ABSTRACT
A field experiment entitled “Integrated plant nutrient supply system (IPNSS) for sustaining yield of hybrid maize” variety, Kaveri super - 244 was carried out under field conditions of sandy clay loam soil during kharif season at farmer’s field, Kalappanaickenpatti village, Sendamangalam block, Namakkal district of Tamil Nadu during July - October 2021. The experiment was laid out in randomized block design with three replication and ten treatments. Growth parameters and yield of maize viz., plant height, leaf area index, dry matter production, grain yield and stover yield was significantly responded better in all treatments at 30, 60 DAS and harvest days after sowing. Where, T8 – 100 per cent RDF + CPM @ 3 t ha-1 + Micronutrient mixture (25 kg ha-1) + Azophos (20 packets) depicted better peformance than other treatments.
