A field experiment was conducted during rabi seasons of 2008–2009 and 2009–10 to study the effect of potassium and cobalt application on growth, yield and nutrient uptake in lentil. The results revealed that the plant height, branches/plant, dry matter accumulation, pods per plant, test weight, grain and straw yield of lentil and protein content increased significantly up to 90 kg K₂O ha⁻¹. However, yields at tributes and yield at 60 and 90 kg K₂O ha⁻¹ were statistically on par. On the other hand, growth and yield attributes and yield (grain and straw) increased up to 4 kg Co ha⁻¹ and thereafter, declined at 8 kg Co ha⁻¹. The protein content in lentil grain improved appreciably when crop was fertilized with 90 kg K₂O and 8 kg Co ha⁻¹ over respective controls. The uptake of K and Co in lentil grain and straw increased significantly with increasing levels of K and Co. The uptake of N and P by lentil grain and straw increased with graded levels of cobalt up to 4 kg ha⁻¹. On the other hand, there wasa gradual decrease in S uptake with cobalt levels. Potassium application tended to increase the uptake of N, P and S by the crop significantly over control.
