Field Evaluation of Consortium ofAzospirillum, PSB and AM Fungus on Yield Parameters of Direct Seeded Rice

摘要

A field experiment was conducted to know the influence of efficient strains ofAzospirillum, phos-fate solubilizing bacteria (PSB) and AM fungus on yield parameters of direct seeded rice (DSR). Direct seeded rice variety gangavati sona was selected andseeds were treated with 3 efficient strains of Azospirillum brasilense (ADSR-9), PSB {Bacillus megatarium var phosphaticum) and AM fungi Glomus sp. (MDSR-3). The treatment T,0 (Azospirillum X PSB XAMF + 75% N + 75% P + 100% K) recorded significantly higher 100 seed weight (2.50 g), number of seeds per panicle (193.31), grain yield (7,640 kg ha~(-1)) and stover yield (11.219 kg ha~(-1)) of the DSR compared to individual and dual biofertilizer inoculated treatments and controls.
