RESPONSE OF FODDER OAT (AVENA SATIVA L.) TO METHODS OF AZOTOBACTER INOCULATION UNDER VARIOUS LEVELS OF NITROGEN

摘要

A field investigation was carried out during 1993-94 and 1994-95 to study the response of fodder oat (Avena Saliva L.) to 3 methods of inoculation (without inoculation, seed inoculation and soil inoculation) and 4 levels of nitrogen (0, 40, 60 and 80kg N ha~(-1)). Inoculation with Azotohacter either of the methods significantly increased the plant height, number of leaves/plant, tillers/plant, green fodder, dry matter and crude protein yields. The crop responded significantly upto 80 kg N ha~(-1) for green fodder, dry matter and crude protein yields. Interaction between inoculation methods and N levels was found significant. Inoculation of seed with Azotobacter receiving moderate levels of nitrogen (60 kg N ha~(-1)) gives similar yields to that recorded under higher dose of 80 kg ha~(-1) alone.
