Trigo Argentino

BACKGROUND FOR THE CROP

The 2018/19 wheat season started in May. Moisture build-up ranged from right to regular in the different departments.

This year, water build-up was not good in the different soil profiles. Low temperatures delayed the growth cycle in reproductive stages. Tucuman witnessed soft frosts. Dryland wheat suffered the lack of humidity and was affected by high temperatures in September and October. The development of wheat under irrigation was better. By late October, rains delayed harvest; some grains presented shoots.

Dryland wheat yields in the province of Salta were low but better in areas under irrigation; 8 to 20 q/h and some plots were lost due to water excess. Weather conditions prevented harvest in 30% of the plots in Tucuman. Yields ranged from 400 to 1,200 kg/h. Plots harvested before the storm presented higher yields, even above 18 q/h.
