Abstract
A field study was carried out at farmer’s field, Kalappanaickenpatti village, Sendamangalam block, Namakkal district of Tamil Nadu during July - October 2021 to study the effect of Integrated plant nutrient supply system (IPNSS) for sustaining yield of hybrid maize variety, KAVERI SUPER – 244 in clay loam soil. There are ten different treatments with three replications each were carried out in the plot RBD design. IPNSS practice including inorganic fertilizers, organic manures and biofertilizers in which treatment (T8) 100 per cent RDF + CPM @ 3 t ha-1 + Micronutrient mixture (25 kg ha-1) + Azophos (20 packets) showed its best results with respect to soil properties and yield parameters like cob length, cob diameter, number of grain cob-1, test weight and harvest index.
