Abstract
A field experiment was conducted at Student’s instructional farm, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, Uttar Pradesh during the kharif season 2019 and 2020. “Macro and micro nutrients status in soil under application of vermicompost, Zn and Fe fertilizers in Maize crop.” Two levels of organic manure and four levels each zinc and iron was evaluated under factorial randomized block design with three replications. All the nutrients were applied to maize crop in both seasons and their direct residual response was ascertained to soil were findout. Results indicated that the available nitrogen, phosphorus and potassium status in soil was highly improved with the application of 2.5 tonne vermicompost + 7.5 Kg Zn + 15 Kg Fe ha-1 over all the treatments. The treatment combination M1Zn3Fe3 (2.5 tonne vermicompost + 7.5 Kg Zn + 15 Kg Fe) gave the best result in terms of available nitrogen (221.60 & 220 Kg ha-1), available phosphorus (15.50 & 15.70 Kg ha-1), available potassium (145.15 & 145.24 Kg ha-1), available zinc (0.578 & 0.588 ppm) and available iron (4.30 & 4.36 ppm) across the seasons.
