ABSTRACT
Field experiments were carried out during 1996-97 and 1997-98 to study the influence of biofertilizer with organic and inorganic sources of nitrogen on quality and yield of rice. Azospirillum plus 50 per cent of the inorganic N recorded more amylose, crude protein content and lower loss of gruel and increased the grain and straw yields. Azospirillum plus 100 per cent of the inorganic N resulted in significantly higher cooking time. Regarding organics sources, daincha incorporation @ 12 t ha-1 recorded higher cooking time, total amylose content, crude protein content and the lowest loss of gruel and also increased the grain and straw yields.
Keywords : Rice, Azospirillum, inorganic nitrogen, daincha, rice grain quality, yield.
