SUBREGION I

BACKGROUND FOR THE CROP

        

Planting was completed from late May to the first fortnight in July. Soil moisture at the time of planting was good to average. Crop developed slowly in some fields until rains came late in June. Rains came back in the first fortnight in August and improved wheat growth. Unfortunately though, some fields suffered heavy rains that washed the nutrients away.

Plant emergence and stand were adequate and crop developed properly in the fields. Farmers used less seed technology and did not fertilize much this growing season. Yellow spot and orange rust were detected with variable intensities, depending on the area and wheat variety. The most affected fields were treated.

It is estimated that variable weather conditions at grain filling partially affected yields and grain quality. Cloudy days, temperatures below average and heavy rains at late phases of grain filling negatively impacted on quality and led to starchy, low-protein wheat.

Yields were uneven and in direct relation with weather conditions and applied technology. However, overall yields were below expectations. As harvest progressed, there was a gradual drop in yield average. Yields ranged from 2,300 to 2,900 kg/h, with minimums of 1,000/1,500 kg/h and maximums of 3,500/4,000 kg/h.

Grain commercial quality also presented different test weight values and some white belly grains. Protein contents were, in most cases, below basis, due to the little N fertilization applied.
