Moisture within the soil profile was good; planting started mid May and continued to mid June as rains delayed the summer crops harvest. Short cycle varieties were planted until end of July.
Tillering occurred under good moisture but with high temperatures that induced a rapid growth.
Late frosts occurred in the reproductive stage and affected long cycle varieties, mainly. On the other hand, drought and high temperatures negatively affected short cycle varieties. The combination of no rain and high temperatures (up to 35°C) accelerated maturity and affected grain final weight, resulting in plots in regular conditions by the end of cycle.
Aphids and trips incidence was severe in some cases. No significant damage from foliar diseases was observed.
Harvest started beginning of October and extended until the end of the month, with some interruptions caused by rain, early in November. Early planted plots, exception made of those affected by late frost, gave the best yields. Late planted plots suffered a marked drop in yields due to lack of moisture.
43,180 ha were harvested; total production was 39,966 tons with an average yield of 930 kg/ha. Yields ranged from 400 to 1,700 kg/ha, which correspond to historical values. Drought and frosts led to the loss of 2,300 ha; a small fraction was slightly affected by hail.
