Abstract:
A field experiment was carried out during the winter (Rabi) season of 2022-23, at the Experimental field, Department of Soil Science and Agricultural Chemistry, AKS University, Satna (M.P.) to find out the effect of Potassium in Relation to Yield and uptake of Nutrients in Chickpea Crop (Cicer arietinum L.).The experiment consisted of ten treatments i.e., T₁ (Control), T₂ (5 Kg K₂O /ha), T₃ (15 Kg K₂O/ha), T₄ (25 Kg K₂O/ha), T₅ (35 Kg K₂O/ha), T₆ (45 Kg K₂O/ha), T₇ (55 Kg K₂O/ha), T₈ (65 Kg K₂O/ha), T₉ (75 Kg K₂O/ha), T₁₀ (85 Kg K₂O/ha). The experiment was laid out in a Randomized block design with three replications. The results revealed that yield attributes and yield were significantly influenced by different potassium levels. There was a marked increase in number of pods per plant (31.00), number of seed per pod (1.80), 1000 seed weight (236.67 g) and seed yield (18.09 q/ha) with the application of 85 kg K/ha. Similarly, plots fertilized with 85 kg K/ha had higher uptake of N, P, K and Zn by both seed and stover of chickpea.
