Abstract

A superior selection of Seshania rostrata (Brem ohra) (Sr. S1) was developed from the year 1986 to 1996 at the Paddy Breeding Station, Tamil Nadu Agricultural University, Coimbatore." The over all mean performance in station, multilocation trials and on-farm trials indicated that thes culture has recorded an average yield of 24.5 t/ha as against 21.8 t/ha recorded by Saculeata. The yield increase was 12.4 per cent. It has also recorded higher mean number of nodules (205) than Saculeata with 210.6 per cent increase. It has high total nitrogen (3.74%) while the other Sesbanin species viz, S.specioso and S.aculeatu recorded only 2.36 and 2.38 per cent respectively. It has low CN ratio of 5:2 and high nitrogenese activities.
