Effect of season, spacing and phosphorus on seed production Sesbania species

摘要

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 Phosphoru fertilisation and plant density on seed production of green manure species such as Sesbania rostrato, Saculeata and S. speciosa. From this study it was concluded that growing S. rostratd or Saculeata during summer with a spacing of 120 X 15 cm under a phosphorus level of 50 kg per ha can be considered as optimum management techniques for incrcascd quality seed yield.
