| Abstract | ||
| A field experiment was carried out at the center of the guiding and training agricultural Al-Mahnawia – Babel during the autumn season 2103 and autumn 2014 to evaluation the parents and it's hybrids the production by half diallel crosses under two levels of nitrogen fertilizer (160-320) kg N/H and selected the superior hybrids. At autumn season 2013 a half diallel crosses was done among the seven pure inbred of maize (HS-R153 , IK8 , ZP 707 , ZP 607 , D K , SY 7) using Graffing method 2 fixed method twenty-one hybrids were collected in the end of the season. During autumn 2014 a comparison experiment was done with split plot arrangement with random complete block design with three replication was used including two levels of nitrogen fertilizer (160-320) kg N/H assigned in the main plots and the seven inbreds lines of maize and it's crosses were assigned in the sub plots to estimation of mid all traits and heterosis under two nitrogen levels for all qualities studied: leaf area, number of ears , number of grains / ear , 500 grains weight, grain yield, total plant uptake nitrogen. | ||
