Development of simple in-vitro protocol for screening low soil nitrogen-efficient maize lines
In order to fast track and compliment conventional maize breeding programme designed for low nitrogen (N) environments, seeds of eight low soil N-tolerant maize lines were sown in the field under no nitrogen and 40 Skin Care Masks kgN/ha for in vivo evaluation with a view to develop simple protocols for screening maize lines for low nitrogen-effici
