Abstract

Response of sorghum Co.26 to different levels of N and various methods of application was studied in two experiments during 1998 and 1999. Application of the required N in three splits either as 25:50:25 or 50:25:25 at basal, 15 and 30 DAS was found to enhance the grain yield up to 10.08 per cent in 1998 and 8.47 per cent in 1999 over the normal recommended two splits as 50:50 per cent at basal and 30 DAS. 90 kg N ha was found to be optimum.

Keywords: Sorghum, Split application, N levels.
