The result of field trial on response of lentil to application of phosphorus, zinc and their liquid biofertilizers showed synergistic effect on growth, yield attributes and yield of lentil. The results emerged out clearly indicated that use of 50% RD phosphorus + 12.5 kg ZnSO₄ + Biophos @ 5 ml kg^-1+ Biozinc @ 5 ml kg^-1 was found to be effective and significantly increase the growth and yield attributes of lentil crop viz. Plant height (25.97 cm), Chlorophyll content (3.05 mg g^-1), number of nodules plant^-1 (30.62), Fresh weight of nodules (37.04 mg plant^-1), number of pods plant^-1 (199.11), and number of seed pod^-1 (1.71), seed yield (2337 kg ha^-1) and stover yield (4630 kg ha^-1), biological yield (6967 kg ha^-1) were also obtained. Among the treatments, application of Biophos @ 5 ml kg^-1+ Biozinc @ 5 ml kg^-1 combination along with 50% RD phosphorus + 12.5 kg ZnSO₄ inoculation showed superiority over all the treatments for improving growth, yield attributes and yield of lentil. Thus, it can be concluded that the application of Biophos @ 5 ml kg^-1+ Biozinc @ 5 ml kg^-1 combination along with 50% RD phosphorus + 12.5 kg ZnSO₄ recorded statistically superior in growth, yield attributes and yield of lentil as compared to alone application of recommended dose of phosphorus.
