SUBREGION II SOUTH

BACKGROUND FOR THE CROP

 

The sowed area in the North Center region of Buenos Aires province in some areas had a slight decrease as regards the historical average; the surface was occupied with other winter crops, especially barley. Such lower acreage was offset by increasing planted elsewhere and good yields per hectare, which in many cases surpassed the expectations, taking into account that the climate conditions during their cycle were not so favorable.

The sowing dates concentrated in June and July, and in some cases in August. During the cultivation cycle (May-November), in the zone of Pergamino, there was a deficit of rains as regards the historical average (1910-2010) of 186 mm, but the good distribution of rains produced in the critical moments of the crop did not affect their development.

In most of the cases, the fields were fertilized with nitrogen and phosphor and in some cases also with sulfur.

The minimum temperatures during the tilliering were not considered unfavorable. During the first week of September, they varied between -3.4º C and -7.5º C, favoring the varieties with longer cycle, with cold needs. During blossom and in grain milk stage there were temperatures under zero on October 03 (-4,5º C), October 27 (-2,7º C) and October 31 (-1,8º C). The maximum high temperatures during the grain filling varied between the 33º C to 38º C from November 05 to 10 and November 18 to 21. It is considered that they did not produce any shrunken grains. The high solar radiation favored even more the metabolic processes of the plant for the grain filling.

Among the insects, the greenbug aphid and the grain aphid were present with more intensity, and chemical treatments were needed.

The general level of diseases was low, with a higher frequency of the leaf rust (Puccinia tritici Rob) and yellow spot (Drechslera tritici repentis). The ear fusariosis only occurred in specific cases with a low intensity attack. Harvest was advanced a couple of days and it developed in excellent conditions, with no rains and very low environmental humidity. Yields were very good, with excellent hectoliter weights and weight of 1,000 grains. The performances per surface unit did not equal those of the agricultural campaign 2010/2011, but they surpassed the historical average. There were fields with significant surface that produced between 5,000 and 6,500 Kg/ha.
