The present investigation was carried out with cabbage cv. Pusa Mukta in a randomized complete block design with three replications with the objective to evolve integrated plant nutrient supply system for higher productivity of cabbage on sustainable basis. The experiment comprised of 15 different combinations of three different sources of nutrients including organic, inorganic and PGPR alone and in combinations which were applied following the proper procedures as per treatment. Integrated use of fertilizers, manures and PGPR significantly influenced yield and plant growth attributes of cabbage crop. The conjoint use of 75% recommended dose of NP + Vermi compost and Enriched compost @ 2.5 t/ha + PGPR (T14) resulted in significantly maximum gross head weight (1580 g), net head weight (1050 g), harvesting index (66.45%) and head yield (530.34 q/ha). This treatment recorded 34.4 per cent increase in yield over recommended practice (T1) along with highest net returns (Rs.3, 89,992/-). From present investigation, it can be concluded that above integrated combination of chemical fertilizers, organic manures (VC and EC) and PGPR resulted in saving of 25% chemical fertilizers (NP), better growth, higher yield which statistically matched with the recommended package of fertilization which utilized 100% NPK along with 20 t FYM.
