Dual-purpose production of forage and seeds in maize by detopping and defoliation

Maize is one of the most productive crops whose seeds are used in poultry sector as main ingredients their diet. It also important forage for ruminants silage. The aim this research was to assess effect defoliation and detopping on dual-purpose maize production field (Kermanshah, Iran, Mediterranean climate conditions) laboratory experiments. study included a control (intact plant), removal leaves at top ear, under all leaves, stem including ear. In experiment, germination traits were assessed obtained from mother plants experiment. experiments conducted with randomized complete block design completely design. data analyzed using general linear model. ear produced an increased seed number per row compared Intact (control) defoliated had higher 100-seed weight than other treatments. There no difference between yield. Removal lower percentage (83%), radicle length (11.3 cm), vigor results show that can be cultivated crop production.
