Arcadia Biosciences, Inc., an agricultural technology company that develops and commercializes plant traits and products that improve farm economics and benefit the environment and human health, has joined with the International Center for Tropical Agriculture (CIAT).

They have jointly announced the completion of a third year of field trials of nitrogen-use efficient (NUE) rice. CIAT has been testing the rice at the Center’s research fields in Colombia. For the third year in a row, rice lines with Arcadia’s NUE trait produced significant yield increases relative to conventional varieties.

Over the 3 years of field trials, the leading rice line with Arcadia’s NUE trait out-yielded control lines by an average of 27%. The trials included both irrigated lowland and rainfed upland locations. In the third year trial at 50% of normal applied nitrogen fertilizer, the leading NUE rice line out-produced the control line by 33%. The previous two years’ trials showed yield increases of 22 and 30% respectively.
