Precipitation in variable volumes, which occurred in recent periods over Rio Grande do Sul, reduced the pace of soybean harvesting, which reaches 66% of the cultivated area in the 2023/2024 harvest, with 28% still maturing and 6% of the crops in grain filling. According to the Conjunctural Information, released today by Emater/RS, linked to the State Secretariat for Rural Development (SDR), the occasional heavy rains that occurred over the Central-West region of the State, where it exceeded 250 mm, caused the threshing of pods and the overflow of water courses, directly affecting crops.

In the State, as the harvest progresses to the final third, there is a tendency to reduce crop productivity. This decrease occurs after a peak in yield, in which the best-performing crops expressed a productive potential exceeding 5.400 kg/ha, and is noticed from the beginning of the harvest of later crops, affected by phytosanitary problems, especially Asian rust. However, this situation does not compromise the current harvest, which is considered quite satisfactory. The productivity estimate remains at 3.329 kg/ha.

Corn - the crop harvest increased by 4% compared to the previous period, reaching 82% in the State. The pace of harvesting is still a little slow due to the prioritization of soybean harvesting and rainfall, which made the operation difficult. The prices received by producers have been lower than desired. 

The sometimes unsatisfactory remuneration, coupled with the risks of drought and the high incidence of pests – especially leafhoppers – affect the intention to plant the next harvest, which may suffer a reduction in area. The cultivation area is estimated at 812.795 hectares, and current productivity at 6.464 kg/ha.

Corn silage - both harvesting and silage were hampered by the recurrence of rain since the previous period, preventing activities in the field. It was only possible to carry out new silages from 19/04, when the land and plants reached more adequate levels of humidity. Despite these adverse conditions, the harvest is approaching completion in the North of the State, with larger areas remaining in the South. Projected productivity remains at 35.518 kg/ha.

Beans 1st harvest - the harvest is complete. The harvest was considered satisfactory. An estimated 25.264 hectares are cultivated and 1.930 kg/ha of productivity.

Beans 2st harvest - 13% of the crops are in flowering; 38% in grain filling; 33% in maturation; and 16% were harvested. Management activities were made difficult by high humidity due to rain and the presence of dew. The area cultivated in the 2nd harvest, in the State, is estimated at 19.900 hectares, and the projected productivity is 1.568 kg/ha. 

However, initial harvest results indicate a trend of an 8% increase in relation to initial productivity, but this proportion needs to be confirmed as the harvest progresses.

Rice - the rains delayed the harvest, prolonging the appropriate period for carrying out the operation in some crops that have already been mature for a few weeks, increasing the risk of losses due to repeated wetting and drying cycles, which affect the quality of the grains. 

It is estimated that approximately 70% of the cultivated area has been harvested; 28% is in the maturation phase; and 2% are still in grain filling. The cultivated area in the State is estimated at 900.203 hectares, according to the Rio Grandense do Arroz Institute (Irga). Productivity is estimated at 8.325 kg/ha, according to Emater/RS, but there is a possibility of an increase, depending on the success in harvesting the latest crops.

Vegetable farming

Onion - in the administrative region of Emater/RS of Caxias do Sul, the new onion harvest began with the sowing of super-early varieties. The first seedbeds implemented showed good germination and stand, but there were some problems with tipping over, caused by the rain. The price of the seed depends on the brand and variety, but the most traditional ones grown in the region are being purchased for R$780,00 to R$1.340,00/kg. 

In the sowing system, around two kilos of seeds are sown per hectare, which are subsequently transplanted. Correction of soil acidity and fertility is carried out in planting areas in some areas. Many producers are arranging the costs through Pronaf with financial agents. The expectation of planting intentions for the 2024/2025 harvest is a considerable reduction in the area to be planted.

In the Pelotas region, the onion off-season continues. Producers request funding projects to finance the 2024/2025 harvest with financial agents, as well as negotiate and purchase inputs. The planting of onion seeds for the production of seedlings has already begun, which will be transplanted from June onwards. These seedlings are all grown directly in beds in the ground. A small increase in planted area in the region is estimated, limited to the availability of labor. The price paid to producers for box 3 onion is R$5,75/kg.

Pastures 

On most properties, the established winter pastures have not yet reached the ideal height for the introduction of animals, although some producers have already started to release cattle in these areas. In some regions, recurrent rains caused difficulties in managing annual summer pastures. 

Many areas were severely waterlogged, resulting in excessive uprooting and trampling of plants, which caused significant loss of pasture availability. In native and cultivated perennial pastures, there was good forage production, despite the reduction in temperature and light in recent weeks.

Beekeeping 

In the administrative region of Emater/RS de Bagé, apiaries installed near commercial eucalyptus plantations or native forest and countryside formations in flower are in full swing. In Caxias do Sul, the absence of rain favored the work of bees. However, the low availability of flowers resulted in a reduction in nectar entry into the hives and in the laying of queens. 

In Lajeado, many producers have honey in stock due to low demand in the market, while some are anticipating a possible increase in prices due to the scarcity of the harvest. During this period, harvesting, queen exchange and hive inspections continue. In Passo Fundo, expectations of low honey production persist.
