In the campaign 2011/12 enough humidity was alternated for the sowing with a water deficit in some areas and a very good grain filling. The performances in general were from good to very good, although they did not achieve the high values of the campaign 2010/11.
Sowing was possible to be done in the proper dates since there were no significant rains between June and August. With proper temperature and soil water, the wheat crop developed normally, with a good tilling and with no frosts reducing the foliar surface. There were late frosts by the end of October, but in general they did not produce significant damages. In October, the temperatures were normal, but the scarce rains affected mainly the crop in superficial soils by the end of the month. Hail affected the location Gonzalez Chaves and part of the adjacent locations.
As from November 4, the rains were abundant and the soil profile water was recovered (190 mm in November) in the central-western area of the Sub-region IV. All the Sub-region was benefited with higher rainfalls in November allowing a very good grain filling stage and obtaining values above the historical average. The total rains from June to December were an 8% higher than the normal and a 110% higher in the grain filling stage (November). The ear-maturity period length was normal allowing the harvest to be in the last week of December. In November, the average temperatures were of more than 1.4º C lower than the average of the last 10 years with only 2 days of more than 30º C. The abundant rains produced a significant increase in the Weight of 1000 Grains and in the Hectoliter Weight (PH), which contributed to good produces and a good commercial quality.
Foliar diseases were not significant and only the highly susceptible cultivars had significant values of leaf rust to evidence a decrease in the produce and the commercial quality (PH). There was a differential in the produce average in favor of the treatments with fungicide, although it was not important.
The yields of the zone, due to the good weather conditions ranged between 3,000 and 6,000 kg/ha. The problems in the commercial quality due to the low percentage of proteins in the grain were given when the fertilization was not high enough for the obtained yields.
