Abstract

A field experiment was carried out during rabi 2004 and summer 2005 at Tamil Nadu Agricultural University, Coimbatore to assess the influence of intercropping and nitrogen levels on ratoon ratio and ratoon index of multicut fodder sorghum varieties. Harasona variety registered higher ratoon ratio and index. Sole sorghum gave maximum ratoon ratio and ratoon index. Application of 60 kg N/ha after cutting resulted in higher ratoon ratio and index but it was comparable with that of application of 45 kg N/ha.
