SUBREGION V NORTH

BACKGROUND FOR THE CROP

The sown surface was significantly broader than that of 2009/2010 campaign mainly due to a better supply and accumulation of soil water, but the uncertainty as regards commercialization lead the producers, in some cases, to sow smaller surfaces and others not to sow.

The sow was mainly done during May, but there were some specific zones where the sow was done by the end of April.

Although, in general, there were no major problems, in some areas there was a slow growing and leaf spotting due to the lack of soil humidity, and there were lots with small plants, plants lots and lots where the future expectations lead the producers to destine the plants to animal consumption.

The growing stages were irregular, since there were late frosts that affected in different proportions the grain filling.

The sanitary status of the crops was good in general, except for some specific cases of yellow spot and leaf rust. As regards the occurrence of plagues during the crops development, there were aphids and some mites.

At the grain filling stage, in some lots, the crops were snatched, which damaged the grains in the superior part of the ear, due to the presence of high temperatures.

The Department that outstood due to its high performance was General San Martín, with average values higher than 3000 kg/ha. Such high levels were also registered in the departments of San Justo, Río Primero, Río Segundo and Roque Sáenz Peña. The lots form the dry lands had performances of around 1000 and 3000 kg/ha. The lots with irrigation had performances of between 3000 and 5000 kg/ha. Such high performances influenced the lower percentages of proteins and gluten.
