Summary In Brazil, high-yield soybean [ Glycine Max (L). Merrill] – corn ( Zea mays L.) double cropping system might be nitrogen (N)-limited and additional N fertilization can beneficial. Early application of in reduces the symbiotic fixation (SNF) efficiency and/or establishment. One alternative to avoid SNF impairment is apply between beginning pod (R3) seed-fill (R5) stages through use contr...

Estimation of the rate genetic gain over time allows quantification breeding progress. Here we report on grain yield and zinc (Zn) concentration increase 11 yr targeted wheat (Triticum aestivum L.) biofortification at International Maize Wheat Improvement Center (CIMMYT). Data from trials evaluated across multiple locations in South Asia beyond showed that average annual increases potential ?1....
