SUBREGION II SOUTH

BACKGROUND FOR THE CROP

        

Water accumulation in the soil profile before planting was excellent. Water ponded in some areas in the fall months. Intermediate and short cycle varieties were planted in June and July.
Fertilization management was better: phosphate fertilizers were applied at planting, and nitrogen fertilization was used before planting or at planting/tillering. Early planted seeds set very well thanks to timely rains at the end of May and end of June. Early growth stages developed under adequate moisture levels, especially where the crop was sowed early.
Most plots suffered significant water stress in August, at tillering.  Lack of rains negatively impacted on late planting: growth was not as vigorous, and the crop set more unevenly. The precipitation deficit continued all along September when a more critical growth stage starts.
Flowering was under good rains and consequently, better water supply, but moisture distribution and level were quite irregular. Grain filling was between October 20 and November 20, under low temperatures and mild showers. The number of grains per square meter was very good.
Biotic stresses were represented by strong and early attacks of stripe rust roya (Puccinia striiformis), and leaf rust (Puccinia triticina) and a significant occurrence of the foliar spot complex that had severe consequences on certain cultivars. Weather conditions at flowering favored an attack of stem Fusarium in the center of the subregion. Harvest was under excellent weather conditions. Economic results were good, with an average yield of 40 to 42 q/h, with peaks of 75 to 80 q/h.
Grain commercial quality was very good. Grain filling under cool temperatures resulted in adequate test weights and a proper number of grains per square meter.  Protein content was very good.
