Effect of biofertillizers [Azatobacter and Phosphorus Solubilizing Bacteria (PSB)] and their combinations on germination and survival of Brassica campestris

The investigation was carried out on Brassica campestris L., two varieties (YS-66 and K-88) cultivated with the treatment of two biofertillizers Azatobacter and phosphorus solubilizing bacteria (PSB). In varieties YS-66 and K-88, effect of Azatobacter 15g inoculation showed 97 ? 1.1 and 97 ? 1.2% germination with survival of 99 ? 1.2 and 98 ? 1.2% respectively. PSB 15g inoculation showed 98 ? 1.2 and 99 ? 1.1% germination with survival of 96 ? 1.1 and 97 ? 1.2% respectively. Azatobacter +PSB, 15g+15g inoculation showed 98 ? 1.2 and 99 ? 1.2 % germination with survival of 98 ? 1.1 and 98 ? 1.1% respectively . Control seeds of both varieties showed 96 ? 1.2 % germination and 94 ? 1.2 survival respectively.
