Abstract
A field experiment was conducted during the Rabi seasons of 2017-18 and 2018-19 at the Studentsâ Instructional Farm, Department of Agronomy, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur (U.P.), to evaluate the effect of different organic and inorganic fertilizers on nutrient content and uptake of chickpea (Cicer arietinum L.) variety KWR-108. The soil was sandy loam, slightly alkaline (pH 7.70), low in available nitrogen and organic carbon, and medium in phosphorus, potassium, zinc, and boron. The experiment was laid out in Split Plot Design with three fertility levels and seven micronutrient and biofertilizer treatments. Results revealed that 100% RDF (20:60:20 NPK kg/ha) and 50% RDF + vermicompost recorded significantly higher nutrient content, uptake, and yield attributes over 50% RDF + FYM. Among micronutrient treatments, PSB + Zn + Bo and PSB + Bo showed superior performance. Integrated application improved soil fertility and enhanced chickpea productivity sustainably.
