Abstract:
The present experiment is a part of a long-term experiment based on the effect of crop residue and residual starter zinc. This part of investigation “Vertical distribution of DTPA- c copper in Post-Harvest Soil of Wheat as Influenced by Crop Residue and Residual starter Zinc”. Distribution of available Copper in different soil depths as influenced by the graded level of crop residues and residual starter zinc under rice-wheat cropping system in calcareous soil are presented. The data on depth wise distribution of available Copper as influenced by long term application of crop residue and residual starter Zn under rice-wheat cropping system are depicted and illustrated i. It was recorded an increase in 15-30 cm depth (3.13 to 3.68 mg kg-1) in comparison to 0-15 cm depth (3.10 to 3.65 mg kg-1) and further it was decreased in 30-60 cm (3.08 to3.61 mg kg-1) and 60-90 cm depth (3.07 to 3.54 mg kg-1) as influenced by crop residue but with increasing level of residual starter Zn, the availability of Cu was decreased in all depths as 0-15 cm depth (3.40 to 3.31 mg kg-1), 15-30 cm (3.44-3.34 mg kg-1). 30-60 cm (3.36 - 3.27 mg kg-1) and 60-90 cm (3.33-3.23 mg kg-1) but among all depths, Cu was high in 15-30 cm of depth.
