Abstract

                                Two independent sets of field experiments were conducted for two consecutive seasons during 1993 and 1994 at Wetland Farm of Tamil Nadu Agricultural University. Coimbatore,to determine the optimum time of sowing.influence of Phosphorus fertilisation and plant density on seed production of green manure species such as Seshania rostrata Saculeata and S.speciosa. From this study it was concluded that growing S.rostrata of S.aculeata during summer with a spacing of 120 X 15cm under a phosphorus level of 50kg per ha can be considered as optimum management techniques for increased quality seed yield.

Key words : Sesbania species. Seasonal influence, Seed production, Spacing, Phosphorus
