Summary
Inoculation with root-nodule bacteria had favourable influence on N-uptake and yield of wheat. Since waterlogged root region of rice permits higher nitrogenase activity a pot culture experiment was conducted using same nine strains of rhizobia,Azotobacter chroococcum and bluegreen algae as inoculants.R. leguminosarum in combination with 50 kg N ha−1;R. japonicum and a strain of rhizobium isolated from moong bean increased the yield of paddy cv. Pusa-33. On the other hand an adverse effect of bacterial inoculation and of applied N was observed in case of Azotobacter, and rhizobia isolated from green gram, cicer, soyabean and clover.
The importance of plant type, growth conditions and application of inorganic N in determining the success of plant-rhizobial associations is emphasised.
