New agricultural technologies and investments in infrastructure have enabled Brazil to triple its production of grains over the past 20 years, President Dilma Rousseff emphasized on Tuesday.

"Grain production grew 221 percent and the area planted grew by only 41 percent," said the head of state at a ceremony to mark the beginning of the grain harvest.

"That is (an injection of) productivity into the vein and it's what we're seeking for all the other areas of the country," she said.

The event, held in the western city of Lucas de Rio Verde, coincided with the announcement that Brazil in 2013-2014 will achieve a record harvest of 193.6 million tons of grain, up 3.6 percent from 2012-2013.

Forecasts indicate that Brazil this year may replace the United States as the world's largest soybean producer and cement its position as one of the largest producers of corn.

Government financing for agricultural production skyrocketed from 27 billion reais ($11.25 billion) in 2002-2003 to 136 billion reais ($56.66 billion) for the current harvest, Rousseff said.

"The country needed a clear agricultural policy. When we (the Workers Party) came into the government in 2003, agricultural policy had big limitations. First, the availability of credit and, second, high interest rates," she said.

The president recalled that the government last year launched a plan that forecasts annual investments of some $2.08 billion to build silos, which are intended to minimize post-harvest losses caused by the lack of sufficient storage capacity.

She also emphasized the bids launched by the government to modernize highways and ports, whereby the transport of grains to the ports will be facilitated. EFE
