DEENANATH CO-1: A NEW ANNUAL FODDER GRASS FOR TAMIL NADU

Abstract

In order to develop an annual fodder grass variety to fit into short gaps in the crop rotation, the Pusa-3 Deenanath grass was irradiated with 30 KR gamma rays and from the later generations, a high yielding mutant TNDN-1 was isolated. The culture was tested in different trials and it recorded an average green fodder yield of 44.32 t/ha under irrigated conditions and 23.41 tha under rainfed situations. It can be cut at 60-65 days and it has high crude protein (9.06%), crude fat (2.55%) and low crude fibre (28.95% ). The variety was released as Co-1 for general cultivation in Tamil Nadu.
