2022/23 Safrinha Corn Harvest Starting In Parana

Farmers in the southern Brazilian state of Parana have started harvesting their 2022/23 safrinha corn. The early harvest pace is less than 1% and it is being slowed by wet weather. The Department of Rural Economics reported that as of earlier this week, the safrinha corn was 1% in vegetative development, 21% pollinating, 69% filling grain, and 9% mature. The corn is rated 2% poor, 14% average, and 84% good.

The corn in the southern and western regions of the state is the most mature, while the corn in the northern parts of the state is the least mature.

In the region of Londrina in northern Parana, wet weather during the soybean harvest delayed the planting of the safrinha corn by approximately two weeks. After the safrinha corn was planted, the weather turned dryer, negatively impacting the corn development. According to the director of the Rural Union of Londrina, safrinha corn yields are normally in the range of 100 to 120 sacks per hectare (95 to 114 bu/ac), but this year the yields should be in the range of 70 to 80 sacks per hectare (67 to 76 bu/ac).

Over the last several weeks, rainfall has returned to northern Parana which should help the later developing corn, but the crop needs to stay frost-free for two more months to insure its full yield potential.
