A two year field experiment was conducted during 2023-24 and 2024-25 at Krishi Vigyan Kendra, Jamtara to study the impact of maize based cropping system on nutrient uptake and content by maize crop. Adopted the all crop management practice s and availability of input are sufficient in research farm. The experiment was consisted of 9 treatments T1-Maize - fallow, T2-Maize - wheat, T3-Maize (Green cob) - toria - wheat, T4-Maize (Green cob) - toria - chickpea, T5-Maize - pea - Greengram, T6-Maize - linseed - Greengram, T7-Maize - lentil - Greengram, T8-Maize - chickpea - Greengram and T9-Maize - potato - Greengram with three times replications in Randomized Block Design. The highest N content in maize grain was recorded 1.33% and 1.23% during 2023-24 and 2024-2025 under Maize - Chickpea- Greengram and Maize - Pea- Greengram respectively, P content in grain also highest (0.210% and 0.199%) in Maize - Pea- Greengram cropping system while K content in both grain and stover was highest (0.296% and 0.895%) in Maize - Chickpea - Greengram during 1 st year. The pooled NPK uptake of grain and stover was significantly increased inclusion of pulses crop in cropping system. The highest N (83.34 and 55.43 kg / ha), P (13.30 and 7.72 kg / ha) and K (18.42 and 89.73 kg / ha) grain and stover respectively recorded under treatment T-5 (Maize - Pea- Greengram) cropping system.
