Abstract

A field experiment was conducted during winter season of 2016–17 and 2017–18 on loam soil at Kulbhashkar Ashram P. G. College Farm of Allahabad to study the interaction effect of phosphorus (0, 40, 60 and 80 kg P2O5/ha) and sulphur application (0, 30 and 60 kg S/ha) on yield attributing characters, yield and N uptake of lentil. All the growth attributing characters, except plant height, increased up to 80 kg P2O5/ha application, but significant increase was noticed up to 60 kg phosphorus only. Likewise phosphorus, sulphur application also improved growth characters up to highest level of sulphur application (60 kg/ha) but significant increase was noted only up to 30 kg sulphur/ha, except total number of branches per plant during 1st year. Yield and yield attributing characters of lentil increased with every incremental doses of phosphorus and sulphur both, up to the highest level of phosphorus and sulphur used but significant increase was registered at 60 kg P2O5/ha and 30 kg S/ha, either of the years. Phosphorus application increased nitrogen uptake significantly up to 60 kg P2O5/ha in grain, while in straw it increased significantly up to 80 kg P2O5/ha. Sulphur application increased nitrogen uptake significantly up to its highest dose in grain and straw both during both the years of experimentation.
