Objectives
|
Drs. Y.G. Yanni and F.B. Dazzo proposed to continue collaborative research in agricultural biotechnology biofertilizer development at Egypt and USA. Theirgoal was to increase cereal crop productvity with less dependence on N-fertilizer usage byy optimizing their beneficial association with growth-promoting rhizobia. Their previously work showed that (1) diverse populations of R. leguminozarum bv. trifolii naturally conlonize the root interior of rice in Nile Delta fields where rice/clover rotation is establish several centuries ago; (2) certainn rhizobia promote rice growth resulting in improved root architecture and enhanced plant nutrient uptake, and increase grain yield and agronomic N-fertilizer use efficiency in field inoculation trials, and (3) rhizobia also colonize the root interior of wheat grown in Egypt
