Abstract:

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, Glucanobacter diazotrophicus, Bacillus megaterium and Trichoderma harzianum, with 75 per cent N, P with full dose of K compared to control plants ( FYM alone T₁₄). 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.
