phases. of panicles and flowering.

In general, the crops already have irrigation established; development is great, health is good, and there are no problems with pests. The productive potential was maintained in crops that had an adequate plant stand and without major limitations regarding the availability of water for irrigation.
