According to the Brazilian National Supply Company (Conab) published in its Agricultural Monitoring Bulletin for April, in the accumulated rainfall recorded between April 1 and April 21, it is observed that the rainfall occurred, more significantly, in the North region from the country. Also covering Maranhão and part of Mato Grosso, where cotton and second crop corn were favored. The lowest levels of precipitation occurred in Mato Grosso do Sul, in parts of São Paulo and Paraná, mainly restricting the crops of beans and corn second crop in reproductive stages. On the other hand, the few rains favored the advance in the harvest of soybeans and maize first crop.

The daily average of water storage between April 1st and 21st was below what was necessary for the full development of crops, which is behind, in relation to the previous harvest, in the states above. This delay, especially for second crop corn, is still a reflection of the soybean planting and harvesting calendar postponed by the delay in the rains at the beginning of this harvest.

Through the storage maps, the bulletin identifies that at each interval of seven days, the humidity in the soil decreased during the monitoring period. However, the impact on crop development has yet to be measured, as there may be recovery depending on the stage in which most crops are located.

In the panorama of the first harvest, the harvest is advancing in the producing states.

Goiás: Harvest began during the last few weeks and has intensified considerably, reaching about 60% of the total harvested area by the second ten-day period in April. The yields obtained have been satisfactory, however, the reduction in the planted area had an impact on crop forecasts, and should present a production lower than that predicted in the first surveys of the 2019/20 crop.

Minas Gerais: Harvest reaching 3/4 of the total sown area, with the rest of the crops already in the maturation stage. The forecast is for an increase in final production compared to 2019/20, particularly due to the increase in planted area.

São Paulo: There are few areas left to be harvested in the state and it is estimated that production will be lower compared to the previous harvest. There was a reduction in the planted area this season, also impacting the initially estimated result.

Paraná: There is a delay in the culture cycle compared to the region's historical average. The drought that occurred at the beginning of the harvest postponed the sowing cycle. Currently, the harvest is in its final stage, occurring intensely, favored, even, by the dry climate recorded recently. In general, even with an increase in the planted area this season, it is estimated a reduction in final production, compared to 2019/20, due to climatic fluctuations throughout the development of crops.

Santa Catarina: Harvesting in the final stage, with few areas left to be harvested in the state. The drought that occurred between September and October 2020, in addition to the high incidence of leafhopper attacks in some regions reduced the productive potential of the crop. Thus, even with an increase in the sown area, production will remain below the previous harvest.

Rio Grande do Sul: Harvest operations have progressed, but at a less intense pace, due to the prioritization of efforts to harvest soybeans. Even so, about 77% of the total area planted with corn in the state had already been harvested by the third week of April. Crops that were sown earlier, especially in the northwest of the state, were more affected by the drought at the beginning of the cycle and showed considerable losses. Overall, average productivity is higher than the previous season, 2019/2020, but lower than the 2018/1019 crop, considered a normal crop for the state.

Bahia: Harvest operations are in progress. In the Center South and Center North of the state, the development of crops was hampered due to the water deficit that lasted until the end of January and with this, the records are of significant losses in productivity. In the Far West, the climatic conditions were better, yielding more vigorous crops. Overall, the average state productivity is expected to be lower than that recorded in 2019/20, but due to the increase in area, higher production is estimated

In the off-season or second crop, there are impacts of the climate and attacks by pests such as leafhoppers. It is not yet possible to measure the losses due to the delay in the planting window in the two largest producers, Mato Grosso and Paraná. Check out the panorama:

Mato Grosso: Sowing completed, confirming the estimated growth in the planted area compared to the previous harvest. Almost 40% of the crops were planted outside the period considered ideal for planting the crop. Thus, there is a concern with climatic conditions during the cycle, especially in relation to the incidence of rain, since this season is usually of low rainfall in the Midwest.

Paraná: Sowing is practically finished. So far, most of the crops already implanted are in regular and good conditions, however, the maintenance of low humidity in the soils can impact the development of the crop.

Mato Grosso do Sul: Planting completed, but in unfavorable conditions, especially in relation to water availability in the soil. The scarcity of rainfall has worried producers, both for the emergence of plants and for their development.
