Abstract:
A field experiment entitled “Dynamics of soil carbon under integrated nutrient management practices in maize - groundnut cropping sequence” was carried out under field conditions during both Kharif and Rabi seasons of 2019-2020 and 2020-2021 at Field No. 50B of Wetland Farm, S.V. Agricultural College, Tirupati campus (under the judicatory of Acharya N.G. Ranga Agricultural University) Growth parameters of maize viz., plant height, dry matter accumulation and Chlorophyll content at tasselling was significantly higher in interaction with where 125% RDF + 10 FYM (M₁S₂) and was on par with the 125% RDF + Poultry manure @ 5 tons ha^-1 (M₁S₃). Growth and physiological parameters viz., plant height, dry matter accumulation significantly influenced at 30, 60, 90 DAS and harvest days after sowing during both the years and Chlorophyll content was recorded at tasselling stage in both the years there was a significant results were found in subplots in both years and highest was found in application of poultry manure 5 ton per ha.
