A Studies on yield, quality and availability of N and P of soil in autumn cane as influenced by P levels and P.S.B. inoculation in legume inter-cropping systems

Field trials were carried out to test the efficiency of phosphorus solubilizing bacteria (P.S.B.) in cane + pea inter-cropping systems on solubility of applied phosphorus during autumn seasons in soil. The treatment 80 kg P₂0₅ ha⁻¹ produced more number of shoots, millable canes and recorded significantly higher cane yield (92.74t ha⁻¹) than the 0 kg P₂0₅ ha⁻¹ during both the years. Cane + pea (inoculated with Rhizobium) + P.S.B. @ 6 kg ha⁻¹ gave significantly higher cane yield (92.61t ha⁻¹) than the cane alone without P.S.B. during both the years. C.C.S. per cent were not affected significantly due to various P levels and inter-cropping systems. However, both factors showed positive influence on availability of N and P by cane at harvest.
