Bt cotton in China fails to reap profit after seven years

...so much that farmers are now having to spray their crops up to 20 times a growing season to control them, according to the study of 481 Chinese farmers in five major cotton-producing provinces. These results should send a very strong signal to researchers and governments that they need to come up with rem...

Researchers develop flood-tolerant California rice

...y-Serres and colleagues plan to work on developing crops that are resistant to multiple stresses. "For example, we'd like to develop rice that is both submergence and salt tolerant," she said, "given that many flood-prone areas are a mixture of fresh and salt water." Besides Bailey-Serres, Takeshi Fukao ...

Genetic snooze button governs timing of spring flowers

...portant agriculturally," he notes. "There are many crops - cabbage, beets - that we don't want to flower. Many of the cultivated varieties we use are never exposed to cold in a typical farmer's field growing season." When that is the case, a cold snap can fool sugar beets, for example, into flowering, a ...

Biologists find regions of rice domestication

...the wild rice." In contrast to rice, other staple crops such as wheat, barley and corn appear to have been domesticated just once in history. Rice is the largest staple crop for human consumption, supplying 20 percent of caloric content for the world. By finding the geographic origins of rice, research...
