A Field experiment was conducted at Zonal Agricultural and Horticultural Research Station, Shivamogga, Karnataka to see the residual effect of biochar and FYM on productivity of succeeding green gram crop during Kharif 2018 after harvest of summer aerobic rice crop. Results revealed that the growth and yield attributing characters of green gram viz., plant height and number of leaves per plant, number of pods bearing auxiliary branches per plant, pod length, number of pods per plant, and number of seeds per pod were significantly influenced by residual effect applied biochar and FYM with RDF at different growth stages. However, higher growth parameters were observed in treatment contains CS-biochar 8 t ha-1 and 10 t ha-1FYM with RDF (T16) compared to RDF alone and absolute control. Green gram seed and stover yields were significantly influenced by the residual levels of biochar and FYM combinations. Higher seed and stover yield (871.00 and 1708 kg ha-1) was recorded in CS-biochar @ 8t ha- 1 + FYM 10 t ha-1 + RDF (T16) treatment and which showed the percentage efficiency of 4.72 to 14.30 per cent and 4.90 to 14.63 per cent increase in seed and stover yield of a green gram as compared to the treatment, T4 (RDF + FYM 10 t ha-1). Similarly primary, secondary and micronutrients uptake by green gram plant at harvest varied significantly due to the residual levels of biochar and FYM with RDF. However, the highest content and uptake of these nutrients was observed in treatment, T16 (CS-biochar @ 8t ha- 1 + FYM 10 t ha-1 + RDF) as compared to other treatments.
