BEIJING, April 21 (Reuters) - China's soybean imports from the United States rose 43% in March, data showed on Friday, as delays in harvesting in top supplier Brazil prompted buyers to seek more U.S. beans.

The world's top buyer of soybeans imported 4.83 million tonnes of the oilseed from the U.S., versus 3.37 million tonnes a year earlier, General Administration of Customs data showed.

Imports from Brazil fell 42% from the year before to 1.67 million tonnes.

Rain delayed the harvest in key growing regions in Brazil earlier this year.

China's total soybean imports in March came to 6.85 million tonnes, data showed this month, 8% higher than a year earlier.
