Comparative performance of Azotobacter chroococcum, Glucanobacter diazotrophicus tested both at 50 per cent and 75 percent recommended N showed that Glucanobacter diazotrophicus was more effective than Azotobacter chroococcum in improving the tuber yield and nutrient uptake. The total tuber yield per plot (8.53 kg), per hectare (38.61 tons) and nutrient uptake in plants (135.14-N, 28.96-P, 49.04-K, kg/ha) was maximum in combined inoculation of microbial inoculants viz., Azotobacter chroococcum,

The combined effect of microbial inoculants helps in better uptake of nutrients, improved yields and also saves 25% of application of recommended dose of chemical fertilizers. key words: Beetroot, Nutrient uptake, Yield, Microbial inoculants, Nutrient management, Beneficial microorganisms. rEFErENCEs showed a possible saving of 25 per cent N and P chemical fertilizers with maximum yield compare to that of 100 % recommended NPK.
