Abstract: A study was carried out in maize to find the biochar effect on plant nutrient status and plant uptake with seven treatments viz., control (no fertilizers) (T1), RDF (T2), RDF+Azophos (T3), 75% RDF+biochar @ 5 t ha-1 (T4),75% RDF+biochar @ 5 t ha-1+Azophos (T5), 75% RDF+FYM @ 5 t ha-1 (T6), 75% RDF+FYM @ 5 t ha-1+ Azophos (T7) in Randomised Block Design (RBD). The plants supplied with 100 % RDF showed highest nutrient status and is at par with the treatments supplied with biochar. Plant uptake of NPK was observed maximum in the treatments supplied with RDF and was at par with treatments supplied with biochar and FYM. Iron and zinc contents in sweet corn at knee high, tasseling, in grain and stover at harvest were not significantly influenced by the treatments, whereas uptake of micronutrients was significantly influenced by imposed treatments.
