Brazil will become the world's largest soybean producer in 2014, Brazilian President Dilma Rousseff said on Monday.

"Brazil will become the world's leading soybean producer, showing the strength of our agricultural sector, which is important to our development, the domestic supply and exports," Rousseff said.

According to Brazil's national supply company Conab, the total grain yield will reach 193 million tons this year, of which 90 million tons will be soybeans, outnumbering the soybean output of the United States -- currently the largest producer.

The soybean will remain Brazil's largest crop, with its share in the total grain production rising from 43 percent to 47 percent, Conab forecast.

Rousseff said Brazil has committed to boosting its agricultural productivity as its grain production increased by more than two-fold in the past two decades, while the arable land grew only by 41 percent during the same period.
